The bottom of the first protective cover 201 is fixed on the lifting platform 104, the second protective cover 202 is hinged with the first protective cover 201, and the driving motor 203 is fixed on the lifting platform 104. The top of the first protective cover 201 is open, a semicircular groove 201a is formed in the top of the first protective cover 201, a bearing 201b is arranged in the semicircular groove 201a, and a motor shaft 204 of the driving motor 203 penetrates through the bearing 201 b; the motor shaft 204 is provided with a circular boss 205, and the cutting wheel 207 is fixed on the circular boss 205 through a fastener 206.

In particular, the cutting wheel 207 may be a grinding wheel.

It should be noted that the profile is disposed on the placing layer 103 and fixed on the placing layer 103 by a holding device, as shown in fig. 1.

Specifically, the placing layer 103 is provided with a saw cut corresponding to the open position of the first protective cover 201, and the overall height of the cutting assembly 200 can be adjusted by adjusting the height of the lifting table 104. During operation, the lifting platform 104 is raised, the cutting wheel 207 penetrates through the saw cut, and the section bar fixed on the placing layer 103 is cut.

It should be noted that the second protection cover 202 is connected to the bottom, as shown in fig. 2, the cutting wheel 207 passes through the second protection cover 202, the second protection cover 202 and the first protection cover 201 can shield most of the cutting wheel 207, and the edge of the cutting wheel 207 is left, so that the edge of the cutting wheel 207 can pass through the saw kerf to perform the cutting operation, and the safety is high.

Referring to fig. 3 and 6, a side groove 205a is formed in one side of the circular boss 205 inward, an accommodating groove 205b is formed in the circular boss 205 in the radial direction, and the accommodating groove 205b communicates with the side groove 205 a. The receiving groove 205b is provided with an insert 205c, a wall surface of the insert 205c near the outer edge of the circular boss 205 is connected to the bottom of the receiving groove 205b through a spring 205d, and another wall surface of the insert 205c is an inclined surface, i.e., a first inclined surface 205 c-1. The first inclined surface 205c-1 is disposed at one corner of the end of the insert 205c, and has a triangular shape, and three vertexes thereof are located on three edges at one corner of the insert 205 c. It should be noted that the insert 205c is limited to be linearly movable only in the radial direction of the receiving groove 205b, i.e., the circular boss 205. In the initial state, i.e., when the spring 205d is in the natural state, the end of the insert 205c extends out of the receiving groove 205b and is located in the side groove 205 a.

Referring to fig. 3 and 7, the fastener 206 includes a screw-in end 206a and a baffle 206b, the baffle 206b is disposed at the end of the screw-in end 206a, and an insertion groove 206d is disposed on the outer side of the screw-in end 206 a; the fastener 206 is provided with a through hole 206c, the inner wall of the through hole 206c is provided with a spiral strip 206e, the outer surface of the motor shaft 204 is provided with a spiral groove 204a, and when the motor shaft 204 is stopped and fixed, the spiral strip 206e is screwed into the spiral groove 204a, so that the fastener 206 is sleeved on the motor shaft 204.

When the fastener 206 is screwed on the motor shaft 204, the screw-in end 206a enters the side groove 205a and contacts the first inclined surface 205c-1 to push the first inclined surface 205c-1, so as to push the insert 205c integrally to move outward along the radial direction of the circular boss 205, the spring 205d is compressed, and when the fastener is screwed into the position of the insert groove 206d and corresponds to the position of the insert 205c, the insert 205c is ejected into the insert groove 206d under the action of the spring 205 d. It should be noted that the slot 206d is in the path of the helical strip 206e and that the slot 206d is sized to fit the size of the slug 205 c.

The matching structure of the spiral groove 204a and the spiral strip 206e is that rotation and linear motion are performed simultaneously, and when the arbitrary degree of freedom of the rotation and the straight line of the buckling piece 206 is limited, the fixation is realized, which is embodied as: the engaging member 206 is limited in the axial direction so as not to move linearly, or the engaging member 206 is limited in the circumferential direction so as not to rotate. Due to the matching of the spiral groove 204a and the spiral strip 206e, the requirement for the size matching between the insert block 205c and the insert groove 206d is reduced, when the first wide side a1 of the insert block 205c and the second wide side a2 of the insert groove 206d are matched in size, the fastener 206 is fixed in the axial direction, at this time, the requirement for the matching between the first long side b1 of the insert block 205c and the second long side b2 of the insert groove 206d can be reduced, and the fastener 206 can still be fixed with the round boss 205; or the first long side b1 of the insert 205c and the second long side b2 of the insert groove 206d are matched in size, so that the fastener 206 cannot rotate relative to the circular boss 205; similarly, even if the requirement for the first wide side a1 of the insert 205c and the second wide side a2 of the slot 206d is reduced, the fastener 206 can be secured to the circular boss 205.

Referring to fig. 3, a slot 205e is formed in a side surface of the circular boss 205, and the slot 205e is communicated with the receiving groove 205 b. It should be noted that the direction of the slot 205e is along the axial direction of the motor shaft 204, and the receiving slot 205b is along the radial direction.

Referring to fig. 3, 4, 6 and 7, pushing grooves 205c-2 are formed in two sides of the insert 205c, a second inclined surface 205c-3 and a first flat surface 205c-4 are formed in one side of the pushing groove 205c-2, and the pushing groove 205c-2 corresponds to the insertion groove 205 e; the motor shaft 204 is further provided with an unlocking piece 208, the unlocking piece 208 comprises a circular ring 208a and an inserting strip 208b, the circular ring 208a is sleeved on the motor shaft 204, and the inserting strip 208b is inserted into the inserting groove 205 e; the end of the cutting bar 208b is provided with a third inclined surface 208b-1 and a second flat table surface 208b-2, and the third inclined surface 208b-1 is arranged in parallel with the second inclined surface 205 c-3.

The installation process of the invention is as follows: the cutting wheel 207 is sleeved on the motor shaft 204, and then the fastener 206 is screwed on the motor shaft 204 until the insert 205c is inserted into the insert groove 206 d.

When disassembly is required, the unlocking piece 208 is pushed to enable the inserting strip 208b to be inserted into the pushing groove 205c-2, in the inserting process, the third inclined surface 208b-1 firstly contacts the second inclined surface 205c-3 and pushes the second inclined surface 205c-3 to move, so that the inserting strip moves outwards along the radial direction of the circular boss 205, the spring 205d is compressed, when the first flat platform surface 205c-4 is lapped on the second flat platform surface 208b-2, the embedded block 205c completely leaves the embedded groove 206d, at the moment, the buckling piece 206 can be taken out, the cutting wheel 207 can be taken down together with the buckling piece 206, and particularly, the cutting wheel 207 is pushed towards the direction of the buckling piece 206.

It should be noted that the above-mentioned embodiments are only for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, which should be covered by the claims of the present invention.
