thereby improving the cutting precision, realizing better cutting effect, the press rod 5 rotates to different distances, thereby adjusting the distance of the cutting disc 9 cutting into a workpiece, thereby adjusting the cutting depth, improving the practicability, the press rod 5 rotates to stretch the first spring 6, when the movable plate 1 moves, the drive connecting rod 26 moves, the connecting rod 26 drives the roller 28 to rotate, the contact area with the workpiece is reduced through the roller 28, thereby reducing the friction, thereby reducing the vibration caused by the friction force, thereby reducing the vibration deviation of the workpiece, thereby improving the cutting precision, here, the press rod 5 moves downwards, the positioning tube 10 is driven to move downwards, the positioning tube 10 drives the second spring 12 to move downwards, the second spring 12 drives the positioning rod 11 to move downwards, the positioning rod 11 drives the walking plate 15 to move downwards, the walking plate 15 drives the sand skin 16 to move downwards, so that the sand skin 16 is abutted against the cutting part of the workpiece, along with the continuous downward pressing of the press rod 5, the sand skin 16 is abutted against the workpiece and cannot move, so that the walking plate 15 and the positioning rod 11 cannot move, so that the positioning tube 10 moves downwards, so that the second spring 12 is compressed, the restoring force of the second spring 12 generates downward thrust to the positioning rod 11, the positioning rod 11 generates downward

meanwhile, the walking plate 15 is used for pressing the workpiece to realize auxiliary clamping on the workpiece, so that the workpiece is better prevented from moving, better cutting precision is realized, and better grinding effect is realized, meanwhile, the motor 7 drives the driving shaft 8 to rotate, the driving shaft 8 drives the first rotating wheel 19 connected with the driving shaft

the walking plate 15 reciprocates, so that the abrasive belt 16 reciprocates back and forth on the cutting part of the workpiece, so that a better grinding effect is realized, then along with pushing of the pressure lever 5, the pressure lever 5 pushes the grinding mechanism to move, so that the abrasive belt 16 moves along the cutting part, so that the cutting part of the whole workpiece is ground, here, a belt between the two second rotating wheels 20 is always in a stretched state, so that the belt has enough friction force to drive the two second rotating wheels 20 to rotate, meanwhile, the restoring force of the belt between the two second rotating wheels 20 is smaller than that of the third spring 17, so that the belt cannot drive the positioning rod 11 to move into the positioning pipe 10, when cutting is stopped, the handle 32 is released, so that the pressing lever 5 is reversely rotated by the restoring force of the first spring 6, so that the cutting unit is
