As an embodiment of the present invention, the outer surface of the movable rod 145 is provided with a thread, the movable block 142 is in threaded connection with the second slider 15 through the thread, a spring roll 146 is fixedly connected to a position of the outer surface of the movable rod 145 near to both ends, the top end of the inner surface of the first chute 12 is provided with a third chute 121, a third slider 122 is slidably connected inside the third chute 121, the third slider 122 is fixedly connected with the first slider 13, one end of the spring roll 146 is fixedly connected with the movable rod 145, the other end of the spring roll 146 is fixedly connected with a connecting rope 147, one end of the connecting rope 147 is fixedly connected with the spring roll 146, and the other end of the connecting rope 147 penetrates through the inside of the third chute 121 and is fixedly connected with the third slider 122.

In the using process, when the pipe body 2 is shaken or slightly vibrated due to the impact of the tap water inside the pipe body, the pipe body 2 extrudes the first oil absorption cotton 17 towards two sides, so that the protective oil inside the first oil absorption cotton 17 is smeared on the surface of the pipe body 2 due to the effect of pressure, the pipe body 2 is maintained, the service life of the pipe body 2 is ensured, but in the actual using process, the first oil absorption cotton 17 cannot move, the uniformity in the smearing process of the protective oil is reduced, and the waste of the protective oil is easily caused, therefore, by arranging the spring roll 146 and the connecting rope 147, when the first arc-shaped plate 33 and the second arc-shaped plate 34 move towards the pipe body 2 to extrude the arc-shaped elastic sheet 35 to push the first connecting plate 31 and the second connecting plate 32 to move towards two sides, the connecting block 36 drives the first sliding block 13 and the third sliding block 122 to move inside the first sliding groove 12, so as to pull the connecting rope 147, the connecting rope 147 is used for pulling the movable rod 145 to rotate, when the external pressure is weakened, the first arc-shaped plate 33 and the second arc-shaped plate 34 drive the connecting block 36 and the first sliding block 13 to move towards the direction close to each other under the action of the arc-shaped elastic sheet 35, meanwhile, the connecting rope 147 is wound towards the movable rod 145 under the action of the spring roll 146, the movable rod 145 rotates forwards and backwards in the process, and the movable rod 145 is in threaded connection with the second sliding block 15, so that the second sliding block 15 drives the arc-shaped mounting plate 16 to move along the surface of the pipe body 2 to wipe and maintain the pipe body during the forward and backward rotation of the movable rod 145.

The working principle is as follows: in the installation process, the bottom plate 1 is fixed underground, then the pipe body 2 penetrates through the first arc-shaped notch 11, the first connecting plate 31 and the second connecting plate 32 are placed on the outer surface of the upper end of the bottom plate 1, the connecting block 36 corresponds to the first sliding block 13, the bolt 38 penetrates through the threaded hole 37 and extends into the first sliding block 13, so that the first sliding block 13 is connected with the connecting block 36, as the first arc-shaped plate 33 and the second arc-shaped plate 34 are respectively hinged with the first connecting plate 31 and the second connecting plate 32, and the first arc-shaped plate 33 is hinged with the second arc-shaped plate 34, when pressure is generated to the device by external pressure, the first arc-shaped plate 33 and the second arc-shaped plate 34 move towards the pipe body 2 to extrude the arc-shaped elastic sheet 35 to push the first connecting plate 31 and the second connecting plate 32 to move towards two sides, under the action of high elasticity of the arc-shaped elastic sheet 35, the pressure applied to the device is buffered, thereby improve the stability of body 2 and protect it, through setting up protection machanism 3, can protect it when fixing body 2, utilize arc shell fragment 35 can effectually alleviate the external pressure that produces to reduce the cracked probability of body 2, guarantee the normal transport of running water, increase body 2's life.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
