The connecting column 414, at this time, due to the elasticity of the connecting spring 408, the connecting column 414 is reset and connected to the corresponding connecting hole 412, and the operation is simple and convenient. When the splint 409 moves, the connecting seat 411 is driven to move, thereby squeezing the bottom end of the squeezing plate 410, so that the squeezing plate 410 rises. When the squeezing plate 410 rises, the brush plate 404 is driven to rise, so as to wipe the side of the splint 409 that clamps the metal pipe, thereby preventing some dust from affecting the state of the pipe during processing.

When the bottom plate 505 contacts the ground, the threaded rod 502 is released. The contact area between the device as a whole and the ground can be increased by setting the bottom plate 505, thereby increasing the stability of the device and making the equipment more stable during operation.
