The setting of the device avoids the use of rope winding to move the extrusion plate up and down, avoids the problem of the device being unusable after the rope breaks, and improves the stability of the device.

[0004] When the device is in use, the second wedge-shaped block that moves left and right cooperates with the retracting rod and the spring to drive the lifting rod and the extrusion plate to move up and down, thereby fixing the PVC pipe. However, the spring is always in an extruded state while the PVC pipe is fixed, which makes the spring easy to deform during long-term use, and then the elastic force of the extrusion plate is weakened, resulting in the extrusion plate being unable to fix the PVC pipe well, affecting the marking of the PVC pipe.
