The displacement telescopic rod 71 works to push the self-moving vehicle 7 to move to one side of the first limit position. It is worth noting that in the present embodiment, it is also proposed that a motor 1 for driving the pipe withdrawal cam 73 to rotate is fixedly installed on the outer wall of the self-moving vehicle 7, and a motor 2 for driving the gear 76 to rotate is fixedly installed on the rear side of the support frame 72. The motor 1 is started to drive the pipe withdrawal cam 73 to rotate, so that the support frame 72 can retreat a distance, and the two ends of the PVC drainage pipe body 1 are installed on the outside of the clamping plate 742 in the pipeline. The motor 1 drives the pipe withdrawal cam 73 to rotate in the opposite direction to extrude the support frame 72 forward so that the pipeline end mold 74 clamps the two ends of the pipeline. In addition, the present embodiment also proposes that the opposite sides of the pipeline end mold 74 are respectively provided with grooves and grooves that are compatible with the sealing ring 22 and the sealing groove 23. The convex ring is convenient for forming the sealing ring 22 and the sealing groove 23. The double-headed telescopic rod 741 works to expand the clamping plate 742 in the pipe to clamp and fix the inner wall of the PVC drainage pipe body 1. The displacement telescopic rod 71 continues to push the self-moving vehicle 7 to move to the second extreme position to complete the injection molding and demolding of the shock-absorbing and pressure-resistant protective sleeve 2.
