[0023] When in use, the PVC pipe is input between the conveyor belts 6 on both sides, and then the conveyor belts 6 are moved by the motor 3, so as to achieve the traction of the PVC pipe. During traction, the spacing between the movable seats 11 can be adjusted according to the actual size of the PVC pipe, so as to better clamp the PVC pipe.

[0024] As a further implementation of this embodiment, Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the output end of the motor 3 is connected to a transmission roller 4, and a stop column 5 is distributed on one side of the transmission roller 4.

A return spring 10 is provided on the inner side of the rubber seat 7, and the other end of the return spring 10 is fixedly connected to a movable seat 11. The movable seat 11 is slidably connected to the rubber seat 7 through a guide block 12, and the guide block 12 is symmetrically distributed along the vertical center line of the movable seat 11. The side wall of the movable seat 11 A guide block 12 is fixedly installed, an arc-shaped protrusion 13 is arranged on the top of the movable seat 11, and the arc-shaped protrusion 13 is equidistantly distributed along the surface of the movable seat 11, and the arc-shaped protrusion 13 and the movable seat 11 form an integrated structure, a first card groove 14 is opened on the side wall of the blocking column 5, and a thread groove 15 is connected to one side of the first card groove 14, a second card groove 16 is opened on the side wall of the driving roller 4, a mounting plate 17 is distributed on the side of the conveyor belt 6 away from the side plate 2, and a first card block 18 is fixedly installed in the middle of one side of the mounting plate 17, and a second card block 19 is distributed on the other side of the first card block 18, a positioning bolt 20 is penetrated through the middle section of the other side of the mounting plate 17, and an auxiliary rod 21 is distributed on one side of the side plate 2;
