[0025] like Figure 1 and Figure 4As shown, the pressing mechanism 6 includes a pressing plate 601, a guide rod 602 and a return spring 603. The guide rod 602 and the return spring 603 are symmetrically arranged. The top of the guide rod 602 is fixedly connected to the bottom end of the pressing plate 601, and the bottom end of the guide rod 602 is movably connected to the inside of the bracket 5.

The opposite side of the slide rail 1 is fixedly connected to the support plate 9. The top of the support plate 9 is fixedly connected to a hydraulic cylinder 10, and the telescopic end of the hydraulic cylinder 10 is fixedly connected to a bracket 11. The bracket 11 is concave in shape, and the top of the bracket 11 is fixedly connected to a group of symmetrical pressure rods 12.

[0026] The position of the bracket 5 is adjusted according to the length of the pipe 2 so that the bracket 5 is close to the end of the pipe 2. By pulling the adjusting rod 803 outward, the moving rod 802 squeezes the compression spring 15, driving the tooth block 801 away from the tooth plate 7, and then pushing the bracket 5 to move along the slide rail 1 until the bracket 5 moves to the end of the pipe 2.
