The number of the clamping mechanisms 3 is two, and the two clamping mechanisms 3 are symmetrically arranged.

[0034] Through the above structural design, it can be known that the steel pipe can be clamped and fixed by the two clamping mechanisms 3, the position of the combination mechanism 7 can be moved by the two moving mechanisms 6, and then the steel pipe clamped by the two clamping mechanisms 3 can be expanded by moving the combination mechanism 7.

[0035] Specifically, the clamping mechanism 3 includes a connecting frame 9, both ends of the lower end of the connecting frame 9 are fixedly connected with a first slider 10, first slide grooves 4 are opened on both sides of the upper end of the workbench 1 and at positions corresponding to the first slider 10, the first slider 10 is slidably connected to the first slide groove 4, second slide grooves 5 are opened on both sides of the workbench 1 and at positions corresponding to the first slide grooves 4, the second slide grooves 5 are connected to the first slide grooves 4, a first screw rod 12 is threadedly connected at a middle part of the first slider 10 and at a position corresponding to the second slide groove 5, one end of the first screw rod 12 away from the first slider 10 extends from the position of the second slide groove 5 to the outside of the workbench 1 and is fixedly connected with a first handle 11, and a clamping assembly 13 is arranged in the middle part of the upper end of the connecting frame 9.
