[0029] Furthermore, the threads at both ends of the inner wall of the threaded barrel 25 are in opposite directions, and a rectangular opening is provided at the bottom of the long box 1 so that the two threaded rods 26 can move in opposite directions.

[0030] Furthermore, the outer shape of the threaded block 28 matches the shape of the inner wall of the long box 1 , and the threaded block 28 is slidably connected to the inner wall of the long box 1 , so that the threaded block 28 can move stably.

[0031] Furthermore, an opening is provided on the top of the long box 1, and the rectangular long block 29 is moved through the opening. The rectangular long block 29 is fixedly connected to the bottom of the support platform 4, so that the rectangular long block 29 can be stably moved through the opening.

[0032] Furthermore, a rotation hole is opened inside the fixing frame 27 , and the threaded barrel 25 is rotatably connected to the inner wall of the rotation hole, thereby providing stable support for the threaded barrel 25 .

[0033] Furthermore, the transmission assembly 24 includes a driving gear and a driven gear, the threaded barrel 25 is fixedly connected to the inner ring of the driven gear, the output shaft 23 is fixedly connected to the inner ring of the driving gear, and the driving gear and the driven gear are meshed with each other to achieve the purpose of stable transmission.

[0034] Example 2

[0035] See Figures 1 to 4 On the basis of the first embodiment, the clamping mechanism 3 further includes a fixing groove 31, the fixing groove 31 is fixedly connected to the top of the support platform 4, the inner wall of the fixing groove 31 is fixedly connected to a telescopic rod 32, the top of the telescopic rod 32 is fixedly connected to a slider 33, the front of the slider 33 is fixedly connected to a first clamping block 34, and the top of the support platform 4 is fixedly connected to a second clamping block 35, which is convenient for ensuring stability during the early pipe testing process.
