[0038] Working principle:

[0039] The first clamping block 11 and the second clamping block 12 are then clamped together, and the handle 14 is rotated to make the handle 14 drive the extension rod 13 to rotate. The rotation of the extension rod 13 drives the first clamping block 11 and the second clamping block 12 to rotate, thereby making the first clamping block 11 drive the threaded rod 9 to rotate, and the rotation of the threaded rod 9 drives the two clamping blocks 10 to open and close. Then, the lifting block 7 is pressed down, so that the lifting block 7 drives the pressing block 6 to press down, thereby making the spring 4 and the telescopic rod 5 move downward, so that the spring 4 undergoes elastic deformation to press the base 3 and the bearing body 2 downward, thereby limiting the bearing body 2.
