[0025] The clamping mechanism 2 comprises a mounting sleeve 22, the top of the mounting sleeve 22 is fixedly connected with the top of the base 1, mounting plates 21 are fixedly connected to the top of the mounting sleeve 22 on both sides, and a bent rod 26 is hingedly connected to the mounting plates 21 on both sides, a hinge block 27 is hingedly connected to the bottom end of the bent rod 26, a moving block 25 is hingedly connected to the bottom of the hinge block 27, a threaded rod 23 is threadedly connected to the middle of the moving block 25, the threaded rod 23 is rotatably connected to the middle of the mounting sleeve 22, a clamping block 28 is hingedly connected to the top end of the bent rod 26, a hinge strip 29 is hingedly connected to the inner side of the bottom of the clamping block 28, and the bottom of the hinge strip 29 is hingedly connected to the outer side of the mounting plate 21.

[0026] When the threaded rod 23 is rotated, the moving block 25 can be lifted up and down on the threaded rod 23 through the clamping mechanism 2 arranged, at this time, because the mounting plate 21 and the elbow rod 26 are hingedly connected in the middle, when the moving block 25 is lifted up and down, because the hinged block 27 at the bottom end of the elbow rod 26 and the moving block 25 are hingedly connected on both sides, the moving block 25 can make the elbow rod 26 flip inward and outward during lifting up and down, so that the clamping block 28 can flip inward and outward under the cooperation of the hinged strip 29, so as to realize clamping of the inner and outer rings, and because the moving range of the moving block 25 is limited during clamping, the clamping of the clamping block 28 can be realized, and the clamping force of the clamping block 28 can be ensured not to be too large, effectively solving the problem that the clamping force of the tiger stool is too large, which easily leads to deformation of the inner and outer rings, and such deformation affects the precision and performance of the bearing 24.
