[0020] In this embodiment, the outer wall of the fixing plate 1 is connected to the fixing seat 2 by bolts, the fixing seat 2 is fixedly mounted with a cylinder 3, the output end of the cylinder 3 is mounted with a sleeve 4, and one end of the sleeve 4 is mounted on one end of the limiting seat 5.

[0021] Specifically, the extension and retraction of the cylinder 3 can drive the limit seat 5 on one side of the sleeve 4 to move, so as to clamp or release the limit.

[0022] In this embodiment, two groups of turntables 9 are arranged outside the placement hole, and a threaded guide groove is arranged on the inner wall of one side of the turntable 9. A limit bolt 10 is threadedly arranged in the threaded guide groove.

[0023] Specifically, after the inner wall of the component is clamped by the limiting seat 5, the turntable 9 can be rotated to the front end surface of the component, and the limiting bolt 10 can be driven to press against the surface of the component through the rotation of the limiting bolt 10.

[0024] In this embodiment, a top block 12 is sleeved on the outer wall of one end of the limiting bolt 10 .

[0025] Specifically, when the limiting bolt 10 rotates, the front end surface of the component is fixed and limited by the provided top block 12, so that the limiting bolt 10 can be prevented from directly contacting the component and damaging its surface.
