The rotating shaft of the rotating seat 9 abuts against the front end of the self-locking top screw 11, and then the limiting is realized according to the requirement.

[0046] Structural cooperation:

[0047] The surface of the rotating shaft of the rotating seat 9 is provided with an annular groove or a plane structure, and the front end of the self-locking top screw 11 is embedded in the structure, so that the displacement of the rotating shaft after locking is further prevented.

[0048] The height adjusting seat 10 adopts a dovetail groove or a precision guide rail structure, so that the contact surface of the self-locking top screw 11 and the rotating seat 9 is kept stable and aligned.

[0049] Operation process:

[0050] After the rotating seat 9 is adjusted to the target angle, the self-locking top screw 11 is manually tightened, the front end of the self-locking top screw 11 abuts against the rotating shaft to generate friction resistance, and rigid locking is realized.

[0051] In the locking process, the limiting block 14 cooperates with the limiting top screw to limit the extreme angle range of the rotating seat 9, avoiding the failure of self-locking caused by overload.

[0052] Precision guarantee:
