The rotating block 3 can be driven to rotate by controlling the upper end of the rotating handle 2, and the rotation angle is limited by the handle slot 12.

[0031] Slide grooves 32 are formed on both sides of the rotating block 3 and the two slide grooves 32 are parallel to each other.

[0032] The limiting mechanism 4 includes a plug 41, an elastic component 42 and a pressing block 43. The plug 41 is fixedly installed in the limiting groove 11 at one end away from the rotating block 3. One end of the elastic component 42 is fixedly connected to the plug 41, and the other end is fixedly connected to the pressing block 43.
