When the rectangular block resists the limit block and moves toward the inside of the cavity, the second spring is compressed by the limit block. When the rectangular block is fully installed into the inside of the rectangular groove, the limit block is reset under the action of the compressed second spring, so that the limit block is quickly stuck into the inside of the slot, and the second spring can prevent the limit block from loosening.

[0016] Preferably: the adjustment assembly includes a screw threadedly connected to the outer wall of the base, the end of the screw is fixedly connected to the first gear, and the side wall of the base plate is provided with a threaded groove adapted to the screw. When the base plate is installed inside the base, the first gear is rotated to drive the screw to rotate, so that the screw is inserted into the inside of the threaded groove, thereby strengthening the fixation of the base plate and preventing the base plate from loosening.

[0017] Preferably, a rotating rod is fixedly connected to the eccentric portion of the side wall of the first gear and the turntable. When the turntable and the first gear need to be rotated, only the rotating rod needs to be rotated, thereby achieving the purpose of convenience.
