[0048] S2. During the movement of the connecting plate 302, the first connecting column 504 and the first ball 505 are driven to move, so that the first ball 505 is inserted into the position between the first rotating block 503 and the second rotating block 509. At this time, the first rotating block 503 and the second rotating block 509 are subjected to pressure, and at the same time, the first rotating plate 502 and the second rotating plate 508 are driven to rotate in the opposite direction to the outer wall. While rotating, the third spring 506 is driven to contract. When the first ball 505 is fully inserted, the first ball 505 is clamped to a certain extent through the first rotating block 503 and the second rotating block 509.

[0049] S3. During the movement of the connecting plate 302, the second connecting column 601 and the second ball 602 are driven to move, so that the second ball 602 is inserted into the first toothed plate 303. When the second ball 602 contacts the arc block 604, it drives the fourth spring 603 to shrink backward. When the second ball 602 passes through the arc block 604, the arc block 604 limits the second ball 602 to a certain extent through the rebound of the fourth spring 603.

[0050] S4.
