In practical use, the second winding wheel 221 driving mechanism is preferably a self-locking motor. Compared with the state switching of the lock lever 2121, the working position switching stroke of the rotating member 213 is larger (the moving distance of the second rope 222 is larger), if the cylinder or the electric push rod is adopted, the required size length is larger, the self-locking motor can effectively reduce the length, and in addition, the second rope 222 can be limited by self-locking, namely, a two-way lock structure is formed, so that the rotating member 213 is prevented from unlocking due to the unexpected switching of the lock lever 2121 to the second state.

The foregoing description is only of the preferred embodiments of the present utility model, and is not intended to limit the scope of the utility model, but rather is intended to cover all equivalent structures as modifications within the scope of the utility model, either directly or indirectly, as may be contemplated by the present utility model.
