US Patent 10258155 Movement control device for part assembly

A movement control device is applicable to a first object and a second object movable relative to the first object. One of the first object and the second object is arranged with a first blocking part and a second blocking part, and the other one of the first object and the second object is movably arranged with a blocking member. When the second object is moved relative to the first object and the blocking member is moved from an initial position to a blocking position, the blocking member is configured to block one of the first blocking part and the second blocking part, in order to prevent the second object from being moved relative to the first object.
