A movement control device, applicable to a first object and a second object movable relative to the first object, the movement control device comprising: a first blocking member arranged on one of the first object and the second object, the first blocking member comprising a first blocking part and a second blocking part; a supporting plate fixed to the other one of the first object and the second object; and a second blocking member arranged on the supporting plate and movable relative to the supporting plate between an initial position and a blocking position; wherein when the second object is moved relative to the first object along a first direction and the second blocking member is moved from the initial position to the blocking position, the second 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 along the first direction; wherein the second blocking member has a stopping feature corresponding to the first blocking member. wherein the movement control device further; comprises a first part fixed to the supporting plate, a second part movably arranged on the supporting plate, and an actuating member arranged between the first part and the second part; wherein the actuating member is configured to be moved from a first position to a second position in response to relative movement between the first part and the second part, in order to drive the second blocking member to move from the initial position to the blocking position; wherein when the movement control device is shaken or tilted, a direction of the relative movement between the first part and the second part is different from a direction of the actuating member being moved from the first position to the second position; and wherein the second blocking member has a guiding section corresponding to the actuating member, the actuating member is configured to drive the second blocking member to move from the initial position to the blocking position through the guiding section; wherein the direction of relative movement between the first part and the second part 40 is a horizontal direction, and the direction of movement of the actuating member is a vertical direction; and wherein the second blocking member is movably arranged on the first part. a first blocking member arranged on one of the first object and the second object, the first blocking member comprising a first blocking part and a second blocking part; a supporting plate fixed to the other one of the first object and the second object; and a second blocking member arranged on the supporting plate and movable relative to the supporting plate between an initial position and a blocking position; wherein when the second object is moved relative to the first object along a first direction and the second blocking member is moved from the initial position to the blocking position, the second 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 along the first direction; wherein the second blocking member has a stopping feature corresponding to the first blocking member. wherein the movement control device further; comprises a first part fixed to the supporting plate, a second part movably arranged on the supporting plate, and an actuating member arranged between the first part and the second part; wherein the actuating member is configured to be moved from a first position to a second position in response to relative movement between the first part and the second part, in order to drive the second blocking member to move from the initial position to the blocking position; wherein when the movement control device is shaken or tilted, a direction of the relative movement between the first part and the second part is different from a direction of the actuating member being moved from the first position to the second position; and wherein the second blocking member has a guiding section corresponding to the actuating member, the actuating member is configured to drive the second blocking member to move from the initial position to the blocking position through the guiding section; wherein the direction of relative movement between the first part and the second part 40 is a horizontal direction, and the direction of movement of the actuating member is a vertical direction; and wherein the second blocking member is movably arranged on the first part.
