As shown in fig. 2 and 3, when the sliding member 22 moves from the first position to the second position along the chute 11, that is, from the state shown in fig. 2 to the state shown in fig. 3, the sliding member 22 drives the limiting member 21 to rotate relative to the rotating shaft 24 in a direction away from the sliding member 22, so that the first limiting portion 221 is separated from the second limiting portion 211, thereby separating the sliding member 22 from the bracket 10, and enabling the elastic member 23 to be in a compressed state.

When the sliding member 22 moves from the second position to the first position along the chute 11, that is, from the state shown in fig. 3 to the state shown in fig. 2, the elastic member 23 moves toward the direction approaching the sliding member 22 under the action of the elastic restoring force, and drives the limiting member 21 to rotate toward the direction approaching the sliding member 22 relative to the rotating shaft 24 until the sliding member 22 moves to the state shown in fig. 2, so that the first limiting portion 221 is in limiting fit with the second limiting portion 211, and the sliding member 22 and the bracket 10 are locked and fixed.

In some alternative embodiments, the elastic member 23 includes a fixing portion 231 and an elastic portion 232, and the fixing portion 231 is connected to the bracket 10, thereby fixing the elastic member 23 to the bracket 10. The first end of the elastic portion 232 is connected to the fixing portion 231, and the second end of the elastic portion 232 extends in a direction approaching the stopper 21 and abuts against the second end of the stopper 21.

As shown in fig. 2 and 3, when the sliding member 22 moves from the first position to the second position along the chute 11, that is, from the state shown in fig. 2 to the state shown in fig. 3, the sliding member 22 drives the limiting member 21 to rotate relative to the rotating shaft 24 in a direction away from the sliding member 22, so that the first limiting portion 221 is separated from the second limiting portion 211, thereby separating the sliding member 22 from the bracket 10, and driving the elastic portion 232 of the elastic member 23 to move in a direction approaching the fixing portion 231, so that the elastic portion 232 of the elastic member 23 is in a compressed state.

When the sliding member 22 moves from the second position to the first position along the chute 11, that is, from the state shown in fig. 3 to the state shown in fig. 2, the elastic portion 232 of the elastic member 23 moves in a direction away from the fixing portion 231 (that is, in a direction approaching to the sliding member 22) under the action of the elastic restoring force, so as to drive the limiting member 21 to rotate relative to the rotating shaft 24 in a direction approaching to the sliding member 22 until the sliding member 22 moves to the state shown in fig. 2, so that the first limiting portion 221 is in limiting fit with the second limiting portion 211, and the sliding member 22 and the bracket 10 are interlocked and fixed.

In this embodiment, the elastic member 23 may be a spring piece. In other examples, the elastic member 23 may be a return spring, and the bracket 10 may be provided with a receiving cavity in which the return spring is received, and one end of the return spring abuts against the bottom of the receiving cavity, and the other end abuts against the second end 213 of the limiting member 21.

In some optional embodiments, the limit groove is a trapezoid groove, and the limit bump is a trapezoid structure with shape matching with the limit groove. The opening size of the limiting groove is larger than the bottom wall size of the limiting groove. Correspondingly, the size of the end part of the limit lug, which is close to one side of the limit groove, is smaller than that of the end part of the limit lug, which is far away from one side of the limit groove, so as to be matched with the limit groove. The limit groove adopts trapezoidal groove and the trapezoidal structure of looks adaptation with spacing lug, can reach better joint cooperation effect to accessible inclined plane cooperation promotes each other when moving each other better.

When the sliding member 22 moves from the second position to the first position along the sliding slot 11, that is, from the state shown in fig. 3 to the state shown in fig. 2, the sliding member 22 slides rightward along the sliding slot 11, and when the sliding member 22 slides to a position where the limiting groove corresponds to the limiting projection of the limiting member 21, the elastic member 23 drives the limiting member 21 to rotate relative to the rotating shaft 24 in a direction approaching to the sliding member 22, so that the limiting projection of the limiting member 21 is clamped into the limiting groove of the sliding member 22.

Further, in order to achieve a better and smoother effect when the bracket 10 and the sliding member 22 are switched between locking and unlocking, a first arc-shaped portion which is concave inwards is formed on the periphery side of the bottom wall of the limiting groove, and a second arc-shaped portion which is matched with the first arc-shaped portion is formed on the periphery side, close to one end of the sliding member 22, of the limiting protruding block. The limit groove and the limit lug are matched through the matching of the first arc-shaped part and the second arc-shaped part, and can be matched more smoothly when mutually propped or pushed, so that a better and more smooth effect is achieved.

In some alternative embodiments, the bracket 10 may be provided with at least one mounting hole 14 that may be fixedly engaged with the first outer member by a fastener such as a screw to mount the bracket 10 to the first outer member.
