Wherein the second end 1132 of the third runner 113 and the second end 1142 of the fourth runner 114 are located between the first runner 111 and the second runner 112 such that the drive runner forms a "Y" like shape. The fastening wall 1143 is disposed on the fourth chute 114, and the fastening wall 1143 faces the same direction as the first direction; the second end of the elastic locking assembly 400 is slidably abutted against the bottom of the first chute 111, the bottom of the third chute 113, the bottom of the fourth chute 114, and the bottom of the second chute 112 under the action of the elastic force of the elastic locking assembly 400, and the second end of the elastic locking assembly 400 is movably abutted against the fastening wall 1143. In this embodiment, the first chute 111, the third chute 113, the fourth chute 114 and the second chute 112 are sequentially connected end to form a closed driving chute 1101.
In this embodiment, the elastic locking member 400 is supported by the base 100 and keeps abutting against the bottoms of the first sliding groove 111, the third sliding groove 113, the fourth sliding groove 114 and the second sliding groove 112, and the elastic locking member 400 can only move relative to the sliding member 100 according to the paths from the first sliding groove 111, the third sliding groove 113, the fourth sliding groove 114 and the second sliding groove 112 to the first sliding groove 111 in sequence due to the arrangement of the first step, the second step, the third step and the fourth step. The first step, the second step, the third step and the fourth step serve as a stop for the elastic locking assembly 400, so that when the elastic locking assembly 400 slides relative to the sliding member 100, the elastic locking assembly can only move along the path from the first sliding groove 111, the third sliding groove 113, the fourth sliding groove 114, the second sliding groove 112 to the first sliding groove 111, that is, can only move relative to the sliding member 100 from the second end 1112 of the first sliding groove 111 to the first end 1111 of the first sliding groove 111, from the first end 1131 of the third sliding groove 113 to the second end 1132 of the third sliding groove 113, from the second end 1142 of the fourth sliding groove 114 to the first end 1141 of the fourth sliding groove 114, and from the first end 1121 of the second sliding groove 112 to the second end 1122 of the second sliding groove 112. In the present embodiment, the directions from the second end 1112 of the first chute 111 to the first end 1111 of the first chute 111, and the second end 1142 of the fourth chute 114 to the first end 1141 of the fourth chute 114 are substantially the same as the first direction, and the directions from the first end 1131 of the third chute 113 to the second end 1132 of the third chute 113, and the directions from the first end 1121 of the second chute 112 to the second end 1122 of the second chute 112 are the same as the second direction.
In the present embodiment, the second end 1132 of the third sliding slot 113 and the second end 1142 of the fourth sliding slot 114 are located between the first sliding slot 111 and the second sliding slot 112, that is, the buckling wall 1143 is located between the first sliding slot 111 and the second sliding slot 112, and the buckling wall 1143 is oriented in the same direction as the first direction, so that the sliding member 100 moves under the external force opposite to the first direction, and the elastic locking assembly 400 moves from the initial end of the driving sliding slot 1101 to the third sliding slot 113 along the first direction relative to the sliding member 100, and moves from the first sliding slot 111 to the third sliding slot 113; the sliding member 100 moves under the elastic force of the first elastic member 300, so that the elastic locking assembly 400 moves along the second direction relative to the sliding member 100, and moves from the third sliding slot 113 to the fourth sliding slot 114 and abuts against the buckling wall 1143, so that the elastic locking assembly 400 is locked with the sliding member 100; continuing to move the slider 100 from the position abutting the catch wall 1143 under the force of the external force opposite the first direction thereafter moves the resilient locking assembly 400 in the first direction relative to the slider 100 from the fourth runner 114 to the second runner 112; then, the sliding member 100 moves under the elastic force of the first elastic member 300, so that the elastic locking assembly 400 moves to the starting end of the driving chute 1101 along the second direction relative to the sliding member 100, and the elastic locking assembly 400 is unlocked from the sliding member 100. Thus, the elastic locking assembly 400 and the sliding member 100 can be unlocked or unlocked by only applying an external force to the sliding member 100 opposite to the first direction to control the movement of the sliding member 100. It should be noted that, the movement of the elastic locking assembly 400 referred to herein is actually movement relative to the sliding member 100 under the movement of the sliding member 100, and the elastic locking assembly 400 does not move, so that the elastic locking assembly 400 moves in the driving chute 1101 due to the relative movement between the sliding member 100 and the elastic locking assembly 400.
It should be noted that, when the elastic locking assembly 400 abuts against the fastening wall 1143, the elastic locking assembly 400 abuts against the sliding member 100, and since the elastic locking assembly 400 is fixedly connected with the base 200, the sliding of the sliding member 100 on the base 200 is limited by the elastic locking assembly 400, the sliding member 100 cannot slide even if the elastic force of the first elastic member 300 acts on the sliding member, so as to lock the locking device. When unlocking is required, the sliding member 100 is pushed to slide on the base 200, so that the elastic locking assembly 400 is separated from the buckling wall 1143 and moves to the starting end of the driving chute 1101, and unlocking can be achieved.
To guide the sliding movement of the resilient locking assembly 400 along the fourth chute 114 to the second chute 112, in one embodiment, as shown in fig. 5, the fourth chute 114 is provided with a first guiding wall 1144, the first guiding wall 1144 is disposed opposite to the fastening wall 1143, and the first guiding wall 1144 gradually slopes from the second end 1142 of the fourth chute 114 to the first end 1141 of the fourth chute 114 in a direction away from the fastening wall 1143, such that, when the resilient locking assembly 400 slides in the fourth chute 114, the first guiding wall 1144 can generate a component force on the resilient locking assembly 400 away from the fastening wall 1143, thereby pushing the resilient locking assembly 400 to slide toward the second chute 112.
To guide the resilient locking assembly 400 to slide from the first end 1131 of the third runner 113 to the snap wall 1143 during locking, in one embodiment, as shown in fig. 5, the third runner 113 is provided with a second guide wall 1134, and the second guide wall 1134 gradually slopes from the first end 1131 of the third runner 113 to the second end 1132 of the third runner 113 toward a direction approaching the snap wall 1143, such that when the resilient locking assembly 400 slides within the third runner 113, the second guide wall 1134 will generate a component force toward the snap wall 1143, such that the resilient locking assembly 400 slides along the second guide wall 1134 to abut against the snap wall 1143, thereby achieving locking.
To further improve stability of the resilient locking assembly 400 and slider 100 when locked, in one embodiment, the snap walls 1143 are recessed. Specifically, the fastening wall 1143 is concavely disposed in the second direction, so that a limiting space is formed at a concave position of the fastening wall 1143, and compared to the fastening wall 1143 disposed in a plane, the elastic locking assembly 400 is limited in the limiting space when being abutted against the fastening wall 1143, thereby further improving the stability of the elastic locking assembly 400 and the sliding member 100 when being locked. In this embodiment, to further prevent the movement of the elastic locking assembly 400 when the elastic locking assembly 400 is locked with the slider 100, in one embodiment, the snap wall 1143 has a circular arc-shaped cross section. By providing the recessed snap walls 1143 with a circular arc shaped cross section, the resilient locking assembly 400 is further prevented from moving when the resilient locking assembly 400 is locked with the slider 100.
