Specifically, two convex blocks are arranged on the stop block 6, are positioned between the two first guide rib plates 108 and are respectively attached to the two guide rib plates, and therefore sliding fit is achieved. The stopper 6 is in a follow-up state together with the second elastic member 7 on the lower cover 102 before being in contact with the first slider 2, one section of the second elastic member 7 may be coupled to a bar-shaped boss formed on the lower cover 102, and the other end may be coupled to a square groove formed on the stopper 6, at which time the spring is in a natural state. The first slide block 2 will be attached to the locking block 302 during the sliding process, and before the locking state is reached, the first slide block 2 is already in contact with the stop 6, so as to generate the pushing force in the advancing direction, and the second elastic element 7 is changed into the deformation state from the natural state.

On one hand, the first sliding groove 103 can play a guiding role, on the other hand, the first sliding groove 103 enables the object to be connected and the first sliding block 2 to be connected in the vertical direction, and the second sliding block 5 penetrates through the shell 1, so that the space structure of a product is optimized.

In some embodiments, as shown in fig. 5 and 12, the unlocking assembly 4 of the connection mechanism 100 includes a pressing piece 401 slidably disposed in the housing 1, and the pressing piece 401 may push the locking piece 302 and separate the locking piece 302 from the position-limiting portion 201 during the sliding process. Wherein, the theory of operation that briquetting 401 promoted locking block 302 is the same with the theory of operation that first section 202 of first slider 2 promoted locking block 302, one end at briquetting 401 and locking block 302 butt is formed with third spigot surface 402, third spigot surface 402 is preferred the arcwall face as shown in the figure, the setting of third spigot surface 402 can make at the gliding in-process of briquetting 401, after contacting with locking block 302, can be smooth outwards promote locking block 302, avoid blocking and reducing wear between the structure, briquetting 401 constantly promotes locking block 302, until locking block 302 breaks away from with spacing portion 201 on the first slider 2, first slider 2 can follow the opening part roll-off along the slide like this, realize the separation of first slider 2 and casing 1. Under the condition that the locking block 302 is provided with the first guide surface 303, after the arc-shaped surface of the pressing block 401 abuts against the guide inclined surface of the locking block 302, the two are in tangential sliding fit, and the friction resistance in the sliding process is reduced. Specifically, in order to further limit the sliding direction of the press block 401, a third guiding rib plate 110 may be provided on the lower cover 102 of the housing 1, as shown in fig. 5, 10, 12 and 13, two parallel third guiding rib plates 110 are provided on both sides of the press block 401, and the press block 401 is limited to slide between the two parallel third guiding rib plates 110.
