In the illustrated structure, the extending portion 215 is further provided with a relief hole 205 through which the operation portion 231 passes, and the relief hole 205 limits the movement limit of the operation portion 231 while the operation portion 231 is being relieved, so that the operation portion 231 is prevented from being deflected sideways to damage the connection block 213, and the effect of protecting the locking member 23 is achieved.

In this embodiment, the elastic member is a spring. The spring is compressed between the carrier 211 and the limiting portion 232, so as to drive the limiting portion 232 downward to be clamped with the base 10. In other embodiments, the elastic member may be a torsion spring or other elastic structure, so long as it can drive the limiting portion 232 to move downward.

In another embodiment of the present application, referring to fig. 5, a plurality of sequentially arranged clamping grooves 103 are formed in the bottom of the accommodating groove 101 of the base 10, and the limiting portion 232 is clamped with the clamping grooves 103 when being located at the first position.

wherein D1 is the furthest distance between the stopper 73 and the second positioning post 72 in the extending direction of the slide rail 30, that is, the distance between the front end point of the stopper 73 and the rear end point of the second positioning post 72 in the front-rear direction. D2 is the farthest distance of the first positioning post 71 and the second positioning post 72 in the extending direction along the slide rail 30, that is, the distance of the front end point of the first positioning post 71 and the rear end point of the second positioning post 72 in the front-rear direction. D3 is the furthest distance between the walls of the first positioning hole 901 and the second positioning hole 902 along the extending direction of the sliding rail 30, and the distance between the foremost end of the first positioning hole 901 and the rearmost end of the second positioning hole 902 along the front-rear direction.

In operation, the first positioning hole 901 is sleeved into the first positioning post 71 and falls below the limiting block 73, and then the second positioning hole 902 is sleeved into the second positioning post 72. Since the stopper 73 is located at the front side of the first positioning post 71, after the first positioning hole 901 is sleeved in the first positioning post 71 and is located at the lower side of the stopper 73, the protective film 90 can be moved backward by a certain range (the diameter of the first positioning hole 901 minus the size range of the first positioning post 71), so that the second positioning hole 902 can reach above the second positioning post 72 and be sleeved in the second positioning post 72. After the second positioning hole 902 is sleeved into the second positioning post 72, the protective film 90 can be assembled without deformation in the positioning assembly process due to D2< D3, so as to avoid the film body from being pulled and deformed to affect the film pasting quality. Since D3< D1, the protective film 90 is entirely limited by the stopper 73 and cannot move upward, thereby guaranteeing the quality of the subsequent film.

The foregoing description of the preferred embodiments of the present application is not intended to be limiting, but is intended to cover any and all modifications, equivalents, or alternatives falling within the spirit and principles of the present application.
