One of the front middle frame 10 and the slide cover 20 is provided with a sink 900. Specifically, the sink 900 is opened in the front middle frame 10. The supporting member 60 is partially received in the sinking groove 900 and is in clearance fit with the wall of the sinking groove 900. Since the direction of the force pressing the slide cover 20 is uncertain, the above arrangement allows the support 60 to have a greater degree of freedom to accommodate the lateral pressure from the slide cover 20 in different directions. Meanwhile, the greater degree of freedom can prevent the support 60 from rigidly abutting the slide cover 20, and the arrangement can prevent the slide cover 20 from being scratched because the duration of side pressing of the slide cover 20 is short.

In one embodiment, referring to fig. 1-4, 7, 9, 12, 13, and 15 together, front center 10 includes a fixed portion 11 and a suspended portion 12. The fixing portion 11 is connected with the door body. The suspension portion 12 is bent away from the door body from the fixing portion 11 to form a handle structure. So make the tool to lock still have the handle function when having the locking door body to conveniently drive the door body. Further, the shape of the slide cover 20 matches the shape of the overlapping area of the slide cover 20 and the front middle frame 10.

All possible combinations of the technical features of the above embodiments may not be described for the sake of brevity, but should be considered as within the scope of the present disclosure as long as there is no contradiction between the combinations of the technical features.

The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the invention, which is defined by the appended claims.
