Specifically, when the case cover 4 is covered on the case 3, the protruding points 215 are inserted into the hole structures 221, and the hole structures 221 limit the movement of the protruding points 215 in the plane direction, so as to limit the position of the case cover 4 in any direction in the plane direction, thereby increasing the stability of the cooperation of the case cover 4 and the case 3 when the case cover 4 is covered on the case 3, and simultaneously preventing the hanging nails 11 from sliding into the guide portions 1211 due to the inclination or shaking of the case, so as to affect the stability of the cooperation of the case cover 4 and the case 3.

It should be noted that, the positioning component 22 may be fixedly connected with the case 3 or the case cover 4 in an integrally formed manner, that is, the positioning component 22 may be considered to be a part of the case 3 or the case cover 4, the hole structure 221 on the positioning component 22 may penetrate through the case 3 or the case cover 4 along the direction in which the protruding point 215 is inserted into the hole structure 221, that is, the hole structure 221 may be a through hole; meanwhile, the hole structure 221 may be a blind hole recessed along the direction in which the bump 215 is inserted into the hole structure 221; the positioning member 22 may be a plate-like structure, and may be fixed to the case 3 or the case lid 4 by welding, caulking, or bonding, or the like, and the hole structure 221 may be penetrated or not penetrated in the direction in which the bump 215 is inserted into the hole structure 221. In addition, when the cover 4 is covered on the case 3, the peg 11 is inserted into the engagement portion 1212 in a direction perpendicular to the plane. The plane direction includes all directions on a plane perpendicular to the direction in which the bump 215 is inserted into the hole structure 221, and includes the direction of opening the cover. In addition, the elastic mounting member 21 has a sheet-like structure having elasticity, and the elastic mounting member 21 can elastically deform itself by an external force so that the protruding points 215 are separated from the hole structures 221. In the present embodiment, the plane direction includes all directions on a plane perpendicular to the left-right direction.

Specifically, the elastic mounting member 21 includes: the elastic piece 211 and the reinforcing piece 212 are installed. The mounting spring piece 211 includes: the protruding elastic portion 2111 and the flat mounting portion 2112. Wherein the number of the flat mounting portions 2112 is at least one. In the present embodiment, the number of the plane mounting portions 2112 is two. The two plane mounting portions 2112 are located at opposite ends of the protruding elastic portion 2111, respectively, and the two plane mounting portions 2112 are located on the same plane. The middle portion of the protruding elastic portion 2111 protrudes outward, and the protruding point 215 is provided on the middle portion of the protruding elastic portion 2111. One end of the flat mounting portion 2112 is fixedly connected to an edge of the protruding elastic portion 2111, and the two flat mounting portions 2112 are located on opposite sides of the protruding elastic portion 2111. Each of the planar mounting portions 2112 is provided with a first mounting hole 213. The flat mounting portion 2112 is for fixing to the case 3 or the cover 4 by the engagement of the first mounting hole 213 with a screw. The protruding elastic portion 2111 is used to press the bump 215 into the hole structure 221 so that the bump 215 is mated with the hole structure 221.

The outer surface of the bump 215 or the outer surface of the portion of the bump 215 inserted into the hole structure 221 is curved. When the protruding point 215 and the hole structure 221 are required to be separated from each other, by moving the relative positions of the elastic mounting member 21 and the positioning member 22 along the plane direction, the protruding point 215 can be compressed and deformed in the direction of the plane mounting portion 2112 by the protruding elastic portion 2111 under the guiding action of the curved surface, so that the protruding point 215 and the hole structure 221 are separated from each other.

In addition, the reinforcing piece 212 is perpendicular to the planar mounting portion 2112. In this embodiment, the reinforcing sheet 212 is fixedly connected to the two planar mounting portions 2112 by integrally forming, and two second mounting holes 214 are formed in the reinforcing sheet 212. The provision of the reinforcing sheet 212 enables the elastic mounting member 21 to be adapted to more applications. In particular, in an application scenario in which the planar mounting portion 2112 and the reinforcing piece 212 can be fixed at the same time, the reinforcing piece 212 can elastically mount the stability of the mounting of the member 21.
