In summary, as those skilled in the art can easily understand, the embodiment of the present invention provides the limiting portion 34 on the plate 32 of the lid opening button 30, and the interference portion 22 on the button seat 20, when the pressing force acts on the plate 32, the plate 32 moves under the action of the pressing force, under the normal pressing condition, the normal direction of the plate 32 coincides with the axial direction of the assembly hole 12, the plate 32 can move along the axial direction of the assembly hole 12, at this time, the limiting portion 34 and the interference portion 22 do not contact with each other, and the plate 32 can continuously move to the direction close to the housing 10 to open the lid; when the plate body 32 receives the abnormal pressing force, the plate body 32 can be inclined, at this moment, the normal direction of the plate body 32 is turned over by a certain angle compared with the axis direction of the assembling hole 12, when the angle is larger than the preset angle, the limiting part 34 can be abutted against the interference part 22, and then the plate body 32 is limited to further move towards the direction close to the shell 10, so as to prevent the cover opening process of the cover opening button 30 from generating the phenomenon of blocking. In addition, in the present embodiment, the button seat 20 and the housing 10 are integrally formed, so that on one hand, the assembly process of the button seat 20 and the housing 10 can be reduced, and the assembly efficiency can be improved; on the other hand, the assembling error of the button holder 20 and the housing 10 can be reduced, thereby improving the assembling precision of the lid opening button 30.

The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes of the present invention are used in the specification and the attached drawings, or directly or indirectly applied to other related technical fields, and the same principle is included in the protection scope of the present invention.
