[0030] In some optional embodiments, the push twist assembly comprises a strip-shaped matching part and a limiting part; the matching part is arranged in the fixed shell; the limiting part is arranged outside the fixed shell and connected with the matching part; a displacement groove is arranged on the matching part, and a first inclined surface is arranged on one side of the displacement groove away from the limiting part; the first inclined surface is inclined towards the limiting part; the button assembly comprises a pressing part and a displacement part vertically connected with the pressing part; the displacement part is movably arranged in the displacement groove, and a second inclined surface is arranged on the displacement part and matched with the first inclined surface.

[0031] From the above description, the push twist assembly is provided with a limiting part for limiting external equipment, and the matching part is connected with the limiting part, and cooperation between the displacement part of the button assembly and the first and second inclined surfaces is realized, so that the first inclined surface pushes the second inclined surface to move backward after the pressing part is pressed, that is, the first inclined surface moves in the vertical direction while driving the second inclined surface to move in the horizontal direction, so that the matching part drives the limiting part to move backward, realizing limiting release.

[0032] Further, the limiting part is L-shaped; a first end of the limiting part is parallel to the top surface of the fixed shell and extends outward away from the fixed shell; a second end of the limiting part is perpendicular to the top surface of the fixed shell and connected with the first end of the matching part.

[0045] As can be known from the above description, by arranging the left sliding groove and the right sliding groove in the horizontal direction in the fixed shell, the movement of the push-torque assembly is limited, and meanwhile the button assembly and the push-torque assembly can be transmissionally connected in the area separated by the left sliding groove and the right sliding groove.

[0046] The specific working principle of the self-locking button is as follows:

[0047] In the initial state, the elastic member supports the button assembly, the elastic reset member supports the push-torque assembly, and the second inclined surface in the button assembly and the first inclined surface in the push-torque assembly support each other, so that the limiting part of the push-torque assembly is stretched to limit the movement.

[0048] a. When the limiting is released, the elastic member is compressed by pressing the pressing part, so that the button assembly as a whole moves downward; in the process of moving downward, the first inclined surface moves downward in the vertical direction, thereby driving the second inclined surface to move backward in the horizontal direction, so that the push-torque assembly as a whole moves backward and compresses the elastic reset member, so that the limiting part is retracted to release the limiting. After the external force is removed, the push-torque assembly and the button assembly are reset under the action of the elastic reset member and the elastic member, so that the limiting part of the push-torque assembly is stretched to complete self-locking.

[0049] b. When the limiting is released, the limiting part is pushed backward, so that the push-torque assembly as a whole moves backward under the action of the pushing force and compresses the elastic reset member, so that the limiting is released.
