In this embodiment, the fixing section 2221 is tightly fitted to the fixing hole 231, so that the elastic structure 22 is prevented from moving relative to the button 23. The maximum diameter of the limit section 2222 is larger than the aperture of the fixing hole 231 near one end of the limit section 2222, so that when the limit section 2222 passes through the fixing hole 231 through extrusion, elastic deformation can be recovered and the limit section can be abutted against one side of the button 23, which is far away from the main body 221, so that the elastic structure 22 can be limited to move back along the axial direction of the fixing hole 231, and the elastic structure 22 and the button 23 can be prevented from being separated. The guiding section 2223 plays a role in guiding and limiting the spring 24, so that the spring 24 is guided to stretch along the axial direction of the guiding section 2223, and the spring 24 is prevented from deviating.
