The first fixing hole 1711 is internally provided with a nut 40 and a screw 30 connected with the nut 40 in a matching manner, and the plunger 14 penetrates through the first fixing hole 1711 and the second fixing hole 1712 through a through hole 31 arranged in the screw 30, and extends out through the second fixing hole 1712 to abut against the rod body 131 of the driving rod 13, so as to drive the driving rod 13 to move. Alternatively, the nut 40 is fixedly disposed in the first fixing hole 1711 by heat fusion.

Specifically, the fixing holes 171 are provided at positions corresponding to the positions of the coupling holes 21 on the rear case 20 such that the screws 30 correspond to the assembly positions of the nuts 40.

Further, in order to improve the overall waterproof performance of the mobile terminal and prevent external liquid from flowing into the mobile terminal through the through hole 31 or the fixing hole 171 in the screw 30, the waterproof rubber ring 16 is disposed in the first fixing hole 1711, specifically, on the step end face formed between the first fixing hole 1711 and the second fixing hole 1712, the waterproof rubber ring 16 is pressed by the nut 40 disposed in the first fixing hole 1711, so as to stabilize the assembly of the waterproof rubber ring 16 in the first fixing hole 1711.
