Thus, the locking portion 267 of the follower 26 is disengaged from the locking groove 14 of the housing 1 by the push top 244. Then, the main body 221 is moved in the direction of the arrow A shown in Fig. 3 until the main body 221 abuts against the mounting portion 12 of the casing 1 and the reset member 28 is stretched and has a tendency to return to its original state. Then, the other end of the first cover 30 is closed on the casing 1 , and the operating portion 242 is loosened. The follower 26 is moved by the restoring force of the reset member 29 in the opposite direction of the arrow A to The locking portion 267 of the movable member 26 is inserted into the locking groove 14 of the housing 10 by the elastic plate 42 and the rib 2632 slides into the locking groove 322 and engages with each other. The other end of the first cover 30 is fixed to the casing 10, and finally the first cover 3 is mounted on the casing 10. When the first cover 30 is opened, the operating portion 242 is first pressed, so that the push top 244 of the unlocking member 24 swings around the boss 224 of the driving member 22 to drive the follower 26 to swing into the housing 10. . Thus, the locking portion 267 of the follower 26 is disengaged from the locking groove 14 of the housing 10 by the pushing top 244, and the rib 2632 on the follower 26 is disengaged from the first cover by the pushing top 244. 3〇 card slot 322. Subsequently, the main body 221 is moved in the direction of the arrow A in Fig. 3 until the main body 221 abuts against the mounting portion 12 of the casing 10, so that the first cover 30 can be removed from one end of the block 32. Then, the other end of the first cover 30 201106834 is removed. In the assembled mobile phone 100, the triggering portion 223 of the button structure 20 is located behind the switch 52 of the main board 5 in its pressing direction (the direction indicated by the arrow B in Fig. 3). The pressing portion 222 is pressed to move the trigger portion 223 connected thereto in the pressing direction and trigger the switch 52 to switch the power of the mobile phone. Therefore, if the user wants to switch the power supply, just press the pressing part μ〗. It can be understood that the function of the rib 2632 and the slot 322 is mainly to make the follower % and the housing ίο more stable. In the preferred embodiment of the present invention, the rib 2632 has a smaller volume. Therefore, when the locking portion 267 has been disengaged from the locking groove 14 and the rib 2632 is not separated from the slot 322, the main body 221 is pushed toward FIG. Moving in the direction of the arrow A, the rib 2632 will slide out of the slot 322 in the aforementioned thrust, so that the latching portion 263 and the latch 32 can be unlocked to open the first cover 30. It can be understood that the main function of the elastic plate 42 is elastically resisted by the follower 26 to stably mount the key structure 20 in the casing 10. Therefore, the position of the elastic plate 42 is not limited to the second cover 4, and the elastic plate π may be disposed on the casing 10 in order to make the structure of the mobile phone more compact. The button structure 20 of the present invention integrates the active component 22 of the mobile phone and the contact member 24 with the cover opening Wei, so that the installation space of the button is saved and the user operation is facilitated.
