[0020] In the above structure, the front shell 1 and the rear shell 2 are joined together in a front-to-back manner, and a tight fit can be achieved between them through sealing rings or welding. At the same time, a receiving groove 10 is provided on the side of the front shell 1, and the lower end of the side button 4 can rotate relative to the receiving groove 10, thereby achieving the function of a movable button. Correspondingly, a button switch 50 is provided on the edge of the PCB board 5. The abutment 60 on the conical cap 6 abuts against the button switch 50. When the user presses the side button 4, the conical cap 6 can be deformed to trigger the button switch 50. Because the conical cap 6 covers the through hole 11 and is sandwiched between the bottom of the receiving groove 10 and the side button 4, the through hole 11 remains closed during the triggering of the button switch 50, thus providing stronger waterproof and dustproof capabilities.

[0021] To achieve the movable and flip-up function of the side button 4, in this embodiment, please refer to... Figure 2 The lower end of the receiving groove 10 is formed with a bearing seat 12, and the lower end of the side button 4 is formed with a lower shaft 40.
