A circuit board 6 is also provided in the outer shell 3. An indicator light 9 and a switch assembly 19 are provided on the circuit board 6. Specifically, the indicator light 9 is an LED lamp bead. A resistor 25 connected in series with the indicator light 9 is also provided on the circuit board 6 to achieve a voltage dividing effect, ensure the stability of the indicator light 9 and increase its service life. A wiring hole connecting lead 28 connected to the outside is also provided on the circuit board 6. A light-transmitting upper cover 1 is provided on the outer shell 3. A button 20 is provided on the switch assembly 19. An extrusion surface 21 that can drive the button 20 to move is provided on the lock core 8. The lock core 8 is connected to an elastic reset assembly. Specifically, the elastic reset assembly includes a torsion spring 23. The first leg 24 at one end of the torsion spring 23 is clamped on the lock core 8, and the second leg 22 at the other end is clamped on the lock shell 7. Further, it also includes a mounting sleeve 4. The outer wall of the outer shell 3 is provided with an external thread 5. The mounting sleeve 4 is provided with an internal thread that matches the external thread 5 on the outer shell 3, so as to facilitate the installation of the outer shell 3.
