By setting a slidable rotating drum 8, when there is no need to manually rotate the rotating rod 3, the second magnet 11 and the first magnet 6 can be adsorbed to avoid the engagement of the positioning block 7 with the clamping groove 10. Even if the rotating drum 8 rotates, the rotating rod 3 will not be rotated, thereby avoiding misoperation and enhancing safety.

[0022] A pull ring 12 is installed on the top of the rotating drum 8, and two sliders 13 are slidably connected inside the rotating drum 8. Slide rods 15 are fixedly connected to the surfaces of the two sliders 13. The end of the slide rod 15 away from the slide rod 13 is arc-shaped. A spring 14 is movably installed between the two slides 13. A connecting block 16 is fixedly connected to the bottom of the pull ring 12. The end of the connecting block 16 away from the pull ring 12 is clamped in the interior of the positioning groove 19. A positioning ring 18 is fixedly sleeved on the outer surface of the connecting block 16. An elastic ring 17 is fixedly connected to the surface of the positioning ring 18. The outer surface of the positioning ring 18 is slidably connected to the interior of the rotating drum 8. The elastic ring 17 is a silicone ring. Under normal circumstances, the positioning ring 18 drives the connecting block 16 to slide downward through the elasticity of the silicone ring. A positioning groove 19 is opened on the surface of the slide rod 15. By providing the pull ring 12, the rotating drum 8 can be easily pulled out from the rotating groove 2. By providing a slidable slide rod 15, when the slide rod 15 pops out, the cross formed by the slide rod 15 and the rotating drum 8 can be easily rotated, thereby enhancing practicality.

[0023] When it is necessary to manually turn the switch, the pull ring 12 drives the rotating drum 8 to slide to the outside of the rotating groove 2, and the positioning block 7 slides inside the rotating groove 9. When it slides to the position of the card slot 10, the positioning block 7 is engaged with the card slot 10. At this time, the pull ring 12 is continued to be pulled, and the pull ring 12 drives the connecting block 16 to slide upward. When the connecting block 16 is disengaged from the inside of the positioning groove 19, the elasticity of the spring 14 is used to make the slider 13 drive the slide bar 15 to slide and pop out the slide bar 15, and then the slide bar 15 and the rotating drum 8 are held to rotate the rotating drum 8. When the rotating drum 8 rotates, the positioning block 7 drives the rotating rod 3 to rotate to realize manual rotation of the switch. When there is no need to manually rotate the rotating rod 3, the second magnet 11 and the first magnet 6 are adsorbed to avoid the engagement of the positioning block 7 with the card slot 10. Even if the rotating drum 8 rotates, the rotating rod 3 will not be rotated, thereby avoiding misoperation and enhancing safety.
