[0022] The wall thickness of the arc rod 21 is 5 mm-8 mm.

[0023] Working principle: After the electrical equipment is installed, the device is used to replace the traditional switch for connection and use. When the electrical equipment needs to be activated, the staff holds the first barrel body 3 and rotates the first barrel body 3. The first barrel body 3 drives the first L-shaped rod 4 to slide in the first arc groove 1-1, and the first L-shaped rod 4 drives the sleeve 8 to rotate. The sleeve 8 drives the T-shaped rotating rod 9 to rotate. The T-shaped rotating rod 9 rotates to tighten the spring 11. The first L-shaped rod 4 drives the slider 7 to slide in the second arc groove 6-1. The first L-shaped rod 4 slides from one side of the first arc groove 1-1 to the other side and then stops moving. When the first L-shaped rod 4 stops sliding, the slider 7 is just opposite to the through hole 6-2. Then the staff presses the first barrel body 3, and the switch 2 is closed, so that the electrical equipment starts to work. , the first barrel body 3 drives the first L-shaped rod 4 to move, the first L-shaped rod 4 drives the second groove 4-1 to move, the first L-shaped rod 4 drives the slider 7 to move and gradually slide out of the through hole 6-2, the slider 7 gradually moves to push the T-shaped slide bar 19 to slide and squeeze the second return spring 20, the first barrel body 3 squeezes the switch 2, so that when the switch 2 is closed, at this time, one end of the cross bar of the T-shaped slide bar 19 is just inserted into the second groove 4-1, because the cross section of one end of the cross bar of the T-shaped slide bar 19 is an inclined surface, thereby realizing the limiting effect on the first L-shaped rod 4, and only making the first L-shaped rod 4 move in one direction, after the switch 2 is closed, the first L-shaped rod 4 can no longer be pushed, the first L-shaped rod 4 cannot move, so that the first barrel body 3 cannot continue to be pressed, thereby ensuring the closed state of the switch 2, preventing the switch from being opened. In case switch 2 is accidentally hit, after the electrical equipment is used, it is necessary to stop the electrical equipment from working. The staff first presses the ring 12, and the ring 12 drives the second L-shaped rod 13 to move, and the second L-shaped rod 13 drives the threaded sleeve 16 to move and squeeze the first return spring 17, and the threaded sleeve 16 drives the threaded rod 15 to rotate, and the threaded rod 15 drives the arc rod 21 to rotate, and the arc rod 21 rotates to push the T-shaped slide bar 19 to move and squeeze the second return spring 20, and the T-shaped slide bar 19 moves and gradually slides out of the second groove 4-1 to cancel the limit on the first L-shaped rod 4, and then the staff presses the first barrel body 3, and the first barrel body 3 drives the first L-shaped rod 4 to move, and the turned-on switch 2 pushes the first barrel body 3 to move, and the first barrel body 3 drives the first L-shaped rod 4 to move, and the first L-shaped rod 4 drives the slider 7 to move, the slider 7 moves to push the T-shaped slide bar 19 to move and squeeze the second reset spring 20. When the switch 2 is reset and stationary, the slider 7 just slides into the second arc groove 6-1. At this time, the deformed clockwork 11 drives the T-shaped rotating rod 9 to rotate, the T-shaped rotating rod 9 drives the sleeve 8 to rotate, the sleeve 8 drives the first L-shaped rod 4 to slide in the first arc groove 1-1 for reset, the first L-shaped rod 4 drives the slider 7 to slide gradually into the second arc groove 6-1, the first L-shaped rod 4 drives the first barrel 3 to rotate, and then the ring 12 is released. At this time, the squeezed first reset spring 17 pushes the threaded sleeve 16 to move for reset, the threaded sleeve 16 drives the threaded rod 15 to rotate, and the threaded rod 15 drives the arc rod 21 to rotate for reset.The arc rod 21 rotates and gradually separates from the T-shaped slide bar 19. At this time, the squeezed second reset spring 20 pushes the T-shaped slide bar 19 to move and reset. The third barrel body 6 limits the slider 7, so that the slider 7 cannot move. The slider 7 cannot move, so that the first L-shaped rod 4 cannot move. The first L-shaped rod 4 cannot move, so that the first barrel body 3 cannot move, thereby ensuring the open state of the switch 2, preventing the switch 2 from being accidentally hit, and ensuring the normal operation of the electrical equipment. The setting of the spring 11 and multiple first reset springs 17 and the second reset spring 20 plays an effective reset role to ensure the normal operation of the device.
