After the protruding end of the switch push block 5 is pressed into the through hole 9 by external force, the other end of the switch push block 5 protrudes out of the through hole 9.

[0030] Operating steps: In the initial state, the left end of the switch push block 5 protrudes from the left side wall of the upper connecting part 3, and the right end of the switch push block 5 is inside the through hole 9. In this state, the switch handle 19 swings to the left, and the toggle switch 20 is in the off state. Push the switch push block 5 to the right, pressing the left end of the switch push block 5 into the through hole 9, so that the right end of the switch push block 5 protrudes from the right side wall of the upper connecting part 3. During this process, the inner groove wall on the left side of the toggle groove 18 pushes the switch handle 19 to swing to the right, so that the toggle switch 20 is turned on. When it is necessary to turn off the toggle switch 20, push the switch push block 5 to the left, pressing the right end of the switch push block 5 into the through hole 9, so that the left end of the switch push block 5 protrudes from the left side wall of the upper connecting part 3. During this process, the inner groove wall on the right side of the toggle groove 18 pushes the switch handle 19 to swing to the left, so that the toggle switch 20 is turned on.

[0031] The inclined left and right inner walls of the toggle groove 18 are respectively used to fit against the surfaces of the switch handle 19 swinging to the right and the switch handle 19 swinging to the left, so that the toggle switch 20 is toggled to the on or off state.

[0032] The upper connecting part 3 is provided with a limiting groove 14, and the switch push block 5 is provided with a limiting block 11 that is placed in the limiting groove 14 and moves. The limiting groove 14 cooperates with the limiting block 11 to limit the extreme position of the switch push block 5 to move to the left or right.

[0033] When the switch push block 5 is pushed to the left, the switch push block 5 moves to the left until the limit block 11 abuts against the groove wall on the left side of the limit groove 14, so as to prevent the switch push block 5 from moving to the left. When the switch push block 5 is pushed to the right, the switch push block 5 moves to the right until the limit block 11 abuts against the groove wall on the right side of the limit groove 14, so as to prevent the switch push block 5 from moving to the right.

[0034] The handle 2 is composed of a left half shell 15 and a right half shell 12. The left half shell 15 and the right half shell 12 are joined together and fixedly connected by screws. Both the left half shell 15 and the right half shell 12 are provided with sliding sleeves 13.
