Under the cooperation between the circuit breaker body 1, the slot 13, the fixed column 21, the slide groove 23, the slider 25 and the push block 24, when the slider 25 moves, it can drive the push block 24 to slide in the slide groove 23 and the slot 13.

[0027] The inner side surfaces of the reserved holes 12 are provided with fixed grooves 14, and a movable block 16 is slidably connected in the fixed grooves 14. An inclined groove 161 is provided on the surface of the movable block 16. The side walls of the pushing block 24 contact the inclined groove 161 when moving. With the cooperation among the reserved holes 12, the fixed grooves 14, the movable block 16, the inclined grooves 161 and the pushing block 24, the movable block 16 is initially in the fixed grooves 14.

[0028] A spring 162 is fixedly installed on the inner wall of the movable block 16, and the other end of the spring 162 contacts the inner wall of the reserved hole 12. The movable block 16 can be slidably connected in the reserved hole 12. Under the cooperation between the movable block 16, the spring 162 and the reserved hole 12, the movable block 16 can slide in the reserved hole 12 after being pushed out by the pushing block 24.

[0029] A fixing ring 27 is fixedly installed on the surface of the fixing column 21, and the connecting rod 26 is slidably connected in the fixing ring 27. A spring 28 is fixedly installed between the side wall of the slider 25 and the side wall of the chamber 22. With the cooperation between the fixing column 21, the fixing ring 27, the connecting rod 26, the slider 25, the chamber 22 and the spring 28, the spring 28 can pull the slider 25 to the fixed side in a natural state.

[0030] The sides of the slider 25 are provided with mounting grooves 251, and the clamping assembly 3 includes a clamping block 31 slidably connected in the mounting groove 251, and a spring three 32 is fixedly installed between the side wall of the clamping block 31 and the side wall of the mounting groove 251. Under the cooperation between the slider 25, the mounting groove 251, the clamping block 31 and the spring three 32, when the slider 25 moves to the mounting groove 251 facing the clamping groove 15, the spring three 32 can automatically push the clamping block 31 outward and clamp it in the clamping groove 15.

[0031] A slot 15 is provided on the side of the circuit breaker body 1, and a connecting block 17 is slidably connected in the slot 15. The block 31 can be slidably connected in the slot 15. With the cooperation between the circuit breaker body 1, the slot 15, the connecting block 17 and the block 31, the limiting effect of the block 31 on the slider 25 can be cancelled by pushing the connecting block 17.

[0032] When wiring is needed, the wiring terminal can be inserted into the wiring hole 11, and the connecting rod 26 can be pushed into the chamber 22. At this time, the connecting rod 26 drives the slider 25 to slide along the inner wall of the chamber 22. When the slider 25 moves, it drives the side pushing block 24 to slide along the slot 13 and the slide slot 23. When the pushing block 24 moves downward, it contacts the movable block 16 in the fixed slot 14 at the lower end. The lower end of the pushing block 24 slides into the inclined slot 161, and the movable block 16 is squeezed outward along the fixed slot 14 until the movable block 16 is pushed into the reserved hole 12. At this time, under the action of the spring 162, the movable block 16 is automatically pushed out and slides into the reserved hole 12, and the slider 25 is pushed to the installation on its side. When the slot 251 is directly opposite to the card slot 15, the spring three 32 can automatically push the card block 31 outward until it is stuck in the card slot 15 to complete the fixation of the slider 25. The fixation of the connecting terminal can be completed by the cooperation between the stop block 29 and the movable block 16. When the connecting line needs to be replaced, the connecting block 17 is pushed into the card slot 15 to push the card block 31 into the installation slot 251. At this time, the slider 25 can be automatically pulled back by the spring two 28, and the connecting line can be removed for replacement. When the device is wiring, when the connecting rod 26 is pushed, the stop block 29 and the movable block 16 can be driven to clamp the connecting line at the same time. When the line needs to be changed, the connecting block 17 is pushed into the card slot 15 to cancel the clamping of the connecting line.
