[0029] When the rotating disc 201 rotates, the fixing piece 202 is moved, the fixing piece 202 drives the moving piece 204 to move through the connecting piece 203, so that the moving piece 204 separates the circuit breaker body 102 to avoid air discharge. When the rotating disc 201 rotates counterclockwise, the fixing piece 202 moves, the fixing piece 202 pulls the connecting piece 203 to move, and the connecting piece 203 pulls the moving piece 204 to move away from the arc discharge area, so that the circuit breaker body 102 can normally work.

[0030] Embodiment 2

[0031] Reference Figures 1-3 This is the second embodiment of the utility model, which is based on the previous embodiment.

[0032] Specifically, the fixing piece 202 comprises a first sliding rail 202c, a second sliding rail 202d, a first fixed rod 202a and a second fixed rod 202b. One side of the first sliding rail 202c is fixed to the inner side wall of the circuit breaker body 102. One side of the second sliding rail 202d is slidingly connected to the inside of the first sliding rail 202c. The first fixed rod 202a is fixed to the side of the second sliding rail 202d. The second fixed rod 202b is rotationally arranged at the end of the first fixed rod 202a.

[0033] The second sliding rail 202d is protruded on one side and located in the first sliding rail 202c. The second sliding rail 202d is slid in the first sliding rail 202c. One side of the rotating disc 201 is fixed with a connecting column. The other end of the connecting column is located in the first sliding groove S on the second sliding rail 202d. When the rotating disc 201 rotates, the connecting column rotates and pushes the second sliding rail 202d to move in the first sliding groove S on the second sliding rail 202d. The second sliding rail 202d drives the first fixed rod 202a to move. The first fixed rod 202a drives the second fixed rod 202b to move. The second fixed rod 202b drives the connecting piece 203 to move. The connecting piece 203 drives the moving piece 204 to move, so as to separate the inside of the circuit breaker body 102, thereby preventing air discharge.

[0034] Specifically, the first sliding rail 202c and the second sliding rail 202d are both provided with a first sliding groove S.

[0035] The second sliding rail 202d slides in the sliding groove S of the first sliding rail 202c.

[0036] Specifically, the second sliding rail 202d is slidingly connected to one side of the rotating disc 201.

[0037] The rotating disc 201 rotates and slides in the sliding groove S of the second sliding rail 202d.

[0038] Specifically, the connecting piece 203 comprises a first connecting rod 203a, a connecting frame 203b and a second connecting rod 203d, the first connecting rod 203a is fixed to the bottom of the second fixed rod 202b, the connecting frame 203b is rotatably connected to the top of the first connecting rod 203a, and the second connecting rod 203d is rotatably connected to the top of the connecting frame 203b.

[0039] When the second fixed rod 202b moves, the first connecting rod 203a is driven to move, the connecting frame 203b is pulled to rotate through the first connecting rod 203a, the second connecting rod 203d is driven to move through the connecting frame 203b, the moving piece 204 is driven to move through the second connecting rod 203d, and the space inside the circuit breaker body 102 is separated.

[0040] Specifically, the connecting piece 203 further comprises a fixed column 203c, the fixed column 203c is fixed to the inner bottom wall of the circuit breaker body 102, and the top of the fixed column 203c is rotatably connected to the connecting frame 203b.

[0041] The fixed column 203c is used for supporting the connecting frame 203b, so that the connecting frame 203b remains stable.

[0042] Embodiment 3

[0043] Referring to Figures 1-3 As a third embodiment of the utility model, the embodiment is based on the previous two embodiments.

[0044] Specifically, the connecting frame 203b is L-shaped, and the included angle thereof is ninety degrees.

[0045] For facilitating driving the second connecting rod 203d when rotating.

[0046] Specifically, the moving piece 204 comprises a moving plate 204a and a moving rod 204c, one side of the moving plate 204a is fixed to one end of the second connecting rod 203d, and one end of the moving rod 204c is rotatably connected to the circuit breaker body 102.

[0047] The second connecting rod 203d moves to drive the moving plate 204a to slide on the moving rod 204c, and the moving plate 204a is limited by the moving rod 204c to keep stable during movement. The moving plate 204a separates the discharge elements inside the circuit breaker body 102 during movement, thereby avoiding air discharge of the internal electrical elements of the circuit breaker body 102 during power-off, which causes the circuit breaker body 102 to malfunction.

[0048] Specifically, the moving plate 204a is provided with a second sliding groove H on the surface, and the moving rod 204c is slidingly connected in the sliding groove S.

[0049] The second sliding groove H is provided to enable the moving plate 204a to stably slide on the surface of the moving rod 204c.

[0050] In use, when the circuit breaker body 102 is cut off, the second sliding rail 202d of the operating rod 103 is pushed downward to be convex on one side and located in the first sliding rail 202c. The second sliding rail 202d is made to slide in the first sliding rail 202c. The connecting column is fixed on one side of the rotating disc 201 and located in the first sliding groove S on the second sliding rail 202d. The connecting column is rotated to push the second sliding rail 202d to move in the first sliding groove S on the second sliding rail 202d. The second sliding rail 202d drives the first fixed rod 202a to move, and the first fixed rod 202a drives the second fixed rod 202b to move. The second fixed rod 202b drives the first connecting rod 203a to move during movement. The first connecting rod 203a pulls the connecting frame 203b to rotate, and the connecting frame 203b drives the second connecting rod 203d to move. The second connecting rod 203d moves to drive the moving plate 204a to slide on the moving rod 204c. The moving plate 204a is limited by the moving rod 204c to keep stable during movement. The moving plate 204a separates the discharge elements inside the circuit breaker body 102 during movement, thereby avoiding air discharge of the internal electrical elements of the circuit breaker body 102 during power-off, which causes the circuit breaker body 102 to malfunction.

[0051] The operating rod 103 is pushed upward to rotate the rotating disc 201 counterclockwise to drive the second sliding rail 202d to slide in the first sliding groove S, so that the first fixed rod 202a and the second fixed rod 202b pull the first connecting rod 203a to move. At this time, the connecting frame 203b rotates clockwise on the top of the fixed column 203c to drive the second connecting rod 203d to move. The moving plate 204a slides on the surface of the moving rod 204c away from the arc discharge area.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, and they should be covered in the scope of the claims of the present application.
