The circuit breaker body 1 is taken and mounted on the top of the mounting seat 5. Then, when the through holes 4 on the L-shaped plate 3 meet the fixing mechanism, the fixing mechanism is used to limit and fix the L-shaped plate 3, thereby limiting and fixing the entire circuit breaker body 1.

[0029] Specifically, refer to Figure 4 and Figure 5The fixing mechanism includes a plurality of springs 8, one end of the spring 8 is fixedly installed with the inner wall of the placement groove 6, and the other end of the spring 8 is fixedly connected with a fixing column 9. The number of the fixing columns 9 is consistent with the number of the springs 8. Each fixing column 9 is respectively adapted to the corresponding through hole 4. The side wall of each fixing column 9 is fixedly connected with a connecting plate 10. A plurality of rectangular grooves 7 are provided inside the mounting seat 5. The plurality of rectangular grooves 7 are respectively connected with the plurality of placement grooves 6. Each connecting plate 10 is slidably installed inside the corresponding rectangular groove 7. An unlocking mechanism is provided on the side of each connecting plate 10 away from the fixing column 9. The unlocking mechanism includes a pressing plate 11. The side wall of the pressing plate 11 is fixedly connected with the side of the connecting plate 10 away from the fixing column 9. The pressing plate 11 is fixedly connected with two sliding Block 12, two sliders 12 are arranged opposite to each other, two slide grooves 13 are provided on both sides of the front and back of the mounting seat 5, each slider 12 is movably installed in the corresponding slide groove 13, the circuit breaker body 1 is taken, and the circuit breaker body 1 is installed on the top of the mounting seat 5, when the bottom of the L-shaped plate 3 encounters the fixing column 9, since the end of the fixing column 9 is an inclined surface, it has a certain force on the fixing column 9, so that the fixing column 9 has a certain force on the spring 8, so that the spring 8 undergoes a certain deformation, and the fixing column 9 is received in the placement groove 6. When the fixing column 9 encounters the through hole 4, the reaction force of the spring 8 causes the fixing column 9 to move out from the inside of the placement groove 6 again, pass through the through hole 4, limit and fix the L-shaped plate 3, and limit and fix the circuit breaker body 1.

[0030] Whenever the circuit breaker body 1 needs to be removed from the mounting seat 5, the pressure plates 11 on both sides are pressed at the same time, so that the pressure plates 11 on both sides are close to each other, thereby driving the connecting plate 10 to move inside the rectangular groove 7, and then driving the fixing column 9 to be received inside the placement groove 6, exerting a certain force on the spring 8, and then the circuit breaker body 1 is removed from the top of the mounting seat 5 for replacement or maintenance.

[0031] Further, refer to Figure 1 Both ends of the circuit breaker body 1 are provided with handles 2, which are convenient for moving the circuit breaker body 1 and installing the circuit breaker body 1 on the top of the mounting seat 5.

Then, the circuit breaker body 1 is moved to the top of the mounting seat 5 through the handle 2, and then the circuit breaker body 1 is installed on the top of the mounting seat 5. When the bottom of the L-shaped plate 3 meets the fixing column 9, since the end of the fixing column 9 is an inclined surface, a certain force is exerted on the fixing column 9, so that the fixing column 9 has a certain force on the spring 8, causing the spring 8 to undergo a certain deformation, and the fixing column 9 is received in the placement groove 6. When the fixing column 9 meets the through hole 4, the reaction force of the spring 8 causes the fixing column 9 to 9 is moved out from the inside of the placement groove 6 again, passes through the through hole 4, and limits and fixes the L-shaped plate 3. When the circuit breaker body 1 is limited and fixed, when the circuit breaker body 1 needs to be removed from the mounting seat 5, the pressure plates 11 on both sides are pressed at the same time, so that the pressure plates 11 on both sides are close to each other, thereby driving the connecting plate 10 to move inside the rectangular groove 7, and then driving the fixing column 9 to be received in the placement groove 6, exerting a certain force on the spring 8, and then the circuit breaker body 1 is moved out from the top of the mounting seat 5 for replacement or maintenance.
