An installation groove 11 is formed in the rear side of the circuit breaker body 10 in a left-right penetrating manner. An upper clamping seat 13 is integrally formed on the upper side of the installation groove 11 of the circuit breaker body 10. The width of the installation groove 11 should be slightly wider than the width of the installation plate 8. The installation plate 8 should be able to bypass the upper clamping seat 13 and enter the installation groove 11, and then move the utility model downward so that the upper clamping seat 13 is clamped on the rear side of the upper end of the installation plate 8. In the utility model, a movable frame 30 is arranged in the lower side of the installation groove 11 of the circuit breaker body 10 in a vertical sliding manner, and an elastic mechanism for pushing the movable frame 30 upward is arranged on the circuit breaker body 10. The movable frame 30 includes a lower clamping plate 31 facing the installation groove 11. The lower clamping plate 31 is used for clamping on the rear side of the lower end of the installation plate 8. Through the cooperation of the upper clamping seat 13 and the lower clamping plate 31, the utility model can be fixedly installed on the installation plate 8. In the utility model, an operating rod 40 is rotatably connected to the lower side of the circuit breaker body 10. The front end of the operating rod 40 extends towards the front side of the circuit breaker body 10, and the rear end of the operating rod 40 is connected to the movable frame 30. The operating rod 40 is used for driving the movable frame 30 to move downward when its front end is pressed towards the circuit breaker body 10.

[0025] Working principle of the utility model: When the utility model is installed on the installation plate 8, press the front end of the operating rod 40 towards the circuit breaker body 10, and the rear end of the operating rod 40 will control the movable frame 30 to move downward. At this time, the lower clamping plate 31 on the movable frame 30 will exit the installation groove 11. Then, align the installation groove 11 of the utility model with the installation plate 8, make the installation plate enter the installation groove 11, and make the upper end of the installation plate 8 enter the front side of the upper clamping seat 13. Then release the front end of the operating rod 40, and the elastic mechanism will push the movable frame 30 upward, so that the lower clamping plate 31 on the movable frame 30 enters the installation groove 11 and presses on the rear side of the lower end of the installation plate 8. Therefore, through the action of the upper clamping seat 13 and the lower clamping plate 31, the utility model is fixed on the installation plate 8, as Figure 6 is a schematic structural diagram of the utility model installed on the installation plate 8. When disassembling, only need to press the front end of the operating rod 40 towards the circuit breaker body 10, and the utility model can be removed from the installation plate 8. To sum up, during the disassembly and assembly process of the utility model, the operator can easily complete the disassembly and assembly operations from the side of the circuit breaker away from the installation plate, which also improves the safety of the operator.

[0026] The specific structure of the operating rod 40 rotatably connected to the lower side of the circuit breaker body 10 is: A hinge seat 14 is fixedly connected to the lower side of the circuit breaker body 10, and the middle part of the operating rod 40 is rotatably connected to the hinge seat 14. Note that there should be a space for pressing between the front end of the operating rod 40 and the circuit breaker body 10.

[0027] The specific structure in which the rear end of the operating rod 40 is connected to the movable frame 30 is that a control port 32 is formed on the lower side of the movable frame 30. The rear end of the operating rod 40 passes through the control port 32 and is integrally formed with a bent baffle 41 that bends downward. This structure enables the operating rod 40 to effectively drive the movable frame 30 and prevent the movable frame 30 from disengaging from the operating rod 40.

[0028] In order to facilitate the user to press the operating rod 40 by hand, a plurality of anti-slip lines 42 are provided at the front end of the lower side surface of the operating rod 40.

[0029] The specific structure in which the movable frame 30 is slidably arranged up and down on the lower side of the installation groove 11 is as follows: An assembly port 12 is formed on the lower side of the installation groove 11 at the rear side of the circuit breaker body 10, and a limit seat 20 is provided in the middle of the assembly port 12. A push groove 21 is formed in the middle of the limit seat 20. The movable frame 30 is slidably fitted on the limit seat 20. Specifically, the movable frame 30 includes a panel 33 that fits against the rear side of the limit seat 20, and side plates 34 are integrally formed on both the left and right sides of the panel 33 and are located on both the left and right sides of the limit seat 20. Among them, the lower clamping plate 31 is located at the upper end of the side plate 34. Since there are two side plates 34, there are also two lower clamping plates 31. A push plate 35 that extends into the push groove 21 is integrally formed on the panel 33. The elastic mechanism includes a spring 50. The spring 50 is located in the push groove 21 and is used to push the push plate 35 upward, so as to move the entire movable frame 30 upward. In addition, the control port 32 is located on the lower side of the panel 33.

[0030] Furthermore, anti-disengagement plates 22 are integrally formed on both the left and right sides of the limit seat 20, and limit plates 36 that extend to the front side of the anti-disengagement plates 22 are integrally formed at the front ends of the side plates 34. This structure can prevent the movable frame 30 from disengaging rearward from the limit seat 20. Still further, a pressing plate 60 is provided between the anti-disengagement plate 22 and the limit plate 36. The pressing plate 60 is slidably arranged back and forth between the anti-disengagement plate 22 and the limit plate 36. A pressing spring 70 for pushing the pressing plate 60 forward is provided between the pressing plate 60 and the anti-disengagement plate 22. The pressing plate 60 is used to press against the limit plate 36, so that when the present invention is installed on installation plates of different thicknesses, the lower clamping plate 31 can be pressed against the installation plate.

[0031] Among them, a plurality of guide posts 61 are fixedly connected to the pressing plate 60, and guide holes 23 corresponding to the guide posts 61 are formed in the anti-disengagement plate 22. The guide posts 61 are movably fitted in the guide holes 23. This structure can enable the pressing plate 60 to be stably slidably arranged back and forth between the anti-disengagement plate 22 and the limit plate 36, and the number of springs 50 corresponds to that of the guide posts 61 and is correspondingly sleeved on the guide posts 61.

[0032] It should be noted that the terms used in the present utility model, such as "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. This is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the protection scope of the present utility model.
