[0018] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Please see Figures 1-4 This utility model provides a technical solution: a circuit breaker base that is easy to install, comprising: a base 2, a slot 13, and a circuit breaker 1. Both ends of the circuit breaker 1 can be connected to lines, and the current is controlled by closing. The side of the circuit breaker 1 is fixedly connected to the mounting plate 3. Both sides of the mounting plate 3 are provided with sliding grooves 4. The length of the sliding grooves 4 is short and is only used to adjust the angle of the mounting plate 3 so that the arc claws 5 on both sides are subjected to balanced force. The inner wall of the sliding grooves 4 is slidably connected to one end of the arc claws 5. When the circuit breaker 1 and the base 2 are installed, the sliding arc claws 5 can prevent them from tilting. The inner ring surface of the arc claws 5 is provided with a groove 6. The lower end of the mounting plate 3 contacts a fixing frame 16, which can support the mounting plate 3. One side of the fixing frame 16 is fixedly connected to the surface of the base 2 to ensure that the fixing frame 16 can safely and stably support the mounting plate 3.

[0020] Several slots 13 are provided at the upper end of the surface of the base 2. The inner wall of the slots 13 should be rough to increase the friction with the insert plate 15. Connecting posts 7 are fixedly connected to both sides of the surface of the base 2. The length of the connecting posts 7 is greater than that of the mounting plate 3 to avoid the arc claw 5 failing to contact the connecting posts 7. The surface of the connecting posts 7 is provided with grooves 6. A rotating shaft 9 is fixedly connected to the inner wall of the groove 6. The rotating shaft 9 is rotatably connected to the hook plate 12. At this time, the rotation center of the hook plate 12 is determined, and the bent end of the hook plate 12 contacts the groove 6 on the inner ring surface of the arc claw 5. By installing the arc-shaped claw 5 on the surface of the connecting column 7, the mounting plate 3 can be fixed horizontally. By connecting the hook claw 12 to the groove 6 of the arc-shaped claw 5, the mounting plate 3 can be fixed vertically. The other end of the hook plate 12 is rotatably connected to the drive shaft 11, and the other end of the drive shaft 11 is rotatably connected to the rotating seat 10. The other end of the rotating seat 10 is fixedly connected to the surface of the sliding column 8. When the sliding column 8 moves up and down, the drive shaft 11 can drive the hook plate 12 to rotate. The length of the groove 6 is greater than that of the hook plate 12 to prevent the hook plate 12 from not being able to retract completely.

[0021] The sliding column 8 is fitted inside the connecting column 7. The connecting column 7 is hollow to facilitate the sliding of the sliding column 8. The diameter of the hollow part of its inner wall is larger than that of the sliding column 8. The upper end of the sliding column 8 is fixedly connected to the telescopic rod 14. The length of the sliding column 8 is greater than that of the connecting column 7. One end of the telescopic rod 14 is fixedly connected to the insert plate 15. The position of the insert plate 15 can be moved and rotated by sliding the telescopic rod 14. The other end of the telescopic rod 14 passes through the sliding column 8. The insert plate 15 is located in the slot 13 and contacts it. The surface of the insert plate 15 should be rough. At this time, the sliding height of the sliding column 8 is fixed and will not move upward due to the weight 3 of the circuit breaker 1.

[0022] In actual use, after verifying that the device is correct, the arc-shaped claws 5 on both sides of the mounting plate 3 are engaged with the surface of the connecting column 7. Then, the sliding plates 8 on both sides are slid down. At this time, the rotating seat 10 moves down, and both ends of the transmission shaft 11 will begin to move down, and its tilt angle changes. During this process, the end of the hook plate 12 that contacts the transmission shaft 11 moves down, and the other end of the hook plate 12 rotates toward the groove 6 on the inner ring surface of the arc-shaped claw 5 and hooks the arc-shaped claw 5. Then, the insert plate 15 is inserted into the corresponding slot 13 to complete the fixing of the circuit breaker 1. The device is easy to operate and does not require the use of fixing bolts, etc., and can be installed quickly.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
