[0026] In this embodiment, specific reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The adjustment component 6 includes a mounting block 601 and a slide rail 602. The mounting block 601 is mounted on the inner wall of the arc-striking plate 1. The cross section of the mounting block 601 is an L-shaped structure. The mounting block 601 is located on one side of the slide rail 602. An elastic clip 603 is plugged and connected to the inner wall of the mounting block 601. The elastic clip 603 is an arc-shaped structure. The slide rail 602 is mounted on the inner wall of the arc-striking plate 1. The cross section of the slide rail 602 is a concave structure. A sliding block 604 is slidably connected to the inner wall of the slide rail 602. The cross section of the sliding block 604 is an inverted T-shaped structure. A pull rod 605 is installed on the outer wall of the sliding block 604. The pull rod 605 is located on one side of the limit clamp 606. A limit clamp 606 is arranged on the outer wall of the sliding block 604. The cross section of the limit clamp 606 is an L-shaped structure, and the inner wall of the limit clamp 606 is connected with an elastic clip 603.
[0027] Among them, a connecting piece 7 is provided on the outer wall of the arc-striking plate 1, one end of the connecting piece 7 contacts the impact electromagnet for connection, the outer wall plane of the planar portion 5 and the top plane of the arc-striking point plate 3 are relatively flush, the arc-striking plate 1 is an arc-shaped structure, and the adjusting component 6 is located in the inner cavity of the arc-striking plate 1, so that the adjusting component 6 can adjust the shape of the elastic clip 603, so that the elastic clip 603 is stuck in the installation position for fixation, and the bending portion 4 is located on one side of the planar portion 5.
[0028] When the new arc-striking piece used in the small circuit breaker of the present invention is working, the overall volume of the improved arc-striking piece plate 1 is reduced, a bending portion 4 is provided on the outer wall of the arc-striking piece plate 1, and a groove 2 is formed between the bending portion 4 and the arc-striking piece plate 1, an arc-striking point piece 3 is provided in the groove 2, and the outer wall plane of the plane portion 5 and the top plane of the arc-striking point piece 3 are relatively flush. Through this structural setting, the arc-striking point piece 3 is not easy to be burned, and the arc-striking point piece 3 has a better arc-striking effect and a longer service life, thereby solving some defects in the current arc-striking piece design. Its large size and the protruding design of the silver contact make it easy to be burned during operation.

A pull rod 605 is installed on the outer wall of the sliding block 604. Under the action of a limit clamp 606, when encountering installation positions of different types of circuit breakers, it is only necessary to toggle the pull rod 605 to make the pull rod 605 drive the sliding block 604 to slide on the inner wall of the slide rail 602, and then make the sliding block 604 drive the limit clamp 606 to move. The mounting block 601 is installed on the inner wall of the arc-striking plate 1, and an elastic clip 603 is plugged and connected to the inner wall of the mounting block 601, and the inner wall of the limit clamp 606 is connected to the elastic clip 603. When in use, the limiting clamp block 606 applies a thrust to the elastic clamp 603. At the same time, since the other end of the elastic clamp 603 is clamped and limited by the mounting block 601, the elastic clamp 603 bulges toward the middle, and the inner diameter of the arc-striking plate 1 can be adjusted, so that the arc-striking plate 1 is stuck on the inner wall of the circuit breaker for fixation, thereby solving the problem that the currently used arc-striking plate design is fixed in size and has no diameter adjustment function. This design limits its versatility in various types of circuit breakers, resulting in compatibility problems during the installation process. Since it cannot adapt to the specific needs of different equipment, the practicability of the arc-striking plate is greatly affected, which may become a significant limitation in different application scenarios.
