[0002] During the long-term operation of low-voltage circuit breakers, various faults are inevitable, requiring maintenance personnel to use detection devices to detect and repair them. Traditional low-voltage circuit breaker detection devices are generally composed of test leads and detectors. The test lead plug is inserted into the detector. For frame-type low-voltage circuit breakers, during detection, it is often necessary to place one test lead against the circuit breaker, and then use the other test lead to contact different positions on the circuit breaker to troubleshoot the circuit breaker fault.

[0003] According to the description of an improved low-voltage circuit breaker detection device disclosed on the patent website (authorization announcement number: CN219936047U), "the utility model belongs to the field of low-voltage circuit breaker detection devices, specifically an improved low-voltage circuit breaker detection device, comprising a long plate; a cavity is formed inside the long plate, and a fixing mechanism is provided inside the cavity; the fixing mechanism comprises a screw, the front end of the screw is rotatably connected to the inner wall of the cavity, the rear end of the screw is fixedly connected to a nut, a moving block is threadedly connected to the screw, the top end of the moving block is rotatably connected to the bottom end of a collar, the collar is sleeved on a connecting wire, the front end of the connecting wire is fixedly connected to a meter head, the rear end of the connecting wire is inserted into the detector body, the connecting wire is provided with two groups, the front end of the collar is fixedly connected to a washer, and the washer is made of rubber; the function of fixing the meter head is achieved through the structural design of the fixing mechanism."

[0004] In view of the above description, the applicant believes that the following problems exist:

[0005] During use, the utility model prevents the collar from rotating backward by abutting the limit block against the rear end of the collar, thereby ensuring that the collar will not rotate backward when fixing the meter head. However, due to the uneven surface of the short-circuit breaker, it is necessary to contact the short-circuit breaker surface at different positions to troubleshoot the fault. However, due to the limitation of the collar by the limit block, the rotation angle of the collar is limited, and it is impossible to contact the short-circuit breaker surface at different positions, which will lead to inaccurate circuit breaker fault troubleshooting, reduce its detection accuracy, and reduce its detection efficiency. Therefore, it is necessary to improve the low-voltage circuit breaker quality detection device to solve the above problems. Utility Model Content
