[0014] The following is a detailed description of the new use with reference to the accompanying drawings:

[0015] like Figure 1 and 2 As shown, an auxiliary positioning device for a connecting rod of an operating mechanism of a low-voltage distribution cabinet comprises a cabinet body 1, which is an existing conventional low-voltage distribution cabinet body. A cabinet door 2 is provided at the front end of the cabinet body 1, and the edge of the cabinet door 2 is hinged to the edge of the cabinet body 1. A molded case circuit breaker 3 is provided in the cabinet body 1, and a connecting rod 4 is provided on the molded case circuit breaker 3. The connecting rod 4 faces the front end of the cabinet body 1, and the molded case circuit breaker 3 can be controlled by rotating the connecting rod 4. A card plate 5 with a trapezoidal structure is provided at one end of the connecting rod 4 close to the cabinet door 2, and a sleeve 6 that penetrates the cabinet door 2 and corresponds to the connecting rod is provided on the cabinet door 2, and a rotating shaft 7 is provided in the sleeve 6, and both ends of the rotating shaft 7 are respectively connected from both ends of the sleeve 6 Extending out, the rotating shaft 7 can rotate in the sleeve 6. In order to prevent the rotating shaft 7 from moving in the sleeve 6 along the length direction of the sleeve 6, the rotating shaft 7 is provided with a first shaft ring 8 and a second shaft ring 9. The first shaft ring 8 is located on the inner side of the cabinet door 2, and the second shaft ring 9 is located on the outer side of the cabinet door. The sleeve 6 is located between the first shaft ring 8 and the second shaft ring 9. The rotating shaft 7 is positioned by the first shaft ring 8 and the second shaft ring 9. The inner end of the rotating shaft 7 is provided with a card slot 10 corresponding to the card plate 5. When the cabinet door 2 is closed, the card plate 5 can extend into the card slot 10. A positioning plate 11 is fixed at the inner end edge of the rotating shaft 7, and an angle of 20-50 degrees is formed between the positioning plate 11 and the rotating shaft 7.

[0016] In addition, a handle 12 for rotating the shaft 7 is provided at the outer end of the shaft 7 .

[0017] The usage of this new type of application is as follows:

[0018] After the low-voltage distribution cabinet has been used for a period of time, its internal related components will be damaged. Under the action of gravity, the connecting rod 4 of the molded case circuit breaker 3 tilts downward near one end of the cabinet door 2. Before closing the cabinet door 2, the connecting rod 4 is first rotated so that the card plate 5 at one end of the connecting rod 4 is in a vertical state, and then the rotating shaft 7 is rotated by the handle 13 to make the card slot 10 in a vertical state, and the positioning plate 11 is located directly below the card slot 10, and then the cabinet door 2 can be closed. When closing the cabinet door 2, the end of the positioning plate 11 away from the rotating shaft 7 first contacts the bottom of the card plate 5 at one end of the connecting rod 4. As the cabinet door 2 moves, the card plate 5 also moves relative to the positioning plate 11. During the movement, the card plate 5 moves on the upper surface of the positioning plate 11 and along the upper surface of the positioning plate 11 relative to the card slot 10 of the rotating shaft 7. The height of the card plate 5 is lifted by the positioning plate 11. When the card plate 5 moves to the end of the positioning plate 11 close to the rotating shaft, the height of the card plate 5 corresponds to the card slot 10, and the card plate 5 can enter the card slot 10.
