[0033] In this embodiment, a connecting tube 11 is fixedly provided on the outside of the buckle 19, and a slot 15 is provided inside the connecting tube 11. The slot 15 is fitted with the buckle 19. Through the slot 15 and the buckle 19, better positioning and fixing can be provided during insertion and removal, reducing loosening and shaking, and ensuring the stability of the test probe during use.

[0034] A connecting block 14 is fixedly provided on the lower end face of the rotating shaft 3, and a positioning plate 18 is fixedly provided on the outer side of the connecting block 14. The positioning plate 18 can cooperate with other components in the future to play a positioning and guiding role, which helps to improve the accuracy and convenience of insertion and removal.

[0035] A protective tube 4 is fixedly provided on the lower end face of the rotating shaft 3, and the buckle 19 is inside the protective tube 4. A threaded tube 12 is fixedly provided on the outside of the protective tube 4. The protective tube 4 is used to protect the buckle 19 and prevent the buckle 19 from being damaged during insertion and removal.

[0036] The connecting tube 11 has a positioning groove 16 inside, and the positioning plate 18 is slidably set with the positioning groove 16. Through the positioning plate 18 and the positioning groove 16, the connection accuracy between the test needle body 2 and the connecting tube 11 can be guaranteed, and the connection failure caused by the offset can be avoided.

[0037] A connecting seat body 1 is fixedly provided on the outside of the connecting tube 11. A threaded hole 10 is provided inside the connecting seat body 1, and the threaded hole 10 is spirally arranged with the threaded tube 12. Through the connecting tube 11, it is convenient to modularly produce and assemble the test needle connecting seat, which improves production efficiency and product maintainability.

[0038] A mounting plate 8 is fixedly provided on the right end face of the connector body 1, and a fixing plate 7 is fixedly provided on the upper end face of the mounting plate 8. The fixing plate 7 is fixedly set with the connector body 1. A threaded rod 6 is fixedly provided inside the fixing plate 7. The connector body 1 can be fixed on other equipment through the fixing plate 7 and the threaded rod 6, which enhances the practicality and stability of the connector.

[0039] The left end face of the connector body 1 is provided with a mounting groove 9, and the mounting groove 9 is slidably disposed with the mounting plate 8. The upper end of the interior of the connector body 1 is provided with a threaded hole 5, and the threaded hole 5 is spirally disposed with the threaded rod 6. Through the mounting plate 8 and the mounting groove 9, the connector body 1 is more convenient to disassemble and maintain when needed, saving time and effort.

[0040] The working principle and process of a convenient plug-in / plug-out test probe connector:

[0041] When starting the connection, first lift the test probe body 2 and align the positioning post 17 on the lower end of the rotating shaft 3 with the corresponding position on the connecting tube 11 on the connecting seat body 1. The positioning post 17 serves as a preliminary positioning point, allowing the test probe body 2 to roughly find the connection direction, laying the foundation for subsequent operations. Next, insert the buckle 19 at the lower end of the rotating shaft 3 into the connecting tube 11. Since the groove 15 inside the connecting tube 11 fits snugly with the buckle 19, the two fit tightly after insertion, achieving preliminary horizontal fixation of the test probe. At the same time, the positioning plate 18 on the outside of the connecting block 14 will slide along the positioning groove 16 inside the connecting tube 11, further ensuring the accuracy and stability of the insertion and preventing deviation. The threaded tube 12 on the outside of the protective tube 4 and the threaded hole 10 inside the connecting seat body 1 are important connection structures. After the buckle 19 is inserted, rotate the test probe body 2 to make the threaded tube 12 and the threaded hole 10 spirally connected. This threaded connection method enhances the firmness of the connection. The test probe body 2 is tightly connected to the connector body 1. If multiple connector bodies 1 need to be spliced, slide the mounting plate 8 on the right end of one connector body 1 into the mounting groove 9 on the left end of another connector body 1. Then, align the threaded rod 6 in the fixing plate 7 with the threaded hole 5 of another connector body 1 and rotate it to splice the two connector bodies 1. When disassembling the test probe body 2, first rotate the test probe body 2 in the opposite direction to gradually loosen the threaded tube 12 and the threaded hole 10, releasing the main fixing force. Continue to pull the test probe body 2 upward to let the buckle 19 disengage from the slot 15. The positioning plate 18 exits along the positioning groove 16 to separate the test probe body 2 from the connector body 1. If the connector body has been spliced ​​before, rotate the threaded rod 6 in the opposite direction to make it exit from the threaded hole 5, and then slide the mounting plate 8 out of the mounting groove 9 to complete the separation of the connector body 1. This provides a convenient test probe connector for insertion and removal.
