[0030] The locking assembly 32 includes a movable hole 321 and a rotating shaft 322, a torsion spring 323, a torsion block 324, a limit block 325, and a locking plug 326 on the connecting arm 315. The locking plug 326 is fixed to the outer surface of the female connector 10, and the locking plug 326 can be inserted into the movable hole 324. The rotating shaft 322 rotates in the movable hole 324. A flat positioning groove 327 is provided on the inner side of the rotating shaft 322. The positioning groove 327 can abut against the bottom of the locking plug 326. The limit block 325 is fixed in the movable hole 324 and abuts against the outer side of the rotating shaft 322 to limit the rotation range of the rotating shaft 322. One end of the rotating shaft 322 extends from the connecting arm 315. The torsion block 324 is installed on the connecting arm 315 extending from the rotating shaft 322. When the torsion spring 323 is in the state that the locking plug 326 abuts against the outer surface of the arc of the rotating shaft, the rotating shaft 322 is tightly abutted under the locking plug 326 under the restriction of the torsion spring 323. The rotating shaft 322 is rotated by toggling the torsion block 324 so that the positioning groove 327 is located under the locking plug 326. At this time, a gap is generated between the locking plug and the rotating shaft, so that the rotating shaft can be detached from the male connector 20. The torsion block 324 is loosened, and the elastic deformation ability of the torsion block 324 causes the rotating shaft 322 to reset, which is convenient for the next locking.

[0033] The shaft seat 314 is integrally formed with the female connector 10, and its top extends out of the top of the female connector 10 to form an extension portion. The top surface of the extension portion can abut against the lower end of the male connector 20, so that there is a gap between the connection, which is convenient for inserting a tool to separate the two; the outer side surface of the connecting arm 315 and adjacent to the movable hole 322 is provided with an outwardly protruding gripping end 315.1. Gripping the gripping end 315.1 is equivalent to having a power point, and people can easily hold the gripping end 315.1 with one hand and twist the torsion block 324 with the other end.

[0034] There are several locking parts 30 distributed along the axial direction of the female connector 10. The number can be set according to demand, preferably two, symmetrically arranged on both sides of the female connector 10.

[0035] When the utility model is in use:

[0036] When the connecting arm is in the expanded state, the male connector is inserted into the female connector, and then the connecting arm is pulled so that the connecting arm abuts against the outer surface of the female connector. At this time, the cam is driven to rotate so that the outer edge abuts against the recess of the male connector. At the same time, the locking plug is inserted into the movable hole and abuts against the outer surface of the arc at the upper end of the rotating shaft, completing the locking of the male connector and the female connector. When the toggle block is turned to rotate the rotating shaft, the positioning groove is located under the locking plug. At this time, a gap is generated between the locking plug and the rotating shaft, so that the rotating shaft can be detached from the male connector. When the toggle block is loosened, the elastic deformation ability of the toggle block resets the rotating shaft, which is convenient for the next locking.
