DETAILED DESCRIPTION
[0050] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0051] In addition, the elements in the present application are referred to as "fixed to" or "provided on" another element, which can be directly on another element or can have a middle element. When an element is considered to be "connected" to another element, it can be directly connected to another element or can have a middle element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not the only implementation.

[0053] A guide positioning structure is provided between the collar 3 and the female head 2, which can rotate and limit the connection of the male head 1 and the female head 2.
[0054] A locking component is provided between the collar 3 and the sleeve 4. When the male head 1 and the female head 2 are connected and the locking component is activated, the locking component can lock the collar 3 and the sleeve 4.
[0055] The female head 2 has a transmission structure inside that is connected to the locking component. The transmission structure cooperates with the guide positioning structure. When the male head 1 and the female head 2 are connected, the guide positioning structure will cooperate with the transmission structure to drive the locking component to move.
[0056] In this solution, the guide positioning structure prevents the male head 1 and female head 2 from rotating during and after insertion, thus providing a positioning effect for the locking component. During insertion, the guide positioning structure cooperates with the transmission structure, causing the transmission structure to move slowly. When the male head 1 and female head 2 are fully inserted, the transmission structure moves quickly and drives the locking component. When the locking component is activated, it can lock the collar 3 and sleeve 4, thus preventing the male head 1 and female head 2 from separating.
[0057] As a further embodiment of this utility model, the guiding and positioning structure includes a plurality of limiting blocks 5 disposed on the inner wall of the collar 3, the plurality of limiting blocks 5 being evenly distributed along the circumference, and the outer wall of the female head 2 being provided with a limiting groove 6 adapted to the limiting blocks 5 along the circumference.

The two sides of the limiting groove 6 near the male connector 1 have chamfers to form an open "outward expansion" structure.
[0059] In this embodiment, since the limiting block 5 and the limiting groove 6 are compatible, when the male head 1 and the female head 2 are connected, multiple limiting blocks 5 will be inserted into multiple limiting grooves 6 respectively. At this time, under the action of the limiting block 5 and the limiting groove 6, the collar 3 and the female head 2 will not be able to rotate relative to each other.
[0060] Due to the shape characteristics of the limiting block 5 and the limiting groove 6, the process of the limiting block 5 moving into the limiting groove 6 is smoother.
[0061] As a further scheme of the utility model, the locking assembly comprises a circular ring 7 rotatably arranged on the outer wall of the sleeve 4 and a plurality of arc-shaped grooves 701 arranged on the circular ring 7, and the plurality of arc-shaped grooves 701 are uniformly distributed along the circumference.

[0063] A plurality of through holes 402 are radially arranged on the sleeve 4, a stop column 9 is slidingly arranged in each of the plurality of through holes 402, and the plurality of stop columns 9 are fixedly connected with the plurality of sliding rods 8 respectively.
[0064] A plurality of stop holes 301 are radially arranged on the sleeve ring 3, the positions of the plurality of stop holes 301 are matched with the positions of the plurality of through holes 402, and when the male head 1 and the female head 2 are completely inserted, the plurality of stop holes 301 and the plurality of through holes 402 are aligned.
[0065] In this embodiment, when the male head 1 and the female head 2 are completely inserted, the plurality of stop holes 301 and the plurality of through holes 402 are aligned, so when the stop column 9 slidingly arranged in the through hole 402 moves into the stop hole 301, the sleeve 4 and the sleeve ring 3 cannot be separated by the interaction between the stop column 9, the through hole 402 and the stop hole 301, thereby realizing the fixation of the male head 1 and the female head 2.
[0066] In addition, the sliding rod 8 is fixedly connected with the stop column 9 and slidingly arranged between the plurality of guide grooves 401 and the plurality of arc-shaped grooves 701, so when the circular ring 7 rotates, the guide groove 401 and the arc-shaped groove 701 will interact, so that the sliding rod 8 drives the stop column 9 to move into the stop hole 301.
[0067] As a further scheme of the utility model, the transmission structure comprises a sliding block 10 and a sliding groove 11 arranged on the female head 2, the sliding groove 11 is arranged along the length direction of the female head 2 and communicates with one of the limiting grooves 6, and the sliding block 10 is slidingly arranged in the sliding groove 11.
[0068] First and second protrusions 12 and 13 are arranged at two ends of the sliding block 10 respectively, and the first protrusion 12 is arranged in the limiting groove 6.

[0070] The fixed rod 17 and the push rod 18 are connected through a hook spring 19, and under the action of the hook spring 19, the rotating plate 16 abuts against the second protrusion 13.
[0071] In this embodiment, since the sliding block 10 is slidably arranged in the sliding groove 11, and the two ends of the sliding block 10 are respectively provided with the first protrusion 12 and the second protrusion 13, and the first protrusion 12 is arranged in the limiting groove 6, when the limiting block 5 slides in the limiting groove 6, the limiting block 5 will abut against the first protrusion 12 and push the first protrusion 12 to slide in the limiting groove 6, and at the same time, the second protrusion 13 will move along with the sliding block 10;
[0072] Since the rotating plate 16 abuts against the second protrusion 13 under the action of the hook spring 19, the second protrusion 13 will drive the rotating plate 16 to rotate around the pin shaft 15 during movement, and in this process, the hook spring 19 will be further stretched, when the rotating plate 16 rotates to the balance position, at this moment, the hook spring 19 is at the maximum stretching amount, and the male head 1 and the female head 2 are completely inserted, the plurality of stop holes 301 and the plurality of through holes 402 are aligned, when the second protrusion 13 moves a little bit again, the hook spring 19 will quickly contract and drive the rotating plate 16 to quickly rotate, and since the push rod 18 is fixed on the rotating plate 16, the push rod 18 will follow the rotating plate 16 to quickly rotate.
[0073] As a further scheme of the utility model, the other end of the pin shaft 15 is rotatably provided with an L-shaped rod 20, the cross plate 14 is provided with an elastic sheet 21, the elastic sheet 21 abuts against the L-shaped rod 20, so that the L-shaped rod 20 always has a tendency to approach the circular ring 7, wherein the L-shaped rod 20 cooperates with the push rod 18;
[0074] One end of the L-shaped rod 20 is provided with a first spherical shell 22, a first ball 23 is rollingly embedded in the first spherical shell 22, one side of the circular ring 7 close to the L-shaped rod 20 is provided with a second spherical shell 24, a second ball 25 is rollingly embedded in the second spherical shell 24, the second ball 25 and the first ball 23 are connected through a connecting rod 26;
[0075] Wherein, the second spherical shell 24 and the first spherical shell 22 are not in the same plane.
[0076] In this embodiment, due to the existence of the elastic sheet 21, the L-shaped rod 20 always has a tendency to approach the circular ring 7; since the L-shaped rod 20 cooperates with the push rod 18, therefore, the push rod 18 will drive the L-shaped rod 20 to rotate around the pin shaft 15 during the process of quickly rotating along with the rotating plate 16;
[0077] Because the first spherical shell 22 fixed on the L-shaped rod 20 has the first rolling ball 23 rollingly embedded in the inside, and the second spherical shell 24 fixed on the circular ring 7 has the second rolling ball 25 rollingly embedded in the inside, and because the second rolling ball 25 and the first rolling ball 23 are connected through the connecting rod 26, and the second spherical shell 24 and the first spherical shell 22 are not in the same plane, therefore, in the process of the rotation of the L-shaped rod 20, the circular ring 7 will follow the rotation;
[0078] When it is needed to separate the male head 1 and the female head 2, the circular ring 7 can be reversely rotated.
[0079] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, but rather can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered in all respects as illustrative and not restrictive, the scope of the present application being indicated by the appended claims rather than that of the above description, and it is intended to be encompassing all changes and modifications which fall within the meaning and scope of the equivalent elements of the claims.
