The inner side of the punching cylinder 43 fits the threaded groove 45 and spirally fits the outside of the threaded strip 34 fixedly connected to the outside of the fixed cylinder shell 31. The outside of the annular limiting rotating cylinder 44 is rotatably connected to the inside of the annular limiting channel 53 provided in the male head seat 51. The front end of the fixed cylinder shell 31 is fixedly connected to the rear end of the female head seat 1.

[0029] As a further implementation of this solution, the inside of the plug seat 2 is hollow. The inside of the plug seat 2 is inserted into the outside of the plug 54. The plug seat 2 is inside the fixed cylinder shell 31. The shape of the fixed cylinder shell 31 is a hollow cylinder. The shape of the annular card slot 33 is a ring. The shape of the spiral slideway 32 is a spiral structure. The annular card slot 33 communicates with the spiral slideway 32. The spiral slideway 32 penetrates the rear end of the fixed cylinder shell 31. This design enables the plug seat 2 to be inserted into the outside of the plug 54, facilitating quick insertion and connection stability. The structure allows the communication between the annular card slot 33 and the spiral slideway 32 and penetrates the rear end of the fixed cylinder shell 31, enhancing the overall structural stability and connection reliability. The spiral - shaped spiral slideway 32 not only enhances the structural stability but also, through its communication with the annular card slot 33, helps to achieve quick insertion and stable connection;

[0030] As a further implementation of this solution, the rotating sleeve 41 is in the shape of a hollow cylinder, the annular limiting rotating cylinder 44 is in the shape of a ring, the front end and the rear end of the annular limiting rotating cylinder 44 are equipped with limiting rotating rings, the outer side of the annular limiting rotating cylinder 44 is fitted with the inner side of the through-ring groove 52 opened in the male head seat 51, the outer side of the rotating sleeve 41 is sleeved on the outer side of the male head seat 51, and the design of the hollow-cylindrical rotating sleeve 41 enables it to be sleeved on the outer side of the male head seat 51, increasing the flexibility and stability of the connection. The annular limiting rotating cylinder 44 in the shape of a ring is fitted with the inner side of the through-ring groove 52 of the male head seat 51, increasing the tightness and stability of the connection. At the same time, the design of the limiting rotating rings at the front end and the rear end provides additional stability;

[0031] As a further implementation of this solution, the inner side of the front end of the rotating sleeve 41 is fitted with the inner side of the rear end of the fixed cylinder shell 31. The embedding block 46 is in the shape of a rectangular body, and the outer side of the embedding block 46 is fitted with the inner side of the annular clamping groove 33 opened in the fixed cylinder shell 31, which helps to ensure the stable positioning of the rotating sleeve 41 inside the fixed cylinder shell 31 and enhance the firmness of the connection;

[0032] As a further implementation of this solution, there is a spacing between the punching cylinder 43 and the rotating sleeve 41. The number of the annular limiting rotating cylinders 44 is four, and the punching cylinder 43 is in the shape of a hollow cylinder. The outer side of the punching cylinder 43 is sleeved on the outer side of the annular clamping groove 33. This design allows enough space for the punching cylinder 43 to move when the rotating sleeve 41 rotates, thus enhancing the flexibility and stability of the connection;

[0033] As a further implementation of this solution, one end of the clockwork spring 55 is fixedly connected to the inner side of the annular limiting rotating cylinder 44. The shape of the through-ring groove 52 is a hollow cylinder, and the annular limiting track 53 is communicated with the through-ring groove 52. This fixed connection method helps to provide additional support and stability during the connection process and enhance the firmness of the overall structure. The hollow-cylindrical through-ring groove 52 is communicated with the annular limiting track 53, which helps to achieve better cooperation and stability during the connection process.

[0034] Workflow: When realizing the quick plugging of the radio frequency coaxial connector and ensuring the stability after the connection of the radio frequency coaxial connector, align the plug 54 fixed inside the male head seat 51 with the inside of the plug seat 2, and at the same time, sleeved the rotating sleeve 41 on the outside of the fixed cylinder shell 31, and align the embedding block 46 with the opening at the rear end of the annular card slot 33. Fix the female head seat 1 with one hand, and press the male head seat 51 towards the female head seat 1 with the other hand. At this time, the plugs 54 are inserted into the inside of the plug seat 2. Before the embedding block 46 slides inside the spiral slideway 32, the front end of the impact cylinder 43 fits with the rear end of the thread bar 34 fixed on the outside of the fixed cylinder shell 31. According to the shape of the spiral slideway 32 opened, when the embedding block 46 moves, the embedding block 46 will drive the rotating sleeve 41 to rotate. The rotating sleeve 41 rotates through the annular limiting rotating cylinder 44 inside the through-ring groove 52 opened on the male head seat 51. The annular limiting rotating cylinder 44 is rotatably connected with the annular limiting track 53 opened on the male head seat 51, playing a role in limiting the rotating sleeve 41. When the annular limiting rotating cylinder 44 rotates, the hairspring 55 fixed inside drives elastic energy storage. The rotation of the rotating sleeve 41 drives the impact cylinder 43 to rotate through the spring telescopic rod 42. At this time, when the impact cylinder 43 rotates, the thread groove 45 will not be spirally fitted with the thread bar 34, and the spring telescopic rod 42 will contract. Under the action of the elastic force of the spring telescopic rod 42, it can ensure that the front end of the thread groove 45 is kept in contact with the rear end of the thread bar 34. When the embedding block 46 moves into the annular card slot 33 opened on the fixed cylinder shell 31, under the action of the torsion force of the hairspring 55, it drives the annular limiting rotating cylinder 44 and the rotating sleeve 41 to rotate. At this time, the rotation direction of the rotating sleeve 41 is opposite to that before. The rotating sleeve 41 drives the spring telescopic rod 42 and the thread groove 45 to rotate. The thread groove 45 will be spirally fitted with the outside of the thread bar 34 fixed on the outside of the fixed cylinder shell 31. At the same time, the impact cylinder 43 will move forward, and the spring telescopic rod 42 will extend. Under the action of the embedding block 46 and the annular card slot 33, it can prevent the fixed cylinder shell 31 and the rotating sleeve 41 from separating. Under the combined action of the thread groove 45 and the thread bar 34, it can improve the connection stability of the radio frequency coaxial connector. When pulling out the radio frequency coaxial connector, by rotating the rotating sleeve 41 and moving with a force in the opposite direction to the female head seat 1, the splitting between the passive rotating component 4 and the stable connection component 3 can be realized, achieving the effect of quick plugging and unplugging.

[0035] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
