A connector socket 8 is electrically connected to the end of transmission line 2 6 near connector 7, which mates with connector 7. A limit strip 1 9 is fixedly connected to the outer wall of connector socket 8, which mates with limit strip 2 30, ensuring that the threaded cap 10 can only be positioned within a certain range on the outer wall of connector socket 8. The device moves within the enclosure. A socket block 29 is fixedly connected to one end of the connector 8 away from the transmission line 26, engaging with the plug port 28. A groove 35 is formed on the outer wall of the socket block 29, engaging with a protrusion 33. A threaded cap 10 is slidably connected to the outer wall of the connector 8, engaging with a thread 27. A limiting strip 20 is fixedly connected to the inner wall of the threaded cap 10, engaging with a limiting strip 19. A washer 31 is fixedly connected to the inward side of the limiting strip 20, increasing the friction and sealing between the limiting strip 19 and the limiting strip 20. The inner wall of the limiting strip 20 is slidably connected to the outer wall of the connector 8. The inner wall of the plug port 28 and the outer wall of the socket block 29 are slidably connected. The outer wall of the protrusion 33 is slidably connected to the inner wall of the groove 35, preventing the connection between the plug port 28 and the socket block 29 from rotating. The inner wall of the threaded cap 10 is threadedly connected to the surface of the thread 27, providing a detachable fixation.

[0032] A pin is provided in the middle of the plug 28, and a pin hole is provided in the middle of the plug 28. The outer wall of the pin and the inner wall of the pin hole are slidably connected and correspond one-to-one. The diameter of the through hole 34 is larger than the outer diameter of the spring shaft 24, allowing the spring shaft 24 to pass through. A cover plate 11 is fixedly connected to the upper surface of the fixing base 1 and installed on the fixing base 1 to prevent the internal snap-fit ​​fixing strip 19 structure of the fixing base 1 from being exposed and damaged. A threaded hole 18 is opened on the upper surface of the fixing base 1, and a through hole 32 is opened on the surface of the cover plate 11. The number of threaded holes 18 and through holes 32 are... There are four of each, and they correspond one-to-one. The threaded hole 18 and the through hole 2 32 cooperate to allow the cover plate 11 to be installed on the fixed base 1 and protect the internal structure. The threaded hole 18 and the through hole 2 32 are connected by a screw 12. The handle 13 is spherical in shape for easy gripping. The first gasket 4, the second gasket 17 and the washer 31 are all made of rubber to increase friction and enhance sealing. The surface of the cover plate 11 has a square groove 36. The square groove 36 cooperates with the buckle 14 to enter the interior of the fixed base 1. There are three of each of the pins 26 and the holes 16, and they correspond one-to-one.

[0033] Working principle: When antenna 2 needs to be removed from mounting base 1, a pulling force is applied to handle 13 in a horizontal direction away from antenna 2. The locking strip 19 will slide along the slide seat 20 away from the buckle 14. Then, a vertical force is applied to antenna 2 to disengage it from mounting base 1. Due to the cooperation between pin 26 and socket 16, the work of removing antenna 2 from mounting base 1 is completed. When transmission line 1 5 and transmission line 2 6 need to be separated, due to the threaded connection, thread cap 10 is removed from thread 27. Due to the sliding cooperation between plug 28 and socket block 29, and the sliding cooperation between protrusion 33 and groove 35, the connection plug 7 is completed. Separating the connector 8 from the transmission line 5 and the transmission line 6 facilitates the disassembly of the antenna 2. When the antenna 2 needs to be installed on the mounting base 1, the transmission line 5 and the transmission line 6 are connected first. The sliding engagement of the plug 28 and the socket block 29, and the sliding engagement of the protrusion 33 and the groove 35 complete the connection between the connector 7 and the connector 8. The threaded cap 10 and the thread 27 are then threaded together to fix the connector 7 and the connector 8. The sliding engagement of the pin 26 and the socket 16, the sliding engagement of the buckle 14 and the buckle fixing strip 19, and the mutual engagement of the spring 23 and the spring block 22 complete the installation of the antenna 2.

[0034] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
