[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1 to 4 This utility model provides an embodiment of a pneumatic pull-back device for a radio frequency connector heat shrink tubing, comprising a working device 1, which serves as the core base and execution body. Multiple clamping plates 2 are slidably connected to the outside of the working device 1. The clamping plates 2 are designed to move in opposite directions, thereby influencing the gripping and fixing of the heat shrink tubing tail by subsequent components. Sliding strips 3 are slidably connected to both sides of the clamping plates 2, serving as sliding constraints to fix the trajectory. Multiple locking shafts 7 are slidably connected to the inside of a connecting block 4. The connecting block 4 is fixedly connected to the outside of the multiple sliding strips 3, controlling the movement position of subsequent components. Multiple springs 5 ​​are fixedly connected inside the connecting block 4, serving as buffers to reset subsequent components and provide pressure.

[0031] One end of the spring 5 is fixedly connected to a pressing tooth 6. The pressing tooth 6 is designed to be pushed by the spring 5 and ultimately apply force. The external parts of multiple pressing teeth 6 are slidably connected to the inside of the connecting block 4. The external parts of the pressing teeth 6 are fixedly connected to a retaining shaft 7. The retaining shaft 7 is designed to be a locking mechanism. The inside of the clamping plate 2 is provided with multiple slots 8. The slots 8 are designed to accommodate the retaining shaft 7 and cooperate with the retaining shaft 7 to achieve the locking function. The external parts of multiple retaining shafts 7 are engaged with the inside of the clamping plate 2. The external parts of the retaining shaft 7 are engaged with the inside of the slots 8. The external parts of the connecting block 4 are fixedly connected to a pulling arm 9. The pulling arm 9 is designed to transmit pneumatic pulling force. The function of the pulling arm 9 is to rotate and pull back the heat shrink tubing. The external parts of the pulling arm 9 are fixedly connected to a placement plate 10. The placement plate 10 is designed to be a restraint for the heat shrink tubing. The external parts of the placement plate 10 are used to constrain and limit the heat shrink tubing.

[0032] Working Principle: This pneumatic pull-back device for RF connector heat shrink tubing is based on the working device 1. A sliding bar 3 constrains the clamping plate 2 to slide in a straight line, constructing a high-precision pull-back guiding system. The connecting block 4 integrates a spring 5, a pressing tooth 6, and a locking shaft 7, forming an elastic locking mechanism: when the pressing tooth 6 is pressed, the spring 5 is compressed, and the locking shaft 7 disengages from the slot 8 of the clamping plate 2. The sliding clamping plate 2 can quickly adjust the spacing to adapt to different connector specifications. After the spring 5 resets, the locking shaft 7 locks, ensuring stable transmission of the pull-back force, enabling tool-less changeover, and significantly shortening debugging time. The pulling arm 9 and the placement plate 10 adopt a quick-release structure. The placement plate 10 constrains the connector through a customized groove, preventing pull-back deflection and supporting rapid switching of irregularly shaped parts, enhancing production line flexibility. During operation, driving the connecting block 4 causes the pulling arm 9 to move the connector in the opposite direction, and the clamping plate 2 simultaneously pulls back the heat shrink tubing. The contact area between the retaining shaft 7 and the retaining slot 8 is hardened, and the slide bar 3 is equipped with an oil groove or self-lubricating coating to improve wear resistance and lubrication performance; the placement plate 10 is equipped with an anti-misalignment pin to prevent reverse installation and misalignment. This device solves pain points such as difficulty in adapting to multiple specifications, low pull-back accuracy, and poor production line flexibility through adjustable mechanical locking, modular actuator, and high-precision guidance, meeting the high reliability requirements of RF connectors and possessing significant engineering application value in the fields of communications and aviation.

[0033] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
