One end of the first support spring 11 is fixedly connected to the upper fixing block 5. A lower fixing block 3 is arranged below the upper fixing block 5. There is a separation structure on one side of the lower fixing block 3 that is the same as that of the upper fixing block 5. One side of the lower fixing block 3 is in contact with the connecting ring 6. A support ring 4 is fixedly connected to the inside of the upper fixing block 5. Another support ring 4 is fixedly connected to the inside of the lower fixing block 3. The two support rings 4 are in contact with each other. The other end of the protective pipe 1 is fixedly connected to a connecting block 10. A plug rod 13 is fixedly connected to the lower end of the upper fixing block 5. One side of the plug rod 13 is inserted into the lower fixing block 3. An activity groove 15 is opened on one side of the lower fixing block 3. A second support spring 16 is fixedly connected to one side of the activity groove 15. A blocking rod 14 is slidably connected to one side of the activity groove 15. A card slot 17 is opened on one side of the plug rod 13. The blocking rod 14 is slidably connected to one side of the card slot 17.

By setting the second support spring 16, the activity groove 15, and the activity plate 18, the blocking rod 14 is moved.

[0029] During use, the protective tube 1 is sleeved outside the breakaway valve. The upper fixing block 5 is moved downward, and the lower fixing block 3 moves in the opposite direction. As a result, the support ring 4 comes into contact with the breakaway valve. When making contact, the insertion rod 13 is inserted into the lower fixing block 3. Then, the second support spring 16 pushes the blocking rod 14 to move within the movable slot 15 until it moves into the card slot 17, fixing the insertion rod 13 to the lower fixing block 3. Thus, the lower fixing block 3 is fixedly connected to the upper fixing block 5 and fixed to the breakaway valve. When disassembling, the movable plate 18 is slid to drive the blocking rod 14 out of the card slot 17. Then, the first support spring 11 moves the upper fixing block 5 and the lower fixing block 3 upward and downward, separating the protective sleeve from the breakaway valve, achieving the purpose of facilitating the installation and removal of the protective sleeve. Embodiment

[0030] Please refer to Figures 1 to 9 As shown in the figure, the present utility model provides a technical solution: a breakaway valve protective sleeve, including a protective tube 1. One side of the protective tube 1 is fixedly connected with a connecting plate 20. One side of the connecting plate 20 is provided with a protective shell 7. A limiting groove 23 is opened on one side of the protective shell 7 and extends to the connecting block 10. A limiting rod 8 is slidably connected to one side of the limiting groove 23. One end of the protective tube 1 is fixedly connected with a connecting ring 6. One side of the connecting ring 6 is provided with an upper fixing block 5. The lower end of the upper fixing block 5 is provided with a lower fixing block 3. One side of the lower fixing block 3 is in contact with the connecting ring 6. The inner side of the upper fixing block 5 is fixedly connected with a support ring 4. The other end of the protective tube 1 is fixedly connected with a connecting block 10. One side of the protective shell 7 is in contact with the connecting block 10. A connecting rod 2 is sleeved inside the connecting block 10. The connecting rod 2 penetrates through the two connecting blocks 10. A support block 9 is inserted on one side of the connecting rod 2. The inside of the protective shell 7 is in contact with the connecting rod 2 and the support block 9. One side of the support block 9 is in contact with the connecting block 10. A blocking block 21 is slidably connected to one side of the connecting rod 2. The upper end of the blocking block 21 is circular. One side of the blocking block 21 is in contact with the support block 9. The lower end of the blocking block 21 is fixedly connected with a third support spring 19. One end of the third support spring 19 is fixedly connected with the connecting rod 2. By providing the connecting rod 2 and the support block 9, the connecting block 10 is connected. By providing the blocking block 21 and the third support spring 19, the support block 9 is blocked. By providing the protective shell 7 and the connecting plate 20, the support block 9 and the connecting rod 2 are protected. By providing the limiting rod 8 and the limiting groove 23, the support block 9 and the connecting rod 2 are prevented from being separated due to slight force.

[0031] In use, the protective tube 1 is sleeved on the pull - off valve respectively. The connecting rod 2 is inserted into the connecting block 10 so that one end of the connecting rod 2 penetrates into the support block 9. The third support spring 19 pushes the stopper 21 out of the connecting rod 2, enabling the connecting rod 2 to block the support block 9, connecting the two connecting blocks 10, and thus connecting the two protective tubes 1. Then, the protective shell 7 is connected to the connecting plate 20, covering the structure that connects the two connecting blocks 10. Next, the limiting rod 8 is snapped into the limiting groove 23, connecting the two protective shells 7. When the pull - off valve separates, the two protective tubes 1 are pulled, driving the connecting blocks 10 to move to both sides. Since the upper end of the stopper 21 is circular, when the pulling force between the support block 9 and the connecting rod 2 is large, the stopper 21 is squeezed by the support block 9, causing the support block 9 to separate from the connecting rod 2, and thus the two protective tubes 1 separate. The arrangement of the limiting groove 23 and the limiting rod 8 restricts the protective shell 7, preventing the support block 9 and the connecting rod 2 from separating with a little force. The limiting rod 8 is made of plastic and can break under force, facilitating the separation of the protective tube 1, achieving the purpose that the protective sleeve separates when the pull - off valve separates.

[0032] The above - mentioned is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
