[0064] Multiple gas transmission cylinders 30 are evenly and fixedly connected to the outside of the supporting ring 27, and the bottom end of the gas transmission cylinder 30 is connected to the deformation airbag 28. The middle part of the top of the gas transmission cylinder 30 is vertically slidably connected to a push rod 31, and one end of the push rod 31 located inside the gas transmission cylinder 30 is fixedly connected to a push piece 32.

[0066] Example 2:

[0067] See also Figure 1-9 This embodiment provides a technical solution based on the first embodiment: the quick-install assembly 10 includes:

[0068] The carrying tube 33 is fixedly connected to the other end of the extension tube 6. An assembly cavity is defined between the inner and outer walls of the carrying tube 33. A quick-release ring 34 is slidably connected to the interior of the assembly cavity. Limiting holes 35 communicating with the assembly cavity are defined at both ends of the carrying tube 33. Limiting rods 36 are slidably connected to the interiors of the two limiting holes 35. One end of the limiting rod 36 located inside the assembly cavity is also fixedly connected to the quick-release ring 34.

[0069] The transmission ring 37 is fixedly connected to one end of the two limiting light rods 36 away from each other. The outer side of the carrying cylinder 33 is fixedly connected to a positioning seat 38 corresponding to the gas transmission cylinder 30. The top of the positioning seat 38 is rotatably connected to the carrying shaft 39. The two ends of the carrying shaft 39 are respectively fixedly connected to the positioning card plate 40 and the pressing plate 41. One side of the positioning card plate 40 is rotatably connected to the guide plate 43. The end of the guide plate 43 away from the positioning card plate 40 is also rotatably connected to the transmission ring 37.

[0070] The transmission seat 44 is fixedly connected to one end of the carrying tube 33. The transmission seat 44 is internally rotatably connected to a transmission screw 45. The outer side of the transmission screw 45 is threadedly connected to a displacement push plate 46, and one end of the displacement push plate 46 is also fixedly connected to the transmission ring 37.

[0071] In this embodiment, the positioning clamp 40 is an L-shaped structure that can cooperate with the carrying ring 27 to effectively position the extension tube 6. Here, in order to increase the friction between the positioning clamp 40 and the carrying ring 27, an anti-slip plate is fixedly connected to one side of the carrying ring 27 and the end of the positioning clamp 40 away from the carrying shaft 39, and the anti-slip plate has anti-slip grooves.

Through the setting of the pressing groove 42, when the pressing plate 41 is flipped toward the push rod 31, the push rod 31 can be moved into the inner side of the pressing groove 42. When the pressing plate 41 contacts the baffle, as the pressing plate 41 continues to press, the push rod 31 can be pushed to slide adaptively.

[0073] In this embodiment, the outer side of the transmission ring 37 is fixedly connected with a mounting ear corresponding one-to-one to the guide plate 43, and the end of the guide plate 43 away from the positioning card plate 40 is connected to the mounting ear through a rotating shaft. Through the setting of the mounting ear, the rotating shaft can be stably mounted to ensure the smoothness of the connection between the guide plate 43 and the positioning card plate 40 and the pressing plate 41.

[0074] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0075] Working principle: First, fit the carrying tube 33 at one of the extension tubes 6 with the locking tube 7 at the transmission tube 1. Then, rotate the transmission screw 45, and cooperate with the connection between the transmission screw 45 and the displacement push plate 46, so that the displacement push plate 46 can drive the transmission ring 37 to move along the transmission screw 45. Since the limiting light rod 36 is located between the transmission ring 37 and the quick-release ring 34, when the transmission ring 37 moves, it can drive the quick-release ring 34 to move synchronously through the limiting light rod 36, so that it moves out of the carrying tube 33 and moves into the slot 8, forming a preliminary connection between the extension tube 6 and the transmission tube 1.

[0076] At the same time, since the guide plate 43 is connected between the transmission ring 37 and the positioning card plate 40, when the transmission ring 37 is displaced, the positioning card plate 40 can be pulled by the guide plate 43. Since the positioning card plate 40 is supported by the carrying shaft 39, the positioning card plate 40 and the pressing plate 41 can rotate simultaneously under the support of the carrying shaft 39. When the positioning card plate 40 is rotated to a horizontal state, the end of the positioning card plate 40 away from the carrying shaft 39 will be in close contact with one side of the carrying ring 27, such as Figure 1 As shown, the extension pipe 6 and the transmission pipe 1 are stabilized and reinforced;

[0077] During the rotation of the pressing plate 41, the pushing rod 31 can be pressed to transmit the gas inside the gas transmission cylinder 30 to the inside of the deformable airbag 28 through the pushing piece 32, thereby causing the deformable airbag 28 to expand. In conjunction with the connection between the deformable airbag 28 and the rubber strip 29, the gap between the quick-release ring 34 and the slot 8 can be further sealed with the help of the rubber strip 29. Subsequently, the quick-release ring 34 of the next extension tube 6 is moved into the slot 8 of the previous extension tube 6, thereby achieving effective assembly between the two adjacent extension tubes 6, greatly improving the splicing efficiency of the extension tubes 6.

[0078] The subsequent liquid will be transmitted through the transmission pipe 1, and the solid matter in the liquid can be intercepted by the filter screen 2. The intercepted liquid will be discharged to the desired position through multiple extension pipes 6. When the filter screen 2 is seriously clogged, the drainage will be suspended first, and the transmission shaft 16 will be rotated to prompt the transmission worm 17 to turn the matching worm gear 18, thereby driving the hollow shaft 11 to rotate. Under the connection between the adjusting screw 12 and the hollow shaft 11, the adjusting screw 12 can move the knocking plate 14 into the interior of the transmission pipe 1 under the limit of the linkage rod 22. Then, the knocking plate 14 is driven to rotate by the cleaning shaft 13. When the knocking plate 14 rotates to contact the filter screen 2, as the knocking plate 14 continues to rotate, it can knock on the filter screen 2, prompting the filter screen 2 to shake, so as to shake off the solid matter attached to the filter screen 2;

[0079] When the knocking plate 14 moves downward, the downward movement force of the knocking plate 14 can be transmitted through the linkage rod 22, prompting the linkage seat 26 to push the linkage bar 24, thereby driving the blocking plate 21 to flip under the support of the bearing rod 20, thereby releasing the blockage of the bottom end of the sewage pipe 4, allowing the shaken solid matter to be discharged from the transmission pipe 1 through the sewage pipe 4, thereby ensuring the working effect of the filter screen 2;

[0080] After cleaning is completed, the transmission shaft 16 is rotated in the opposite direction, prompting the adjusting screw 12 to drive the knocking plate 14 to move into the storage tube 3. At the same time, the sewage pipe 4 can be blocked with the help of the linkage rod 22 to prevent the liquid from being discharged from the sewage pipe 4 during subsequent liquid transmission. In addition, in conjunction with the setting of the sealing plate 23, after the knocking plate 14 moves into the storage tube 3, the bottom end of the storage tube 3 can be blocked by the sealing plate 23 to prevent liquid from entering the storage tube 3.
