A positioning card 7 is fixedly connected to the left end of the slide rod 6. The positioning card 7 is used to fix the splicing tube 9. The cooperation of the limit block 5 and the slide rod 6 can make the positioning card 7 and the central axis of the quick-release sleeve 3 on the same straight line. A tightening ring 8 is sleeved on the outside of the expansion joint 2 and located on the inside of the quick-release sleeve 3. A splicing tube 9 is sleeved on the inside of the expansion joint 2. The tightening ring 8 is used to tighten the expansion joint 2 to ensure a firm connection between the expansion joint 2 and the splicing tube 9.

[0027] For further information, see Figure 1 , Figure 2 and Figure 3The inner diameter of the quick-install sleeve 3 is equal to the outer diameter of the expansion joint 2. A through hole 10 is provided on the outer side of the quick-install sleeve 3. A notch 11 is provided on the outer side of the quick-install sleeve 3 and on the left side of the through hole 10. A groove 12 is provided on the inner side of the quick-install sleeve 3 and opposite to the through hole 10. The groove 12 is adapted for use with the tightening ring 8. During use, the tightening ring 8 is inserted into the interior of the quick-install sleeve 3 from the through hole 10 provided on the outer side of the quick-install sleeve 3, so that the tightening ring 8 is embedded in the inner side of the quick-install sleeve 3. The end of the hose body 1 away from the expansion joint 2 is inserted into the groove 12, and then the end of the hose body 1 away from the expansion joint 2 is inserted from the left end of the quick-release sleeve 3 until the expansion joint 2 is sleeved into the inside of the quick-release sleeve 3. At this time, the tightening ring 8 is located on the outside of the expansion joint 2.

The fixed card 701 is fixedly connected to the left end of the sliding rod 6, and the rotating card 702 is rotatably connected to the top of the fixed card 701. The fixed card 701 and the rotating card 702 are used in combination to facilitate the placement and clamping of the splicing pipe 9. The two sets of inner pads 703 are respectively fixedly connected to the inner sides of the fixed card 701 and the rotating card 702. The inner pad 703 can increase the friction force and prevent the splicing pipe 9 from moving. The auxiliary handle 704 is fixedly connected to the top of the rotating card 702. The auxiliary handle 704 is used to facilitate the pulling of the fixed card 701. The fixed card 701 and the rotating card 702 are both smaller than a semicircle, which can ensure that the splicing pipe 9 is more firmly clamped. The inner diameters of the fixed card 701 and the rotating card 702 are equal to the outer diameter of the splicing pipe 9. The rear ends of the fixed card 701 and the rotating card 702 are fixedly connected by fastening bolts 14.

[0032] For further information, see Figure 5 A supporting short tube 15 is sleeved on the inner side of the splicing tube 9, and a fastening groove 16 is opened on the outer side of the supporting short tube 15. The tightening ring 8 is adapted for use with the fastening groove 16. The supporting short tube 15 is used to support the splicing tube 9 to prevent the splicing tube 9 from being deformed under pressure. The fastening groove 16 facilitates the tightening ring 8 to tighten the splicing tube 9 to prevent the splicing tube 9 from falling off.

[0033] The utility model workflow:

[0034] During use of the utility model, the tightening ring 8 is first inserted into the interior of the quick-release sleeve 3 from the through hole 10 opened on the outside of the quick-release sleeve 3, so that the tightening ring 8 is embedded in the groove 12 on the inside of the quick-release sleeve 3, and then the end of the hose body 1 away from the expansion joint 2 is inserted from the left end of the quick-release sleeve 3 until the expansion joint 2 is sleeved into the interior of the quick-release sleeve 3. At this time, the tightening ring 8 is located on the outside of the expansion joint 2, and the supporting short tube 15 is sleeved onto the inner side of the splicing tube 9, so that the right end of the supporting short tube 15 is flush with the right end of the splicing tube 9, and then the splicing tube 9 is placed on the inner side of the fixing card 701, and the right end of the splicing tube 9 exceeds the right end of the fixing card 701, and the exceeding length is equal to the inner length of the expansion joint 2, and then the rotating card 702 is closed, and then the rotating card 702 and the fixing card 701 are tightened by the fastening bolt 14, and then the sliding rod 6 fixedly connected to the right end of the fixing card 701 is inserted into the inner side of the two sets of limit blocks 5. , and then use both hands to respectively move the auxiliary handle 704 and the auxiliary tube 4 together, the auxiliary handle 704 drives the fixing card 701 to move, and when the fixing card 701 moves, it drives the splicing tube 9 to move, and when the auxiliary tube 4 moves, it drives the quick-install sleeve 3 to move, and when the quick-install sleeve 3 moves, it drives the expansion joint 2 to move. Under the cooperation of the sliding rod 6 and the limiting block 5, the central axes of the splicing tube 9 and the expansion joint 2 are kept in the same straight line, so that the splicing tube 9 and the expansion joint 2 can be quickly connected. When the expansion joint 2 and the splicing tube 9 are spliced, the tightening ring 8 is tightened to make the splicing between the expansion joint 2 and the splicing tube 9 more firm. The supporting short tube 15 supports the splicing tube 9 to prevent the splicing tube 9 from being compressed and deformed. The fastening groove 16 can prevent the splicing tube 9 from falling off after the tightening ring 8 is tightened. During the process, there is no need to calibrate the position of the splicing tube 9 and the hose body 1 first, which makes the splicing process convenient and fast, and increases practicality.
