[0025] refer to Figure 1 and Figure 2As shown, a first positioning plate 5 is fixedly connected to one side of the second mounting ring 33, and a connecting rod 6 is fixedly connected to the inner side of the first positioning plate 5. The connecting rod 6 is supported and fixed by the two first positioning plates 5. A second positioning plate 7 is rotatably connected to the outer side of the connecting rod 6. One end of the second positioning plate 7 is fixedly connected to one side of the first mounting ring 31. The cooperation of the two second positioning plates 7 facilitates the support of the first mounting ring 31, so that the first mounting ring 31 and the second mounting ring 33 can be connected. A fixing bracket 8 is provided on the outer side of the fixing plate 32, and a fixing bolt 9 is provided inside the fixing bracket 8. The cooperation of multiple fixing brackets 8 and fixing bolts 9 facilitates the fixing of the two sets of fixing plates 32, enhancing the connection stability. A first spring 10 is welded to the inner side of the first mounting ring 31, and a limit plate 11 is welded to one end of the first spring 10. The first spring 10 and the limit plate 11 are installed on the inner sides of both the first mounting ring 31 and the second mounting ring 33 to clamp the hose 2, which plays a limiting role and promotes the improvement of connection tightness.

[0026] refer to Figure 1 , Figure 3 and Figure 4 As shown, a fixed frame 12 is fixedly connected to the top of the support 43, and a positioning rod 13 is slidably connected to the inner side of the fixed frame 12. A second spring 14 is provided on the top of the fixed frame 12 and is sleeved on the outer side of the positioning rod 13. One end of the positioning rod 13 is fixedly connected to the bottom of the locking block 44. Through the cooperation of the locking block 44, the positioning rod 13, and the second spring 14, the support sleeve 41 is stably supported. At the same time, when the locking block 44 is pressed down, the restriction on the support sleeve 41 is relaxed, allowing the support sleeve 41 to rotate under the support of the support frame 42. This facilitates the adjustment of the position of the hose 2 as needed, enhancing the flexibility of use. A sealing ring 15 is provided on one side of the hose 2, and an oil pipe body 16 is provided on one side of the sealing ring 15. The sealing ring 15 raises the hose 2 and the oil pipe body 16. To ensure a tight seal and reduce leakage, a sealing sleeve 17 is provided on the inner side of the connecting plate 1. An oil inlet seat 18 is provided at the bottom of the connecting plate 1, and a cylinder 19 is provided at the bottom of the oil inlet seat 18. An oil return seat 20 is provided at the top of the cylinder 19. The oil inlet seat 18 and the oil return seat 20 are respectively connected to the oil inlet and oil return port of the cylinder 19. A sealing sleeve 17 is provided on the inner side of the connecting plate 1, the oil inlet seat 18, and the oil return seat 20. The two connecting plates 1 are fixed to the oil inlet seat 18 and the oil return seat 20 respectively by screws, which facilitates installation and disassembly. The connecting plate 1, hose 2, and oil pipe body 16 installed on the oil inlet seat 18 facilitate the delivery of hydraulic oil to the cylinder 19. The connecting plate 1, hose 2, and oil pipe body 16 installed on the oil return seat 20 facilitate the discharge of hydraulic oil.

[0027] Working principle: In use, one end of the hose 2 is placed between the first mounting ring 31 and the second mounting ring 33. The sealing ring 15 is placed at one end of the hose 2, and the oil pipe body 16 is placed tightly against the other side of the sealing ring 15, so that the hose 2 and the oil pipe body 16 are connected internally and the sealing effect at the connection is ensured, which facilitates the delivery of hydraulic oil. Under the support of the connecting rod 6 and the two first positioning plates 5, the first mounting ring 31 is rotated by the two second positioning plates 7, so that the fixing plate 32 on the first mounting ring 31 contacts the fixing plate 32 on the second mounting ring 33, which encircles and limits the connection between the hose 2 and the oil pipe body 16. The connection is clamped and supported by two sets of first springs 10 and limiting plates 11, which improves the tightness of the connection. The two sets of fixing plates 32 are fixed by the cooperation of multiple sets of fixing brackets 8 and fixing bolts 9, which enhances the connection. The system provides stability and facilitates the installation and fixation of the oil pipe body 16, while also enabling easy disassembly and maintenance. Two connecting discs 1 are connected and fixed to the oil inlet seat 18 and the oil return seat 20 respectively using screws. A sealing sleeve 17 enhances the sealing at the connection point. The support sleeve 41 is supported by the support 43 and two support frames 42. Under the action of the locking block 44, positioning rod 13, and second spring 14, the support sleeve 41 is easily limited and supported, preventing uncontrolled rotation. With the support of the positioning rod 13, second spring 14, and fixing frame 12, pressing down the locking block 44 relaxes the restriction on the support sleeve 41, facilitating control of its rotation under the support of the support frame 42. This allows for adjustment of the hose 2's position as needed, enhancing flexibility in use. The support sleeve 41 supports and limits the hose 2, promoting orderly placement.
