A screw 6 is threadedly connected to the inside of the connecting seat 5, and a collar 7 is rotatably connected to the outside of the screw 6. A support rod 8 is fixedly connected to the outside of the collar 7, and a screw 9 is fixedly connected to the end of the support rod 8 away from the collar 7. A sleeve 10 is rotatably connected to the end of the screw 9 away from the support rod 8. The end of the sleeve 10 away from the screw 9 is rotatably connected to another set of collars 7. A wear-resistant strip 19 is fixedly connected to the outside of the outer layer 3. A plurality of wear-resistant strips 19 are provided. The wear-resistant strips 19 are made of high manganese steel. When the hose 1 needs to be installed and needs to be bent at a turning point, the hose 1 can be installed by the flexible hose 1 itself. The softness is such that the hose 1 can be fitted to the wall, and by rotating the sleeve 10, the screw rod 9 can slide inside the sleeve 10, thereby driving the support rod 8 to move in the direction of the sleeve 10, thereby realizing that one end of the hose 1 is in a bent state and the bending angle is fixed. At the same time, when the hose 1 is bent, the collar 7 can be driven to swing outside the screw rod 6, so that the flexibility of the support rod 8 when moving toward the sleeve 10 is greatly improved. At the same time, a group of gaskets are also arranged outside the screw rod 6, and the collar 7 can be fixed by rotating the gaskets. The wear-resistant strip 19 can protect the surface of the hose 1, thereby avoiding as much as possible the situation in which the outer surface of the rubber hose 1 is damaged due to friction during long-term use of the hose 1.

[0024] For further information, see Figure 1 and Figure 2 In this embodiment, an internal thread is provided inside the sleeve 10, and the screw rod 9 is connected to the internal thread of the sleeve 10. A silicone pad is coated on the inner wall of the fixed sleeve 4. When the hose 1 and the fixed sleeve 4 are in contact with each other through the silicone pad, the friction between the two will be greatly improved, effectively preventing the fixed sleeve 4 from being offset outside the hose 1.

[0025] For further information, see Figure 1 ,Figure 3 and Figure 4 In this embodiment, the fixing sleeve 4 is composed of a first semi-arc frame 401 and a second semi-arc frame 402. A card slot 403 is provided at the bottom of the first semi-arc frame 401. A card block 404 is fixedly connected to the bottom of the second semi-arc frame 402 at a position corresponding to the card slot 403. The outside of the card block 404 is fixedly connected to a plug column, which extends to the outside of the card slot 403. The top of the first semi-arc frame 401 is fixedly connected to a card column 11. The inside of the card column 11 is respectively provided with an inclined groove 12 and an irregular groove 13. shaped groove 13, a through groove 14 is opened at the top of the second semi-arc frame 402 at a position corresponding to the clamping column 11, a first spring 15 is fixedly connected between the clamping column 11 and the first semi-arc frame 401, and the clamping block 404 is rotated inside the clamping groove 403 to realize that the first semi-arc frame 401 and the second semi-arc frame 402 wrap the hose 1, and the tops of the first semi-arc frame 401 and the second semi-arc frame 402 are connected to each other, so that the clamping column 11 is clamped into the inside of the through groove 14.

[0026] For further information, see Figure 1 , Figure 3 and Figure 4 In this embodiment, the top of the second semi-arc frame 402 is plugged and connected with a pressing column 16, the outer sleeve of the pressing column 16 is provided with a second spring 17, and the bottom end of the pressing column 16 is fixedly connected with a cross plate 18. When the card column 11 is inserted into the interior of the through groove 14, the pressing column 16 is pressed to realize that the pressing column 16 is inserted into the interior of the special-shaped groove 13, and the cross plate 18 will contact the special-shaped groove 13. At the same time, the second spring 17 will release the stored energy to realize that the cross plate 18 and the special-shaped groove 13 are pressed against each other, thereby realizing the connection between the first semi-arc frame 401 and the second semi-arc frame 402. When it is necessary to separate the fixed sleeve 4, by pressing the pressing column 16, the oblique groove 12 is squeezed by the cross plate 18, so that the special-shaped groove 13 releases the fixation of the cross plate 18, and the separation between the first semi-arc frame 401 and the second semi-arc frame 402 is completed, which is convenient and quick.

[0027] For further information, see Figure 1 In this embodiment, the inner wall of the inner core 2 is coated with a corrosion-resistant coating, which is a polyurethane coating. Rubber is filled between the inner core 2 and the outer layer 3. By utilizing the corrosion-resistant coating, the hose 1 can protect the inner core 2 when transporting some corrosive media, thereby avoiding corrosion of the inner core 2 as much as possible.

[0028] In this embodiment, the implementation scenario is specifically as follows: when the hose 1 needs to be installed and needs to be bent at the turning point, the clamping block 404 is rotated inside the clamping groove 403 to realize that the first semi-arc frame 401 and the second semi-arc frame 402 wrap the hose 1, and the tops of the first semi-arc frame 401 and the second semi-arc frame 402 are connected to each other, so that the clamping column 11 is clamped into the interior of the through groove 14, and then the pressing column 16 is pressed to realize that the pressing column 16 is clamped into the interior of the special-shaped groove 13, and the cross plate 18 will contact the special-shaped groove 13, and at the same time the second spring 17 will release the stored energy to realize that the cross plate 18 and the special-shaped groove 13 are pressed against each other, thereby realizing the connection between the first semi-arc frame 401 and the second semi-arc frame 402, and when the fixing sleeve 4 needs to be separated, by pressing the pressing column 16, the inclined groove 12 is squeezed by the cross plate 18, so that the special-shaped groove 13 releases the fixation of the cross plate 18, and the first semi-arc frame 401 is completed. It is convenient and quick to separate from the second semi-arc frame 402, and the hose 1 can be fitted to the wall through the softness of the hose 1 itself, and the screw rod 9 can slide inside the sleeve 10 by rotating the sleeve 10, thereby driving the support rod 8 to move in the direction of the sleeve 10, thereby realizing that one end of the hose 1 is in a bent state and the bending angle is fixed, and at the same time, when the hose 1 is bent, the collar 7 can be driven to swing outside the screw rod 6, so that the flexibility of the support rod 8 when moving toward the sleeve 10 is greatly improved, and the corrosion-resistant coating can be used to protect the inner core 2 when the hose 1 is transporting some corrosive media, thereby minimizing the corrosion of the inner core 2, and the wear-resistant strip 19 can be used to protect the surface of the hose 1, thereby minimizing the damage to the outer surface of the rubber hose 1 due to friction on the outer surface of the hose 1 during long-term use.
