The rotating hole 15 can transfer the supporting force of the connecting seat 3 to the rotating seat 4 through the rotating shaft 17 to ensure the stability of the rotation of the rotating seat 4. The rotating groove 18 has a limiting effect on the rotating plate 19. When the positioning plate 13 is inserted into the positioning groove 14, the positioning groove 14 transfers the positioning effect of the connecting seat 3 to the sliding seat 12 through the positioning plate 13, and the sliding seat 12 transfers the positioning effect to the rotating seat 4, thereby ensuring that the rotating seat 4 does not rotate, and the positioning plate 13 realizes the function of positioning the rotating seat 4; and

[0029] The handrail tube 5 is fixedly connected to the top of the rotating seat 4, and a U-shaped tube 7 is slidably connected inside the handrail tube 5. The U-shaped tube 7 is provided with a plurality of fixing holes 21, and a C-shaped buckle 6 is slidably connected inside the fixing hole 21. The U-shaped tube 7 can extend the width of the handrail tube 5, and the C-shaped buckle 6 fixes the U-shaped tube 7 in the handrail tube 5. The fixing holes 21 provided on the U-shaped tube 7 ensure that the C-shaped buckle 6 fixes the U-shaped tube 7. In actual use, the surface of the handrail tube 5 can be wrapped with a protective cover such as a sponge in the prior art, and the protective cover further provides convenience for people with physical disabilities, thereby improving the use effect of the handrail tube 5.

[0030] In some specific embodiments, the spring 10 is located between the rotating seat 4 and the sliding seat 12, and the upper and lower ends of the spring 10 are fixedly connected to the rotating seat 4 and the sliding seat 12 respectively. The sliding seat 12 is slidably connected in the sliding groove 11. The spring 10 is always in a stretched state. The spring 10 pulls the sliding seat 12 downward, and the sliding seat 12 is stably located in the sliding groove 11. The sliding seat 12 inserts the positioning plate 13 into the positioning groove 14 to ensure that the positioning plate 13 will not be automatically detached from the positioning groove 14 due to vibration, thereby improving the use effect of the sliding seat 12.

[0031] In some specific implementation schemes, the bottom end of the slide 12 is fixedly connected to the positioning plate 13, the side end of the slide 12 is fixedly connected to a pull rod 9, and the center of the pull rod 9 is fixedly connected to a handle 8. The pull rod 9 can connect the two slides 12 to ensure the stability of the overall structure. At the same time, the handle 8 on the pull rod 9 is convenient for the user to pull the pull rod 9 upward. Pulling the pull rod 9 can drive the slide 12 to move upward in the slide groove 11, thereby disengaging the positioning plate 13 from the positioning groove 14.

[0032] In some specific embodiments, an H-type tube connector 2 is fixedly connected to the bottom end of the rotating plate 19, a threaded hole 20 is opened inside the H-type tube connector 2, and a leg tube 1 is threadedly connected inside the threaded hole 20. When the height of the H-type tube connector 2 is adjusted, the H-type tube connector 2 is rotated, and the H-type tube connector 2 moves upward on the leg tube 1. The H-type tube connector 2 drives the rotating plate 19 to rotate in the rotating groove 18, and the rotating plate 19 drives the connecting seat 3 to move upward, and the connecting seat 3 drives the rotating seat 4 to move upward.

[0033] In some specific implementation schemes, the C-shaped buckle 6 is snap-connected with the side end of the handrail tube 5 and the side end is away from the rotating seat 4. A plurality of fixing holes 21 are evenly distributed inside the U-shaped tube 7 along the horizontal direction of the U-shaped tube 7. The distribution of the fixing holes 21 ensures that the U-shaped tube 7 can be fixed in different positions after adjustment.

[0034] In some specific embodiments, the rotating shaft 17 is threadedly connected with a nut 16 at the side end away from the rotating seat 4. The nut 16 can position the connecting seat 3 to ensure that the rotating seat 4 and the connecting seat 3 are connected together and the rotating seat 4 will not fall off the connecting seat 3.

[0035] In order for those skilled in the art to better understand the working principle of the embodiments of the present invention, the following is an explanation in conjunction with specific application scenarios:

[0036] The user adjusts the height according to actual needs, rotates the H-tube connector 2, and the H-tube connector 2 moves upward on the leg tube 1. The rotation of the H-tube connector 2 drives the rotating plate 19 to rotate in the rotating groove 18, and the rotating plate 19 drives the connecting seat 3 to move upward, and the connecting seat 3 drives the rotating seat 4 to move upward. At the same time, the user can pull the U-tube 7, and the U-tube 7 slides in the handrail tube 5, and inserts the C-shaped buckle 6 into the fixing hole 21. The U-tube 7 can extend the width of the handrail tube 5, and the C-shaped buckle 6 fixes the U-shaped tube 7 in the handrail tube 5. The fixing hole 21 opened on the U-tube 7 ensures that the C-shaped buckle 6 fixes the U-shaped tube 7. In actual use, the surface of the handrail tube 5 can be wrapped with a protective cover such as a sponge in the prior art. The protective cover further provides convenience for people with physical inconvenience, thereby improving the use effect of the handrail tube 5. The distribution of the fixing holes 21 ensures that the U-tube 7 is fixed in different positions after adjustment.

[0037] When the disabled person gets out of bed, the handrail tube 5 can be flipped over, and the user controls the handle 8 to pull the pull rod 9 upwards, which can drive the slide 12 to move upwards in the slide slot 11, thereby disengaging the positioning plate 13 from the positioning slot 14. At the same time, the slide 12 pulls the spring 10 upwards, and the spring 10 is always in a stretched state. The spring 10 pulls the slide 12 downwards, flips the rotating seat 4, and the rotating seat 4 rotates at the side end of the connecting seat 3. The rotating seat 4 drives the handrail tube 5 to rotate, thereby realizing the flipping effect of the handrail tube 5, improving The applicability of the bedside handrail is improved. When the pull rod 9 is not pulled upward, the slide 12 is stably located in the slide groove 11, and the slide 12 inserts the positioning plate 13 into the positioning groove 14 to ensure that the positioning plate 13 will not automatically detach from the positioning groove 14 due to vibration, thereby improving the use effect of the slide 12. The positioning groove 14 transfers the positioning effect of the connecting seat 3 to the slide 12 through the positioning plate 13, and the slide 12 transfers the positioning effect to the rotating seat 4, thereby ensuring that the rotating seat 4 will not rotate. The positioning plate 13 realizes the function of positioning the rotating seat 4.
