[0021] As Figures 1 to 4 shown, the height adjustment component includes a rotating ring 4, a limiting rod 5, a moving rod 6, a limiting hole 7, a first compression spring 8, an inserting rod 9 and an inserting hole 10. The top end of the bottom rod 1 is rotatably installed with a rotating ring 4. The outer side of the rotating ring 4 is symmetrically and fixedly installed with limiting rods 5. The outer side of the rotating ring 4 is symmetrically slidably installed with moving rods 6. The moving rods 6 are provided with limiting holes 7 corresponding to the positions of the limiting rods 5. The limiting holes 7 are slidably connected with the limiting rods 5. The outer side of the limiting rod 5 is sleeved with a first compression spring 8. One end of the first compression spring 8 is fixedly connected with one side of the moving rod 6. The other end of the first compression spring 8 is fixedly connected with one end of the rotating ring 4. The top end of the moving rod 6 is fixedly installed with an inserting rod 9. The outer side of the lifting rod 2 is equidistantly provided with inserting holes 10. The inserting holes 10 are slidably connected with the inserting rod 9.

[0022] By pulling the moving rod 6 to slide along the limiting rod 5, the inserting rod 9 is slid out of the inserting hole 10. At this time, the first compression spring 8 is in a compressed state. Then rotate the rotating ring 4 to rotate the inserting rod 9 out of the vertical positions of several inserting holes 10. Then adjust the height between the bottom rod 1 and the lifting rod 2. Then rotate the rotating ring 4 in the reverse direction to rotate the inserting rod 9 to the vertical positions of several inserting holes 10. Under the pushing of the first compression spring 8 on the moving rod 6, the inserting rod 9 will be driven to insert into the inserting holes 10 at different heights, so as to adjust the height of the handrail frame.

[0023] As Figures 1 to 4As shown, the height adjustment assembly further includes a limit groove 11 and a limit ring 12. The top end of the bottom rod 1 is provided with a limit groove 11, and the inner ring of the swivel ring 4 is provided with a limit ring 12 corresponding to the position of the limit groove 11. The limit ring 12 is rotatably connected to the limit groove 11.

[0024] When the swivel ring 4 is rotated, the limit ring 12 will rotate inside the limit groove 11 to limit the position of the swivel ring 4.

[0025] As Figures 1 to 4 shown, the angle adjustment assembly includes a support rod 13, a sliding hole 14, a sliding rod 15, a second compression spring 16 and a positioning hole 17. The two sides of the rotating rod 3 are symmetrically and rotatably installed with support rods 13 through pin shafts. The bottom end of the support rod 13 is provided with a sliding hole 14, and a sliding rod 15 is slidably installed inside the sliding hole 14. One end of the sliding rod 15 is sleeved with a second compression spring 16. One end of the second compression spring 16 is fixedly connected to the end of the sliding rod 15, and the other end of the second compression spring 16 is fixedly connected to the support rod 13. The top end of the lifting rod 2 is equidistantly provided with positioning holes 17, and the positioning holes 17 are slidably connected to the sliding rod 15.

[0026] Drive the sliding rod 15 to slide out of the positioning hole 17, and then rotate the rotating rod 3. At this time, the sliding rod 15 at the bottom of the support rod 13 will slide inside the guide groove 18, and the angle between the rotating rod 3 and the lifting rod 2 will change. Then, the sliding rod 15 is slid into the positioning hole 17 through the second compression spring 16 to adjust the angle between the rotating rod 3 and the lifting rod 2.

[0027] As Figures 1 to 4 shown, guide grooves 18 are provided at the corresponding positions of the opposite top ends of the lifting rod 2 corresponding to a plurality of positioning holes 17.

[0028] When the rotating rod 3 is rotated, the sliding rod 15 at the bottom of the support rod 13 will slide inside the guide groove 18 to limit the relative position between the sliding rod 15 and the positioning hole 17.

[0030] Press down the triangular ring 19, and the triangular ring 19 can facilitate the sliding rod 15 to slide out of the inside of the sliding hole 14 by extruding the extrusion inclined groove 20.

[0031] The present invention provides a deformable tiller handrail device, and the specific working principle is as follows:

[0032] When the device is in use and the height of the armrest is adjusted, by pulling the moving rod 6 to slide along the limiting rod 5, the inserting rod 9 is slid out of the inserting hole 10. At this time, the first compression spring 8 is in a compressed state. Then, the rotating ring 4 is rotated to rotate the inserting rod 9 out of the vertical positions of several inserting holes 10. Then, the height between the bottom rod 1 and the lifting rod 2 is adjusted. Then, the rotating ring 4 is rotated in the reverse direction to rotate the inserting rod 9 to the vertical positions of several inserting holes 10. Under the pushing of the first compression spring 8 on the moving rod 6, the inserting rod 9 will be driven to insert into the inserting holes 10 at different heights, so as to adjust the height of the armrest;

[0033] When adjusting the angle between the rotating rod 3 and the lifting rod 2, the triangular ring 19 is pressed down. The triangular ring 19 will squeeze the inclined slot 20, and drive the sliding rod 15 to slide inside the sliding hole 14. At this time, the second compression spring 16 is in a stretched state, and the sliding rod 15 will be driven to slide out of the positioning hole 17. Then, the rotating rod 3 is rotated. At this time, the sliding rod 15 at the bottom of the support rod 13 will slide inside the guide slot 18, and the angle between the rotating rod 3 and the lifting rod 2 will change. Then, the sliding rod 15 is slid into the positioning hole 17 by the second compression spring 16, so as to adjust the angle between the rotating rod 3 and the lifting rod 2.
