There are two rods 5, and the headrest body 4 is fixedly installed at the top of the two rods 5. Fixing blocks 6 are fixedly connected to both ends of the top surface of the rotating block 3, and the fixing blocks 6 contact the rods 5. A through hole 61 is opened on one side of the fixing block 6, and threaded grooves 51 are opened on the sides of the two rods 5 that are far apart from each other. A screw 7 is threadedly connected inside the threaded grooves 51, and a rotating block 8 is fixedly connected to the end of the screw 7.

[0025] A circular plate 9 is fixedly connected to one side of the rotating rod 2. An auxiliary pointer 10 is fixedly connected to the top of the circular plate 9. An auxiliary line 12 is provided on one side of the mounting base 1. When the auxiliary pointer 10 points to the corresponding auxiliary line 12, the headrest body 4 can be adjusted to the corresponding angle. At the same time, when the auxiliary pointer 10 points to the corresponding auxiliary line 12, the positioning hole 131 can be connected to the corresponding adjustment hole 14, which facilitates the installation of the mounting rod 16. A connecting plate 13 is fixedly connected to the bottom of the circular plate 9. A positioning hole 131 is opened on one side of the connecting plate 13. Multiple adjustment holes 14 are opened on both sides of the mounting base 1. The multiple adjustment holes 14 facilitate the adjustment of the headrest body 4 at multiple angles. The mounting rod 16 is movably connected in the positioning hole 131 and the adjustment hole 14. A toggle rod 15 is fixedly connected to one end of the mounting rod 16. A threaded rod 161 is fixedly connected to the other end of the mounting rod 16. A limit nut 17 is threadedly connected to the threaded part of the threaded rod 161. A backrest 18 is fixedly connected to the bottom surface of the mounting base 1.

[0026] Example 2:

[0027] Please see Figure 1-5 This is the second embodiment of the present invention. Based on the previous embodiment, the two ends of the outer surface of the rotating rod 2 are respectively fixed to the limiting ring block 21. The limiting ring block 21 is rotatably connected to the mounting base 1, which can limit the rotation of the rotating rod 2 and improve the stability of the rotation of the rotating rod 2.

[0028] The screw 7 is movable and connected to the through hole 61 at the smooth rod, and one side of the rotating block 8 contacts one side of the fixed block 6.

[0029] The adjustment hole 14 and the slot 11 are internally connected. The two sides of the rotating block 3 contact the slot 11, which can limit the rotation block 3 and prevent the rotating block 3 from shifting left and right.

[0030] One side of the lever 15 contacts the connecting plate 13, and one side of the limit nut 17 contacts one side of the mounting base 1, which can limit the installation of the mounting rod 16.

[0032] Please see Figure 1-5When using this utility model, if you want to adjust the angle of the headrest body 4, you can unscrew the limiting nut 17, and use the lever 15 to pull out the mounting rod 16, threaded rod 161, adjustment hole 14, and positioning hole 131 to release the limitation on the angle of the headrest body 4. Then, you can rotate the headrest body 4, and the rotating block 3, rotating rod 2, limiting ring block 21, connecting circular plate 9, and auxiliary pointer 10 will rotate accordingly. You can observe the auxiliary pointer 10 and the auxiliary line 12. There are multiple auxiliary lines 12. The angle can be adjusted by the auxiliary pointer 10 pointing to the corresponding auxiliary line 12. After the auxiliary pointer 10 points to the corresponding auxiliary line 12, the positioning hole 131 on the connecting plate 13 can be aligned with the corresponding adjustment hole 14. You can use the lever 15 to adjust the angle of the headrest body 4. The mounting rod 16 and threaded rod 161 are inserted into the positioning hole 131 and the adjustment hole 14, so that one side of the actuating rod 15 contacts the connecting plate 13. Then, the limiting nut 17 is screwed into the threaded rod 161 to limit and fix the inserted mounting rod 16. The installation of the mounting rod 16 can fix the angle of the adjusted connecting plate 13, connecting round plate 9, rotating rod 2, and rotating block 3, thereby limiting and fixing the angle of the adjusted headrest body 4. If you want to disassemble the headrest body 4, you can use the rotating block 8 to screw the screw 7 out of the threaded groove 51 and through hole 61, which can release the limitation on the insertion rod 5. The headrest body 4 and the insertion rod 5 can be moved upward, so that the insertion rod 5 is disengaged from the positioning groove 31, and the headrest body 4 can be disassembled for easy cleaning and maintenance.
