[0035] In the embodiment, the fixed block 17 is arranged to fixedly support the rotating shaft 12, the rotating shaft 12 is fixed, and the limiting blocks 9 at both ends of the rotating shaft 12 rotate around the rotating shaft 12 to adjust the angle of the chair back 15.

[0036] It should be noted that the limiting block 9, the sliding column 10 and the rotating shaft 12 are all cylindrical, and the center lines of the limiting block 9, the sliding column 10 and the rotating shaft 12 coincide, so that the limiting block 9 can rotate smoothly around the rotating shaft 12 after the bolt 13 removes the limiting of the limiting block 9.

[0037] Referring to Figures 1-7 , the top of the stool body 1 is fixedly provided with handrails 18 on both sides, and the bottom of the stool body 1 is fixedly provided with supporting legs 19 on both sides.

[0038] In specific implementation, the supporting legs 19 support the stool body 1, and when the user needs to adjust the body position, the user can hold the handrails 18 on both sides of the stool body 1 to adjust the body to a comfortable position.

[0039] It should be noted that the stool body 1, the outer stool 2, the chair back 15, the handrails 18 and the supporting legs 19 are all made of wood, and the wooden chair does not emit harmful substances, and the wood is renewable and does not harm the environment. At the same time, the wooden chair can also improve the indoor air quality, absorb carbon dioxide and release oxygen, which helps to purify the air. The wooden chair has a longer service life than other materials such as plastic chairs, and the wooden chair has a variety of style choices, which can add natural beauty to the home. Its warm touch and natural texture make people feel more comfortable. At the same time, the design of the wooden chair also often focuses on ergonomics, which can effectively relieve the pressure of the body.

[0040] Working principle: before adjusting the angle of the chair back 15, first rotate the outer stool 2 attached to the bottom of the stool body 1 by 90 degrees, then pull down the outer stool 2 to stretch the tension spring 5, then continue to rotate the outer stool 2 by 90 degrees, so that the outer stool 2 is in the same horizontal plane as the stool body 1. Under the elastic action of the tension spring 5, one end of the outer stool 2 will be attached to one end of the stool body 1, and the clamping block 6 will be inserted into the clamping groove 7.

[0041] Then press the sliding column 10 to make the bolt 13 disengage from the contact with the insertion slot 14, then rotate the chair back 15 by a certain angle, release the sliding column 10, and the bolt 13 will be inserted into another insertion slot 14 under the action of the compression spring 11, so as to adjust the angle of the chair back 15. By providing a plurality of insertion slots 14, the angle adjustment range of the chair back 15 is wider.
