[0035] The working principle of a rotating chair provided by the utility model is as follows: when the adjustment device 2 needs to be installed on the backboard 5, the connecting plate 205 is fixed to the backboard 5 using the screw 206, and then the cushion 202 is placed on the connecting plate 201, on one side of the backboard 5. When the cushion 202 is placed on the connecting plate 201, the threaded cylinder 203 installed on the cushion 202 can be aligned with the angle of the rotating rod 204, and then the connecting block 207 can be rotated. The rotation of the connecting block 207 will drive the rotating rod 204 to move until the rotating rod 204 is connected to the threaded cylinder 203 by rotating the rotating rod 204, and then the cushion 202 can be fixed on the connecting plate 201, on one side of the backboard 5, and then the cushion 202 can be fixed on the connecting plate 201, on one side of the backboard 5. 202 is used to reduce the pain caused by the contact between the user's back and the backrest 5. When the connecting block 207 is used to rotate the screw 206, the anti-slip groove 208 on the connecting block 207 can increase the friction between the user's hand and the connecting block 207, thereby increasing the speed of rotating the connecting block 207. When the soft cushion 202 is in contact with the connecting plate 201, the metal plate 210 installed on the soft cushion 202 will be adsorbed by the magnetic block 209 on the connecting plate 201. The adsorption of the magnetic block 209 and the metal plate 210 can improve the contact stability between the soft cushion 202 and the connecting plate 201. The arc-shaped connecting plate 201 can better wrap the soft cushion 202, thereby improving the contact stability between the connecting plate 201 and the soft cushion 202.

[0036] When the damaged foot pad 6 needs to be replaced, the adjusting rod 36 is pressed in the direction of the connecting ring 37 to press the adjusting rod 36 out of the connecting groove 35, and the connecting ring 37 is rotated in the adjusting rod 36 to rotate the connecting ring 37 out of the adjusting rod 36. At this time, the adjusting rod 36 can be pulled away from the connecting ring 37 until the fixing effect of the adjusting plate 31 is released by pulling the adjusting rod 36 in the connecting groove 35. Then, the adjusting plate 31 and the foot pad 6 can be removed from the connecting tube 33, and then a new foot pad 6 can be inserted through the adjusting plate 31 and the contact block. 34 is connected, and then the connecting ring 37 is used to connect with the adjusting rod 36, so that the new foot pad 6 can be installed on the lifting device 4. When the adjusting rod 36 needs to be pressed, the force block 39 installed on the adjusting rod 36 can be used to press the adjusting rod 36. The force block 39 can improve the pressing efficiency of the adjusting rod 36. When the adjusting plate 31 is connected to the contact block 34, the auxiliary plate 32 installed on the adjusting plate 31 can increase the speed of the connection between the adjusting plate 31 and the contact block 34, thereby improving the efficiency of the connection between the adjusting plate 31 and the contact block 34.
