When the chair is used, when a user needs to rotate the armrest 200, the locking button 210 is pressed to control the angle adjusting locking device to unlock the armrest 200, so that the armrest 200 can rotate along a vertical plane, when the user presses the locking button 210, the locking button 210 compresses the reset spring 240 and is inserted into the button seat 220 in a sliding manner to push the linkage plate 230 to rotate, when the linkage plate 230 rotates, the pull rod 250 is driven to pull the pawl 270 to rotate around the pawl shaft 280 against the elastic force of the torsion spring 290, so that the ratchet 260 connected with the armrest rotating shaft 140 is separated from the pawl 270, at the moment, the user can push the armrest 200 and the rotating positioning block 150 connected with the armrest 200 to rotate between the horizontal arrangement and the vertical arrangement along the vertical plane around the armrest rotating shaft 140, thereby facilitating the user to sit down to the chair body 400 or leave the chair body 400, when the position of the armrest 200 needs to be locked again, only the locking button 210 needs to be released, the compressed reset spring 240 pushes the locking button 210 to reversely move and reset, when the locking button 210 reversely moves, the linkage plate 230 reversely rotates, the pull rod 250 is driven to reversely to move and push the pawl 270 to reset, and simultaneously, the elastic force of the pawl 290 is pushed reversely to move and reset, when the linkage plate 230 reversely rotates, and the pawl 260 is matched with the ratchet 260 to rotate around the rotating shaft, so that the ratchet 260 is meshed with the ratchet shaft to the ratchet shaft 140, and the ratchet 260 can not be meshed with the armrest rotating shaft 140.
When a user rotates the armrest 200 to be vertically arranged, a pair of oppositely arranged overturning planes 170 formed on the outer wall of the rotating positioning block 150 connected with the armrest 200 are aligned with the top and the bottom of the opening 120 respectively, at this time, the user can push the armrest 200 to drive the rotating positioning block 150 and the armrest rotating shaft 140 to rotate around the connecting shaft 130 and disengage from the connecting groove 110 through the opening 120, so that the armrest 200 is rotated to the back of the armrest seat 100 and the seat body 400, thereby freeing up space for the user to move through the side of the seat body 400, when the user needs to reuse the armrest 200, only the armrest 200 is required to be reversely rotated, the armrest 200 drives the rotating positioning block 150 and the armrest rotating shaft 140 to reversely rotate around the connecting shaft 130 and enter the connecting groove 110 through the opening 120, and the armrest 200 can be rotated to the side of the armrest seat 100 and the seat body 400, at this time, the user can press the locking button 210 to control the angle adjusting locking device to unlock the armrest 200 and push the armrest 200 to rotate along the vertical plane to a preset position to limit the user sitting on the seat body 400; when the armrest 200 is not rotated to the vertical arrangement, since the pair of oppositely disposed overturning flats 170 provided on the outer wall of the rotation positioning block 150 are not aligned with the top and bottom of the opening 120, at this time, the pair of oppositely disposed circular arc surfaces 160 of the outer wall of the rotation positioning block 150 are in limit fit with the inner wall of the connecting slot 110, and the user cannot push the rotation positioning block 150 and the armrest rotating shaft 140 to rotate around the connecting shaft 130 out of the connecting slot 110 through the opening 120, thereby limiting that the user can further overturn the armrest 200 to the back surfaces of the armrest seat 100 and the seat body 400 only when rotating the armrest 200 to the vertical arrangement.
In addition, the ratchet 260 is connected with a stop block 300, and a first limiting plate 310 and a second limiting plate 320 are arranged in the handrail 200; the handrail 200 rotates along the vertical plane to be vertically arranged and horizontally arranged, and the first limiting plate 310 and the second limiting plate 320 are respectively used for blocking the stop block 300, so that the first limiting plate 310 and the second limiting plate 320 arranged in the handrail 200 are matched with the stop block 300 for blocking the connection of the ratchet 260, the handrail 200 is ensured to be limited to rotate only between the 90-degree angle between the horizontal arrangement and the vertical arrangement, and the handrail 200 is convenient for a user to use and retract.
