The two groups of armrest rotation mechanisms 2 are arranged on both sides of the seat body 1. By pinching the two groups of bullet blocks 28 at the same time, the two groups of bullet blocks 28 are separated from the two groups of circular holes 27. The two groups of bullet blocks 28 are respectively subjected to pressure on the small springs 214 connected thereto, so that the two groups of small springs 214 are compressed. At this time, the two groups of small springs 214 are compressed. The spring blocks 28 move into the two groups of mounting grooves 213 respectively. At this time, the support plate 21 is slightly pulled upward, and the elastic effect caused by the large spring 29 recovers the compression deformation, driving the inner sleeve 25 and the connecting disc 26 to move upward. When the limit gear 23 is completely disengaged from the engaging tooth groove 212, the support plate 21 is rotated to an angle suitable for the hand shaft, and then the support plate 21 is pressed downward. At this time, the two groups of small springs 214 recover the compression deformation until the two groups of spring blocks 28 are engaged in the other two groups of round holes 27, thereby completing the adjustment of the horizontal rotation angle of the armrest.

At this time, the two groups of small springs 214 are subjected to force compression, and the two groups of bullet blocks 28 move into the two groups of mounting grooves 213 respectively. At this time, the support plate 21 is slightly lifted upward, and the elastic effect generated by the large spring 29 recovers the compression deformation, driving the inner sleeve 25 and the connecting disc 26 to move upward. When the limit gear 23 is completely separated from the engaging tooth groove 212, the support plate 21 is rotated to an angle suitable for the hand shaft, and then the support plate 21 is pressed downward. At this time, the two groups of small springs 214 recover the compression deformation until the two groups of bullet blocks 28 are engaged in the other two groups of circular holes 27, so that the horizontal rotation angle of the armrest can be quickly adjusted.
