[0024] Working principle: When using the present invention, firstly, the support plate 1 is installed on the seat through the mounting hole 3 on the mounting block 2. When the height of the armrest body 26 needs to be adjusted, the armrest body 26 is pulled to make the connecting rod 5 slide up and down along the supporting rod 4 to achieve the height adjustment of the armrest body 26. The armrest body 26 is rotated, and the mounting seat 23 in the second mounting groove 21 on the base 20 in the receiving groove 27 and the rotating wheel 25 in the third mounting groove 24 on the mounting seat 23 are rotated. The rotating wheel 25 is fixed on the connecting plate 19, so that the armrest body 26 is adjusted in the horizontal direction with one end of the connecting plate 19 as the center. The armrest body 26 is rotated to make the connecting seat 7 rotate on the fixing seat 6, so that the armrest body 26 can be rotated on the horizontal plane. The armrest body 26 is movable to achieve the purpose of adjusting the horizontal direction of the armrest body 26. By pressing or pulling up one end of the armrest body 26, the armrest body 26 drives the rotating cover 14 to rotate on the connecting seat 7 through the connecting plate 19. The rotating cover 14 rotates on the connecting seat 7 through the connecting column 12, the rotating shaft 13, and the connecting block 15, and pushes the block 10 out through the spring 9 in the first mounting groove 8, and cooperates with the three limiting grooves 18 on the positioning block 17 on the inner wall of the rotating cover 14 to limit, so as to achieve three gears of inclination adjustment. When the limit is exceeded, the boss 11 falls into the groove 16, causing the block 10 to be unlocked, and the armrest body 26 is reset. The utility model is a left-side armrest, and the right-side armrest structure is symmetrical with the left-side armrest and has the same function. The left and right armrests are installed and used in groups.
