Then the sliding plate 5 can slide on the surface of the support rod 2 to complete the up and down adjustment. Then hold the armrest body 19 and pull it forward to make the adjustment block 17 slide inside the fixing plate 15 through the adjustment groove 16, and the armrest body 19 can complete the front and back adjustment effect, thus avoiding the situation that the existing office chair has a poor use effect due to the inconvenient arm support of the user when facing the height requirements of different users because its armrest is directly fixed on the sides of the seat cushion and the backrest. The fixing grooves 3 are evenly distributed at the front and rear ends on the left side of the support rod 2. The sliding plate 5 is slidably connected with the support block 1. The chutes A6 are symmetrically distributed at the front and rear ends on the left side of the sliding plate 5, which is more convenient for the sliding plate 5 to slide and prevents the situation that the sliding plate 5 cannot continue to slide because the sliding plate 5 is stuck by the support block 1 during use.

The clamping blocks 11 are symmetrically distributed at the front and rear ends on the right side of the clamping plate 10. The clamping blocks 11 are slidably connected with the chute A6, the clamping blocks 11 are slidably connected with the sliding plate 5, and the clamping blocks 11 are slidably connected with the support rod 2, which is more convenient for the clamping blocks 11 to slide.Prevent the situation where the clamping block 11 cannot continue to slide because the clamping block 11 is stuck by the sliding plate 5 or the support rod 2 during use. The baffle 12 is slidably connected to the fixed block 8. One end of the spring 13 away from the baffle 12 is fixedly installed on the inner wall of the fixed block 8. The spring 13 is slidably connected to the sliding rod 9 and the fixed block 8. The pulling block 14 is slidably connected to the fixed block 8, which makes it more convenient for the baffle 12 and the spring 13 to slide, and avoids the situation where the baffle 12 and the spring 13 cannot continue to slide because they are stuck by the fixed block 8 during use.

[0035] As Figures 1-3 As shown in Figure 5, the top end of the adjusting block 17 is fixedly installed with an installation block 20. An installation hole A21 is opened on the side of the installation block 20. An installation groove 22 is opened at the bottom end of the armrest body 19.

When the clamping rod 24 completely slides out of the inside of the installation block 20 and the armrest body 19, then the armrest body 19 can be pinched and lifted upwards, so that the armrest body 19 slides out of the surface of the installation block 20 through the installation groove 22 for replacement, thereby preventing the situation where the armrest body 19 cannot be replaced because no disassembly structure is designed when replacement is needed after long-term use. The installation block 20 is slidably connected to the armrest body 19, the installation block 20 is slidably connected to the installation groove 22, the clamping rod 24 is slidably connected to the armrest body 19, the clamping rod 24 is slidably connected to the installation block 20, and the soft plug 25 is slidably connected to the armrest body 19, which makes it more convenient for the clamping rod 24 to slide and avoids the situation where the clamping rod 24 cannot continue to slide because it is stuck by the armrest body 19 or the installation block 20 during use.

[0036] At least one of the above embodiments of the present utility model can at least achieve that when it is necessary to adjust the height of the armrest body 19 during use, first press the pull block 14 to make the sliding rod 9 slide to the left inside the fixed block 8, then slide to the left inside the sliding plate 5 through the chute B7, and slide to the left inside the support rod 2 through the sliding groove 4 again. When the sliding rod 9 drives the clamping block 11 through the clamping plate 10 to slide out of the inside of the support rod 2 through the fixed groove 3 and completely slide into the inside of the sliding plate 5 through the chute A6, then hold the fixed plate 15 and lift it upward to make the sliding plate 5 slide upward on the surface of the support rod 2, and the sliding rod 9 slides inside the support rod 2 through the sliding groove 4. When the bottom end of the sliding plate 5 breaks away from the bottom end of the support block 1 and the armrest body 19 slides to the required position, the pull block 14 can be released. Under the elastic force of the spring 13 itself, the sliding rod 9 can be driven to slide to the right through the baffle 12, and the clamping block 11 can be driven to slide to the right through the clamping plate 10. When the clamping block 11 slides out of the inside of the sliding plate 5 through the chute A6 and completely slides into the inside of the support rod 2 through the fixed groove 3, then pinch the armrest body 19 and push it forward to make the adjusting block 17 slide inside the fixed plate 15 through the adjusting groove 16. When the adjusting block 17 slides to the required position, the soft pad 18 can firmly clamp the adjusting block 17 inside the fixed plate 15 through the adjusting groove 16, so that the armrest body 19 can better meet the needs of different users. And after long-term use, when it is necessary to replace the armrest body 19, it can be pulled outward through the stop block 26 to make the clamping rod 24 slide inside the armrest body 19 through the mounting hole B23 and slide inside the mounting block 20 through the mounting hole A21.
