The periphery of the beam chuck 6 is equipped with braking sleeve 7, and the inner cavity of the braking sleeve 7 is matched with the circular cone of beam chuck 6, the braking
Set 7 is fixedly connected with footrest rack 5, and the top movable of the braking sleeve 7 is connected to hook 8, and the hook 8 is downward along retraction slot 11
Clips 10 are close in extension.
Second embodiment：
Fig. 6, Fig. 7, Fig. 8, Fig. 9, the chair shown in Fig. 10 that fixed footrest rack height can be adjusted, including Foot of chair 1, branch
Support mechanism 2, seat cushion 3, backrest 4 and footrest rack 5, it is down big up small coniform that the support tube 9 of the supporting mechanism 2, which is equipped with shape,
Beam chuck 6, the beam chuck 6 is equipped with three retraction slots 11 penetrated through from top to bottom being evenly distributed, and the beam chuck 6 is equipped with
The periphery of clips 10, the beam chuck 6 is equipped with braking sleeve 7, and the inner cavity of the braking sleeve 7 is matched with the circular cone of beam chuck 6,
The braking sleeve 7 is fixedly connected with footrest rack 5, and the top movable of the braking sleeve 7 is connected to hook 8, and the hook 8 is along contraction
Slot 11, which extends downwardly, is close to clips 10.
3rd embodiment：
Figure 11, Figure 12, Figure 13, Figure 14, the chair shown in figure 15 that fixed footrest rack height can be adjusted, including Foot of chair
1, supporting mechanism 2, seat cushion 3, backrest 4 and footrest rack 5, it is down big up small circle that the support tube 9 of the supporting mechanism 2, which is equipped with shape,
