Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] Such as Figure 1-5 As shown, the present invention discloses an adjustable wheelchair armrest mechanism, which includes an armrest 1 and a support mechanism 2 below the armrest 1. The support mechanism 2 includes two support rods, and the number of support rods is at least one. One end of the two support rods is respectively connected to the armrest 1 by screws, and there is a gap at the joint of the screws, so that the front and rear ends of the armrest 1 can independently rotate around the connection point of the two support rods, and the armrest 1 can be adjusted to one end as required High and low. The other ends of the two support rods are connected with a rotating mechanism 3 for adjusting the rotation angle of the supporting rods to drive the armrest 1 to move up and down. The side of the wheelchair is fixed with a slide rail 5 along the depth...
