[specific embodiment]

Please refer to shown in Fig. 1,2,3, this utility model is the bending structure on a kind of wheelchair handgrip, in the present embodiment, wheelchair handgrip bending structure can be applicable on the wheelchair skeleton 10, allow the operator can fold the handle pipe 131 of wheelchair skeleton 10, and the shared spatial area of whole wheelchair is reduced.This structure comprises a wheelchair skeleton 10 and a bending structure 20, and this bending structure 20 can comprise a pedestal 3 one 4 and one trip 5 of helping pull a cart.

In the present embodiment, wheelchair skeleton 10, by a left frame 11, a handgrip 13, left side frame 12, handgrip 13, take portion 14, pedal frame 15, wheels 16 and fold the group 17 form, wherein this left frame 11 and left side frame 12 can make left and right

bogie side frame

11,12 draw close folding towards the centre by folding group 17 foldings, form a wheelchair skeleton 10 that folds.
