End, the other end is located at the rear end of middle pipe, has two pans on the second hinge seat front end of middle pipe front end, positioned at middle pipe rear end
Second hinge base rear end on have at a pan, head tube on first axle upper two pan of seat and middle pipe before second hinge
Hold two pans by upper connecting rod, two rod hinge connections of lower link into parallelogram sturcutre, lower link rear end bottom sets the
Three hinge seats；The rear chain stay front end of folding stand, which is set on the 4th hinge seat, the 4th hinge seat, preceding pan and rear pan；
Middle pipe interpolation enters seat pipe, and seat pipe can be moved up and down in middle pipe, and be fastened by bunching ring, and the lower end fore-and-aft direction of seat pipe is set
5th hinge seat；The front hinge of the hinge seat of seat pipe lower end the 5th is hinged by front rod with lower link rear end third hinge seat；
The rear iron square hinge of the hinge seat of seat pipe lower end the 5th is hinged by back link with the 4th hinge base rear end pan on rear chain stay.
Second hinge seat is provided with two-stage driving gear, and two-stage driving gear includes foot-operated assembly, the first sprocket wheel, the
Two sprocket wheels, the first chain, the second chain and rear flywheel, foot-operated assembly are fixed on second hinge seat, and the second sprocket wheel is rotatable
On the front end pan for being arranged on the 4th hinge seat on rear chain stay, the first sprocket wheel is fixed on foot-operated assembly, and the first sprocket wheel leads to
The rotation of first the second sprocket wheel of chain-driving is crossed, the rear flywheel that the second sprocket wheel is arranged on by the second chain-driving on trailing wheel is rotated.
The beneficial effects of the invention are as follows：By moving up and down pipe upper locking ring in middle pipe and locking, you can convenient to realize soon
Speed is folded or unfolded bicycle.
