The invention relates to a double-wheel turning mechanism which consists of rectangular slide blocks, a double-front-wheel rotary shaft, a front form shaft sleeve, swing rods, a housing, springs, a slide block line and a fixed pulley. The double-front-wheel turning mechanism is provided with two rectangular slide blocks capable moving mutually and parallelly, each rectangular slide block is connected with the corresponding swing rod through a hinge, the swing rods are inserted into rotary shaft holes formed in two front wheels, the swing rods can freely extend in the rotary shaft holes formed in two front wheels, a front wheel shaft is connected with a front form shaft sleeve, the front form shaft sleeve can rotate around the front form shaft, the swing rods can vertically swing around the hinges in the slide blocks through long grooves formed in the housings of the slide blocks to drive the double-front-wheel rotary shaft to swing around the front fork shaft, the bottoms of the slide blocks are connected with the bottom of the housing through springs and bypass the fixed pulley under the housing through the slide block connecting line to be connected with another slide block, and the upper ends of the two slide blocks are connected with a turning line. The problem that a double-front-wheel bicycle body inclines during turning and accordingly the wheel on one side is away from the ground is solved.
