Further, the upper front fork seat is in a clamp shape, and the upper end of the cylinder body of the lower front fork seat is held by the upper front fork seat and fixed by a screw.
Further, the lower end of the lower front fork seat is rotatably hinged to two opposite hinged ends of the front fork leg through a locking screw B, the lower end of the shock absorber is rotatably hinged to the other two opposite hinged ends of the front fork leg through a locking screw C, the upper end of the shock absorber is rotatably hinged to the upper front fork seat through a locking screw A, and when an obstacle is met, the front fork leg rotates around the lower front fork seat to lengthen the wheelbase of the axle center of the front wheel and the axle center of the rear wheel.
The lower end of the lower front fork seat and the lower end of the shock absorber are rotatably hinged to the hinged ends of the front fork legs, the upper front fork seat is fixedly connected with the upper end of the lower front fork seat, the upper end of the shock absorber is rotatably hinged to the upper front fork seat, when an obstacle is met, the front fork legs of the bicycle enable the front fork legs to squeeze the shock absorber through hinged rotation with the lower front fork seat, and compared with the traditional shock absorbing front fork, the shock absorbing front fork has the advantages that the front fork legs move forwards and upwards by taking the lower front fork seat as the center during shock absorption, so that the axle distance between the axle center of a front wheel and the axle center of a rear wheel is prolonged, and the stability and the safety of riding can be greatly increased. The utility model has simple structure, simple and convenient processing and low production cost.
