Specific embodiment
It should be noted that in the case where there is no conflict, the feature in embodiment and embodiment in the present invention can phase
Mutually combination.
In order to achieve the above objectives, the technical proposal of the invention is realized in this way：
The bicycle loss prevention front fork, as shown in the figure, including connecting tube 1, link 2 and fork leg, 1 lower end of connecting tube and company
It connects 2 middle-end of frame to be fixedly connected, connecting tube 1 and link 2 are perpendicular, and 2 both ends of link, which are fixedly connected with, is parallel to connecting tube 1
Fork leg, fork leg and connecting tube 1 be located at the both sides of link 2 respectively, and the fork leg includes piston rod 3 and fork cylinder 4, piston rod 3
