Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belongs to the scope of the utility model protection.
Referring to Fig. 1, the utility model provides a kind of technical scheme：Brake type front-wheel wheel shaft in a kind of bicycle, including
Stator 1, right shell body 7, spring 15 and pushing block 16, the right side of stator 1 are connected with left crotch 2, and stator 1 is detachable apparatus,
And stator 1 is provided with two, it is separately mounted to that rotary shaft is installed in the left left side of crotch 2 and the right side of right crotch 8, left crotch 2
3 are held, the right side of swivel bearing 3 is provided with left flower-drum 4, the left right side of flower-drum 4 is fixed with rotary shaft 5, and the right side of rotary shaft 5 is connected with
Ball bearing 6, the right side of right shell body 7, which is provided with right crotch 8, right crotch 8, is provided with movable block 10, and the lower section of movable block 10 is provided with
Fix bar 9, the right side of fix bar 9, which is provided with connecting rod 12, connecting rod 12, is fixed with push rod 13, and the end of connecting rod 12, which is connected with, stops
