Problems solved by technology

[0002] Bicycle is one of the means of transportation commonly used by people. The front fork of an ordinary bicycle plays the role of fixing the front axle and controlling the steering. In order to save space and be easy to carry, people have developed a folding bicycle on the basis of ordinary bicycles. For the combination of bicycle faucet and brake, bicycle front bracket and front fork, realizing folding sequentially is a relatively difficult technical problem to be solved. The applicant of the present invention has studied this technical problem before, and on this basis Applied for the patents of "Bicycle Rotating Brake Handle Device" and "Bicycle Folding Faucet"; a kind of folding bicycle is currently on th

Description

technical field [0001] The invention relates to the field of bicycle parts. In particular, it relates to a structure of a bicycle front bracket part. Background technique [0002] Bicycle is one of the means of transportation commonly used by people. The front fork of an ordinary bicycle plays the role of fixing the front axle and controlling the steering. In order to save space and be easy to carry, people have developed a folding bicycle on the basis of ordinary bicycles. For the combination of bicycle faucet and brake, bicycle front bracket and front fork, realizing folding sequentially is a relatively difficult technical problem to be solved. The applicant of the present invention has studied this technical problem before, and on this basis Applied for the patents of "Bicycle Rotating Brake Handle Device" and "Bicycle Folding Faucet"; a kind of folding bicycle is currently on the market, which divides the front bracket part of the bicycle into two, or one into three, an...
