Description

Technical Field

[0001] The utility model relates to a bicycle, in particular to a segmented handlebar riser mechanism. Background Art

[0002] The handlebar and stem of a traditional bicycle are both separate accessories. The handlebar is inserted into the round hole of the stem extension tube and then fixed by screws. When adjusting the handlebar angle, the screw group on the stem extension tube needs to be loosened. After adjusting the handlebar angle, the handlebar angle can be adjusted according to the angle of the rider's operation. Because the stem extension tube is of a fixed length, the length of the stem cannot be adjusted, and the angle of the handlebar posture cannot be adjusted. Specifically, the existing bicycle handlebar is installed on the stem of the bicycle head in a tubular shape. The handlebar passes through the front extension lock hole of the stem. The front extension tube has a semicircular structure. After the handlebar is inserted into the semicircular structure, it is locked with another semicircular locking cover. The locking cover has a set of locking holes. The handlebar is locked in the inside of the stem extension tube round hole by tightening the screws. The handlebar grip can be locked by adjusting the handlebar grip. However, because the handlebar is an integrated structure, the handlebar grip cannot be freely adjusted according to personal needs, and the length of the stem extension part cannot be adjusted according to the rider's arm length. It does not meet the application needs of most people for flexible adjustment of the handlebar telescopic position. Utility Model Content
