Technical Field

[0001] This utility model relates to the technical field of yarn bonding and pressing devices, specifically a yarn bonding and pressing device with a replaceable structure for bicycle handlebar processing. Background Technology

[0002] With the trend towards lightweight and high-performance bicycles, carbon fiber composite materials, due to their high strength, low density, and high designability, have become the mainstream manufacturing material for high-end bicycle handlebars (such as road bike, mountain bike, and time trial handlebars). Among them, the handlebar stem, as a key component connecting the frame and the fork, directly affects riding safety and handling experience due to its mechanical properties and molding precision.

[0003] However, most yarn-attaching pressing devices use fixed molds when processing bicycle handlebars, which can only process specific handlebar models and are inconvenient for processing different sizes of handlebars. This results in the need to disassemble the entire pressing mold system when changing molds, which is time-consuming and affects production efficiency. Therefore, we need to propose a yarn-attaching pressing device with a replaceable structure for bicycle handlebar processing. Utility Model Content
