Technical Field
[0001] This utility model relates to the field of bicycle stem technology, and in particular to a bicycle stem that is easy to adjust. Background Technology
[0002] The bicycle stem, commonly known as the handlebars, is the core component of a bicycle that connects the frame and the fork to control direction. Its length and angle together affect the overall top tube length, which needs to be determined through actual measurement to meet the rider's extension needs and avoid interference while riding. Increasing the stem length can improve power efficiency but reduce handling flexibility, while shortening it improves handling and visibility. Among them, a bicycle stem that is easy to adjust the handlebars can be adjusted conveniently, improving the ease of use. For example, a Chinese patent discloses a bicycle stem that is easy to adjust the handlebars (authorization announcement number CN223253188U). This patent technology sets one end of the stem as a fixed part that is connected to a locking part. The separate locking part can be easily disassembled and replaced with different styles of handlebars. The observation hole on the locking part matches the angle scale on the handlebar, improving the convenience of handlebar adjustment. However, existing publicly available bicycle handlebar stems that facilitate handlebar adjustment still have some shortcomings in practical applications and need improvement, such as: Once the bicycle stem is fixed to the bicycle fork, the angle is fixed and cannot be adjusted again. This is not conducive to the accuracy of the handlebar installation, or it may require complete removal for adjustment, which is not conducive to the convenience of the handlebar installation and has low installation efficiency. The positioning components are a split structure, which has low support firmness and is not conducive to the stability of the bicycle stem installation. The handlebars are adjusted by rotating within a fixed structure. Adjustment requires disassembling and reassembling the screws in this fixed structure, which is difficult. Frequent adjustments lead to handlebar wear, affecting the handlebars' appearance and compromising their stability after each disassembly and reassembly, posing a safety hazard. Therefore, those skilled in the art have provided a bicycle stem design that facilitates handlebar adjustment, addressing the problems mentioned in the background section. Utility Model Content
