The conical pressure guide seat 4 is pre-installed in the middle of the grip handle 2 through the connecting bolt 3. Then, keeping the limiting protrusion 6 facing upward, the grip handle 2 is aligned and installed on the upper part of the mounting end tube of the handlebar bracket 1. During installation, the installation position of the grip handle 2 is adjusted by axial pulling and moving according to the user's riding preferences and body characteristics, so that the limiting protrusion on the upper part of the internal socket 5 is adjusted. The positioning protrusion 6 is engaged and locked with the corresponding limiting hole 7 on the side of the mounting end tube. Then, the connecting bolt 3 is tightened by screwing with a hex wrench. During the process, the connecting bolt 3 is used to tighten and pull the conical pressure guide seat 4, so that the conical pressure guide seat 4 and the inner surface of the conical guide groove 9 slide and push to support. Through the inner pushing support, the limiting protrusion 6 can be tightly engaged and supported with the limiting hole 7 on the upper part of the mounting end tube, so as to achieve a stable locking and limiting of the grip handle 2 after installation. After installation, the sealing end gasket 12 is installed on the rear opening side of the bolt mounting hole 8 to complete the connection and installation of the grip handle 2.

[0033] In summary, this bicycle handlebar is made of carbon fiber and adopts a split, detachable mounting structure. The grip handle 2 is installed as an independent component on the mounting end tube side of the handlebar bracket 1. The grip handle 2 is installed by aligning and inserting with the mounting end tube of the handlebar bracket 1 through the internal socket 5, and adopts an internal expansion snap-fit ​​limiting structure. The conical pressure guide seat 4 is fastened and pulled by the connecting bolt 3 and fitted into the conical guide groove 9 in the middle of the internal socket 5. The inner guide push support allows the limiting protrusion 6 to snap into the limiting hole 7 on the upper part of the mounting end tube for support and installation. This design enables stable locking of the handle 2 after installation. Its simple structure and easy assembly / disassembly enhance the convenience and stability of the handle 2. The design employs a snap-hole limiting installation structure, with the limiting snap holes 7 evenly spaced on the upper part of the mounting tube. During installation, the support length of the handle 2 can be adjusted by changing the engagement position of the limiting protrusion 6 and the limiting snap holes 7. This adjustment is convenient and quick, allowing for flexible adjustment of the handle 2's installation position according to the user's body type and riding preferences, thus improving the handle's operational flexibility.
