Finally, when the bicycle needs to be locked, the user can refer to Figures 2 and 3. The user only needs to pass the flexible member 2 around a bicycle (not shown), then insert the lock bolt 22 on the flexible member 2 into the lock bolt insertion hole 18, and lock the lock bolt 22 and the lock core 12 together through the control number swivel assembly 11, so that the bicycle can be locked simply and quickly. When unlocking, the control number rotating ring assembly 11 releases the locking state of the lock cylinder 12, and then the finger turns the turning member 14 to drive the lock cylinder 12 to move back relatively, so as to release the locking state between the lock cylinder 12 and the bolt 22. At this time, the bolt 22 is no longer locked by the lock cylinder 12 and can be directly pulled out of the bolt insertion hole 18, and then the flexible member 2 can unlock the locking state of the bicycle.

The bicycle handlebar built-in number lock provided by the present invention can be stored in the internal space 41 of the bicycle handlebar 4 together with the flexible member 2 when the lock is not needed, and the handlebar combination assembly 3 can provide an effective positioning function to ensure that it will not fall off the bicycle handlebar 4. In addition, the present invention can effectively solve the problem of conventional locks occupying space by storing the number lock in the bicycle handlebar 4, and can also avoid damaging the overall appearance of the bicycle, so that the bicycle handlebar built-in number lock of the present invention can save space and take into account the aesthetics at the same time, and is very practical.

As shown in FIG. 6, another embodiment of the bicycle handlebar built-in number lock provided by the present invention is different from the above-mentioned embodiment in that: the annular protrusion 34b of the bolt 31b is directly and integrally formed with a second threaded section 33b at one end facing the connecting section 17, and a pull ring 342b that can be pivoted relative to the annular protrusion 34b is pivoted on the annular protrusion 34b with a pivot 341b, so that the user can conveniently hold the bolt 31b with his fingers to rotate, so that the second threaded section 33b can drive the connecting section 17 that is mutually threaded with it to move, and further drive each clamping claw 362 to operate, and also has the function of simply and quickly completing its clamping and releasing state.

However, the disclosure of the above embodiments is only used to illustrate the present invention, not to limit the present invention. Any replacement of equivalent components should still fall within the scope of the present invention.

In summary, those familiar with the technology in this field can understand that the present invention can achieve the aforementioned purpose and has complied with the provisions of the Patent Law, and therefore the application is filed in accordance with the law.
