[0002] A bicycle, also known as a bike or a bicycle, is usually a small two-wheeled land vehicle. When a person rides on the bicycle, they use pedals as power, and it is a green and environmentally friendly means of transportation.

[0003] The Chinese patent with the announcement number CN206938978U discloses an integrated handlebar and front fork connection structure, which includes a handlebar and a front fork tube, a fixing seat, a vertical tube and a tungsten wire are arranged between the handlebar and the front fork tube; the lower end of the vertical rod is inserted into the front fork tube and fixed by a wrist assembly, the tungsten wire is placed in the front fork tube and is located below the vertical tube, and the tungsten wire and the lower end surface of the vertical tube are matched by an inclined surface; a ceiling screw is provided, which passes through the fixing seat and the vertical tube in sequence and is locked on the inclined surface of the tungsten wire; a groove is provided on the outer surface of the vertical tube, and a protrusion is provided on the inner side of the front fork tube, and the protrusion is clamped in the groove to stop the front fork tube and the vertical tube from rotating in the circumferential direction. The vertical tube and the front fork tube of the integrated handlebar and front fork connection structure are matched by the tungsten wire inclined surface, which can reduce the vertical tube radius and drive the tungsten wire to lift by the ceiling screw to improve the tight fit between the two, thereby fixing the two, and a foolproof structure is provided on the front fork tube and the vertical tube to prevent the handlebar from rotating during use or when the ceiling screw is not firmly locked, thereby improving the convenience of use.

[0004] With respect to the above-mentioned related technologies, in the prior art, the staff uses bolts to connect the fixing seat and the vertical pipe. However, during the connection process, it is necessary to align the hole of the fixing seat and the hole of the vertical pipe by observation in advance, so that the fixing seat and the vertical pipe can be smoothly connected by bolts using tools to locate the installation direction of the handlebar. The process is relatively cumbersome, which prolongs the installation time of the handlebar and reduces the installation efficiency of the handlebar. Utility Model Content

When installing the handlebar, the staff puts the handlebar sleeve on the front fork tube, makes the positioning flange slide and fit in the positioning notch, and finally uses the locking assembly to lock the handlebar to achieve the installation of the handlebar. The staff uses the cooperation of the positioning flange and the positioning notch to locate the installation direction of the handlebar on the front fork tube. Compared with the existing technology, the installation steps are fewer and the installation is faster, which shortens the installation time of the handlebar and improves the installation efficiency of the handlebar;

[0025] 2. When locking the handlebar, the staff installs the ratchet into the front fork tube, then sets the handlebar sleeve on the front fork tube, and finally passes the top bolt through the handlebar and matches it with the tie rod bolt thread until the top bolt is pressed against the handlebar. During this process, the top bolt rotates, driving the tie rod bolt to rotate, thereby shortening the distance between the upper block and the lower block, causing several ratchets to expand and press against the inner wall of the front fork tube, thus achieving the effect of locking the handlebar;

[0026] 3. When locking the handlebar, the staff puts the handlebar sleeve on the front fork tube, then moves the locking ring to drive all the hooks to rotate, so that the hooks enter the grooves, and then rotates the locking ring to move the locking ring and resist the locking ring, thereby achieving the effect of locking the handlebar;

[0027] 4. When the pawl is installed into the front fork tube, it is necessary to restrict the pawl, otherwise the pawl will easily fall into the deep of the front fork tube. When positioning the pawl, the staff will install the mounting bolt into one of the pawls, and then press the pawl into the front fork tube. During this process, the piston rod enters the moving hole, and the ejector spring deforms until the piston rod is aligned with the positioning hole. The piston rod moves under the force of the ejector spring and is inserted into the positioning hole of the front fork tube. Then, the handlebar sleeve is set in the front fork tube, and the piston rod is pressed to align the positioning hole of the handlebar with the positioning hole of the front fork tube.
