[0026] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 5 Through the structural design of handlebar main body 1, positioning seat 2, knob 3, rotating stick 4, driving gear 5, chain 6, two-way threaded rod 7, transmission gear 8 and extension arm 9, and the mutual cooperation between structures, the function that the handlebar width is flexibly adjusted is realized, so that the handlebar can be adjusted according to the use demand of different users, thereby the comfort degree when riding is improved, and the controllability of the bicycle is enhanced, and the discomfort and fatigue caused by the traditional fixed size handlebar to the user are avoided.
[0027] The distal end of extension arm 9 is fixedly installed with assembly rod 10, and the distal end of assembly rod 10 is fixedly installed with handle 11.
[0028] Refer to Figure 1 and Figure 4The extension arm 9 and the handle 11 are connected through the assembling rod 10, and the handle 11 is convenient for the rider to hold and control the bicycle.
[0029] The other side of the positioning seat 2 is fixedly provided with a pin hole 12, the inside of the pin hole 12 is provided with a positioning pin 13, and the side of the driving gear 5 is provided with a plurality of positioning holes 14.
[0030] With reference to Figure 1 and Figure 3 , the cooperation of the pin hole 12, the positioning pin 13 and the positioning hole 14 realizes the fixing function, thereby the driving gear 5 is constrained, so as to ensure the stability of the driving gear 5 after adjustment, and further ensure the safety of the whole handlebar during use.
[0031] The both sides of the middle part of the inner cavity of the handlebar body 1 are fixedly provided with bearings 15, and the bearings 15 are sleeved to the surface of the bidirectional threaded rod 7.
[0032] With reference to Figure 3 and Figure 5 , the bearings 15 are convenient for limiting the bidirectional threaded rod 7, and can also reduce the friction force when the bidirectional threaded rod 7 rotates, so as to ensure the smoothness and stability of the rotation.
[0033] The middle part of the side close to the bidirectional threaded rod 7 of the extension arm 9 is provided with a threaded hole 16, the internal thread of the threaded hole 16 is matched with the surface thread of the bidirectional threaded rod 7, and the threaded hole 16 is in threaded engagement with the bidirectional threaded rod 7.
[0034] With reference to Figure 2 , Figure 3 , Figure 4 , Figure 5 , the threaded hole 16 is convenient for matching the thread on the surface of the bidirectional threaded rod 7 to realize the synchronous movement of the two extension arms 9, thereby the adjustment steps of the handlebar can be simplified.

[0039] Working principle: When using this device, rotating the knob 3 causes the rotating roller 4 to rotate, and the drive gear 5 on the rotating roller 4 rotates accordingly. The drive gear 5 transmits power to the transmission gear 8 through the chain 6, causing the transmission gear 8 to drive the bidirectional threaded rod 7 to rotate under the support of the bearing 15. Since the threads on both sides of the bidirectional threaded rod 7 are opposite, the extension arm 9, which meshes with the threads of the bidirectional threaded rod 7, will make relative or opposite linear movements when the bidirectional threaded rod 7 rotates. During this period, the stability of the extension arm 9 during movement is ensured by the slot 17 and the locking strip 18. The movement of the extension arm 9 drives the handlebar 11 to move through the mounting rod 10, thereby realizing the adjustment of the handlebar width. When the handlebar is adjusted to the appropriate width, the positioning pin 13 is inserted through the pin hole 12 and then inserted into the corresponding positioning hole 14 on the drive gear 5 to lock the width of the handlebar.
