[0032] Among them, the locking member can be components such as bolts and buckles. Other detachable fixing structures that can be realized are acceptable. The installed detachable locking member enables the top cover 401 and the ring 403 to be quickly disassembled and assembled.
[0033] As Figure 2 、 4 shown, the front fork locking device 5 includes a locking tube 501. On one side of the lower end of the locking tube 501, four groups of mounting holes 6 are fixedly connected. The mounting holes 6 are pairwise corresponding, and two groups of mounting holes 6 are fixedly connected by mounting bolts 7. The mounting holes 6 are in rolling connection with the mounting bolts 7. On both sides of the upper end of the locking tube 501, limit blocks 502 are respectively fixedly connected. The upper end of the locking tube 501 is in sliding connection with the beam tube 3.
[0034] In the above manner, when assembling the bicycle, the front fork is placed into the groove opened at the lower end of the locking tube 501 in the front fork locking device 5, the mounting bolt 7 is placed in the mounting hole 6, and it is tightened and fixed.
[0035] As Figure 2 、 3 、4 shown, an annular groove is opened on the outer side of the upper end of the beam tube 3. The circular ring 403 is arranged in the annular groove opened on the beam tube 3, and the circular ring is in rotational connection with the beam tube 3. A through hole is opened at the upper middle of the beam tube 3. The threaded rod 402 is arranged in the through hole opened on the beam tube 3, and the threaded rod 402 is in rotational connection with the through hole opened on the beam tube 3. A groove is opened at the lower end of the beam tube 3. Grooves are respectively opened on both sides of the groove opened at the lower end of the beam tube 3. The locking tube 501 is arranged in the groove opened at the lower end of the beam tube 3, and the locking tube 501 is in sliding connection with the groove opened at the lower end. The limit blocks 502 are arranged in the grooves opened on both sides of the groove opened at the lower end of the beam tube 3, and the limit blocks 502 are in sliding connection with it.
[0036] In the above manner, the annular groove opened on the outer side of the upper end of the beam tube 3 is for enabling the threaded rod 402 in the rotating device 4 to drive the beam tube 3 to move upward together when moving upward, so as to realize the adjustment of the height of the handlebar tube; the groove opened at the lower end of the beam tube 3 is for enabling the beam tube 3 to slide better with the locking tube 501 during the upward movement of the beam tube 3; the grooves are opened on both sides of the groove opened at the lower end of the beam tube 3 and the limit blocks 502 are arranged therein, which is for enabling the rotating device 4 to limit the beam tube 3 during rotation to prevent the beam tube 3 from rotating, and opening the grooves on both sides of the groove opened at the lower end of the beam tube 3 can enable the handlebar tube to have a controllable range during the up and down adjustment to prevent the occurrence of the falling-off phenomenon.

[0040] In the above method, when adjusting the height of the handlebar stem, by rotating the ring 403 at the upper end of the cable housing 3, the top cover 401 rotates with the rotation of the ring 403. Due to the rotation of the top cover 401, the threaded rod 402 rotates together. Due to the rotation of the threaded rod 402, the threaded rod 402 in the threaded groove opened at the upper end of the locking tube 501 rotates upward, driving the handlebar locking device 2, the cross tube 1, the rotating device 4, and the cable housing 3 to move upward.
[0041] The working principle of this utility model is as follows: When preparing to adjust the height of the handlebar stem, first assemble the bicycle. Place the handlebar between the first pressing block 201 and the second pressing block 202 in the handlebar locking device 2, place the mounting bolt 7 in the mounting hole 6 and tighten it for fixation. At the same time, place the front fork into the groove opened at the lower end of the locking tube 501 in the front fork locking device 5, place the mounting bolt 7 in the mounting hole 6 and tighten it for fixation. At this time, start to adjust the height of the handlebar stem. By rotating the ring 403 at the upper end of the cable housing 3, the top cover 401 rotates with the rotation of the ring 403. Due to the rotation of the top cover 401, the threaded rod 402 rotates together. Due to the rotation of the threaded rod 402, the threaded rod 402 in the threaded groove opened at the upper end of the locking tube 501 rotates upward, driving the handlebar locking device 2, the cross tube 1, the rotating device 4, and the cable housing 3 to move upward, thus completing this series of operations.
[0042] The above is only the preferred embodiment of the present utility model.
