DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementation methods of the utility model, and does not strictly limit the scope of protection of the specific request of the utility model.

[0023] The rotating device 4 includes a first positioning piece 401 and a threaded rod 402 , and the first positioning piece 401 is used to drive the threaded rod 402 to rotate.
[0024] In this implementation case, the bicycle is assembled first, the handlebar is placed between the upper cover plate 601 and the lower cover plate 602 in the handlebar locking device 6, the mounting bolt 8 is placed in the middle of the mounting hole 7, and it is tightened to fix the handlebar. At the same time, the front fork is placed in the front fork locking tube 2, the mounting bolt 8 is placed in the middle of the mounting hole 7, and it is tightened to fix the front fork. If you want to fold the stem, use a hexagonal tool that matches the outer side of the first positioning piece 401 and turn it to loosen it. Since the first positioning piece 40 1 is rotated, so that the threaded rod 402 rotates together. At this time, the second positioning piece 403 is controlled not to rotate, so that the threaded rod 402 rotates in the threaded hole opened by the second positioning piece 403, so that a gap is generated between the cross tube 3 and the fixing blocks 5 on both sides. At this time, the fixing blocks 5 are rotated, so that the handlebar locking device 6 rotates, so that the handlebar locking device 6 rotates to the other side of the front fork locking tube 2. At this time, the front fork locking tube 2 is located between the two groups of fixing blocks 5, and the rotating device 4 is tightened to fix the position after rotation, thereby completing a series of work.
[0025] like Figure 2 As shown, the handlebar locking device 6 includes an upper cover plate 601 and a lower cover plate 602, and the four corners of the upper cover plate 601 and the lower cover plate 602 are respectively fixedly connected with mounting holes 7, and the four corner mounting holes 7 of the upper cover plate 601 and the lower cover plate 602 correspond to each other one by one, and the four corner mounting holes 7 are fixedly connected by mounting bolts 8, and one side of the lower cover plate 602 is fixedly connected to the fixing block 5.
[0026] In the above method, the bicycle is assembled first, the handlebar is placed between the upper cover plate 601 and the lower cover plate 602 in the handlebar locking device 6, the mounting bolt 8 is placed in the middle position of the mounting hole 7, and is tightened to fix the handlebar.
[0027] like Figure 2 As shown, one side of the front fork locking tube 2 is fixedly connected to the straight tube 1, and a through hole is opened on the other side of the front fork locking tube 2. Both sides of the through hole opened on the front fork locking tube 2 are fixedly connected to four groups of mounting holes 7 respectively. The four groups of mounting holes 7 correspond to each other, and two groups of mounting holes 7 are fixedly connected by mounting bolts 8.
[0028] In the above method, the bicycle is first assembled, the front fork is placed in the front fork locking tube 2, the mounting bolt 8 is placed in the middle position of the mounting hole 7, and is tightened to fix the front fork.
[0029] like Figure 2 and Figure 3 As shown, the first positioning piece 401 is arranged on one side of the transverse tube 3 , the first positioning piece 401 is fixedly connected to the threaded rod 402 , and the other end of the threaded rod 402 is threadedly connected to the second positioning piece 403 .
[0030] In the above method, if you want to fold the stem, use a hexagonal tool that matches the outer side of the first positioning piece 401, and rotate it to loosen it. As the first positioning piece 401 rotates, the threaded rod 402 rotates along with it. At this time, the second positioning piece 403 is controlled not to rotate, so that the threaded rod 402 rotates in the threaded hole opened by the second positioning piece 403, so that a gap is generated between the cross tube 3 and the fixing blocks 5 on both sides. At this time, the fixing blocks 5 are rotated, so that the handlebar locking device 6 rotates, and the handlebar locking device 6 rotates to the other side of the front fork locking tube 2. At this time, the front fork locking tube 2 is located between the two sets of fixing blocks 5, and the rotating device 4 is tightened to fix the position after rotation.
[0031] like Figure 3 As shown, two groups of fixing blocks 5 have through holes at one end away from the handlebar locking device 6, and a through hole is opened in the middle of the cross tube 3, and the through holes opened in the fixing blocks 5 correspond to the through holes opened in the cross tube 3. The two groups of fixing blocks 5 are respectively arranged on both sides of the cross tube 3, and the threaded rod 402 is arranged in the through holes opened in the fixing blocks 5 and the cross tube 3. The fixing blocks 5 are hinged to the cross tube 3 through the threaded rod 402, and the distance between the two groups of fixing blocks 5 is greater than the width of the front fork locking tube 2.
[0032] In the above method, when the stem is folded, a hexagonal tool matching the outer side of the first positioning piece 401 is used to rotate and loosen it. As the first positioning piece 401 rotates, the threaded rod 402 rotates along with it. At this time, the second positioning piece 403 is controlled not to rotate, so that the threaded rod 402 rotates in the threaded hole opened by the second positioning piece 403, so that a gap is generated between the cross tube 3 and the fixing blocks 5 on both sides. At this time, the fixing blocks 5 are rotated, so that the handlebar locking device 6 rotates, and the handlebar locking device 6 rotates to the other side of the front fork locking tube 2. At this time, the front fork locking tube 2 is located between the two sets of fixing blocks 5, and the rotating device 4 is tightened to fix the position after rotation.
[0033] like Figures 1 to 3 As shown, a hexagonal groove is formed at one end of the first positioning piece 401, and a threaded through hole is formed at the second positioning piece 403. The threaded through hole formed in the second positioning piece 403 matches the threaded rod 402, and the first positioning piece 401 and the second positioning piece 403 are respectively arranged on the outside of the two groups of fixing blocks 5.
[0034] In the above manner, a hexagonal groove is formed at one end of the first positioning piece 401, so that the handlebar can be folded more quickly without complicated operation procedures. By rotating the first positioning piece 401, the threaded rod 402 is rotated, so that a gap is generated between the rotating device 4 and the cross tube 3 and the fixed block 5, so that the fixed block 5 will not be restricted when rotating, so that it can be rotated quickly and the handlebar can be folded.
[0035] The working principle of the utility model is as follows: firstly, assemble the bicycle, put the handlebar into the middle of the upper cover plate 601 and the lower cover plate 602 in the handlebar locking device 6, put the mounting bolt 8 into the middle position of the mounting hole 7, and tighten it to fix it; at the same time, put the front fork into the front fork locking tube 2, put the mounting bolt 8 into the middle position of the mounting hole 7, and tighten it to fix it; if you want to fold the stem, use a hexagonal tool that matches the outer side of the first positioning piece 401, and rotate it to loosen it; as the first positioning piece 401 rotates, the bolt 8 is tightened. The threaded rod 402 rotates together. At this time, the second positioning piece 403 is controlled not to rotate, so that the threaded rod 402 rotates in the threaded hole opened by the second positioning piece 403, so that a gap is generated between the cross tube 3 and the fixing blocks 5 on both sides. At this time, the fixing blocks 5 are rotated, so that the handlebar locking device 6 rotates, and the handlebar locking device 6 rotates to the other side of the front fork locking tube 2. At this time, the front fork locking tube 2 is located between the two sets of fixing blocks 5, and the rotating device 4 is tightened to fix the position after rotation, thereby completing a series of tasks.
