[0020] The present invention will be further described in detail below with reference to the accompanying drawings.

[0021] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law. Example 1:

[0022] A pole fixing device, as shown in the figure Figures 1 to 4 The structure includes a support pole 1 and a fixing mechanism. In this embodiment, the support pole 1 is provided with multiple locking holes 11 arranged at intervals along the length direction. The fixing mechanism adjusts its height position on the support pole 1 through the locking holes 11. Specifically, in this embodiment, the fixing mechanism includes a sliding sleeve 2, a support part 3, and a fixing seat 4. The sliding sleeve 2 is sleeved on the support pole 1 and can slide relative to the support pole 1. One end of the support part 3 is connected to the sliding sleeve 2, and the other end is connected to the fixing seat 4. The fixing seat 4 is provided with a strap 41, which cooperates with the fixing seat 4 to fix the vehicle body. In other optional embodiments, the strap 41 can also be replaced with other structures that can fix the vehicle body, and there is no limitation here.

[0023] Reference Figures 1 to 4 Preferably, the sliding sleeve 2 is provided with a bushing 21 that contacts the upright 1; the bushing 21 can prevent friction between the sliding sleeve 2 and the upright 1, and can also prevent squeezing or collision between the sliding sleeve 2 and the upright 1, playing a protective and noise reduction role, thereby extending the service life and optimizing the user experience; preferably, in this embodiment, two bushings 21 are provided in the sliding sleeve 2, which facilitates assembly and replacement and can reduce costs.

[0024] Reference Figures 1 to 4 In this embodiment, the support part 3 is provided with a receiving cavity with a top opening. The locking component and the unlocking component are installed into the receiving cavity through the top opening. The support part 3 is provided with a protective cover 5 that covers the receiving cavity. The protective cover 5 protects the locking component and the unlocking component, preventing debris or rainwater from entering the receiving cavity and extending its service life.

[0025] Reference Figures 1 to 4 In this embodiment, the locking assembly includes a locking pin 61 and a spring 62; a first through hole 31 for the locking pin 61 to pass through is provided on the inner wall of one end of the receiving cavity, and a positioning post 32 embedded in the spring 62 is provided on the inner wall of the other end; the spring 62 is sleeved on the locking pin 61, and a limiting protrusion 611 that contacts the spring 62 is provided on the locking pin 61; that is, one end of the spring 62 contacts the limiting protrusion 611, and the other end contacts the inner wall of the receiving cavity; the fact that one end of the spring 62 is sleeved on the locking pin 61 and the other end is sleeved on the positioning post 32 can improve the stability of the spring 62; Reference Figures 1 to 4 The sliding sleeve 2 has a second through hole opposite to the first through hole 31, and the bushing 21 has a third through hole opposite to the second through hole; that is, after the locking pin 61 passes through the first through hole 31, the second through hole and the third through hole in sequence, it is embedded in the locking hole 11 on the upright 1, thereby achieving locking; wherein, the elastic force of the spring 62 makes the locking pin 61 have a tendency to move into the locking hole 11, thereby maintaining the locked state.

[0026] Reference Figures 1 to 4 The unlocking component includes an unlocking button 71 and a driving block 72. The unlocking button 71 extends from the bottom wall of the receiving cavity for easy pressing. The driving block 72 is sleeved on the locking pin 61, and the driving block 72 and the spring 62 are located on both sides of the limiting protrusion 611. A driving ramp 73 is provided between the unlocking button 71 and the driving block 72 to change the direction of the driving force, thereby facilitating operation. Of course, in other optional embodiments, the moving direction of the unlocking button can also be parallel to the moving direction of the locking pin, which is not limited here.

[0027] Reference Figures 1 to 4 One end of the drive block 72 contacts the unlock button 71, and the other end contacts the limiting protrusion 611. Pressing the unlock button 71 causes it to move upward. The driving force of the unlock button 71 is transmitted to the locking pin 61 through the drive inclined surface 73, the drive block 72, and the limiting protrusion 611, causing the locking pin 61 to move until it disengages from the locking hole 11, thus unlocking the device. This allows control of the movement of the sliding sleeve 2 and adjustment of its height. The first through hole 31 restricts the locking pin 61 to move only axially, while the unlock button 71 has a movable hole 711 that mates with the locking pin 61. That is, the movable hole 711 provides the unlock button 71 with a travel distance to avoid interference.

[0028] Reference Figures 1 to 4After the unlock button 71 is released, the locking pin 61 moves back to its original position under the elastic force of the spring 62 and is inserted into the locking hole 11, thus re-locking. If the locking pin 61 contacts the outer wall of the upright 1, the sliding sleeve 2 moves up and down, and the locking pin 61 automatically inserts into the locking hole 11 after being aligned with it, thereby achieving locking.

[0029] Reference Figures 1 to 4 The drive ramp 73 makes the movement direction of the unlock button 71 perpendicular to the movement direction of the locking pin 61, which not only saves installation space but also makes operation convenient. The spring 62 not only keeps the locking pin 61 and the locking hole 11 in the locked state, but also enables automatic locking, which is convenient to operate and optimizes the user experience.

[0030] Reference Figures 1 to 4 In this embodiment, the drive block 72 is sleeved on the locking pin 61, which facilitates processing and assembly. Of course, in other optional embodiments, the drive block 72 can also be fixedly connected to the locking pin 61 or integrally formed, which is not limited here. In this case, the drive block can also play a limiting role, so the limiting protrusion can be eliminated. Example 2:

[0031] A bicycle bracket, as shown Figures 1 to 5 It includes a base frame 8, on which the pole fixing device of Embodiment 1 is provided; specifically, the pole 1 is provided on the base frame 8.
