Fig. 6 is a schematic diagram 2 of the adjustment action of the angle direction of the driving handle of the present invention.

Referring to Figure 1, a quick release device includes a combination of a shaft 10 and a drive handle 20. The driving handle 20 is configured to be disposed at one end of the rod body 10, and the driving handle 20 can drive the rod body 10 to rotate, whereby the quick release device can provide a rotary pressing function.

Referring to Figure 2, the shaft 10 has an axial direction 12. One end of the axial direction 12 is a first end 14 and the other end of the axial direction 12 is a second end 16. In particular, the first end 14 has a first receiving aperture 18. The first receiving hole 18 is a polygonal hole such as a quadrangular shape, a hexagonal shape, an octagonal shape or the like. Further, the outer surface of the second end 16 of the shaft 10 has a threaded portion 17.

Referring to FIG. 3, the drive handle 20 includes a head 22 coupled to a handle 24. The head 22 has an end face 26, and a drive head 28 is convexly disposed on the end face 26. In particular, the drive head 28 has a second receiving hole 30 in the axial direction. The drive head 28 is a polygonal cylinder such as a quadrilateral, hexagonal, octagonal or other similarly shaped cylinder.

Referring to FIG. 2 again, a first attachment member 32 is mounted in the first receiving hole 18 of the rod 10. Referring to FIG. 3 again, a second attachment member 34 is mounted in the second receiving hole 30 of the driving handle 20. At least one of the first attachment element 32 and the second attachment element 34 described above is a magnetic element, such as a magnet, and the other attachment element is a magnetic metal.

Referring to FIG. 4, the shape of the driving head 28 conforms to the shape of the first receiving hole 18. The drive head 28 of the drive handle 20 can be used to fit within the first receiving aperture 18 of the shaft 10, and the first attachment element 32 engages the second attachment element 34. The first attachment member 32 and the second attachment member 34 of the embodiment are both magnets, whereby the first attachment member 32 can be improved. The second attachment elements 34 have an absorbing force between each other.

The quick release device structure disclosed in this embodiment can be mounted on a bicycle (not shown). More specifically, the combination of the shaft 10 and the drive handle 20 can utilize the second end 16 of the shaft 10 through the front fork tube assembly or the rear fork tube assembly of the bicycle and through the front wheel hub Or rear wheel hub. Subsequently, the threaded portion 17 of the outer surface of the second end 16 engages a suitable nut (not shown). Rotating the driving handle 20, the combination of the rod body 10 and the nut can promote the front fork pipe set or the rear fork pipe assembly, the quick release device and the front wheel hub or the rear wheel hub, and the three forms are stable Tightly combined state.

Generally, after the quick release device is installed, the driving handle 20 has a suitable direction or angle upward or backward. If the driving handle 20 faces the front of the bicycle, the bicycle is likely to cause foreign matter to be caught on the driving handle 20 when the bicycle moves. The situation.

For the structural form of the embodiment, referring to FIG. 5, the user can apply force to disengage the first attachment member 32 and the second attachment member 34, whereby the drive handle 20 can be separated from the rod body 10. . Referring to FIG. 6 , the driving head 28 of the driving handle 20 is placed into the first receiving hole 18 at an appropriate angle and direction to make the first attachment component 32 and the second attachment component 34 . Magnetically combined. Thus, the driving handle 20 can be positioned at a suitable direction and angle, and the bicycle traveling process can reduce the probability of foreign matter being caught in the quick release device, and the driving handle 20 does not easily fall off.

According to the description of the above embodiments, the positioning structure disclosed in the present invention has a simplified and simplified structure, and the operation mode can achieve a simple and quick effect.

The above is a preferred embodiment and a design of the present invention.
