DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(8) Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.

(9) Referring to FIGS. 4 to 7, a quick-release structure capable of storing a rotating handle, comprising a shaft 20 and a driving assembly 30. The outer circumferential surface of one end of the shaft 20 has a first threaded section 21. The other end of the shaft 20 has a round shaft head 22. The outer end of the first threaded section 21 is formed with a receiving hole 23 that is recessed inwardly along the axial direction of the shaft 20. The outer end of the round shaft head 22 is formed with a connecting hole 24 having a predetermined shape. The connecting hole 24 is recessed inwardly along the axial direction of the shaft 20. The shaft 20 has an inner hole 25 extending from the connecting hole 24.

(10) The driving assembly 30 includes a rotating handle 31 and a connecting rod 32. The rotating handle 31 is pivotally connected to the connecting rod 32. The rotating handle 31 is in the form of a rod. The outer circumferential surface of one end of the rotating handle 31 has a second threaded section 33. The other end of the rotating handle 31 has a connecting end 34. The outer circumferential surface of the rotating handle 31 is formed with a first annular groove 35 adjacent to the second threaded section 33. An end cap 36 is screwed to the second threaded section 33. A first O-ring 37 is sleeved on the first annular ring groove 35. The connecting rod 32 is in the form of a rod. The connecting rod 32 includes a pivoting end 38, a driving section 39, and a tool head 40 that are arranged in sequence along the axial direction of the connecting rod 32 from one end thereof. A second annular groove 41 is formed between the pivoting end 38 and the driving section 39. A second O-ring 42 is sleeved on the second annular groove 41. The connecting end 34 of the rotating handle 31 is pivotally connected to the pivoting end 38 of the connecting rod 32, so that the rotating handle 31 can pivot at least 90 degrees relative to one side of the connecting rod 32. The outer diameter of the driving section 39 is less than the outer diameter of the pivoting end 38, so that one end of the pivoting end 38 forms an annular stop edge 381 facing the driving section 39. The shape of the driving section 39 corresponds to the shape of the connecting hole 24 of the shaft 20, so that the tool head 40 and the driving section 39 of the connecting rod 32 can pass through the connecting hole 24 when in use. The outer diameter of the tool head 40 is less than the outer diameter of the driving section 39. When in use, the tool head 40 can easily pass through the connecting hole 24, the annular stop edge 381 is positioned against the outer end of the connecting hole 24 when in use, the tool head 40 is located in the inner hole 25, the driving section 39 is engaged in the connecting hole 24, and the rotating handle 31 can be turned to drive the shaft 20 to rotate. When not in use, the driving assembly 30 can be inserted into the receiving hole 23, the first O-ring 37 and the second O-ring 42 are against the inner circumferential surface of the receiving hole 23, and the end cap 36 leans against the outer end of the receiving hole 23 to be positioned, so that the rotating handle 31 is stored and positioned in the receiving hole 23. With the above structure, when not in use, the rotating handle can be stored and hidden in the quick-release structure, thereby preventing the situation that the user forgets the storage location of the rotating handle or losing the rotating handle accidentally.

(11) The assembly and function of the present invention are described in detail as follows. As shown in FIGS. 4 to 7, in the present invention, the rotating handle 31 can be hidden in the receiving hole 23 when not in use. As to the pivoting manner of the rotating handle 31 and the connecting rod 32, preferably, the connecting end 34 has a lateral through hole 341, and the pivoting end 38 has a pivoting slot 382 and a lateral perforation 383 communicating with the pivoting slot 382. One side of the pivoting slot 382 is provided with a stop wall 384. The connecting end 34 of the rotating handle 31 is assembled to the pivoting slot 382 of the connecting rod 32, and an axle 43 is inserted through the lateral through hole 341 and the lateral perforation 383 for connecting the rotating handle 31 and the connecting rod 32, but not limited thereto. As to the shape of the driving section 39 and the connecting hole 24, preferably, the driving section 39 is a polygonal rod, and the connecting hole 24 is a polygonal hole, but not limited thereto. When the rotating handle 31 is not used, the end having the tool head 40 of the driving assembly 30 is first inserted into the receiving hole 23, the end cap 36 for easy gripping is applied with a force, the first O-ring 37 and the second O-ring 42 are respectively compressed and elastically deformed into the receiving hole 23 to generate friction (as shown in FIG. 5), and finally the end cap 36 is pressed against the outer end of the receiving hole 23, such that the rotating handle 31 is stably stored in the receiving hole 23. When the rotating handle 31 needs to be used, the driving assembly 30 can be pulled out of the receiving hole 23 through the end cap 36. Then, the end having the tool head 40 of the driving assembly 30 is inserted through the connecting hole 24 into the inner hole 25. The annular stop edge 381 of the pivoting end 38 leans against the outer end of the connecting hole 24 to position the connecting rod 32 quickly. The driving section 39 of the connecting rod 32 is engaged in the connecting hole 24. The second O-ring 42 is compressed and forced into the connecting hole 24, so that the connecting rod 32 is positioned stably. Then, the rotating handle 31 is turned about the axle 43 in the pivoting slot 382 in a direction facing away from the stop wall 384 (as shown in FIG. 6). Preferably, the rotating handle 31 and the connecting rod 32 may be perpendicular to each other, that is, the rotating handle 31 can be turned to rotate the shaft 20, so that the threaded section 21 of the shaft 20 can be screwed to or unscrewed from a fork. Furthermore, the pivoting slot 382 has the stop wall 384 to increase the strength of endurance. In other words, the stop wall 384 is configured to strengthen the pivoting slot 382. It is worth mentioning that the connecting rod 32 is additionally provided with the tool head 40 that can be used for screwing other parts 44 (as shown in FIG. 7) to achieve an additional auxiliary tool.

(12) Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
