It is worth noting that the directional terms used in the following embodiments, such as up, down, left, right, front, or back, are only for reference to the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting the invention. Furthermore, in the following embodiments, the same or similar components will be referred to by the same or similar reference numerals.

[0053] Please see Figures 1 to 8As shown in the figure: The present invention provides a steering engagement structure 1, which includes a body 11, an operating part 12 and a fastening part 13.

[0054] The body 11 is provided on the object 10.

[0055] The operating part 12 is movablely combined with the body part 11.

[0056] The buckle 13 is movably disposed on the body 11 and combined with the operating part 12. The operating part 12 moves longitudinally and then rotates to drive the buckle 13 to fasten to another object 20 via the object 10 or to unfasten the buckle 13 on the other object 20.

[0057] When in use, the directional fastening structure 1 can be assembled onto the object 10 with the body 11. When using the directional fastening structure 1, pressure can be applied to the operating part 12 first to make the operating part 12 move downward longitudinally, and then a rotational force can be applied to make the operating part 12 rotate, so that the operating part 12 drives the fastening part 13 to move as well, and then the operating part 12 drives the fastening part 13 to fasten to the fastened part 201 of the other object 20 via the object 10.

[0058] Alternatively, a rotational force can be applied to the operating part 12 in the opposite direction, causing the operating part 12 to drive the buckle part 13 to rotate and move. Then, the operating part 12 can be lifted up, allowing the operating part 12 to drive the buckle part 13 away from the buckled part 201 of the other object 20 to unfasten it.

[0059] Based on the above description of the embodiments, the steering fastening structure 1 of the present invention can assemble the body 11 onto the object 10 and apply force to the operating part 12, so that the fastening part 13 can fasten or unfasten with the other object 20, thereby completing the rapid combination and separation of at least two objects, and achieving the purpose of repeated rapid combination and separation.

[0060] In one embodiment of the present invention, the body 11 is provided with a connecting part 111, through which the body 11 is securely combined with the object 10 by means of expansion, locking or welding, so as to facilitate the operation of the operating part 12 and the fastening part 13.

[0061] In one embodiment of the present invention, the body 11 is provided with an anti-rotation part 112, which forms an anti-rotation with the object 10. Through the cooperation of the assembly part 111 and the anti-rotation part 112, the body 11 and the object 10 can be stably combined, so as to facilitate the operation of the operating part 12 and the fastening part 13.

[0062] In one embodiment of the present invention, the body 11 is provided with a first limiting part 113 and a second limiting part 114, wherein the first limiting part 113 is located at a high position of the body 11, the second limiting part 114 is located at a low position of the body 11, and the first limiting part 113 and the second limiting part 114 are offset from each other (or connected). The operating part 12 moves to the first limiting part 113 to restrict it so as to drive the buckle part 13 to unfasten (or fasten), and the operating part 12 moves to the second limiting part 114 to restrict it so as to drive the buckle part 13 to fasten (or unfasten).

[0063] In one embodiment of the present invention, the operating part 12 is provided with a stop part 121. The operating part 12 moves longitudinally to make the stop part 121 move away from the first limiting part 113, and the operating part 12 rotates to the second limiting part 114, so that the operating part 12 drives the buckle part 13 to unfasten or fasten.

[0064] In one embodiment of the present invention, the operating part 12 is provided with a blocking part 121 and a clearance part 122. The clearance part 122 is connected to one side of the operating part 12, and the blocking part 121 is located inside the operating part 12 and corresponds to the clearance part 122. The operating part 12 moves longitudinally to move the blocking part 121 away from the first limiting part 113 of the body part 11, so that the clearance part 122 corresponds to the first limiting part 113. The blocking part rotates to move to the second limiting part 114 of the body part 11, and the first limiting part 113 enters the clearance part 122, so that the operating part 12 drives the fastening part 13 to fasten or de-fasten. In this way, the operating part 12 can drive the fastening part 13 to fasten or de-fasten the fastened part 201, so as to complete the rapid combination and separation of at least two objects, thereby achieving the purpose of repeated rapid combination and separation.

[0065] In one embodiment of the present invention, the fastening part 13 includes an assembly 131, which combines the operating part 12 and the fastening part 13. The assembly 131 can be bolted, fastened, locked, snapped, or threaded onto the operating part 12, allowing the operating part 12 to move the fastening part 13 as required by the cooperation of the assembly 131. This allows the operating part 12 to move longitudinally and then rotate, enabling the operating part 12 to fasten the fastening part 13 to the fastened part 201 of the other object 20 or to unfasten it from the fastened part 201 of the other object 20. Thus, the operating part 12 can drive the fastening part 13 to fasten or unfasten the fastened part 201, thereby achieving rapid engagement and disengagement of at least two objects, achieving the purpose of repeated rapid engagement and disengagement.

[0066] In one embodiment of the present invention, the fastening part 13 includes an assembly 131, a rod 132, and a fastening body 133. The assembly 131 combines the operating part 12 with the rod 132. The fastening body 133 is disposed on the rod 132, allowing the operating part 12 to cooperate with the assembly 131 to drive the rod 132, so that the rod 132 drives the fastening body 133 to fasten to the fastened part 201 of the other object 20, or to be unfastened by the fastened part 201 of the other object 20. Thus, the operating part 12 can drive the fastening part 13 to fasten or unfasten with the fastened part 201, thereby achieving rapid engagement and disengagement of at least two objects, and achieving the purpose of repeated rapid engagement and disengagement.

[0067] In one embodiment of the present invention, the avoidance portion 122 may be a space, a hole, a recess, a groove, or an open area, so that the avoidance portion 122 can meet different avoidance requirements.

[0068] In one embodiment of the present invention, the fastening body 133 may be a spring-loaded body, an externally threaded body, a column, an internally threaded body, an externally fastened body, or an internally fastened body. This allows the fastening body 133 to better meet the needs of practical applications.

[0069] Based on the above embodiments, when the steering fastening structure 1 of the present invention is used, the steering fastening structure 1 can be assembled onto the object 10 with the body 11. When using the steering fastening structure 1, a pressure can be applied to the operating part 12 first, causing the operating part 12 to move downward longitudinally, causing the stop part 121 to move away from the first limiting part 113, and causing the avoidance part 122 to correspond to the first limiting part 113. Then, a rotational force is applied to make the operating part 12 rotate, causing the stop part 121 to rotate to the second limiting part 114 of the body 11, and causing the first limiting part 113 to enter the avoidance part 122, so that the operating part 12 moves downward simultaneously due to the movement of the assembly 131, the rod 132 and the fastening body 133, thereby causing the operating part 12 to drive the fastening body 133 of the fastening part 13 to fasten to the fastened part 201 of the other object 20 via the object 10. Thus, the operating part 12 can drive the fastening part 13 to fasten with the fastened part 201, thereby completing the rapid combination of at least two objects.

[0070] Alternatively, a rotational force can be applied to the operating part 12 in the opposite direction, causing the stop part 121 of the operating part 12 to rotate and move away from the second restricting part 114, and simultaneously causing the assembly 131, the rod 132, and the fastening body 133 to rotate and move in the same direction, so that the avoidance part 122 aligns with the first restricting part 113. Then, the operating part 12 is lifted, causing the stop part 121 to move longitudinally and abut against the first restricting part 113, thereby causing the operating part 12 to move upward simultaneously, causing the fastening body 133 of the fastening part 13 to disengage from the other object 20 and unfasten. In this way, the operating part 12 can drive the fastening part 13 to unfasten the fastened part 201, thereby completing the rapid separation of at least two objects and achieving the purpose of repeated rapid engagement and disengagement.

[0071] In one embodiment of the present invention, the steering buckling structure 1 further includes an elastic component 14, which may be a torsion spring. The elastic component 14 is sleeved on the rod 132 of the buckle 13, and the two ends of the elastic component 14 are respectively connected to the body 11 and the operating part 12. After the operating part 12 moves longitudinally, the elasticity of the elastic component 14 drives the operating part 12 to rotate, thereby driving the buckling body 133 of the buckle 13 to buckle or unbuckle.

[0072] Based on the above embodiments, when the steering engagement structure 1 of the present invention is used, the steering engagement structure 1 can be assembled onto the object 10 with the body 11. At this time, the elastic component 14 can be in an elastically compressed state. When using the steering engagement structure 1, a pressure can be applied to the operating part 12 first, causing the operating part 12 to move downward longitudinally, causing the blocking part 121 to move away from the first limiting part 113, and causing the avoidance part 122 to correspond to the first limiting part 113. Then, the operating part 12 is moved downward due to the elastic component. The elastic release of component 14 automatically applies a rotational force, causing the operating part 12 to rotate and move. This allows the stop part 121 to rotate and move to the second limiting part 114 of the body 11 to form a stop, and the first limiting part 113 to enter the avoidance part 122. As a result, the operating part 12 moves downward simultaneously, causing the assembly 131, the rod 132, and the fastening body 133 to move downward. This allows the operating part 12 to drive the fastening body 133 of the fastening part 13 to fasten to the fastened part 201 of the other object 20 via the object 10. In this way, the operating part 12 can drive the fastening part 13 to fasten to the fastened part 201, thereby completing the rapid connection of at least two objects.

[0073] Alternatively, a rotational force can be applied to the operating part 12 in the opposite direction, causing the stop part 121 of the operating part 12 to rotate and move away from the second restricting part 114, and simultaneously causing the assembly 131, the rod 132, and the fastening body 133 to rotate, thereby allowing the elastic component 14 to return to its elastically compressed state, and aligning the avoidance part 122 with the first restricting part 113. Then, the elastic component 14 automatically lifts the operating part 12, causing the stop part 121 to move longitudinally and abut against the first restricting part 113, thereby causing the operating part 12 to move upwards simultaneously, causing the fastening body 133 of the fastening part 13 to disengage from the other object 20 and unfasten. In this way, the operating part 12 can drive the fastening part 13 to unfasten the fastened part 201, thereby completing the rapid separation of at least two objects and achieving the purpose of repeated rapid engagement and disengagement.

[0074] Please see Figures 9 to 11 As shown in the figure: In one embodiment of the present invention, the body 11 is provided with a first limiting part 113, a second limiting part 114 and a third limiting part 115, and a guide part 116 is provided between the first limiting part 113, the second limiting part 114 and the third limiting part 115. The operating part 12 is provided with a stop part 123. The stop part 123 is limited by the first limiting part 113 and the third limiting part 115 to prevent the operating part 12 from rotating. The first limiting part 113 and the third limiting part 115 serve as the turning limit of the stop part 123, thereby enabling the operating part 12 to achieve the effect of preventing rotation when not in use.

[0075] In one embodiment of the present invention, the two ends of the elastic component 14 are respectively disposed (interfering with or inserted into) the body 11 and the operating part 12, so as to cause the operating part 12 to automatically rotate (or automatically reciprocate) through the elastic component 14, so that the operating part 12 automatically rotates (or automatically reciprocates) between the first limiting part 113, the second limiting part 114, the third limiting part 115 and the guide part 116 of the body 11 with the cooperation of the stop part 121, so that the operating part 12 performs automatic rotation (or automatic reciprocating rotation).

[0076] In one embodiment of the present invention, the two ends of the elastic component 14 are respectively disposed (interfering with or inserted into) the body 11 and the operating part 12, so as to cause the operating part 12 to rotate elastically or reciprocate elastically through the elastic component 14, so that the operating part 12 rotates elastically (or reciprocates elastically) between the first limiting part 113, the second limiting part 114, the third limiting part 115 and the guide part 116 of the body 11 with the cooperation of the blocking part 121, so that the operating part 12 rotates elastically (or reciprocates elastically).

[0077] Based on the above embodiments, when the steering engagement structure 1 of the present invention is used, the elastic component 14 can be in a pre-existing elastically compressed state, and the stop portion 123 forms a limit between the first limiting portion 113 and the third limiting portion 115. When using the steering engagement structure 1, a pressure can be applied to the operating portion 12 first, causing the operating portion 12 to move downward longitudinally, causing the stop portion 121 and the stop portion 123 to move away from the first limiting portion 113, and allowing the avoidance portion 122 to align with the first limiting portion 113. Then, the operating portion 12 is released due to the elasticity of the elastic component 14. The automatic application of rotational force causes the operating part 12 to rotate, causing the stop part 121 and the stop part 123 to rotate simultaneously via the guide part 116. The stop part 121 moves to the second limiting part 114 of the body 11 to form a stop, while the first limiting part 113 enters the avoidance part 122. This causes the operating part 12 to move the assembly 131, the rod 132, and the fastening body 133 downwards simultaneously, allowing the operating part 12 to drive the fastening body 133 of the fastening part 13 to fasten to the fastened part 201 of the other object 20 via the object 10. In this way, the operating part 12 can drive the fastening part 13 to fasten to the fastened part 201, thereby completing the rapid connection of at least two objects.

[0078] Alternatively, a reverse rotational force can be applied to the operating part 12, causing the stop part 121 and the stop part 123 of the operating part 12 to rotate and move in opposite directions, and causing the stop part 121 to move away from the second limiting part 114, allowing the stop part 121 to move from the guide part 116 to the first limiting part 113, thereby driving the assembly 131, the rod 132 and the fastening body 133 to rotate simultaneously, thereby allowing the elastic component 14 to return to its elastically compressed state, and The avoidance part 122 is aligned with the first limiting part 113, and then the elastic component 14 automatically lifts the operating part 12, causing the blocking part 121 to move longitudinally and abut against the first limiting part 113, and the stop part 123 to move to form a limit between the first limiting part 113 and the third limiting part 115. This allows the operating part 12 to move upwards simultaneously, causing the fastening body 133 of the fastening part 13 to disengage from the other object 20 and unfasten. In this way, the operating part 12 can drive the fastening part 13 to unfasten the fastened part 201, thereby achieving rapid separation of at least two objects and achieving the purpose of repeated rapid engagement and disengagement.

[0079] In summary, the steering engagement structure of the present invention can apply force to the operating part to make the buckle engage or disengage, so as to complete the rapid engagement and disengagement of at least two objects, thereby achieving the purpose of repeated rapid engagement and disengagement.
