In this way, the assembly portion 11 can be combined with the object 10, and the buckle portion 12 can be fastened to the other object 20 or unfastened from the other object 20 in cooperation with the limiting member 13 to complete the rapid connection and separation of at least two objects, thereby achieving the purpose of repeated rapid connection and separation.

This allows the fastening structure 1 of the present invention to better meet practical application requirements.

[0077] See also Figures 13 to 15 In addition to the above embodiments, in one embodiment of the present invention, the difference from the above embodiments is that the number of the positioning portion 121 is one, and the limiting member 13 moves away from the positioning portion 121 at the moving portion 122, so that the buckling portion 12 is in a normal buckling position or a normal open position, so that the buckling portion 12 is automatically buckled or automatically unbuckled due to the elastic force of the second elastic component 16, or so that the buckling portion 12 is buckled or unbuckled with the positioning portion at the moving portion 122; for example: when unbuckled, the second elastic component 16 forms a compressed state, and then it is automatically buckled due to the elastic force recovery when buckled.

[0078] See also Figures 16 and 17 Based on the above embodiment, when in use, the limiting member 13 can be pressed down to compress the first elastic component 15, so that the non-limiting portion 132 moves downward and breaks away from the restriction of the positioning portion 121, and the non-limiting portion 132 is located at the position of the positioning portion 121, and at the same time, the non-limiting portion 132 corresponds to the movable portion 122, and when a force is applied to pull or push the operating portion 123, the non-limiting portion 132 can move on the movable portion 122, and at the same time, the second elastic component 16 is compressed to make the fastening portion 12 fasten the other object 20, and after fastening, one side wall of the movable portion 122 corresponds to the non-limiting portion 132, and due to the elastic force of the first elastic component 15 recovery, the limiting portion 131 moves up to one side wall of the movable portion 122 for limiting, so as to complete the fastening of the other object 20.
