In addition to the above embodiments, in the engaging connection method of the present disclosure, the engaged object 20 is horizontally or rotationally inserted into the connector 101, while the fit engaging mechanism 12 coordinating with the base 11 is used to fit engage and limit or limit the engaged object 20.

In addition to the above embodiments, in the engaging connection method of the present disclosure, the engaged object 20 is first fit engaged and limited or limited by the fit engaging mechanism 12 coordinating with the base 11, and is then horizontally or rotationally inserted into the connector 101.

To put to the engaging connection structure 1 of the present disclosure to use, the base 11 can be fixed at the object 10, the engaged object 20 is assembled at the connector 101, and then the fit engaging mechanism 12 is engaging connected to one end of the engaged object 20. Once engaging connected to the engaged object 20, the fit engaging mechanism 12 can be limited by the base 11, such that the fit engaging mechanism 12 can securely engaging connect the engaged object 20.

To remove the engaged object 20, the base 11 is caused to release the fit engaging mechanism 12, so that the fit engaging mechanism 12 can separate and release the engaged object 20 to remove the engaged object 20 from the connector 101, thereby completing quick coupling and separation of at least two objects and hence achieving the effect of repeated quick coupling and separation.

In addition to the embodiments above, in one embodiment of the present disclosure, the base 11 is provided with at least one assembly portion 111, which is for the base 11 to be assembled at the object 10. In this embodiment, the number of the assembly portion 111 is two, which are respectively disposed on two ends of the base 11. Moreover, the assembly portion 111 is provided with a screw lock portion 112, which coordinates with a fixing element 113 for the base 11 to be assembled at the object 10.
