The buckle device 3 can also be assembled on the pivot portions 1141 of the base block 11 or on the limiting pivots 1422 of the cover shell 142 independently in a swinging state. Such simple equal changes and modifications do not limit the scope of protection of the present invention. Such simple equal changes and modifications should still be included in the patent scope covered by the present invention.

In addition, in the application of the present invention, when the present invention is unlocked multiple times, if the pull strap 23 is detached or broken at the joint, a flat preset hand tool or preset tool can be inserted into the opening 22 and then pushed backward to produce the same unlocking method as pulling the pull strap 23, so as to disconnect the connector 1 from the electrical connection of the socket connector 4.

In addition, the main feature of the present invention is that when the pull strap 23 is pulled, the resisting elastic pieces 323 can be elastically deformed to link the hook portions 321 of the two arms 32 to elastically deflect downward by a distance. This achieves the effect of the base block 11 of the connector 1 forming a stable connection with the corresponding socket connector 4 and ensuring the movement.

The above description is only the preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Therefore, all simple modifications and equivalent structural changes made by using the description and drawings of the present invention shall be included in the patent scope of the present invention and shall be clearly stated.
