It can be understood that, in other embodiments, the socket cavity 11 can be opened by the rear member 20 , and correspondingly, the socket connector 21 is provided by the head member 10 , so as to achieve the above purpose. More specifically, as follows:

As shown in Figures 2 and 3, the plug connector 21 is provided with a separation channel 212 that is aligned with the push structure 13 along the insertion direction. The cantilever 21b, preferably, the first cantilever 21a is a left cantilever and the second cantilever 21b is a right cantilever, but not limited thereto; Each side has a hook 211, that is, the left side of the first cantilever 21a and the right side of the second cantilever 21b each have a hook 211; 21a and the second cantilever 21b swing away from each other, so that the hook 211 on the left side of the first cantilever 21a snaps into the side cavity wall 111 on the left side of the insertion cavity 11, and the right side of the second cantilever 21b The hook 211 on the side snaps into the side cavity wall 111 on the right side of the insertion cavity 11, that is, the plug joint 21 is fixed to the head member 10 from opposite sides, effectively preventing the plug joint 21 from falling off from the insertion cavity 11.
