[0027] Please refer to Figures 1-4 As shown, in this embodiment, the two opposite ends of the sleeve 11 are respectively provided with a first port 111 and a second port 112; the needle 12 movably penetrates through the sleeve 11 through the first port 111, and it can move in the sleeve 11 along the extending direction of the first port 111; one end of the tail plug 13 is riveted and fixed on the second port 112. Specifically, a limiting step 113 is arranged around one side of the sleeve 11 close to the first port 111, and the movement of the needle 12 in the sleeve 11 is limited by the limiting step 113, so as to prevent the needle 12 from falling out of the sleeve 11.

[0028] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, in this embodiment, the needle 12 includes a clamping part 121 and a contact rod 122.
