The conductive metal block 12 is fixed on the inner bottom surface of the shell 11 and is positioned at one side of a circular through hole on the bottom surface of the shell 11.
One end of the wire 13 is connected to the conductive metal block 12.
As shown in fig. 4, the positioning assembly 14 includes: a pressing block 141, a sliding groove 142 and a sliding block 143.
The pressing block 141 is arranged inside the shell 11 and is positioned above the circular through hole on the bottom surface of the shell 11, wherein the pressing block 141 partially covers the circular through hole on the bottom surface of the shell 11.
The sliding groove 142 is a curved through hole of the pressing block 141 downward along the top surface, the sliding groove 142 is divided into two sections, one section is close to a vertical wall surface of the housing 11, the other section is close to a circular through hole of the housing 11, and the two sections of sliding grooves 142 are communicated through the inclined through hole.
One end of the sliding block 143 is fixed on the bottom surface of the pressing block 141, and the other end is sleeved in the sliding groove 111.
