In addition, as shown in fig. 4 and 6, the width of the wire clamping portion 2032 is smaller than the diameter length of the lower arc wire groove. Because the diameter of the arc groove is adapted to the wire diameter of the cable connection wire, and the width of the wire clamping portion 2032 is smaller than the diameter and the length of the lower arc groove, the width of the wire clamping portion 2032 may be smaller than the wire diameter of the cable connection wire, so that the cable connection wire may be clamped, and after the connection wire is deformed and tightly clamped in one step through the V-shaped groove 2033 by matching with the pressure applied by the wire pressing block 101, the cable connection wire may be further clamped and fixed. In addition, because the cable connection wire is bent downwards and deformed under the pressure action of the line pressing block 101, the upper shell 10 and the lower shell 20 can be better buckled, and gaps which are generated by the fact that the upper shell 10 and the lower shell 20 cannot be completely buckled are avoided.
