To setting, extend to the tail end of the round needle body；Spring is installed at the rear portion of the round needle body, the spring with it is described
Round needle body is coaxially disposed；A part for the spring is sticked in the helicla flute, another part of the spring stretch out from
The tail end of the round needle body stretches out.
As a kind of preferred scheme of the present utility model, engaging stopper slot is provided with the round needle body；The card
It is axially arranged along the round needle body to close stopper slot；The engaging stopper slot be located at the annular silver coating and the helicla flute it
Between.
As a kind of preferred scheme of the present utility model, the round needle body is made up of copper material.
As a kind of preferred scheme of the present utility model, the needle surface is surface-treated, and strengthens the table of the needle point
Surface intensity.
As a kind of preferred scheme of the present utility model, the thickness of the annular silver coating is 0.2-0.5mm.
Pass through above-mentioned technical proposal, the beneficial effect of technical solutions of the utility model are：The utility model is rational in infrastructure,
The tail end of round needle body sets spring, round needle body is axially had certain retractility, during progress grafting, both companies of can guarantee that
The stability connect, while and can avoids round needle body from bending, stable connection, service life length；The utility model is in round needle
Annular silver coating is set on body, to improve the electric property of round needle body, while rubbing during and can reduction round needle body grafting
Power is wiped, improves the fluency of round needle body grafting, using effect is good.
