Further, the bottom of described second spring holder has bulge loop, and the top of described second spring holder snaps in from the bottom of the first spring, and described bulge loop is resisted against the first spring bottom.
Further, the outer wall of described bulge loop abuts on the inwall of torsion shaft, and by the first spring and the second spring, the inwall of the second spring holder and torsion shaft is slidably matched.
Further, described torsion shaft has a through hole, and the top of described tap holder snaps in the through hole of torsion shaft, and by the first spring and the second spring, the top of tap holder and the inwall of torsion shaft is slidably matched.
Further, the quantity of described spacer pin is two, and the bottom of described torsion shaft is provided with two draw-in grooves snapped in for spacer pin, and described spacer pin snaps in the draw-in groove of torsion shaft.
Apply tap chuck provided by the utility model, its beneficial effect is: be provided with the first spring holder, the second spring holder, the first spring and the second spring in fixed cover, torsion shaft is provided with spacer pin, the top of torsion shaft insert brass bushing in, and the bottom of torsion shaft is resisted against on the outer wall of the bushing bottom of brass, by the elastic force of the first spring and the second spring, the moment of torsion of torsion shaft can be regulated to adapt to the tap holder of different moment of torsion, flexible and convenient to use and torque adjustment convenient.
