When the battery is full of electricity, the self-tapping screw can be used for about 2-3 hours. The specific use time depends on the hardness of the actual material and the size of the screw, for reference only. machine unscrew screws and boreholes provide torque optimization. Large torque, low speed, suitable for screw. Low torque, high speed, suitable for drilling. The 1-20 on the fuselage is 20 block torsion adjustment, indicating the size of the machine screw force, the greater the number, the greater the force, the smaller the 20 force. The machine with torsion adjustment can achieve better screw effect.

电池满电状态下，拧自攻螺丝大约可以使用2-3小时，具体的使用时间取决于实际被拧材质的硬度以及螺丝的大小，仅供参考哦。 机器起拧螺丝和钻孔提供的扭矩优化。1档扭力大，转速低，适合拧螺丝。2档扭力小，转速高，适合钻孔。机身上的1-20是20挡扭力调节，表示机器拧螺丝力暈的大小，数字越大力暈越大，1力量小20力量大。带扭力调节的机器可以实现更好的拧螺丝效果。
