摘要： A mechanism for locking and cushioning a spindle of a power tool includes a driving disk, a combination of a cam and a plurality of elastic components, and a plurality of roller pairs. The combination of the cam and the elastic components is accommodated in a body. The driving disk is disposed at one end of the body and in contact with the cam. A surface of the driving disk is formed with a plurality of stopping blocks inserted into the body to contact the elastic components, respectively. The roller pairs are respectively disposed between two adjacent stopping blocks and in contact with an inclined surface of an outer surface of the cam. When the power tool is powered off, relative movements between the elastic components and the stopping blocks and pressing forces between the inclined surface of the cam and the roller can cushion and lock the spindle.

摘要翻译： 用于锁定和缓冲电动工具的心轴的机构包括驱动盘，凸轮和多个弹性部件的组合以及多个辊对。 凸轮和弹性部件的组合容纳在主体中。 驱动盘设置在主体的一端并与凸轮接触。 驱动盘的表面形成有分别插入到主体中以与弹性部件接触的多个止动块。 辊对分别设置在两个相邻的止动块之间并且与凸轮的外表面的倾斜表面接触。 当电动工具断电时，弹性部件和止动块之间的相对运动以及凸轮和滚子的倾斜表面之间的压力可以缓冲并锁定主轴。

摘要： A torque system of a power tool includes a combination of a first body and a second body, in which a toothed ring is assembled; and a mode selecting assembly, a torque adjusting module and control pins disposed on the second body. The torque system further includes restricting mechanisms formed on the second body, and the control pins are respectively disposed in the restricting mechanisms. One side of the control pin has a stopper block, and the restricting mechanism includes a first stopper, a second stopper and a through hole. When the control pin is driven to rotate and the stopper block faces the first stopper or the through hole, the object of switching each operation mode is achieved.
