    • In view of the above problem, the present invention is to provide an electrical power tool which enables a user to intuitively grasp a rotation direction and a rotation speed of a tip tool. The electrical power tool 1 comprises a chuck 2 provided at a tip of a tool body 3, and rotatable with a tip tool held, and an operation switch 7 having operation protrusions 6 exposed to both side surfaces of a tool body 3 so as to be able to operate, respectively bilaterally symmetrically protruded with a rotation axis of the chuck 2 therebetween, coaxially rotatable with the chuck 2, and urged so as to be self-restored to a neutral position. The chuck 2 is rotated in a direction according to a rotation direction of the switch 7 at a speed according to a rotation angle from the neutral position of the operation switch 7.
    • 鉴于上述问题,本发明提供一种能够使用户直观地掌握尖端工具的旋转方向和旋转速度的电动工具。 电动工具1包括设置在工具主体3的尖端处并且能够保持尖端工具可旋转的卡盘2和具有暴露于工具主体3的两个侧表面的操作突起6的操作开关7, 能够与卡盘2的旋转轴分别左右对称地突出,与卡盘2同轴旋转,并被推压使其自恢复到中立位置。 卡盘2沿着与开关7的旋转方向相对于从操作开关7的中立位置的旋转角度的速度沿着该方向旋转。

    • A trigger switch has a stationary contact and a moving contact provided inside a body and able to come close to and away from each other a contact drive member accommodated slidably inside the body to drive the moving contact, and an operating shaft having a first end engaging with the contact drive member and a second end which projects from the body, having a trigger configured to be operated by a user. Clearance is provided between the first end of the operating shaft and the contact drive member upon engagement, which enables inclination of the operating shaft relative to the contact drive member.
    • 触发开关具有固定触点和设置在主体内部并能够靠近和远离彼此的可移动触点,所述触点驱动构件可滑动地容纳在主体内部以驱动移动触点;以及操作轴,其具有第一端接合 与触头驱动构件和从主体突出的第二端,具有构造成由使用者操作的触发器。 在接合时,在操作轴的第一端和接触驱动构件之间提供间隙,这使得操作轴相对于接触驱动构件能够倾斜。
