摘要： A hand held motor driven electrically powered tool, in particular a rotary hammer, comprising a spindle (40) for rotatingly driving a tool or bit (68), a spindle rotary drive train (14, 5, 10) for rotatingly driving the spindle (40) and an arrangement for detecting blocking events (16, 17). Blocking events occur when the tool or bit of the tool become rotationally fixed in the material being bored in which case the rotary drive on the spindle from the motor causes the tool housing to rotate in a user's grip. According to a first aspect of the invention an overload clutch (14) is provided in the spindle rotary drive train for transmitting rotary drive to the spindle below a predetermined torque and slipping above the predetermined torque arranged such that the overload clutch cuts off rotary drive to the spindle, for example by reducing the predetermined torque at which the overload clutch (14) slips when a blocking event is detected so as to cut off rotary drive to the spindle in response to a blocking event being detected. According to a second aspect of the invention there is provided a mode change mechanism (45, 47, 49, 43) for selectively disengaging a clutch (10, 7) so as to cut off the rotary drive to the spindle (40) and the clutch is disengaged when a blocking event is detected so as to cut off rotary drive to the spindle in response to a blocking event being detected.
摘要翻译：一种手持马达驱动的电动工具，特别是旋转锤，包括用于旋转地驱动工具或钻头（68）的主轴（40），用于旋转地驱动主轴的主轴旋转传动系（14,5,10） 40）和用于检测阻塞事件（16,17）的装置。当工具的工具或钻头被旋转地固定在钻孔材料中时，发生堵塞事件，在这种情况下，来自马达的主轴上的旋转驱动器使得工具壳体在使用者的把手中旋转。根据本发明的第一方面，一种过载离合器（14）设置在主轴旋转传动系中，用于将转动驱动传递到预定转矩以下的预定转矩，并且在预定扭矩以上滑动，使得过载离合器将旋转驱动器切断主轴，例如通过减小当检测到阻塞事件时过载离合器（14）滑动的预定扭矩，以便响应于检测到阻塞事件而切断到主轴的旋转驱动。根据本发明的第二方面，提供了一种用于选择性地分离离合器（10,7）以便切断到主轴（40）的旋转驱动器的模式改变机构（45,47,49,43），并且当检测到阻塞事件时，离合器分离，以便响应于检测到阻塞事件而切断到主轴的旋转驱动。

摘要： A fastening device that drives one or more fasteners into a workpiece generally includes a tool housing and a multistage solenoid contained in the tool housing. The multistage solenoid includes an armature member that travels through at least a first stage, a second stage, and a sense coil disposed therebetween. A driver blade assembly includes a blade member connected to the armature member. The driver blade assembly is operable between an extended condition and a retracted condition. A control module determines a position of the armature member relative to at least one of the first stage and the second stage based on a signal from the sense coil. The trigger assembly is connected to the control module and partially contained within the housing. The trigger assembly is operable to activate a driver sequence that moves the driver blade between the retracted condition and the extended condition. The control module adjusts a force imparted on the armature by at least one of the first stage, the second stage, and a combination thereof based on the signal from the sense coil.
