摘要： A power hammer has a handle mounted to a housing and capable of limited movement relative thereto. A hollow axle is attached to the housing and is rotatable between a first and second position and is biased towards the first position by a torsional spring which extends within the axle. Rotation of the axle causes rotation of arms connected thereto. Connectors are slidably mounted within guides and are respectively connected at one end to each of the arms and at the other end to the handle. Vibrations in the housing cause movement of one end of the handle, which causes movement of the associated connector and arm. Movement of the one arm causes rotation of the axle, which therefore causes movement of the other arm and connector, and the other end of the handle. Thus, the movement of one end of the handle is coupled to the other end.

摘要： A power tool has a handle capable of limited movement mounted to its housing. An axle is rotatably connected to the housing and is movable between a first and second positions and is spring biased towards the first position. Arms are connected to and rotate with the axle. Connectors are slidably mounted within guides and are connected at one end to the arms and at the other end to the handle. Vibrations in the body of the power tool cause movement of one end of the handle, which causes movement of a connector and in turn movement of an arm. Movement of the arm causes rotation of the axle which therefore causes movement of the other arm. This in turn causes the related connector to slide within its guide and move the other end of handle. Thus, movement of one end of the handle is coupled to the other end.

摘要： A power tool has a handle assembly which is biased by a torsional spring. The torsional spring has an engaging arm the position of which is fixed relative to the housing by an adjusting mechanism. The adjusting mechanism has a lever which extends outside the housing of the power tool, and a cam surface, and is mounted on and rotatable at least partially around an axle. In use, the tension in the torsional spring may be adjusted by movement of the lever. The lever is moved, causing rotation of the adjusting cam around the axle. As a result, the cam surface causes the engaging arm of the spring to be moved axially along the axle and more or less tension is applied to the torsional spring.

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.
