摘要： A power tool for chiseling and drilling includes a housing, a motor disposed inside the housing, and a pneumatic percussion mechanism. An operation mode selector switch is disposed on the housing and has a first operation mode setting and a second operation mode setting where the first operation mode setting activates the pneumatic percussion mechanism and the second operation mode setting deactivates the pneumatic percussion mechanism. A valve has an inlet-port formed inside the guiding tube and an outlet-port formed outside the guiding tube where the valve is connected to the operation mode selector switch. The valve is closed in the first operation mode setting which disables an air exchange between the inlet-port and the outlet-port and the valve is open in the second operation mode setting which enables the air exchange between the inlet-port and the outlet-port.

摘要： The hand-held power tool has a tool socket, a motor and a pneumatic striking mechanism. The striking mechanism has an exciter driven by the motor along a working axis, a striker coupled to the exciter via an air cushion, and an intermediate striker arranged between the striker and the tool socket in the striking direction. The striking mechanism also has a guide in which the intermediate striker is guided. The guide has a first sliding surface that guides a first section of the intermediate striker, and a second sliding surface that is arranged offset relative to the first sliding surface in the striking direction and that guides a second section of the intermediate striker. A radial dimension of the first section of the intermediate striker is greater than a radial dimension of the second section of the intermediate striker.

摘要： It is an object of the invention to reduce transmission of an external force caused by run-out of a tool bit to a tool body in a power tool is provided. A representative power tool which performs a predetermined operation by linear motion of a tool bit in its axial direction has a tool body, a tool holder that holds the tool bit in its front end region and extends in the axial direction of the tool bit, and an elastic element. A rear region of the tool holder opposite from the front end region extends into the tool body, and in the extending region, the tool holder is coupled to the tool body such that the tool holder can rotate about a pivot on a z-axis defined by an axis of the tool bit, in directions of y- and x-axes which intersect with the z-axis. The elastic element applies a biasing force to the tool holder in such a manner as to hold the tool holder in a predetermined position or an initial position with respect to the tool body.

摘要： A rotary hammer includes a motor, a spindle coupled to the motor for receiving torque from the motor, a piston at least partially received within the spindle for reciprocation therein, a striker received within the spindle for reciprocation in response to reciprocation of the piston, and an anvil received within the spindle and positioned between the striker and a tool bit. The rotary hammer also includes a retainer received within the spindle for selectively securing the striker in an idle position in which it is inhibited from reciprocating within the spindle, and an O-ring positioned between the retainer and the spindle. The O-ring is disposed around an outer peripheral surface of the anvil. The O-ring is compressible in response to the striker assuming the idle position. The compressed O-ring imparts a frictional force on the outer peripheral surface of the anvil to decelerate the anvil.
