摘要： A rail has a guide surface on which the locking block is guided in a bearing manner between a position locking the bar, in which the toothed side engages in the toothed long side, and an unlocked position, in which the toothed side is not engaged with the toothed long side. A spring pretensions the locking block into the locking position. The guided side and/or the guide surface have a flank that is inclined with respect to the bar axis such that the locking block is forced in the direction of the bar in the event of a movement along the bar axis.

摘要： The handheld power tool has a tool receptacle for accommodating a tool on a working axis (11) and an electric motor (5). A pneumatic percussion mechanism (6) has an exciter, which is moved back-and-forth by the motor (5) periodically in parallel to the working axis (11), a striker (14), which is movable on the working axis (11) and is coupled via a pneumatic spring (18) to the exciter, and an anvil (19), which is situated movably on the working axis (11) and is situated downstream from the striker (14) in the percussion direction (12). The anvil (19) has a cylindrical anvil section (22) having a diameter and multiple channels (30) extending over the entire length (31) of the anvil section (22). A cross-sectional area of the anvil section (22) is at most 5% less than a circular area defined by the diameter.

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.
