Embodiment Construction

[0015] According to FIG. 1, a hand-held power tool 1 in the form of a percussion and rotary combined hammer along an percussion axis A has a guide handle 4 that is vibration-decoupled from a percussion hammer part 2 with a rotatable and The operation mode selector switch 3 (Fig. 2) for the rotary movement of the percussion rotary drilling mode and the percussion-only rock drilling mode. A motor switch 5 for motor control is arranged in the guide handle 4, and the motor switch is turned on by means of a locking switch 7 in the form of an axially and longitudinally movable slider arranged on the upper handle retainer 6. status can be locked.

[0016] According to FIG. 2 , with the operating mode selector switch 3 switched on in the rock drilling operating mode, a switch lever 9 is moved axially on the hammer side via an eccentric disk 8 , so that a stop 10 does not protrude into the switch of the locking switch 7 Area X, so that the locking switch can be moved far enough on the...

Abstract

The invention relates to a rotary-percussion hand-held power tool capable of applying blows along a percussion axis (A) includes a percussion mechanism assembly (2) with a mode selection switch (3), a guide handle (4) vibrationally decoupled from the percussion mechanism assembly (2) and with a motor switch (5) for turning a power tool motor on and off, a locking switch (7) for locking the motor switch and displaceable in a switching region (X), and a switching linkage (9) displaceable by the mode selection switch (3) and having a stop (10) displaceable during a drilling operational mode into the switching region (X) of the locking switch (7), with the switching linkage (9) having two legs (16a, 16b) extending at an angle to each other, and with one of the legs (16a), which is more stiff and forms the stop (10), being pivotally supported on the percussion mechanism assembly (2), and another of the legs (16b), which extends axially and is flexural, being connected with the mode selection switch (3).

Description

technical field [0001] The invention relates to an at least partially percussive and rotary hand-held power tool, such as a combination hammer, having a locking switch for switching a motor in rock drilling mode. Background technique [0002] In hand power tools of this type striking and rotating along the striking axis, the guide handle is vibration-decoupled from the striking hammer part. For the pure percussion rock drilling operating mode, the motor switch of the control motor is generally locked with a locking switch in the on state, but it is not suitable for other operating modes that also have rotation. Furthermore, percussion hammer part is also to be understood as a combined electric motor / percussion hammer part or a combined electric motor / gear part. [0003] According to DE10034768, the guide handle is designed to be vibration-decoupled from the hammer part. The locking switch for the motor switch is designed as a multi-piece hingedly supported stop clip in the...
