  • a high assembly cost is still required due to the complexity.
  • Especially the setting of the different operating modes requires a high mechanical effort.
  • a hammer drill with chisel function in which different operating modes are switchable by means of a slide switch.

  • the invention is based on the idea to provide a preassemblable unit in the form of a synchronization and switching unit for a knob for switching different modes of operation, on the one hand has a locking element, with a rotating with the tool spindle part, in particular the driven gear to realize a chisel function can be held, and on the other hand provided with a switching plate with switching curve for converting a rotational movement of the rotary switch in an axial movement for switching different operating modes.
  • the installation of a power tool, which is equipped with a inventive, preassembled unit is compared to the assembly of known power tools significantly simplified because the components, such as locking element and shrouds not individually bolted to the housing or must be used in special guides in the housing.
  • eccentric cams are arranged on the rotary switch with respect to the axis of rotation of the rotary switch, which cooperate with the switching curves of the shifters.

If the output gear wheel can not be brought into engagement with the drive gear of a countershaft because of its angular position, the rotary switch can still be rotated into the corresponding position due to the design according to the invention. Once the rotary drive is turned on, the driven gear snaps into meshing engagement with the drive gear of the countershaft due to the axial spring loading. In the same way, the connection and disconnection mechanism for the percussion drive can be synchronized if the switching plate provided for the circuit of the percussion drive is designed to be axially spring-loaded.
  • the shifters are forced out only in one direction of movement, so that a switching of the knob regardless of the angular position of the gears or coupling elements to each other, is possible.

  • the locking teeth are arranged symmetrically with respect to a central axis which is perpendicular to a longitudinal axis of the guide rod. This ensures that the locking element is acted upon symmetrically with respect to the guide rod and can not be twisted or tilted against it.
  • a headband may be provided which fixes the shift plate in the drilling position and thus holds the drive gear in its position.

  • the retaining clip 41 has a securing leg 44, which engages around the switching plate 5 in a front abutment region 45. In this position, it is thus ensured that the slip clutch 39 is positively held in position via the groove 40 with the leg 8 of the control panel 5. Without such Retaining clip 41, the friction clutch 39 is merely frictionally held by the coil spring 18 on the locking ring 25, so that in the case of shock stress there is a risk that the output gear 38 comes out of engagement. An increase in the spring force to reduce this risk is eliminated because otherwise the switching forces are too high.
