Abstract

A hand-held power tool includes a housing in which a drive unit and an impact-mechanism unit are arranged. The hand-held power tool further includes a tool-receiver interface configured to releasably connect with a tool receiver, the tool receiver configured as a stirrer-basket receiver. A user interface is configured to set at least one of a rotary-hammer mode and a stirring mode for the hand-held power tool.

First claim

What is claimed is:

1. A hand-held power tool, comprising:
a housing in which a drive unit and an impact-mechanism unit are arranged;
a tool-receiver interface;
a tool receiver configured as a stirrer-basket receiver that is releasably connectable to the tool-receiver interface; and
a user interface having an input unit via which an operating mode of the hand-held power tool is selected from a plurality of operating modes, the plurality of operating modes including at least one rotary-hammer mode and at least one stirring mode,
wherein, in the at least one stirring mode, the hand-held power tool is configured to operate the drive unit for a prespecified stirring time without an operating switch being actuated.

2. The hand-held power tool according to claim 1 , wherein the at least one rotary-hammer mode and the at least one stirring mode have different idling rotational speeds.

3. The hand-held power tool according to claim 1 , wherein the at least one rotary-hammer mode and the at least one stirring mode have different working rotational speeds.

4. The hand-held power tool according to claim 1 , further comprising:
a battery interface configured to connect to a battery pack.

5. The hand-held power tool according to claim 1 , further comprising:
a communication unit configured to communicate with an external device.

6. The hand-held power tool according to claim 5 , wherein the communication unit is configured to communicate wirelessly with the external device.

7. The hand-held power tool according to claim 1 , wherein the input unit is arranged on one of the housing of the hand-held power tool and an external device.

8. The hand-held power tool according to claim 1 , wherein the user interface is further configured to sense at least one of the tool receiver and an insert tool received in the tool receiver.

9. The hand-held power tool according to claim 1 , wherein the stirrer-basket receiver includes a screw thread configured to connect to a stirrer basket.

10. The hand-held power tool according to claim 1 , further comprising:
an impact-mechanism control configured such that connection of the stirrer-basket receiver in the tool-receiver interface mechanically disables the impact-mechanism unit.
