Abstract

An electric machine tool includes a first actuating device and a second actuating device. The second actuating device is arranged at a distance from the first actuating device. The first actuating device is mechanically connected to the second actuating device by a switching connector which is configured to be loaded in tension only.

First claim

The invention claimed is:

1. An electric machine tool, comprising:
a first actuating device;
a second actuating device arranged at a distance from the first actuating device;
a switching connector configured to mechanically connect the first actuating device to the second actuating device, the switching connector configured to transmit only tensile load between the first and second actuating devices;
a tool housing; and
an anti-vibration handle casing supported on the tool housing by an elastic connecting mechanism, wherein;
the first actuating device is disposed in the tool housing,
the second actuating device is disposed in the handle casing, and
the switching connector is adapted and arranged to bear against the elastic connecting mechanism and does bear against the elastic connecting mechanism while tensile load is transmitted by the switching connector.

2. The electric machine tool as claimed in claim 1 , wherein:
the switching connector has a first end and a second end, the first end is fixed to the first actuating device, and
the second end is fixed to the second actuating device.

3. The electric machine tool as claimed in claim 1 , wherein:
the switching connector is configured such that the first actuating device is adjustable by adjustment of the second actuating device and
the second actuating device is adjustable by adjustment of the first actuating device, when the switching connector is subjected only to tensile load.

4. The electric machine tool as claimed in claim 1 , wherein the switching connector has an invariable length.

5. The electric machine tool as claimed in claim 1 , wherein the switching connector is one of a band, a wire, and a stamped bent part.

6. The electric machine tool as claimed in claim 1 , wherein:
the elastic connecting mechanism is configured to stretch to a stretched length when supporting the tool housing, and
the stretched length of the elastic connecting mechanism is constant.

7. The electric machine tool as claimed in claim 1 , wherein the elastic connecting mechanism is a leaf spring.

8. The electric machine tool as claimed in claim 1 , wherein the first actuating device includes an operating mode switch, configured to switch the electric machine tool between at least two operating modes.

9. The electric machine tool as claimed in claim 1 , wherein the second actuating device is a locking device configured to fix a switching device in a switch-on position and a switch-off position.

10. The electric machine tool as claimed in claim 2 , wherein the first actuating device includes a slide bar, configured to adjust in a sliding direction to switch the electric machine tool between at least two operating modes.

11. The electric machine tool as claimed in claim 10 , wherein the first end of the switching connector is fixed to the slide bar.

12. The electric machine tool as claimed in claim 10 , wherein the slide bar is configured to be displaced to switch the electric machine tool between further different operating modes.
