The invention also relates to an electric hand tool according to the type of the main claim. When drilling with a drill hammer, a so-called handle or motor handle is ideal for controlling the torque, which is created by the friction to catch the drill in the hole. However, such a handle is less suitable for chisel work with a drill bit. It is known that a so-called spade handle can be used for chisel work with such drill bits instead of the handle, whereby two different handles are used for drilling and hammering. However, this is cumbersome and not entirely safe, since the operator cannot absorb the torque when drilling with a non-adjusted spade handle and can therefore cause damage.

Advantages of the invention

The inventive hand tool with the characteristic features of the main claim has the advantage that the drill handle basically remains fixed and the second handle

can be mounted either permanently or additionally to the existing drill handle if required. Another advantage is that the second band handle can be swivelled just like the first handle.

Further advantages of the invention emerge from the sub-addresses and the following description.

drawing

An exemplary embodiment is explained in more detail in the description and drawing. The latter shows a side view of the front part of the electrical tape tool in Figure 1 and a side view of the same in Figure 2.

Description

In Figure 1, the front part 10 of a drill chuck can be seen, which has a cylindrical section 11 behind the drill chuck. On this part there is a lockable holder 12 which can be pivoted and runs transversely to the drill drive axis and has a flange. A handle 14 is attached to this in the same axis as the base 13. Between the handle 14 and the base 13 there is a cross member 15 which is arranged vertically around the handle 14 and to which a further handle 16 is attached which runs parallel to the handle 14 but in the opposite direction. The cross member 15 is pivotably attached to the base 13 and can be adjusted with the aid of the flange. a basting device 17, one part of which is located on the foot 13, the other on the handle 14 (counter-locking device) can be swiveled into any position and locked in a form-fitting manner by tightening the handle 14. The handle can be brought into any position by means of the swiveling holder 12 and the swiveling cross member 15. It is expedient to arrange the handle 16 so that it can be separated from the cross member IS.

When the handlebar is mounted on the left-hand side 14 (bottom handle), while the handlebar 16 (bottom handle) is only attached to the handlebar, due to its elastic arrangement it is also able to absorb vibrations.
