"Chainsaw"

The price increase affects a chainsaw with an endless, revolving Chain that has saw teeth, preferably a motorized sword saw and this is essentially characterized by the fact that the motor chain sword saw has several Has a comb-like, the saw teeth protruding holding fingers as an abutment for the material to be cut, preferably furthermore, the holding fingers are arranged approximately plane-parallel to the cutting plane of the saw teeth and preferably furthermore in each case stand perpendicular to the longitudinal extension of the chain

Thanks to these measures, thin branches, for example also from hedges, can now be conveniently sawed off with a power chain saw because the holding fingers, which grip between the branches of the bushes when sawing, prevent the branches from bending away when Safe prevention of sawing now

Furthermore, the innovation is characterized in that the above-described Object the holding fingers are preferably releasably attached to the sword.

In this way, the innovation item can not only be used both for sawing thin branches and for example can be used for felling trees, but there is now also the possibility of replacing the holding fingers »

Another advantageous and inventive feature of the above The object consists in the fact that the depth of engagement of the retaining fingers protruding beyond the saw teeth is approximately the same as the distance corresponds to two adjacent holding fingers

In a preferred and inventive way, the holding fingers are in terms of their depth of engagement and preferably also provided adjustable and lockable with respect to their distance from one another

As a result, the number of holding fingers serving as an abutment for the material to be cut can also match the respective dimensions of the material to be cut, so that the performance of the innovation is further increased.

Furthermore, an advantageous and inventive embodiment is characterized in that the above-described subject the fingers have a common holder that can be detachably connected to the sword.

A variant of the above-described variant that is preferred and inventive, extremely economically producible under certain circumstances Object consists in the fact that the fingers

le of your bracket that can be detachably connected to the sword are

In the drawing, the subject of the innovation is in one embodiment shown.

They show: Fig.i a motorized sword saw in the front view,

Fig, 2 also in section A-B of Iig.1.

Here are on the strutting from the engine 1 sword 2 as a guide for a with saw teeth 3 equipped endless, circumferential Link chain 4 holding fingers 5 provided when sawing off relatively thin branches »for example of a bush, reaching into the latter and protruding into the finger gaps Hold branches. These fingers 5 »their free ends 6 are sharpened, are cut, material-specific parts a steel plate 7t which is detachable with screws 8 on the sword 2 is attached.
