The tube is moved by a rotating grooved cylinder (3), inserted in the tube (2), driven by an electric motor (4). The cylinder transforms its rotational movement into to and fro movement by cooperating with a groove inclined on an axis of the cylinder cooperating with a screw (7) on the tube.

Description

La présente invention concerne un outil de coupe très réduitThe present invention relates to a very reduced cutting tool

d'encombrement, pouvant tenir dans la main. of space, being able to hold in the hand.

s II s'agir d'une petite scie électrique pour couper notamment: Bois, métaux, PVC, etc.... s It is a small electric saw to cut in particular: Wood, metals, PVC, etc ....

Dans le bricolage, comme dans les métiers du bâtiment, certains endroits sont difficiles d'accès (Exemple: travaux sous évier). In DIY, as in the building trades, some places are difficult to access (Example: work under sink).

Cette petite scie autorisera des coupes sur place à dimension, divers travaux d'établi, elle pourra remplacer la lame de scie, que l'on tient à la main et qui s'utilise difficilement, où avec un porte lame, peu pratique lorsque la lame se plie où se brise, au risque de se blesser. This small saw will allow cutting on the spot to size, various bench work, it can replace the saw blade, which is held by hand and which is used with difficulty, where with a blade holder, impractical when the blade bends where it breaks, at the risk of getting hurt.

Elle sera très pratique pour des travaux à main levée. It will be very convenient for freehand work.

Dans l'art antérieur, il est connu d'utiliser des scies qui nécessite un encombrement important de par leur mécanisme de transformation 20 rotation/translation. In the prior art, it is known to use saws that require a large amount of space because of their rotation / translation transformation mechanism.

Le but de la présente invention est de limiter l'encombrement par une configuration à plusieurs pièces intégrées les unes dans les autres pour obtenir une conformation faisant office de poignée de préhension pour une scie portative électrique pour une utilisation dans des espaces limités en encombrement. The object of the present invention is to limit the bulk by a multi-piece configuration integrated into each other to obtain a conformation acting as a handle for a portable electric saw for use in space limited space.

La diminution de l'encombrement peut se combiner en longueur comme en diamètre de poignée. The reduction in size can be combined in length and in handle diameter.
