Abstract

Eine motorgetriebene Handwerkzeugmaschine für Trennarbeiten, insbesondere Handkreissäge, hat ein Gehäuse (11) und eine Grundplatte (14) und ist mit deren Unterseite (15) auf ein Werkstück aufsetzbar, wobei die Grundplatte (14) in Bezug auf das Sägeblatt (13) um eine unterhalb der Grundplatte (14) und parallel zur Schnittvisierlinie verlaufende Schwenkachse (16) mittels am Gehäuse (11) einerseits und an der Grundplatte (14) andererseits angreifender Schwenk-Führungsmittel (19, 20) schwenkbar und in jeder Schwenklage feststellbar ist. Die Schwenk-Führungsmittel (19, 20) bilden eine kulissenartige Führung entlang einer kreisbogenförmigen Führungsbahn und sind miteinander verbunden. Sie weisen einen vorzugsweise integrierten Bajonettverschluß auf, über den die Teile der Schwenk-Führungsmittel (19, 20) miteinander verbindbar sind.

Figure 00000001
A motor-driven hand tool for cutting work, in particular a hand-held circular saw, has a housing (11) and a base plate (14) and can be placed on a workpiece with its underside (15), the base plate (14) being one in relation to the saw blade (13) below the base plate (14) and parallel to the cutting line of sight pivot axis (16) by means of the housing (11) on the one hand and on the base plate (14) on the other hand pivoting guide means (19, 20) can be pivoted and can be locked in any pivot position. The swivel guide means (19, 20) form a link-like guide along an arcuate guide path and are connected to one another. They have a preferably integrated bayonet lock, via which the parts of the swivel guide means (19, 20) can be connected to one another.
