Description
Die Erfindung geht aus von einer Handwerkzeugmaschine nach dem Oberbegriff des Anspruchs 1.The invention relates to a hand tool according to the preamble of claim 1.
Es sind Handwerkzeugmaschinen, insbesondere Handbohrmaschinen und Bohrhämmer mit Gehäusen in Topfbauweise mit einem am Ende des zylindrischen Gehäuses angeordneten Verschlußdeckel bekannt. Dieser Deckel ist jedoch nur umständlich unter Zuhilfenahme von gesonderten Werkzeugen zu öffnen, wobei er nicht oder nur sehr bedingt als Servicedeckel zum Wechseln der Kohlbürsten geeignet ist. Außerdem ist der bekannte Deckel nicht gegen Verlieren am Gehäuse sicherbar.There are hand tool machines, in particular hand drills and rotary hammers with casings in Topfbauweise with a arranged at the end of the cylindrical housing cap known. However, this cover is only awkward to open with the help of separate tools, and it is not or only very suitable as a service cover for changing the cabbage brushes. In addition, the known lid is not secured against losing the case.
Die Handwerkzeugmaschine nach dem Anspruch 1 hat den Vorteil, daß der stirnseitige Gehäusedeckel gegen verlieren gesichert ist.The hand tool according to claim 1 has the advantage that the frontal housing cover is secured against losing.

- Figur 7 einen ausschnittsweisen Längsschnitt des BohrhammersFigure 7 is a partial longitudinal section of the hammer drill
Figur 1 zeigt eine räumliche Darstellung einer als Bohrhammer ausgestalteten Handwerkzeugmaschine 10 in der Ansicht von links vorn. Die Handwerkzeugmaschine hat ein Gehäuse 12, das aus einer linken und rechten längsgeteilten Gehäuseschale 121, 122 mit einem als Spatengriff ausgestalteten Handgriff 14, der eine Schalttaste 16 enthält, aus der nach unten ein E-Kabel 18 zur Energieversorung des nichtdargestellten, im Inneren eines zum Gehäuse 12 gehörenden Motor-Gehäuse 20 angeordneten Motors austritt. Das Motor-Gehäuse 20 ist einstückig mit den Gehäuseschalen 121, 122 in Motorgehäuseschalen 201, 202 geteilt, die gegenüber einer Längsachse 27 der Handwerkzeugmaschine 10 rechtwinklig abgewinkelt angeordnet sind. Die Längsachse 27 ist durch einen Maschinenhals 22, ein Spannfutter 24 und ein als Bohrer ausgestaltetes Einsatzwerkzeug 26 definiert.FIG. 1 shows a three-dimensional view of a hand-held
Ebenfalls rechtwinklig nach unten tritt ein Zusatzhandgriff 28 von der Längsachse 27 weg, der am Maschinenhals 22 mittels eines Spannbandes 30 abnehmbar gehaltert ist.Also at right angles down an
