Abstract
A device (12) for detachably fixating a portable drilling machine to guide holes in a template includes a sleeve (20) having a substantially cylindrical portion to be inserted into a guide hole, and an expansion member (26) with a lever (34) extending radially from an axial portion thereof. The expansion member (26) is pivotally mounted in a recess (36) in the sleeve about a pivot center (38). The sleeve has two axial, circumferentially spaced contact sections (24), whereas the expansion member (26) has a third axial contact section (32) for engaging the wall surface of the guide hole. The expansion member (26) is biased by a spring (44), via the lever, towards a locking position in which all three contact sections (24, 32) may engage the wall surface of the guide hole so as to fixate the drilling machine to the template.
