Abstract
An apparatus for receiving a functional unit for a power tool, wherein the receiving apparatus can be fastened to the power tool by way of a fastening mechanism. A second aspect of the invention relates to a method for fastening a receiving apparatus of this kind to a power tool. In the fastening mechanism, a rotatable insert part can be inserted into an opening of the receiving apparatus and can be moved from an unfastened to a fastened state by this rotational movement. In the fastened state, a hook of the power tool engages with a raised portion of the insert part.
Claims16
An apparatus for receiving a functional unit for a power tool, the apparatus fastenable to the power tool and comprising:
- a cutout for forming a dovetail connection;
- a fastening mechanism including an opening in the apparatus and
- a rotatable insert part insertable into the opening, wherein the opening is formed by a bore on a side averted from the power tool;
- and
- a slot for receiving a hook on the power tool, the slot being on a side facing the power tool, and, in a fastened state, the hook is in engagement with a raised portion of the insert part for fastening the apparatus to the power tool.
A method for fastening a receiving apparatus for a functional unit to a power tool, the method comprising the following steps:
- providing a receiving apparatus in an unfastened state, wherein the unfastened state of the receiving apparatus is defined by a position of an insert part in the receiving apparatus;
- inserting a pin of the power tool into a cutout of the receiving apparatus;
- inserting a hook of the power tool into a slot of the receiving apparatus;
- rotating the insert part within the receiving apparatus, so that the receiving apparatus is moved from an unfastened to a fastened state and a connection between the power tool and the receiving apparatus is obtained.
