Device for attaching awls in their exercise books.
The subject matter of the present invention is a device for securely attaching awls in their booklets, which at the same time allows the pins to be easily exchanged while they can be rotated. The subject of the invention is shown in Fig. 1 in view. Fig. 2 shows a diagrammatic representation of a clamping piece.
In the usual booklet a made of wood, an insert piece b made of metal is used, which has a slightly conical bore; To fix the awl b, two clamping pieces c of semicircular cross-section, provided with a bead at the top and corresponding to the bore of the insert b, are used, each of which has a groove corresponding to the thickness of the awl used on their cut side.
The awl is inserted into this groove formed by the two flutes and then the
EMI1.1
As a result of the friction occurring due to the wedge effect, the awl is held securely and easily exchangeable in the handle.
