Security holding jaws on a tool ring for a nail machine

摘要

The present invention relates to aspects of securing holding jaws in nail machines, including a method, a machine, a tool ring and a holding jaw for such purposes. The novel aspects of the invention include that holding jaws are secured to a tool ring in a manner where a number of immovably secured passive fittings are used as well as a number of active fittings. It is hereby ensured that holding jaws may be e.g. replaced without loosening many other holding jaws, and that the holding jaws may be placed very precisely and in a manner, which is repeatable. It is also ensured that the holding jaws may be effectively and easily secured. The passive fittings will each provide at least one fix point from where one or more holding jaws may be lined up, in a manner where the interdependency between the secured holding jaws is reduced, whereby a larger degree of precision is obtained, also when a high number of holding jaws are involved, and also when the distance between the jaws are identical along the entire circumference of the tool ring.
