Socket

Handle for a hand tool and method for the manufacture thereof

A device for connecting a tool to a mechanical drive contains as the coupling element a spring washer coupling or clutch, which is made in one piece from metal and at least in the rotation direction has a limited resilience. Use is made thereof for preventing torque peaks in the case of a sudden deceleration of the tool, e.g. if a screw strikes a wood surface.

Device for connecting a tool to a drive

The invention proposes a handle for a screwdriver or a similar tool, which over a significant part of its length has a cross-section in the form of an approximately regular pentagon. The corner or angle sections are rounded with a radius of curvature, whose centre is in the longitudinal axis of the tool handle. The corner sections formed by the curved part of the cross-section have a different width over the handle length. The shape of the flattenings does not follow the shape of the handle contour.
