Abstract
A tool handle for a file used for sharpening of saw chains consists of two interconnected tubular parts, rotatably connected in relation to each other, and each having an outer shell member surrounding a central tube having its axis offset in relation to the rotary axis. By relative rotary movement of the tubular parts, the tubes lock an inserted file by eccentric action. The tool handle is further provided with apertures forming a whistle and with angled filing guides.
Claims9
A tool handle comprising first and second handle parts having a common longitudinal axis, a joint connecting said parts for at least limited relative rotation of the parts about said axis, means defining a longitudinally extending through bore in one of the handle parts with an opening at one end of said one handle part remote from the joint for insertion of an elongate tool into the handle, the through bore having an axis which is offset from said common longitudinal axis, means defining a further longitudinal bore in the other of said parts for receiving an end portion of the tool inserted into said through bore, the further bore also having an axis which is offset from said common longitudinal axis, the handle parts having a relative rotational position wherein the respective axes of said through bore and further bore are substantially coaxially aligned for receipt of the tool and wherein relative rotation of the parts from said position about the common longitudinal axis provides relative eccentric displacement of the respective axes of the through bore and further bore effective for clamping the tool in the handle.
