Tool device with reversible drill bit/screw bit

Abstract

A tool holder comprising an elongated connector means having a first end and a second end, where the elongated connector means has a central longitudinal hole, of a cross-section corresponding to a cross-section of a mounting portion of the tool bit, at the first end, and a tool mount at the second end, and a first sleeve arranged to reciprocally slide over the connector means between a first end position and a second end position, the first sleeve having a third end facing the tool bit and a fourth end facing the hand tool. The connector means has a substantially cylindrical tubular first collar arranged on the connector means adjacent the first end, the first collar having an inner diameter which is cooperating with an outside diameter of the connector means, to allow the first collar to rotate on the connector means, the first collar further having a first recess to hold a first locking ball, and a second recess and a third recess arranged on an outer surface of the connector means adjacent the first end, the first locking ball being movable between the second recess and the third recess by rotation of the first collar, and the first locking ball being held in the first recess during rotation of the first collar, so that the first locking all is seatable into either of the second or third recesses, the first collar further having a fourth recess for holding a substantially cylindrical pin, which pin rotates together with the first collar, a part of the pin reaching out into a slot arranged in the connecting means, the slot and the pin being located so that, when the first locking ball is seated in the second recess, the pin is at one extreme of the slot, and when the first locking ball is seated in the third recess, the pin is located at the other extreme. Retention of the tool bit is enabled by offsetting the hex opening in the first collar to engage the slot in the bit.
