摘要： A fastener driving tool includes a shaft with a working region disposed at a first end of the shaft and configured to drive a fastener, a shank portion disposed proximate a second end of the shaft and configured to couple the shaft to a power tool, and a reduced diameter torsion zone disposed between the shank portion and the working region, the torsion zone extending from a first shoulder closer to the working region to a second shoulder closer to the shank portion. A length (L) and a radius (c) of the torsion zone have been optimized so that approximately half of breakages occur in the working region and approximately half of breakages occur in the torsion zone.

摘要： A hand-held machine tool is disclosed. The tool has an electric motor and an output shaft which can be driven by the electric motor about a working axis. The output shaft has an intake space which is open on the output side for receiving a machine tool and which has two elongated holes cutting into the intake space in the radial direction. Blocking elements lie in the elongated holes and protrude into the intake space and are movable between an end on the output side of the elongated hole and an end on the drive side of the elongated hole. The blocking elements abut on a radial stop in the radial direction and are forced into the intake space in an engaging manner. The stop overlaps in a locked position with the ends on the output side of the elongated holes and can be moved in the withdrawal direction against a spring force of a spring for releasing a radial movement of the blocking elements from the engagement with the intake space. A second spring includes a support ring, two bows protruding from the support ring in the withdrawal direction and bent around the intake space in the form of a segment of a circle, and a pin engaging radially from each bow in the withdrawal direction in front of the blocking element into the elongated hole.

摘要： A bit holder assembly for a rotary hand or powered tool, includes a body having a hex shank at its rearward end and a retraction collar slidably disposed on the body. The body has a coaxial hex socket formed therein to allow a tool bit to be inserted thereinto. A coil spring biases the retraction collar forwardly and biases a retaining clip toward the bottom of an angular slot formed in the body. The bit is removed by sliding the retraction collar rearwardly, to compress the coil spring and allow the retaining clip to retract back up the slot. A ring magnet is disposed at the forward end of the retraction collar to magnetize a fastener to retain the fastener to the bit.

摘要： A coupling device of jigs includes a foundation, a tube, a plurality of balls, and a piston base. The foundation has a chamber, in which a part of the tube is inserted. The tube has a plurality of through holes for housing the balls. The piston base is received in the chamber, and fitted to the tube. An inner surface of the piston base has a circular groove and an abutment surface. The piston base can be moved along an axial direction of the tube between a first position and a second position. When at the first position, a part of each ball is inside the circular groove; when at the second position, an area where the abutment surface abuts against each ball is not merely a single point. Whereby, the force applied on the abutment surface is dispersed, and therefore the processing accuracy of workpieces is ensured.

摘要： Several preferred embodiments are disclosed for a tool-less blade clamping apparatus for a reciprocating tool of the type which has a reciprocating plunger which has a tool attachment receiving slot for receiving a tool attachment of the type that has a shank portion. The clamping apparatus has an unclamped position and a clamped position. In the unclamped position, a tool attachment can be easily inserted and when it is in its clamped position, the tool attachment is securely retained. The preferred embodiments have at least one spring biasing the apparatus toward the clamped position, a releasable retaining mechanism for holding the apparatus in its unclamped position after being placed in that position. When the blade shank portion is inserted into the slot a predetermined distance, the shoulders of the shank portion release the retaining mechanism to move it to its clamped position. When a blade is to be removed, the clamping apparatus needs only to be moved to its unclamped position by manually rotating the outer sleeve or collar, and the blade is normally ejected from the mechanism by contact with the blade shoulders as it reaches its unclamped position.
