A magazine strip that is fed to a drive-in device via a chute extending at an angle to the drive-in direction is disclosed. A deflector consisting of tongues is provided at the outlet end of the magazine guide, which deflector deflects the magazine strip away from the straight-ahead direction and directs the magazine strip quasi upward such that the magazine strip either extends perpendicularly to the drive-in direction or even back in parallel with the insertion chute, depending on the extent of the deflection. In order that the magazine strip follows this motion, the magazine strip has hinges, the axes of which extend transversely to the longitudinal direction of the magazine strip, and thus, at an angle to the screws located in the retainers of the magazine strip.

A magazine type screwing device and a screw supplementary device are provided. The screwing device includes a screwdriver bit with a protrusion part, a storing portion, and a screw stopping portion. The storing portion includes a tubular structure and a slide rail, which are connected with each other. The screwdriver bit is installed in the tubular structure. The screws are disposed within the slide rail. After the screwdriver bit is moved within the tubular structure in a first direction and then the screwdriver bit is moved within the tubular structure in a second direction, one of the screws is detached from the screw stopping portion and introduced into the tubular structure. The screw supplementary device includes a screw transferring portion and a screw feeding portion. The screw transferring portion includes a first conveying track, a sensing element over the first conveying track, a gear, and a first motor.

A chuck is composed of a body (2), gripping jaws (10) provided on the body (2), and feed structures (20) disposed in containing chambers (4) of the body (2), and the feed structure (20) is composed of a cylindrical body (21) having a male screw portion (22) formed thereon, a first receiving body (27) fitted in one end side of the cylindrical body (21), a second receiving body (35) fitted in the other end side of the cylindrical body (21), an eccentric shaft (40) consisting of an base shaft portion (41) and an eccentric portion (42), an external gear (45) having a through hole (46) formed to extend from front to rear through an central portion thereof and having the eccentric portion (42) of the eccentric shaft (40) inserted in the through hole (46), an internal gear (50) having a teeth portion partially meshing with a part of a teeth portion of the external gear (45), a screw body (55) composed of a screw member (56) and a flange member (60), and a coupling body (65) disposed between the first receiving body (27) and the external gear (45).

A positioning assembly for a driving system, the assembly having a first jaw and a second jaw, the first jaw fixed to a driver guide tube, the second jaw fixed to the first jaw to allow one end of the first jaw to rotate away from the second jaw about a connection point, each jaw having an interior channel. The interior channel of the first jaw has an arcuate cross-section. The interior channel of the second jaw is formed from a plurality of walls including an arcuate upper wall and a sub-channel having cross-section formed by a base surface and two side walls, each side wall angled with respect to the base surface. The apparatus also includes a locking member configured to engage the second jaw when the second jaw is rotated away from the first jaw and retain the second jaw in a rotated position.

Various embodiments described herein provide a fastener system having straight walled driving surfaces that provides a reliable stick fit feature, while also improving stability of engagement between the system components. A feature of the new system is to allow stick fit engagement of existing standard straight walled drivers in the new system.

A magazine is configured to be removably coupled to a power tool housing of a power tool. The magazine has a housing configured to be rotatably attachable to the power tool housing. An advancing mechanism is received in the magazine housing, and is configured to advance a strip of collated fasteners into position to be driven by the power tool. An indexing ring has a plurality of recesses and is configured to be non-rotatably attached to the power tool housing. A detent is biased to removably engage one of the plurality of recesses, and is configured to be non-rotatably attached to the magazine housing. The detent removably engages the recesses to allow for indexed tool-free rotation of the magazine housing relative to the power tool housing.
