The power tool comprises a first power tool portion having a rotatable collar and a first locking member arranged to be actuated by the rotatable collar and a second power tool portion having a second locking member. The rotatable collar is rotatable about an axis for actuating the first locking member to removably engage the first locking member with the second locking member, thereby releasably locking the first power tool portion with the second power tool portion along the axis.

A supply device designed as a separately positionable peripheral unit for supplying a processing device with elements, wherein a connection point is designed with a hollow transfer line that can be connected to the supply device such that the elements can be transferred in the hollow transfer line from the connection point to the processing device. The elements are transferred by means of a gas flow. The supply device has a gas flow generation device that transfers the elements from the connection point due to the gas flow provided by the gas flow generation device. The supply device is provided in an installation space, and the gas flow generation device takes in air from the environment of the supply device in the installation space of the supply device in order to provide the gas flow.

Provided is a cylinder connection assembly comprising a ventilation connection sleeve sleeved on a piston shaft of the cylinder, the ventilation connection sleeve fixedly provided in a cylinder barrel of the cylinder and separates an inner cavity of the cylinder barrel to form front and rear air chambers, a first ventilation hole communicating with the front air chamber and a second ventilation hole communicating with the rear air chamber are provided on the ventilation connection sleeve, so that when the compressed gas is filled into the front air chamber through the first ventilation hole, or the compressed gas is filled into the rear air chamber through the second ventilation hole, the piston assembly in the cylinder barrel can move axially. Through the ventilation connection sleeve provided in the cylinder barrel, the compressed gas can directly enter the front air chamber or the rear air chamber through the ventilation hole thereon.

Disclosed is a magazine attachment for a device for driving fastening elements into a support, comprising an attachment part which has a connecting region for connecting the magazine attachment to the device, and a pressing part which has a contact region for placing the magazine attachment against the support. The attachment part and the pressing part are held together in such a way as to be movable along a movement path which is delimited by a normal position and a pressing position. An outer contour of the pressing part has three contact points which define two half-lines forming a right angle. In the normal position and in the pressing position, the attachment part and the pressing part are entirely located within a volume formed by the right angle and a straight line that intersects the two half-lines at the vertex of the right angle.

A fastener installation tool and related method are provided for installing fasteners in boards. The tool can include a feed mechanism that automatically and sequentially feeds collated fasteners to a nose assembly. The nose assembly can include a guide having an alignment projection extending downwardly from the guide, and configured to engage a board corner and/or side surface, so as to align an angled bore through which fasteners are guided with the board corner and or side surface. The nose assembly can include a magnetic element located adjacent a path on which the collated fasteners are advanced. The magnetic element can exert a magnetic force on an individual fastener, aligning it for precise entry into the angled bore. The nose assembly can include a guide pocket to positively constrain a fastener as it rotates to ensure a desired advancement trajectory. A related method of installation is provided.

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.

An installation tool and related methods are provided. The tool can pull a strip of collated fasteners along a collated fastener path to a guide, where individual fasteners are sequentially separated from the strip and advanced into a workpiece. The tool can include a tension feeder located downstream of the guide. The tension feeder is configured to apply tension to the strip between the guide and a leading end of the strip. The tool can include a driveshaft configured to attach to a conventional drive tool chuck or a drive tool having hexagonal type drive components. The guide can be one piece and replaceable, with a guide body and a guide head. A strip slot can be defined in the same to align a fastener head with a backstop and facilitate entry of a fastener shank in a feed slot. Related methods of use are provided.

A fastener staging and placement system comprising a staging member capable of temporarily attaching to structures and storing a plurality of ring type fasteners, and a placement member with a means for gripping and removing one or more fasteners to and from the staging member. The staging member comprises a removable and substantially vertically oriented dowel, configured to present a series of ordered sets of fasteners to the placement member, and an attachment means that may be removably attached to various structures. The placement member comprises two or more gripping arms that are configured to flex and exert pressure on at least one fastener thereby securing an ordered set of fasteners.
