A sleeve assembly for a shear wrench tool including an output sleeve configured to mate with a nut to facilitate winding of the nut onto a threaded bolt and having a plurality of circumferentially arranged locking features for interlocking with those of a transmission sleeve. A transmission sleeve for transferring torque between the output sleeve and at least one feature of a shear wrench tool transmission section. The transmission sleeve has a first set of circumferentially arranged locking features for interlocking with the locking features of the output sleeve and a second set of circumferentially arranged locking features for cooperating with a locking sleeve. A locking sleeve coupled to the output sleeve in a manner which permits the locking sleeve to rotate between first and second rotational positions relative to the output sleeve.

Sleeve assembly for shear wrench tool

A shear wrench tool including an electric motor having a motor output shaft, a transmission having a plurality of planetary gear stages and an output section having first and second output sleeves the first output sleeve being configured for mating with a nut and the second output sleeve being configured for mating with a tip of a bolt to be sheared, wherein the electric motor is configured to provide torque via the transmission to the output section for causing the first and second output sleeves to be rotated in opposite directions relative to each other in use, and wherein the electric motor, the transmission and the output section are arranged in an axial sequence one after the other such that the first and second output sleeves circumferentially extend coaxially around the same axis that the motor output shaft and the planetary gear stages rotate about.

Shear wrench tool

A shear wrench tool including an electric motor, an output section having first and second output sleeves and a transmission for transferring torque from the motor to the output section wherein in use the output sleeves are caused to be rotated in opposite directions relative to each another, the first output sleeve configured for mating with a nut and the second output sleeve configured for mating with a tip of a bolt to be sheared; the shear wrench tool further comprising an ejection mechanism having a first impact part which is both rotationally and axially movable and which has a first active surface, a second impact part which is rotationally restricted but axially movable and which has a second active surface, the ejection mechanism also having biasing means for urging the first active surface into engagement with the second active surface.

Syringe

A drill comprising: a body, the body comprising a housing formed internally with at least two chambers; a rear handle mounted on the body; a tool holder mounted on the front of the body; an electric motor mounted in a first chamber, the electric motor comprising an end cap attached to a motor housing; a transmission mechanism mounted in a second chamber which is in driving connection with the electric motor, the transmission mechanism being driven by the electric motor when the electric motor is activated to either impart impacts to and/or rotate a cutting tool when held by the tool holder. The end cap engages with the housing to form a separating wall which separates the first and second chambers.

Motor end cap

A hammer drill comprising: a body; a motor mounted within the body; a transmission housing mounted within the body, a transmission mechanism mounted within the transmission housing which is capable of rotatably driving and/or repetitively striking a cutting tool held by the hammer drill in response to rotation of an output shaft of the motor; wherein the transmission housing comprises a pair of housing portions adapted to engage each other to support the component parts of the transmission mechanism within the transmission housing; wherein the first housing portion is made from metal and the second housing portion is made from a plastic material, each of the components of the transmission mechanism being supported jointly be the first and second housing portions.

Hammer drill

A fastener supply assembly for a fastener driving tool includes an outlet passage arranged to expel fasteners from the assembly to a workpiece during use, a magazine comprising a plurality of supply channels arranged to hold fasteners and supply them to the outlet passage, and a channel selector. The channel select has an opening and is arranged to selectively connect, via its opening, the outlet passage with each respective supply channel of the magazine, by movement of the channel selector relative to both the magazine and a longitudinal axis of the outlet passage. The movement of the channel selector may comprise rotation about the longitudinal axis of the outlet passage.

Fastener supply assembly

A fastener assembly includes an elongate fastener, and a support collar mounted on the elongate fastener. The support collar is shaped such that it has profiles on opposite sides of the elongate fastener that are asymmetric with respect to each other. The asymmetry may be an asymmetry in the number, shape, position, or size of recesses on two opposite sides of the elongate fastener. A plurality of fastener assemblies may be provided as a fastener strip, in which each support collar is joined to one or two adjacent support collars in a strip.

Fastener assembly

A hammer drill, in particular a chipper comprises: a body having at least one support handle; an electric motor mounted within the body; an electric switch, capable of being switched on and off by a trigger button connected to it, to activate or deactivate respectively the electric motor, wherein the trigger button is moveable between two positions, a first position where the electric switch is off and a second position where the electric switch is on; a locking arm moveably mounted on the electric switch which, when the trigger button is located in its second position, is moveable between two positions, a first position where it is disengaged from the trigger button and a second position where it engages with the trigger button and holds the trigger button in its second position. When the locking arm is in its second position it causes the hammer to remain switch on even if the operator removes their fingers from the trigger button.

Hammer drill with mode lock on

A fastener driving tool arranged to drive fasteners into a workpiece includes at least one electric motor having a central stator and an external rotor arranged to rotate around the stator. The rotor may be in the form of a flywheel. The tool includes an energy transfer member such as a driver arranged to transfer kinetic energy from the rotor to a fastener held in the tool, thereby to drive the fastener from the tool into a workpiece. The electric motor may be a brushless motor. The tool may include two such motors, arranged such that both of their rotors propel the driver simultaneously.

Fastener driving tool having energy transfer members

A resilient stop assembly for an impact tool includes first and second resiliently deformable parts, and a substantially rigid part situated between the deformable parts. Each of the first and second resiliently deformable parts and the substantially rigid part comprises: first and second opposite impact surfaces, at least one peripheral surface joining the impact surfaces, and an aperture extending entirely through the part between exit openings in the impact surfaces. The first impact surface of the second resiliently deformable part is separated from the second impact surface of the first resiliently deformable part by contact of those first and second impact surfaces with the substantially rigid part.
