A power tool is provided comprising: a power source; a power tool housing comprising a first mechanical coupling connectable with a second reciprocal mechanical coupling on a power tool accessory; and a first electrical coupling in electrical connection with the power source and mounted on the first mechanical coupling. The first electrical coupling is electrically connectable with a second reciprocal electrical coupling on the power tool accessory.

Power tool, power tool accessory and coupling arrangement therefor

Electric hammer

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 power tool includes a rotatable support arrangement for supporting at least one cutting disc. An upper shroud member and a lower shroud member cooperate to define a volume in which the at least one cutting disc can be supported. The rotatable support arrangement can be coupled to the upper shroud member such that movement of the upper shroud member towards the lower shroud member causes the cutting disc to protrude through an opening in the lower shroud member. A biasing member urges the upper shroud member and the lower shroud member away from each other. A limiting mechanism limits the range of movement of the upper shroud member relative to the lower shroud member under action of the biasing member. The limiting mechanism can be disengaged by opening the upper shroud member via at least one hinge coupling.

Dust extractor

An adaptor for a dust extractor is provided including a housing having a top portion and a bottom portion, a first aperture formed in the top portion of the housing, a second aperture formed in the bottom portion of the housing, and an adaptor catch having a first end and a second end. The adaptor catch is vertically slidable within the housing between a first catch position, where the first end projects through the first aperture, and a second catch position, where the first end is located flush with or inside of the housing. The second end of the adaptor catch is accessible through the second aperture. A first biasing mechanism biases the adaptor catch towards the second catch position.

A switch mechanism includes a support structure and an electric switch having an activator moveable between a first position where the electric switch is ON and a second position where the electric switch is OFF. A cam is connected to a first actuator, moveably mounted on the support structure, so that movement of the first actuator results in movement of the cam. A bar is connected to a second actuator, moveably mounted on the support structure, so that movement of the second actuator results in movement of the bar. The cam engages the activator so that movement of the cam by movement of the first actuator results in the activator moving between its two positions. The bar engages the activator so that movement of the bar by movement of the second actuator results in the activator moving between its two positions.
