Abstract

This invention relates to a movement transfer mechanism for a portable power tool, such as a cutting device. The mechanism includes a movement transfer block, a shaft configured to be linked to a driving means, wherein the shaft includes a head configured to engage with the movement transfer block, a linking arm to a working element, which may be a cutting blade, the linking arm configured to engage with the movement transfer block, the mechanism characterised in that the movement transfer block includes a first aperture substantially in line with the head of the drive shaft, and a second aperture substantially inline with the linking arm of the working element. Rotation of the drive shaft causes reciprocal movement of the linking arm, and therefore movement of the working element with which the linking arm engages.
