Abstract

A suspension unit for a power tool comprises a pair of telescopically engaged members and a spring unit acting between the members to draw one member within the other. The member is provided with a support bracket whereby it can be hung from a support in use and the member is adapted to support the power tool. Means in the form of a lateral peg mounted upon a movable guide block to which the member is secured, and a slot through which the peg extends, acts to prevent relative rotation of the members. In this way any reaction torque developed on the power tool will be transmitted to and resisted by the support.
