Abstract:
1. An adjustment mechanism for a power tool, the mechanism comprising: a support made of a resilient material and including a first support portion and a second support portion; a first rotary member attached to the first support portion and having a first axis of rotation and adapted to be rotated by an adjustment dial gripped by a user of the power tool; and a second rotary member attached to the second support portion and having a second axis of rotation, not coincident with said first axis of rotation, and adapted to rotate as a result of rotation of said first rotary member to transfer torque from said first rotary member to an input of a control circuit of the power tool to adjust a setting of the tool, wherein the first support portion is moveable independently with respect to the second support portion in a direction along the length of the first and second rotary member so that, in the event of an impact to the adjustment dial if the tool is dropped, the first rotary member flexes relative to said second rotary member to reduce transmission of impacts from the adjustment dial to the input of a control circuit.
