摘要:
A handle assembly for a power tool is disclosed. The handle assembly comprises a base (6) adapted to be mounted to a body of a power tool, and a handle (4) having first and second mounting portions (16) pivotably mounted to respective ends of the base. An elongate torsion spring (18) has a first part (20) mounted to the base and a respective second part (22) mounted to each mounting portion such that pivoting of the handle relative to the base member causes twisting of the torsion member to resiliently oppose pivoting of the handle relative to the base portion.

A mounting assembly for moveably mounting a handle of a power tool to a housing of the power tool is disclosed. The mounting assembly has a metal bar (324) mounted to a housing (290) of the power tool and a vibration damper (332) mounted to a handle (294) of the power tool and slidably mounted to the metal bar. The vibration damper includes a vibration damping member (344) for damping vibrations tending to cause the vibration damper to pivot relative to the metal bar about an axis substantially parallel to the longitudinal axis of the metal bar.
