    摘要: The invention provides a power tool including a tool body and a handle mounted on the tool body at an upper vibration isolation joint and a lower pivot joint. The lower joint permits pivotal movement of the handle relative to the tool body while giving an operator lateral stability and torsional control over the tool. The upper joint serves as a primary vibration isolation joint and includes a spring which is precompressed to a minor fractional portion of its unloaded length and which is positioned between the tool body and the handle to bias the tool body and the handle apart. The spring is compressible from its precompressed state responsive to operator applied pressure, and when operator applied pressure on the handle is maintained within predetermined levels the spring is operable to reduce transmission of vibration from the tool body to the handle during tool operation.
