OVERRIDE ARRANGEMENT AND ACTUATING HANDLE FOR A SHIFTING MECHANISM IN PORTABLE TOOLS

摘要

The invention is directed to an override arrangement and handle for a shifting mechanism in portable tools. The portable tool includes a housing and a drive motor mounted in the housing. A case extends from the housing and a transmission is operatively connected to the motor and mounted in the case. A shifting mechanism engages the transmission for adjusting the same between at least two modes of operation. The shifting mechanism includes a shaft penetrating the case and rotatable between two positions corresponding to respective ones of the modes of operation. The improvement includes a handle attached to the shaft that is contoured so as to abut against the case when the handle is rotated past one of the two positions thereby preventing the operator of the tool from overriding the one position.
