Abstract:
1. A safety torque intensifying tool, comprising a housing; a drive; torque intensifying means for intensifying a torque of said drive, accommodated in said housing and operative for providing at least two modes of operation including a first mode in which the torque intensifying tool operates with a high speed and a low torque and a second mode in which the torque intensifying tool operates with a low speed and a high torque; a grip to be held by a tool operator; an additional element acting as a handle for better gripping in said first mode in which the torque intensifying tool operates with the high speed and the low torque and also as a reaction arm to abut against a stationary object to stop said housing from turning in said second mode when the torque intensifying tool operates with the low speed and the high torque; and switching means for switching the torque intensifying tool between said first and second modes and configured so that when the tool operator does not act on said switching means the torque intensifying tool is in said second mode of operation with the low speed and the high torque and when said switching means is acted on by the tool operator while said additional element acts as a handle, the torque intensifying tool is switched to said first mode of operation with the high speed and the low torque, until the tool operator stops acting on said switching means and the torque intensifying tool is switched itself back to said second mode of operation.
