POWER WRENCH WITH REACTION BAR CONTROLLING MEANS |
摘要 |
A power wrench includes a housing divided into two parts which are rotatable relative to each other: a first part including a handle and a transverse section lodging a rotation motor, and a second part including a reduction gearing, an output shaft and a rigidly attached and laterally extending reaction bar. A swivel connection is provided between the housing parts and includes an angle sensor arranged to generate signals in response to relative angular movements between the housing parts, and a power control unit communicates with the angle sensor and is arranged to at least substantially reduce the motor power as a pre-set maximum angular movement between. the housing parts is exceeded as the motor is started.
