Abstract (en)
The tool (10) has an adjusting unit movable with respect to a spring (14) and intended to connect a handle (12) to a coil of the spring for modulating number of active coils. The adjusting unit has a rod (24) movably mounted within the spring by being screwed and threaded with pitch adapted to that of coils of the spring. The spring is placed in a rest position and is not subjected to any constraints when the tool is not utilized. An independent claim is also included for a device for tensioning a spring of a torque tool.
