A tool includes a tool body, a tool head, and an actuator. The tool head is rotatable with respect to the tool body. The actuator can rotate together with the tool head. The actuator is movable between a first configuration and a second configuration. In the first configuration, the actuator and the tool head cannot rotate with respect to the tool body. In the second configuration, the actuator and the tool head can rotate with respect to the tool body.

A working head (1) for a compression or cutting tool (100) comprises a connecting portion (3) for a removable connection of the working head (1) with an actuation part (2) of the tool (100), two jaws (4) movable between an open position and a closed position to perform the compression or cutting, and a local storage (6) configured for storing one or more cumulative data representative of a stress history of the jaws (4), wherein the local storage (6) is fixed to the working head (1).

Portable, hand-held hydraulic tools having a modular power unit within a handle assembly and a working head assembly mated to the handle assembly. The working head assembly can have a pair of movable jaws or a movable jaw and a fixed jaw. The jaws can be configured to perform different operating operations, such as crimping operations and cutting operations.

There is provided electric pruning shears capable of arbitrarily adjusting an opening/closing width of a blade so as to improve user's satisfaction. Electric pruning shears 1 that cut an object sandwiched between a movable blade 4 and a fixed blade 5 is provided with a control board 109 that executes: a setting changing operation of operating, when a maximum open position adjusting portion 80 receives a change input, a motor 6 to move the movable blade 4 at the maximum opening angle with an opening/closing width before change to the maximum opening angle with an opening/closing width after change; and a movable blade opening/closing operation of operating, when an operation portion 60 is operated, the motor 6 to open/close the movable blade 4 between the maximum opening angle and the maximum closing angle with the opening/closing width after change.

A hand tool with a mechanical linear drive mechanism coupled to a linear activated working implement. The drive mechanism includes a geared planetary roller screw that includes a torque tube connected to a roller screw's nut body. The planetary roller screw includes a fixed outer race, a rotating set of grooved rollers axially aligned inside the outer race, a cylindrical nut body located inside the set of grooved roller, a plurality of inner rollers axially aligned and inside the nut body, a threaded shaft axially aligned and inside the inner rollers, and a torque tube axially aligned inside the inner rollers. The torque tube is connected at one end to a gear box which is coupled to an electric motor. When the electric motor is activated, the torque tube is rotated which causes a threaded shaft in the tool to move axially. A working implement is coupled to the distal end of the threaded shaft.
