A tool head includes a first frame having a first arm and a second arm extending from a base to a distal end. The tool head may also include a first blade in the frame between the first arm and the second arm. The first blade is movable from the base toward the distal end. The tool head further includes a second frame hingedly coupled to the first arm. The second frame may include a second blade. The second frame is configured to rotate between a closed-frame position and an open-frame position. The tool head further includes a trip lever hingedly coupled to the first arm and configured to rotate between an open-lever position and a closed-lever position. The trip lever is in the open-lever position when the second frame is in the closed-frame position and the trip lever is in the closed-lever position when the second frame is in the open-frame position.

An example tool includes a hydraulic actuator cylinder; a piston slidably accommodated within the hydraulic actuator cylinder, where the piston includes a piston head and a piston rod extending from the piston head along a central axis direction of the hydraulic actuator cylinder, the piston head divides an inside of the hydraulic actuator cylinder into a first chamber and a second chamber, and the piston rod is disposed in the first chamber and configured to move one or more jaws of the tool; a pump configured to provide pressurized fluid; and a sequence valve configured to block the pressurized fluid from flowing into the second chamber of the hydraulic actuator cylinder until pressure of the pressurized fluid exceeds a threshold pressure value.

A hand tool with a mechanical linear drive mechanism coupled to a linear activated working implement. The drive mechanism includes a roller screw that includes a torque tube connected to a roller screw's nut body. The 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 multiple speed gear box which includes a primary motor coupled to a earner gear with three planet gears. Disposed around the planet gears is a ring gear. Coupled to the ring gear is a secondary motor which when activated causes the ring gear to rotate in the opposite direction of the planet gears. At least one sensor measures the rotation of an elastomeric ring and control activation of the secondary motor to change the operational speed of the tool.

A high-quality electrophotographic endless belt and a method capable of efficiently producing the belt are provided. A method for producing an electrophotographic endless belt comprising a base layer including a thermoplastic resin composition and an inner-surface layer, which includes: (1) forming an energy curable film having a glass transition temperature on an inner surface of a test tube-shaped preform including a thermoplastic resin and then subjecting the preform to blow molding to obtain a blow-molded bottle; (2) irradiating the blow-molded bottle with energy rays to cure the film to form an inner-surface layer; and (3) cutting out an endless belt from the blow-molded bottle having the inner-surface layer obtained in (2).

A portable motorised cutting tool has a motor housed in a tool body, a cutting member, a transmission linking the motor to the cutting member, and at least one guard for protecting the hand of the user, providing a passage for the hand around at least one of a control member of the tool, and a gripping handle of the tool. The tool has a cover capable of occupying a so-called “closed” position against the body of the tool, and a so-called “open” position separated from the body of the tool and giving access to a part of the tool protected by the cover in the closed position, the cover being linked to the body of the tool by the guard.

A hydrodynamic compression or cutting tool comprises a housing, an electric motor arranged in the housing and having a motor rotational axis, a gripping portion formed by the housing and extending around the motor and along the motor rotational axis, a hydraulic pump arranged inside the housing and which can be driven by the motor so as to move a actuating piston along a actuating axis, a transmission mechanism arranged inside the housing between the motor and the hydraulic pump, two jaws connected to the housing and to the actuating piston, and which can be moved between an open position and a closed position for carrying out the compression or cut, wherein the actuating axis and the motor rotational axis are reciprocally parallel and offset.
