A rescue tool (10) comprises a drive system which is provided inside a housing and which is configured and suitable for actuating a linear displacement of an implement drive member. The drive system is connected for axial rotation to a rotation shaft of an energizable drive source (22), wherein the rotation shaft of the energizable drive source (22) is coupled for force transmission to an axially rotatable spindle (30). The spindle (30) is coupled rotatably to the housing (15) by means of an axial bearing assembly (25, 26) and the drive body (40) is coupled for force transmission to the spindle (30) and to the implement drive member. The drive body is configured and suitable for converting an axial rotation of the spindle (30) to a linear translation of its own.

A blade has a flat body with a first side, a second side, an aperture extending between the first side and the second side, and an outer peripheral edge. The aperture has a central axis defining an axis of rotation. A plurality of teeth is formed along a portion of the outer peripheral edge forming a cutting edge. Each of the teeth has a tip that is a radial outermost part of the flat body in a plane defined by the tip and the central axis of the aperture. The cutting edge has a first end and a second end. The distance between each tip of the teeth increases from the first end of the cutting edge to the second end thereof. The distance between each tip and the central axis increases from the first end of the cutting edge to the second end thereof.

A cable cutter and crimper is provided including an anvil having an anvil cutting edge. A blade is pivotally coupled to the anvil and includes a blade cutting edge. A clevis is coupled to the anvil and includes arms extending on opposite sides of an actuator screw. A pivot nut is threadably coupled to the actuator screw and pivotally coupled to the blade. Rotation of the actuator screw in a first rotational direction causes the pivot nut to translate along the actuator screw in a first translation direction, resulting in the blade cutting edge moving away from the anvil cutting edge. Rotation of the actuator screw in a second rotational direction causes the pivot nut to translate along the actuator screw in a second translation direction, resulting in the blade pivoting relative to the anvil to move the blade cutting edge toward the anvil cutting edge.

A hand-held tool (1) manually operable to compress or cut, the tool (1) being elongated bar-shaped or gun-shaped and including a casing (2) forming a grip portion, a motor (3) supported by the casing (2), a reduction and conversion mechanism (5) supported by the casing (2) and connected to the motor (3) and to an actuating member (6). The reduction and conversion mechanism (5) is configured to make the actuating member (6) translate along an actuating axis (7) in response to a rotational motion of the motor (3). A working head (8), connected to the casing (2), interacts with the actuating member (6) so that the working head (8) performs a compression or cutting movement in response to the translation of the actuating member (6). The reduction and conversion mechanism (5) has a conversion mechanism (9) with a planetary roller screw (10, 12, 14).

A cutting tool attachment for a power tool is freely rotatable about an end of the power tool. A fence provides a complementary flat surface area for the cutting tool attachment to rest against a surface of the material to be cut. The fence prevents free rotation of the cutting tool ttachment while in use. A handle allows a user to guide the attachment along the surface of the material, while also providing leverage to keep the attachment against the material surface close to the attachment, but at a safe position to reduce the chance of injury. A user can rotate the power tool relative to the cutting attachment to achieve a comfortable position or to help turn the attachment and power tool. The power tool is therefore positionable along a 360 arc of movement relative to the attachment while the attachment is positioned along the surface of a material.

An orthodontic wire bending device includes a providing part, a bending unit and a cutting part. The providing part is configured to provide a wire. The bending unit is disposed at a front side of the providing part, and includes a fixing part and a bending part. The fixing part is configured to fix the wire. The bending part is configured to bend the wire fixed by the fixing part. The cutting part is configured to cut the wire bent by the bending part. The bending part includes a bending module, and the bending module is rotated along a circumferential direction or moves along a direction to make contact with at least one side of the wire for bending the wire.

A portable rescue tool that is powered by an electric motor. The electric motor has a drive output shaft that transfers rotational power to an angle rotary gearbox. The angle rotary gearbox has an output shaft that is oriented about 90 degrees from the rotational axis of the motor output shaft and is geared so as to increase the torque and reduce the speed of the rotational power. The angle rotary gearbox provides a reduced speed, high torque output at an output shaft that is delivered by a single chain drive to a main rotary actuator where two actuator arms are controlled to move away from each other and toward each other in the operation of the rescue tool. The portable rescue tool is designed to be of a low weight and enhanced cooling properties as present rescue tools.

A hand tool with a mechanical linear drive mechanism coupled to a work implement. The drive mechanism includes a roller screw with a torque tube connected to a roller screw's nut body. The roller screw includes a fixed outer race, a rotating set of rollers axially aligned inside the outer race, a cylindrical nut body located inside the set of rollers, 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 to a multiple speed gearbox which includes a primary motor coupled to a carrier gear with three planet gears. Disposed around the planet gears is an outer ring gear. Coupled to the outer ring gear is a secondary motor which when activated causes the ring gear to rotate in the opposite direction of the planet gears.
