A power tool includes a casing, a cutting unit, a transmission device, and a toggle switch. The casing includes a support portion. The cutting unit is used for cutting a target object and moving between a first position and a second position relative to the support portion. The toggle switch includes at least a third position and a fourth position. When the toggle switch is at the third position, the cutting unit performs a first motion: the cutting unit moves from the second position to the first position. When the toggle switch is at the fourth position, the cutting unit performs a second motion: the cutting unit moves from the first position to the second position. A speed at which the cutting unit performs the second motion is greater than a speed at which the cutting unit performs the first motion.

The present disclosure provides hand-held, battery-powered tools for performing operations such as crimping and cutting, and having a remote monitoring and control systems. A frame of the tool supports a working head, a battery, a motor connected to the battery, a controller and a camera.

A shearing apparatus includes a housing, a die within the housing, and a workpiece seat plate attached to the housing by a standoff. The die has a cutout which is positionable to align with a passageway through the housing. The workpiece seat plate is spaced from the housing by the standoff, and has a cutout which at least partially aligns with the passageway in the housing and the cutout in the die.

A device and method for operating a motor-actuated working device is provided. A certain working operation requires a rise in an applied force to a certain working force. The device enables a rise in the force to a general working force that exceeds the certain working force and an apparatus is provided for monitoring the device value. For the certain working operation, an evaluation is performed to detect the characteristic change and that the attainment of the characteristic change is used as a signal for ending the certain working operation after the certain working force has been attained but before the general working force has been attained.

A powered threaded rod cutter includes first and second cutting dies, an electric motor, a planetary transmission positioned downstream of the motor, a drivetrain for converting a rotational output of the transmission to a pivoting movement of the first cutting die, and a clutch mechanism for redirecting torque from the motor away from a drivetrain and the first cutting die in response to the first cutting die seizing during a rod-cutting operation. The clutch mechanism includes a ring gear in the planetary transmission, and a spring that rotationally affixes the ring gear below a predetermined threshold of reaction torque through the drivetrain and permits rotation of the ring gear above the threshold.

A ring removal apparatus configured to remove a ring from a finger utilizing a first technique or a second technique. The first technique employs cutting the ring while the second technique utilizes elements to distort the shape of the ring achieve removal. The ring removal apparatus includes a cutting assembly wherein the cutting assembly has a void centrally located therein and an opening thereto. The void has a first blade member and a second blade member on opposing sides thereof. The first blade member includes a ring protrusion member operably secured thereto and in axial alignment with the first blade member. The second blade member is movable in a forwards-backwards motion and is moved via a hydraulic assembly. The hydraulic assembly includes a conventional hydraulic cylinder that is operated via an operational lever so as to provide the movement of the second blade member.

A hydraulic actuation device includes a tool, an actuation part having a pressure oil supply mechanism configured to send pressure oil from an oil chamber to the tool and return return oil from the tool to the oil chamber, an operation handle for adjusting oil passages for the pressure oil and the return oil in the pressure oil supply mechanism and configured to be able to be moved from an initial position, and biasing means configured to bias the operation handle toward the initial position when no external force is applied to the operation handle. When the operation handle moves from the initial position, the tool is actuated by the actuation part. When the operation handle is returned to the initial position by the biasing means, operation of the tool by the actuation part is stopped.

An apparatus, system, and method for shearing cables, such as those used in concrete support structures, is presented. In one embodiment, an apparatus is presented that can include a casing, a handle, a cutting nose, a torque conversion mechanism, and a cable support. The cable support can be configured to removably couple to a cable, such as to secure the cable within a cable groove of the apparatus. In another embodiment, a system for cable shearing is presented, wherein the system comprises a shearing apparatus and torque-generation apparatus. In another embodiment, a method of clipping cables, such as within a pocket, is presented.

A pliers-type cutting tool having two tool legs which cross at a joint pin and are pivotable about an axis of rotation in a pivot plane with respect to one another. The tool legs form gripping portions on one side of the joint pin and a pliers mouth on the other side. Cutting of the pliers mouth pass into a position one over the other, at least radially on the outside, for the first time in a closing region. The cutting edges have in the position one over the other only in the closing region a particular free length on this central plane, and that over the free length a greatest opening width is present along an intermediate length on the central plane, and that the greatest opening width makes up a third or more of the total length of the cutting edges.
