Abstract: A torque tool having a handle, a rotatable setting body for setting a torque, a display for a defined torque, which comprises a digit roller counter having at least two digit rollers. The digit roller counter is arranged in a hollow section of the handle with a viewing window through which the defined torque is visible, and has a passage through which a shaft section is guided. Between two digit rollers, a carrier disc arranged in a rotationally fixed manner in the handle is integrated. The carrier disc is rotatably assigned a control gear which has a driving toothing and a control toothing. One digit roller has an outer digit rim having a first rim section with a drive toothing and a second rim section with a control element. The setting body transmits a rotary movement of the setting body to the digit roller arranged on the setting body side.

Abstract: An impact powered torque wrench has a force-applying rod. The force-applying rod is connected to a transmission rod. A transmission shaft is disposed in the transmission rod. Two ends of the transmission shaft are connected to a head unit and a drive unit, respectively. A trip unit and an adjustment unit are provided between the force-applying rod and the transmission rod. An impact unit is provided between the transmission shaft and the drive unit. The drive unit drives the transmission shaft by means of intermittent impact, which increases the output torque and has a higher level of operational safety.

Abstract: A hand-held power tool, in particular a screwdriver, includes a housing, in which at least one drive unit for driving a tool holder is arranged, the tool holder being designed to hold an insertion tool. The hand-held power tool further includes a torque setting device for setting a specified torque at least within specified limits. The torque setting device has a screw thread region and a spring-loaded setting unit for setting the specified torque. The setting unit is operatively connected to the screw thread region. The torque setting device is assigned a compression spring which is coaxial to the screw thread region. The compression spring is arranged such that the screw thread region surrounds the compression spring at least partly with respect to the axial direction of the drive unit.

Abstract: Disclosed are aspects of exemplars of torque-limiting devices, methods and mechanisms exemplars methods may include placing an actuator in a tool containment interface of a handle; movable mounting a tool portion with an actuation catch and a work piece engaging region (WER) in the interface; applying sufficient force to the movable mounting to the handle may be via pins, guides and slots. Said catch may be one of a body catch and a lever catch; and, the actuator terminates on one of a ball shaped end that forms and interface with the body catch and a force lever that forms an interface with the lever catch.

Abstract: A control device is provided with a communication unit and a processing unit. The communication unit makes communication with a tool that is used for the work of fastening a fastener (for example, a screw) and with an image pickup unit for capturing an image of the work site where the work is being performed. The processing unit executes a determination process of determining whether or not the work is being performed normally on the basis of the fastening torque applied to the fastener by the tool and the image captured by the image pickup unit.

Abstract: A power tool may include an end effector configured to enable a fastener to be applied by the power tool via a fastening cycle, a power unit, a drive assembly configured to apply drive power to the end effector responsive to application of input power thereto, and a motor configured to supply the input power to the drive assembly selectively based on operation of a power control assembly that controls coupling of the motor to the power unit. The drive assembly includes a clutch configured to interrupt application of the drive power at a target torque. The power control assembly may be configured to adaptively change speed of the motor in response to the power tool reaching a predefined torque value that is less than the target torque during the fastening cycle.

Abstract: A torque wrench includes an elongated body, a head, and a cantilever beam. The body extends longitudinally from a proximal end to a distal end and includes a channel extending therethrough. The distal end includes an opening extending laterally therethrough along a central axis. The head is rotatably received within the opening at the distal end so that the head is rotatable about the axis. The head includes a gear cam defining teeth about a periphery thereof and an engaging portion sized, shaped, and configured to engage a corresponding engaging feature of a fixation device. The beam is housed within the channel such that a distal tip is received in a space between adjacent teeth. The beam bends when a torsional force applied to the head exceeds a predetermined limit so that the cam rotates about the axis and the distal tip slips from the space between the teeth into an adjacent space.
