An interactive software application on a mobile computing device is used to configure an electronic torque wrench via a wireless connection. The software application obtains torque specifications for a vehicle from a remote database. When the torque specification require that work pieces be torqued in an ordered sequence, the software application guides the technician through the sequence, but accommodates changes when the technician departs from the sequence.

An electronic torque wrench with double display screens includes a main body having a shank. A front end of the shank has a working head. The shank is defined with a central vertical face in the longitudinal direction. The electronic torque wrench further includes a display unit having two display screens. The two display screens are respectively disposed on two sides of the central vertical face. The two display screens are disposed by an inclination and directed upward and outward, whereby a user can easily observe the torque value displayed on the display screens.

An electric wrench, which is operated in an electric mode and a manual mode, includes a wrench body having a head portion having a ratchet device and a handle portion; a motor disposed in the handle portion; a current sensor connected with the motor for detecting an operation current value of the motor; a controller connected with the current sensor, the controller having a setting unit and a comparing unit, the setting unit setting a threshold current value, the comparing unit comparing the operation current value and the threshold current value; a switch activating and deactivating an operation of the motor; and a warning device connected with the controller. In the electric mode, when the operation current value is greater than the threshold current value, the warning device is triggered for user to switch to the manual mode.

A socket having functions of torque sensing, angle sensing, and signal transmitting is provided. The socket includes a socket body, a circuit board module, a deformation strain sensing unit, an output/input module, a power supply module, and a protection device. Wherein, the socket body has variable structures to accommodate the circuit board module, the deformation strain sensing unit, the power supply module and the output/input module, and to protect the accommodated elements by the protection device. Accordingly, the socket has the functions of torque sensing, angle sensing, and signal transmitting.

An electronic tool for copying a plurality of settings from a first mechanical tool to a second mechanical tool comprises: a smart device having a processor, and having a non-transitory memory storing program instructions executable on the processor. The program instructions are configured, when executed on the processor, to: read the plurality of settings from the first mechanical tool; and write the plurality of settings to the second mechanical tool.

A method and a system for assembling a screw connection for a predefined operating load. The system includes a detector configured to detect values of at least one influence factor on the screw connection, a calculator configured to determine, based on the operating load, a required pretensioning force of the screw connection, and, based on the determined pretensioning force, to determine an expression of at least one assembly parameter, and an assembler configured to assemble the screw connection in accordance with the determined expression of the assembly parameter.

To provide a manual tool excellent in workability and operability and capable of precise tightening torque management, a manual tool includes a grip including a bit holding part that detachably holds a bit, and a torque sensor that is of a magnetostrictive type, and includes a detecting pan that is penetrated by the bit held by the bit holding part and surrounds an outer periphery of the bit, the torque sensor is capable of contactlessly detecting a torque acting on the bit, and is detachably provided to the grip. The torque sensor can be configured to be formed so as to be mountable to the grip with the bit mounted to the bit holding part of the grip.

A vibrating wrench includes a housing, a driving head, a handle and a vibrating structure. The housing includes a hollow space. The driving head is disposed at one end of the housing. The handle is disposed at the other end of the housing and includes an inner wall and a containing space. The containing space is communicated with the hollow space. The vibrating structure is disposed in the containing space of the handle and includes a vibrating motor and a medium element. The medium element is fully connected or partially connected to an outer surface of the vibrating motor. The inner wall of the handle is fully connected or partially connected to the medium element.

An apparatus for tensioning a fastener while measuring displacement of the fastener relative to a female threaded member may include a driver extension having an interior channel aligned along the extension's central cylindrical axis, open to a socket driver at an output end of the driver. The apparatus may further include a measurement probe in the interior channel, coupled to a measurement indicator on an exterior of the extension by a coupling that moves the measurement indicator in proportion to movement of the measurement probe and a measurement gauge coupled to an exterior of the driver extension that gauges displacement of the measurement indicator. A method for using the apparatus includes driving a female threaded member along a threaded rod by the driver extension while holding the measurement probe against an end of a bolt, screw, or other threaded fastener of which the threaded rod forms a part and while reading the measurement gauge.

A torque-sensing and transmitting device is provided. The device includes a transmission body, two vibration-damping members, two inner casings, two outer casings, a first circuit board module, and a battery module. The two inner casings are disposed on a shaft of the transmission body, and a vibration-damping member is disposed between the inner casing and the shaft. The first circuit board module is disposed in one of the two inner casings, and the first circuit board module is covered by a vibration-damping layer. The battery module is disposed on the other inner casing, and the battery module is covered by a vibration-damping layer. With the configuration of the vibration-damping member and the vibration-damping layer, this device solves the problem of the first circuit board module and the battery module being damaged due to vibration.
