A setting method for an electronic torque tool is disclosed. The electronic torque tool includes a tool body that stores at least one operation set. The operation set includes at least one adjustable operation parameter of the electronic torque tool. The setting method can be used to adjust the operation parameter in the operation set and includes a setting step and a storing step. The setting step includes entering the operation set and adjusting the operation parameter therein. The storing step includes storing the adjusted operation parameter in the operation set directly after an operator quits the operation set or turns off the electronic torque tool during the setting step. The setting method allows the operation parameter in the operation set to be easily and rapidly set or adjusted, thereby making the electronic torque tool easy to use and operate.

A torque structure includes a first body, a second body, a first elastic member, a retaining unit, an adjusting unit, a mobile unit, and a display unit. The second body has a first guide slot. The first body is rotated relative to the second body to drive the adjusting unit to rotate and move relative to the retaining unit to adjust the torque value. The mobile unit is received. in the second body and aligns with the first guide slot. The mobile unit is mounted between the first elastic member and the adjusting unit. The first body drives the adjusting unit which moves the mobile unit which adjusts the compression extent of the first elastic member to adjust the torque value. The display unit display unit detects a position of the mobile unit and indicates a torque value.

An electronic torque wrench with a battery receptacle adapted to receive either a unitary battery pack or a battery tray containing separate batteries inside. The battery tray can receive conventional batteries such as AA, AAA, C, D or 9-volt sized batteries, and the battery tray and unitary battery can be constructed of a similar geometry to fit within the battery receptacle. The battery tray and unitary pack can include an outwardly-extending protrusion that is received within a groove of the battery receptacle. In this manner, only the specially-designed battery tray and pack are capable of coupling with the receptacle.

A torque wrench (100, 400) may include a body (410), a force detector (420) operably coupled to the body and configured to detect a bending force applied to the body, and a user interface (140) operably coupled to the body and the force detector. The user interface may be configured to include a setting mode in which a variable feature of the torque wrench is adjustable. The user interface may be further configured to, when in the setting mode, adjust the variable feature based on the bending force applied to the body and detected by the force detector.

A battery holder structure is disposed on an electric wrench which includes a battery unit, and the battery holder structure includes a back cover assembly. The back cover assembly is assembled on an end of the electric wrench, and the back cover assembly includes a cover, a supporting member, a first elastic member and a second elastic member. The cover has an accommodating space. The supporting member is disposed in the accommodating space. The first elastic member is assembled on an end of the supporting member, an end of the first elastic member contacts with the cover, and another end of the first elastic member contacts with the supporting member. The second elastic member is assembled on another end of the supporting member, an end of the second elastic member contacts with the supporting member, and another end of the second elastic member contacts with the battery unit.

A torque wrench for controlled tightening of threaded couplings, including a substantially tubular body, a grip positioned at a first end of said tubular body, a tightening head positioned at a second end of said tubular body, a tightening torque setting mechanism positioned inside said tubular body, an indicating device for indicating when the tightening torque set has been reached, a recognition device for recognising an element to be tightened and/or elements that are positioned at the element to be tightened, said recognition device being connected to said tubular body, preferably at said second end, and a control unit connected to said recognition device and designed to associate with the element recognised by said recognition device a tightening torque design value to be set.

A clamping tool is provided comprising a body, containing control circuits and electronic processing circuitry and having, at one end, a handle for gripping by an operator making the clamping, and on the other end, an arm. The arm comprises, at its free end, a seat that can be alternatively pluggable to a plurality of inserts suitable for engaging the tool with a corresponding type and/or dimension of a mechanical member on which the tool is configured to operate to perform a clamping operation. Sensor means are provided on the arm for detecting tightening conditions exerted on the mechanical member. Furthermore, a microprocessor electronic card is provided on the are for receiving analogic signals from the sensor means, converting the signals into digital format, and handling transfer of the signals in digital format to the electronic processing circuitry.

A rotating power tool is provided. The rotating power tool may include a bevel gear set having a bevel gear and a conductive spiral disposed on the bevel gear. The conductive spiral may be configured to, in response to the bevel gear deforming due to a torque being applied to the bevel gear, change a resistance of the conductive spiral. The rotating power tool may further include an antenna electrically connected to the conductive spiral. The antenna may be configured to emit an output signal at a frequency that is based on the resistance value of the conductive spiral. The frequency of the output signal may be indicative of an amount of torque being applied to the bevel gear.

A wrench device includes a data receiving component configured to receive, from a transceiver associated with a piece of equipment, information related to a fastener included in the piece of equipment, and a torque value corresponding to the fastener. The wrench device further includes an image sensor configured to capture an image of the fastener, a processor, and a memory communicatively coupled to the processor. The memory stores processor-executable instructions, which, on execution, cause the processor to receive the image of the fastener from the image sensor, receive the information related to the fastener from the data receiving component, identify the fastener by correlating the received image with the information related to the fastener, extract the torque value corresponding to the fastener based on the information upon identification of the fastener, and adjust a torque of the fastener based on the extracted torque value.

An electronic torque wrench (10) comprises a body with an axial extension along a longitudinal axis (11), a front end provided with a coupling (14) intended to engage the wrench on a joint to be tightened by manual rotation around a rotation axis (15) which is transverse to the longitudinal axis (11), and a handle (13) along the body for operating the wrench. A sensor (16) is intended to detect a torque applied with the wrench to the coupling (14) and comprises two flex sensor elements (16a and 16b) which are arranged spaced apart along the longitudinal axis (11). An electronic control circuit (17) is connected to the sensor (16) for receiving signals from it and is intended to implement a method which comprises the steps: calculating, depending on flexing values detected by the two sensor elements (16a and 16b), the point P along the longitudinal axis (11) which is used for applying the manual force of rotation of the wrench about the rotation axis (15); comparing the position of the point P with admissible predefined positions along the longitudinal axis (11); and emitting an error signal if the position of the point P does not correspond to these admissible positions.
