There is provided a tightening operation analysis apparatus configured to analyze a tightening operation performed by a worker using a tightening tool. The tightening tool includes a head configured to be able to engage with a tightened member, and a main body configured to pivotally engage with the head and turn when a tightening torque for tightening the tightened member reaches a preset torque value. The tightening operation analysis apparatus includes a motion information acquisition unit configured to acquire motion information indicating a turning motion of the main body, from the tightening tool, and an analysis unit configured to output a result of analysis of a load condition of the tightened member during the tightening operation, based on the motion information acquired by the motion information acquisition unit.

The tightening tool includes: a main body configured to be able to be held by a worker and including a turn detector; a head having an approximately rod shape and provided in the main body, which can engage with a tightened member; a head pin configured to pivotally support the head in the main body to turn the main body with respect to the head; and a spring configured to restrict the main body from turning with respect to the head by a compressive force in a longitudinal direction of the head. When a tightening torque reaches a preset torque value, the turn detector is released from restriction by the spring to turn around the head pin in a first direction and then turn in a second direction, and therefore detects turns of the main body with respect to the head in the first direction and the second direction.

A multi-functional TPMS sensor fastener torque tool includes a torque driver and a user interface which allows a user to identify the TPMS sensor to be serviced, obtain a recommended fastener torque from a reference torque value database, measure the torque applied to the sensor fastener and alert the user when the reference torque has been reached or exceeded. In one example, the reference TPMS fastener torque values are stored in a memory device in the torque tool which are accessible through a plurality of graphic user interface menus on a display device.

A zero distance tool for turning a fastener is disclosed. The tool may have a driver configured to receive a torsional input. The tool may also have an adapter rotatably coupled to the driver. The adapter may be configured to engage with a fastener. The tool may have a housing configured to enclose the driver and the adapter.

A system and method performed by the system comprising obtaining a work parameter measured by a smart tool connected to an electronic device; and displaying information associated with the work parameter on a display of the electronic device. A system and method perform by the system comprises measuring a work parameter associated with a smart tool operating on a workpiece; and sending the work parameter to an electronic device connected to the smart tool to enable the electronic device to display information associated with the work parameter on a display of the electronic device.

A torque wrench includes a mechanical structure and an electronic structure. The mechanical structure includes a tubular body, a flexible rod, an abutment member, an elastic member, a trip mechanism, an adjustment mechanism and a mechanical scale indication mounted in the tubular body for indicating the set torque of the wrench. The electronic structure includes at least one torque sensor and a display unit. When correcting the torque value of the mechanical structure, a force is applied to the wrench and the torque sensor detects the trip torque value of the wrench. The torque value of the mechanical structure is adjusted to match the torque value detected by the torque sensor so as to eliminate the error of the torque value of the mechanical structure.

A connection structure is connected between a wrench head of a torque wrench and a socket, and the connection structure contains: a body, a casing, and two positioning members. The body includes a coupling section, a driving section, an extension defined between the coupling section and the driving section, and two bolts oppositely inserted into the body from an outer wall of the coupling section. The casing includes a first part, a second part, and two accommodation grooves respectively defined on two inner walls of the first part and the second part and located adjacent to the coupling section. Each of the two positioning members is housed in each of the two accommodation grooves, wherein each positioning member includes multiple toothed projections arranged on an inner wall thereof and abutting against each of the two bolts.

A torque wrench for use in driving fasteners is provided. The wrench includes an electronics unit disposed within a housing engaged with the body of the wrench that is capable of sensing and measuring the torque applied to a fastener by the wrench and providing an output of the level of torque to the user. The data sensed by the electronics unit can be utilized to provide feedback to the user regarding the operation of the wrench, and to monitor the overall operation of the wrench for calibration purposes, among other functions. During use, the wrench can provide the user with visual, audible and tactile feedback regarding the operation of the device relative to stored maximum torque values stored in the electronics unit. The housing for the electronics unit can be formed to be a single use component of the tool or can be designed for multiple uses with a configuration that can be engaged with cradles forming the body of the wrench having various different configurations.

An electric tool includes a motor, a driving controller, an output shaft, a transmission mechanism, and a seating detector. The driving controller controls the motor. The output shaft is to be coupled to a tip tool for use to fasten a fastening member. The seating detector detects seating of the fastening member. The driving controller controls the motor to make a number of revolutions of the motor at a point in time of the seating equal to a predetermined number of revolutions associated with a torque setting. The driving controller changes a value of a motive power to be supplied to the motor into a predetermined value or less in response to detection of the seating by the seating detector.

An electronic torque wrench with sensing structure includes a tubular body, a working head and at least one sensing element. The working head includes a head section and a connection section secured in the front end of the tubular body. The head section is positioned at the front end of the tubular body. The sensing element is disposed on an outer circumference of the tubular body. Accordingly, the length of the connection section of the working head is greatly shortened and the internal structure of the tubular body is simplified to lower the material cost and manufacturing cost. In addition, the weight of the torque wrench is reduced and the sensing precision of the sensing element is enhanced, whereby a user can more easily hold the torque wrench and more smoothly use the torque wrench to enhance the whole benefit of the torque wrench.
