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.

A method of verifying a magnitude of a delivered output torque during a tightening operation of a threaded joint performed by a hand held power wrench including a housing, a motor, an output shaft, and a power transmission connecting the motor to the output shaft. The method includes: tightening the threaded joint; monitoring a magnitude of a direct torque acting along the power transmission during the tightening by at least one direct torque indicating sensor; monitoring a magnitude of a reaction torque transferred via the housing during the tightening by at least one reaction torque sensor; comparing the monitored magnitude of the direct torque with the monitored magnitude of the reaction torque; and determining, based on the comparison, whether the accuracy of the delivered output torque is acceptable.

A torque structure includes a first body, a second body, a first elastic member, a third body, and a limit unit. The second body is provided with a second receiving chamber, a first pivot portion, at least one first positioning portion and at least one second positioning portion. The first elastic member is received in the second receiving chamber. The third body is provided with a drive portion, a pivot seat, a second pivot portion, and a first limit portion. The limit unit is assembled with the second body and the third body and rotated between a disengaging position where the third body is unlocked from the second body and has a torque slip function relative to the second body, and a engaging position where the third body is locked by the second body and does not have a torque slip function.

A tool system includes an image capturing unit, a storage unit, a class identifier, and a spot determiner. The image capturing unit shoots a work spot of a target article and thereby generates captured image data. The storage unit stores a plurality of reference image data items with the plurality of reference image data items classified into multiple groups according to respective classes of the plurality of articles. The class identifier acquires identification information to identify the class of the target article. The spot determiner determines the work spot shot by the image capturing unit by comparing the captured image data with one of the plurality of reference image data items, which belongs to one of the multiple groups that is associated with the class of the target article identified by reference to the identification information.

A torque wrench including a head, a handle, a primary beam, a secondary beam, and a torque adjustment mechanism. The primary beam couples the head and the handle for co-rotation about the rotational axis and the primary beam includes a first end adjacent the head and a second end adjacent the handle. The secondary beam is coupled to the head for rotation with the head about the rotational axis and the secondary beam is movable relative to the primary beam and the handle. The torque adjustment mechanism adjusts a torque setting of the primary beam relative to the secondary beam. The torque adjustment mechanism includes a thumb adjustment wheel that a user rotates about a first axis to adjust the torque setting by moving the second end of the primary beam relative to the handle along a second axis offset from the first axis.

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 tool includes a first output from a gear system, the first output along a first axis and a second output from the gear system, the second output along a second axis. A first torque limiter is attached to the first output along the first axis and a second torque limiter is attached to the second output along the second axis. A first tool bit is attached to the first torque limiter along the first axis and a second tool bit attached to the second torque limiter along the second axis.

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.
