Disclosed are aspects of exemplars of torque-limiting devices, methods and mechanisms. Exemplary methods may include placing an actuator in a tool containment interface of a handle, the interface being fluidly connected to an adjustment interface and adjustable via a fixation fastener; movably 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 an interface with the body catch and a force lever that forms an interface with the lever catch.

A torque wrench may include a head having a driving member configured to be operably coupled to a socket, a handle, a lever arm operably coupled to the head and the handle at respective opposing ends thereof, and a torque adjuster configured to enable a torque setting of the torque wrench to be adjusted. The torque adjuster may include a fixed member affixed to the lever arm and a movable member operably coupled to the fixed member. The handle may include a first end cap at a distal end thereof relative to the head and a second end cap at a proximal end thereof relative to the head, the second end cap being disposed proximate to the movable member.

A torque wrench with torque value indication includes a main body comprising an operation portion for driving a driven member to rotate about an axial center; a torque shaft passing through the main body and having one end connected with the operation portion and another end provided with a drive end exposed from the main body, the torque shaft being bent to deviate from the axis when a torque is generated; and a window disposed on the main body along the axis. The torque shaft gradually bends form the first end toward the second end in accordance with an increase of the torque, so as to correspondingly display a corresponding torque value with different length positions of the torque shaft along the window.

A jointing structure includes a jointing member and at least two abutting members. The at least two abutting members are disposed on the jointing member. The jointing member includes a surface and a plurality of side surfaces surrounding the surface, and the at least two abutting members are disposed on at least two of the side surfaces respectively.

A torsion tool is provided, including: a barrel; a first member disposed at one end of the barrel, including at least one first engaging portion; a second member, disposed in the barrel, including at least one second engaging portion releasably engaged with the at least one first engaging portion; an elastic mechanism, including a first fixation portion disposed in the barrel and elastic arms, the elastic arms being independently fixed to the first fixation portion and corresponding to each other, the second member being located between and configured to radially expand the elastic arms; wherein as the second member urges and radially expands the elastic arms, the at least one second engaging portion and the at least one first engaging portion are relatively slipable and disengageable.

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 golf club has a first shaft coupled to a club head, a second shaft configured to slidably engage a portion of the first shaft, a grip coupled to the second shaft, and an adjustable length shaft assembly received by the second shaft and configured to allow a portion of the first shaft to slide in relation to the second shaft in a first configuration, and to restrict a portion of the first shaft from sliding in relation to the second shaft in a second configuration. The grip is restricted from rotation about the first shaft or the second shaft as the first shaft slides in relation to the second shaft.

A switch structure of a hand tool contains: a body including an accommodation tube, a drive member, and a torque adjustment mechanism. The drive member is rotated in a first end of the accommodation tube, and the torque adjustment mechanism is arranged on a second end of the accommodation tube and abuts against the drive member so as to adjust a desired torque value. The drive member includes a positioning element extending from a second end of the drive member, and the positioning element has an outer diameter more than an outer diameter of the accommodation tube, the positioning element further has an engagement face formed on a first surface of the positioning element adjacent to the drive member. A control sleeve is fitted with the first end of the accommodation tube and is moved to a unlock position or a lock position by a user.

A torque structure includes a first body provided with a receiving recess, a second body pivotally connected with the first body, a first elastic member received in the second body, a retaining unit including a mounting seat provided with a first threaded portion and a plurality of first through holes, a first adjusting member provided with a head, a positioning seat provided with a plurality of second through holes, and a locking unit including a plurality of first locking members, a second locking member, a plurality of third locking members, a fourth locking member, a fastening member, and a second adjusting member. The fastening member is provided with a fitting portion connected with the first body. The fastening member is provided with a third threaded portion. The second adjusting member is provided with a fourth threaded portion screwed into the third threaded portion.

A torque screwdriver device is provided, including: a hosing, including a barrel and a cover coveringly connected with the barrel; an input shaft portion, rotatably assembled with the barrel; an output shaft portion, rotatably assembled with the barrel and including a socket mechanism; a torque clutch mechanism, including a first engaging portion disposed on the input shaft portion and a second engaging portion disposed on the output shaft portion, an elastic preload member biasing one of the first and second engaging portions, and a first bearing mechanism, the first bearing mechanism including a stop member abutted against the hosing, a support member abutted against the elastic preload member and at least one low friction member disposed between the stop member and the support member, at least one of the stop member and the support member being movable relative to the at least one low friction member.
