Abstract: A magnetic cleaning device includes a handle unit, a main unit, and a deforming mechanism. The main unit includes a housing and a magnetic member. The deforming mechanism is connected between the handle unit and the main unit. The housing defines an accommodating space extending along an axis. The magnetic member is disposed in the accommodating space, and is movable along the axis between an attraction position, where the magnetic member is adjacent to an end of the housing, and a non-attraction position, where the magnetic member is away from the end of the housing. The main unit is movable relative to the handle unit via operation of the deforming mechanism.

Abstract: A speed-selectable hand tool includes a handle, a cage member fixed to the handle, a shaft member extending into the cage member, a sleeve member sleeved on the shaft member and extending into the cage member, a plurality of transmission members each meshing with the shaft member and the sleeve member, a plurality of pawls mounted to the cage, a knob surrounding the pawls, and an outer casing mounted with the transmission members. The speed-selectable hand tool is operable to serve as a non-ratcheting hand tool or a ratcheting hand tool by rotating the knob relative to the cage member to actuate the pawls. The rotational speed of the shaft member relative to the handle is selectable through operation of the outer casing.

Abstract: An electronic torque wrench includes a handle unit, a turning unit, a sensor unit, an operating unit, and a processor unit electrically connected to the sensor unit and the operating unit. The turning unit includes a wrench head member, first and second positioners, and a sleeve. The wrench head member has a head portion, a strain-measurement portion, and a shaft portion extending from the strain-measurement portion and rotatably received in the sleeve. The first and second positioners are connected to opposite ends of the shaft portion and exposed from the sleeve. The first positioner retains the wrench head member at a predetermined angular position relative to the sleeve and the handle unit.

Abstract: A reversible tool assembly includes a main member, a driven unit for driving the main member to rotate about an axis, first and second movable members coupled respectively to the main member and movable in the direction of the axis, and a reversible tool unit mounted pivotally between the first and second movable members. The reversible tool unit is movable together with the first and second movable members between an extended position, where pivot action thereof is permitted, and a retracted position, where pivot action thereof is not permitted.

Abstract: A tool storage device is adapted for retaining a hand tool thereon, and includes a seat engaging component and a storage unit. The seat engaging component includes a web wall, and top and bottom walls cooperating with the web wall to define a receiving space. Each of the top and bottom walls has a distal edge. The distal edges cooperatively define an opening in spatial communication with the receiving space. The storage unit includes a slidable seat that has a connecting portion extending into the receiving space through the opening, a positioning plate connected to an outer end of the connecting portion and mounted with a positioning seat, and upper and lower engaging components disposed in the receiving space, each extending from an inner end of the connecting portion and abutting resiliently against the web wall of the seat engaging component.

Abstract: A magnetic tool storage rack includes a main rack body having a positioning wall, and a magnetic assembly. The magnetic assembly includes a fixing unit and a magnet unit. The fixing unit is installed on the positioning wall and is made from a non-magnetic material. The fixing unit defines a receiving space, and has an opening formed in one side opposite to the positioning wall and in spatial communication with the receiving space. The magnet unit includes at least two magnet components, each of which is disposed in the receiving space, has a wall contacting part that extends through the opening in the fixing unit, and is movable linearly in the receiving space in directions toward and away from the positioning wall of the main rack body to result in a variable length of the wall contacting part that extends through the opening.

Abstract: An electronic torque wrench includes a tubular housing having a receiving space, a working unit having an abutment portion extending into the receiving space, a strain sensor provided in the working unit, and a trip unit disposed in the receiving space and including a cylinder having a chamber containing hydraulic fluid, a trip element disposed movably between the abutment portion and the cylinder and having a seat portion, and a control element connected to the cylinder for pressurizing or depressurizing the hydraulic fluid so as to permit the abutment portion to be seated on or to move away from a center of the seat portion. A central processor is connected electrically to the strain sensor and the control element, and controls the control element to depressurize the hydraulic fluid when an applied torque measured by the strain sensor is larger than a preset reference torque value.

Abstract: An electronic torque wrench includes a tubular housing having a surrounding wall confining a receiving space, a working unit having a shank portion extending axially into the receiving space and pivoted to the surrounding wall at a pivot point, a strain sensor provided in the working unit, a trip unit having at least one driven element disposed in the shank portion, and a central processor connected electrically to the strain sensor and the trip unit. The driven element is movable to a tripping position, in which the driven element is not pressed tightly against the surrounding wall so that the working unit is permitted to pivot relative to the tubular housing. The central processor controls and moves the driven element to the tripping position when an applied torque measured by the strain sensor is larger than a preset reference torque value.
