Abstract: A centering vice is provided, including: a base, a clamp assembly and an adjusting assembly. The base includes a sliding groove extending in a first direction and a first abutting portion. The clamp assembly includes a first jaw portion and a second jaw portion. The adjusting assembly includes a threaded rod, a positioning member and two adjusting members. The threaded rod includes a first threaded segment, a second threaded segment and a positioning portion. The positioning member is immovably connected to the positioning portion and disposed between the two adjusting members, and the two adjusting members respectively have a second abutting portion abutted against the first abutting portion. The two adjusting members are movable relative to the base in a second direction lateral to the first direction to urge the positioning member to move in the first direction.

Abstract: A torque wrench includes a wrench body, a deformable rod, a torque adjustment mechanism, a switch and an alarm. The wrench body includes a working section and a gripping section. Two ends of the deformable rod are fixed to the working section and the gripping section respectively, and a middle section is formed in-between. The torque adjustment mechanism is installed in the gripping section and includes a knob and an abutting member. The knob adjusts the abutting member to be proximate to or away from the middle section. The switch is disposed between the middle section and the torque adjustment mechanism. The alarm is electrically connected to the switch, and the middle section is in a bending deformation toward the abutting member, when load of the working section is greater than a set torque, to touch the switch and trigger the alarm to generate a warning signal.

Abstract: An industrial sweeper operates by rolling along a floor to be cleaned, pushed or pulled, including: a brush with a horizontal axis depending on the use position of the industrial sweeper on a horizontal floor, a collecting pan for collecting dirt swept by the brush, the collecting pan mounted and able to pivot between a closed and working position and a wide open position allowing the pan to be emptied, a suction turbine downstream of the collecting pan suctioning dust into the collecting pan when in closed position, two wheels for resting on the floor, an air filter, an unclogging mechanism for unclogging the air filter. The air filter is fixed on the collecting pan and the unclogging mechanism includes an end stop to block travel of the collecting pan in its wide open position, the end stop causing a shock at the end of the collecting pan opening movement.

Abstract: A tool includes a first accessory, a second accessory, a first attachment portion configured to allow the first accessory to be detachably attached thereto, a second attachment portion configured to allow the second accessory to be detachably attached thereto, a first intermediate member configured to be displaced from a first non-attachment position to a first attachment position by the attachment of the first accessory to the first attachment portion, a second intermediate member configured to be displaced from a second non-attachment position to a second attachment position by the attachment of the second accessory to the second attachment portion, and a single sensor configured to detect a specific state in which the first intermediate member is located at the first attachment position and the second intermediate member is located at the second attachment position.
