A synchronously linkable hand tool includes a base, a rotation mechanism, a first driven mechanism and a second driven mechanism. The rotation mechanism is rotatably connected to the base and includes a driving gear. The first driven mechanism is disposed on the base and includes a first driven gear and a first locking/unlocking member connected to and rotated by the first driven gear. The second driven mechanism is disposed on the base and includes a second driven gear and a second locking/unlocking member connected to and rotated by the second driven gear. The first driven gear and the second driven gear are rotated by the driving gear to synchronously rotate the first locking/unlocking member and the second locking/unlocking member. Therefore, the force is uniform during locking or unlocking to avoid damage to the workpiece.

A hand tool for fastening a fastener, such as a screw. The hand tool comprises a handle and a rotatable fastening head connected to a first end of the handle, and engaged with a manually driven actuator. The hand tool further comprises a fixed fastening head connected to a second end of the handle, which is configured to apply a configurable fastening torque to the fastener The fixed fastening head is selectively pivotable with respect to the handle about an axis parallel to the center axis of the fixed fastening head.

An apparatus for adjusting a height adjustable leg for supporting a cabinet, appliance or structure is described. The apparatus includes a foot of a height adjustable leg and a tool comprising a driving member and a torque input for applying torque to the driving member. The foot includes a rotatable foot part with a driven member and a base part to support the rotatable foot part on a floor or supporting surface. The tool and the foot are complementarily adapted to releasably maintain engagement between the driving member and the driven member to allow the driving member to drive the driven member to rotate the rotatable foot part about a longitudinal axis of the leg for height adjustment of the leg.

A cabinet leg is provided including a body securable to an underside of a cabinet and a shaft engageable with the body such that rotation of the shaft moves the shaft toward or away from the body. A foot is secured to a lower end of the shaft including a first portion attached to the shaft and a second portion rotatable relative to the first portion. A plurality of openings are provided around the periphery of the foot for receiving a first end of a tool such that teeth on the tool engage with teeth on the first portion. Rotation of the tool causes rotation of the first portion relative to the second portion, thereby rotating the shaft and adjusting the height of the cabinet leg.

A clamping device for a screw connection, provided with a threaded bolt and a threaded nut, has a support tube surrounding the threaded nut, a cylinder housing arranged in an extension of the support tube, a piston movable in the cylinder housing by hydraulic pressure, an exchange bushing axially entrainable by the piston and provided with an internal thread for screwing the exchange bushing to the threaded bolt, and a follower element arranged inside the support tube and frictionally or with form fit connectable to the threaded nut. A drive element is rotatably mounted outside the support tube and provided with a tool surface for applying a hand tool. A gear arrangement is located between the drive element and the follower element. The gear arrangement has a clutch operating as a function of torque to prevent reliably excessive forces when the threaded nut is re-tightened and/or screwed on.

A tensioning apparatus is provided that is arranged to simultaneously tension a plurality of jackbolts of a multi jackbolt tensioner (MJT). The tensioning apparatus has a housing that is arranged for receiving a drive gear from a drive unit. The tensioning apparatus includes one or more planetary gears that are retained within the housing and which mesh with the drive gear in use. A ring gear encircles the one or more planetary gears and meshes with them. A plurality of spindle gears is retained in the housing. Each of the spindle gears has a spindle for coupling to a respective one of the jackbolts. The spindle gears are located around the ring gear and mesh with teeth on an outside of the ring gear. In use the drive gear rotates the one or more planetary gears to thereby rotate the spindle gears via the ring gear to thereby tension the jackbolts. The tensioning apparatus may be made compact by overlapping gear disks of the spindle gears and acts as a torque multiplier between the planetary gears and the spindle gears.

The 90 Degrees utilizes dual ratio constant mesh gears which provides suitable use for ratchets in hard to access spaces, and particularly well suited for automotive use. The mesh gears are configured to be used either with manual or pneumatic tools. A female socket element recedes into the housing having gears therein and a male socket element meshes with the female socket element and is shaped to accommodate a female socket element at 90 degrees or the adapter element of a drive ratchet. You can use an elongated drive shaft to accommodate distance. Positioned within the housing of the adapter body are gears secured to mesh within the housing of the adapter. Rotation of the female socket element by a drive ratchet in one direction will rotate the male socket element in the opposite direction without any change in direction is governed by the ratchet use.
