A wrench extender includes an extension member and a retaining member. The extension member has a wrench supporting base with a supporting face and first and second sides adjacent to the supporting face and respectively disposed at two opposite sides of the supporting face. The wrench supporting base is provided with a first holding portion arranged on the supporting face and adjacent to the first side, and a second holding portion arranged on the supporting face and adjacent to the second side. The retaining member is arranged on the wrench supporting base to retain a wrench hold by the wrench supporting base.

The pivoting and extending interchangeable hand tool device disclosed herein may comprise a tool head and a torque arm that pivot relative to one another, a secondary torque arm for extending length and increasing appliable torque, and a “T”-handle for additional support. The pivoting and extending interchangeable hand tool device may further comprise a plurality of tool heads that may be interchanged within the secondary torque arm, and may be provided commercially in a multiple-tool set. The device is designed to overcome the shortcomings in the prior art, which specifically include the ability to work in tight spaces while reducing the loss of torque when pivoting a torque arm, the loss of strength inherent in an extendable torque arm, and the bulkiness of a “T”-handle.

The combination of a driver and fastener that allows a user to insert and remove the fastener by applying larger than normal torque loads to it includes: (a) a fastener with a proximal end handle and a distal end head configured to provide a standard indentation and an additional recess that provides additional surface area that allows larger torque loads to be applied to the fastener, (b) a main driver with a shaft having a central bore, a handle at its proximal end and a head at its distal end configured to allow it to be temporarily inserted into the fastener's head, and (c) an awl driver having an awl shaft with an awl handle affixed to its distal end and its proximal end including a tip configured to allow it to pass through the main driver's bore and be brought into contact with the fastener's head where it is used to cut into the fastener cannula so as to temporarily adhere the awl driver to the fastener.

A ratchet wrench system and kit enable users thereof to enhance grip and mechanical advantage in applying torque to either (a) rotate rotary fasteners or (b) prevent rotary fastener rotation. The ratchet wrench system and kit include at least one ratchet wrench assembly and at least one ratchet interface. The ratchet wrench assembly has a ratchet head and a lever arm. The ratchet head has a male side and a female side. The female side includes both deep and shallow sections. Long and short ratchet interface elements both include a male interface end and a female interface end. The male and female interface ends are respectively matable with the female and male sides of the ratchet wrench assembly. The long and short ratchet interfaces are interchangeably matable with the ratchet wrench assembly for enabling a secondary wrench to grip and enhance mechanical advantage via the ratchet wrench assembly.

A tap holder includes a body extending along an axis and having a front end portion defining a front opening and an externally threaded portion. A gripping assembly includes a spring having first and second legs, a first jaw mounted to the first leg, and a second jaw mounted to the second leg. Each jaw has a tapered outer wall and an inner wall with the inner walls of the jaws facing each other. A sleeve has an internally threaded bore threadably received on the externally threaded portion of the body, and an inner tapered surface configured to abut the tapered outer walls of the first and second jaws. As the sleeve is rotated relative to the body, a distance between the first and second gripping surfaces may be adjusted for gripping a tap between the inner walls of the first and second jaws. Each of the inner walls includes first and second gripping surfaces, the first gripping surfaces defining a first width therebetween for gripping taps having a first range of head sizes, and the second gripping surfaces defining a larger second width therebetween for gripping taps having a second, different range of head sizes.

A fluid-operated, reciprocating piston-style torque wrench and a method of operating the same. The wrench may have pump controls coupled to the torque wrench. The pump controls may be connected to a handle assembly that is coupled to the torque wrench. The handle assembly may include sensors to require two hand operation of the pump controls.

A screwdriver includes a shank having a driving end and a connection end which is fixed to a handle. The handle has a core portion which is mounted to the connection end of the shank by way of injection molding. Multiple first portions and multiple second portions are alternatively attached to the outside of the core portion. The first portions are made of material that is softer than that of the second portions so as to provide comfortable grasp to the user's hand.

A quick release structure of a T-shaped ratchet wrench, and the ratchet wrench being comprised of a transverse force applying handle and a longitudinal acting handle, and a ratchet steering and a driving mechanism being installed at a junction of the two handles and provided for controlling a force applying direction, wherein a substantially polygonal plug end of the acting handle has a quick release structure comprising a sliding sleeve, an elastic member, a buckle, a top shaft and a latching bead, so that the sliding sleeve may be displaced to prop out the latching bead or sink the latching bead to achieve the effect of plugging an external connected assembling member securely or releasing the external connected assembling member quickly.

A customized tool adapter that allows for a typical wrench to be connected temporarily, but with great stability to a typical ratchet. Such an application is capable of being used with several types wrenches and ratchets, including various sizes, units of measurement and other applications and is generally hexagonal in nature having swaged gripping lips.

In some embodiments, a maintenance apparatus is provided for maintaining semiconductor processing equipment. The maintenance apparatus has an articulated member having a first member with a handle engagement portion and a second member with a first tool engagement portion. The first member is rotationally coupled to the first member about an articulation axis. A first tool member in selective engagement with the first tool engagement portion of the second member.
