Torque adapter for a cable connector that expands to fit connector nuts of different sizes. The adapter fits around the cable connector and engages three of the corners of a hex nut with matching recessed regions in its inner surface. It has three slots that receive the other three corners of the connector nut. The adapter is flexible so that the slots may widen to accommodate connector nuts of larger widths. The outer surface may be hexagonal so that a wrench or similar tool may be used to turn the torque adapter.

A chain wrench which utilizes ordinary high-speed drive chain to form an adjustable, replaceable chain wrench of unlimited length potential. A sprocket for gripping at the head of the wrench, and allows the chain to nearly completely wrap about the object to be turned or held, preventing the need for a gripping portion which tends to damage or crush the object being turned or held. Multiple such chains could be used simultaneously.

A strap wrench is used to drive a cylindrical object and contains: a handle including two recesses and a longitudinal slot; a strap including a first end portion and a second end portion which are inserted into the two recesses; a guiding rod longitudinally inserted into the handle; a supporting block rotatably connected with a first segment and located inside the strap; a movable member disposed on the guiding rod and moving between a first position and a second position, the movable member joining with the strap; a push switch slidably fixed in the longitudinal slot and rotatably connected with the movable member; and a spring for pushing the movable member to move toward the second position. Thereby, the movable member is driven by the engaging block to move between the first position and the second position so as to operate the strap wrench easily.

A one-way drive strap wrench has a handle, a threaded rod module mounted in the handle and a clamping module mounted in the handle. The clamping module has an asymmetric clamping block and a strap. The clamping block is mounted around a combining unit of the handle and has an accommodating trough accommodating a pushing segment of the threaded rod module, wherein the accommodating trough is wider than the pushing segment. The strap is circled around the clamping block to form a surrounded area. A crossing angle is formed between the axis of the handle and the blocking line and is smaller than 90 degrees.

A revolving screwdriver with ratchet structure includes a handle, a pushing rod, and a sliding member. The sliding member has a receiving space and a holding chamber defined therein. A revolving cylinder is received in the holding chamber. The receiving space receives at least one ratchet wheel, two rotators, a limiting member, a base, and an adjuster. The at least one ratchet wheel engages with a driving shaft. The rotators selectively engage with the at least one ratchet wheel. The limiting member locates between the rotators and has a protrusion formed thereon. A base has a first guiding slot defined therein. The adjuster has a driving hole defined therein. The protrusion passes through the first guiding slot and the driving hole for being driven by the adjuster and moving along the first guiding slot.

An adapter for installing a connector to a terminal post, wherein the connector is attached to a cable, is presented. In an embodiment, the adapter is comprised of an elongated collet member having a longitudinal axis comprised of a first collet member end, a second collet member end, an outer collet member surface, and an inner collet member surface. The inner collet member surface at the first collet member end is used to engage the connector. The outer collet member surface at the first collet member end is tapered for a predetermined first length at a predetermined taper angle. The collet includes a longitudinal slot that extends along the longitudinal axis initiating at the first collet member end for a predetermined second length. The first collet member end is formed of a predetermined number of sections segregated by a predetermined number of channels and the longitudinal slot.
