Abstract: An adjustable wrench is disclosed. The adjustable wrench is used for an assembly part. The adjustable wrench includes a frame and an adjustable member. An inner side of the frame has a first rack. The adjustable member has a second rack meshed with the first rack. The adjustable member and the frame are meshed with each other by the first rack and the second rack such that the adjustable member forms a first space inside the frame, wherein the adjustable member adjusts a meshing position of the second rack and the first rack to change the size of the first space; thus, the first space can match assembly parts of different specifications.

Abstract: A multifunctional hand tool is provided, having an adjustable wrench head and an elongated handle extending from the wrench head. The handle is oriented transverse to the wrench head and that defines a plurality of wrench apertures of different sizes. Each wrench aperture defines an axis of rotation for operable use oriented substantially transverse to the first axis of rotation. The wrench head further comprises a hammer and the elongated handle further comprises a nail pull structure. The wrench head can further include a grip texture on an outer surface thereof to facilitate use of the wrench apertures or the nail pull defined by the wrench handle. The outer surface of the handle further includes grip features or textures to facilitate use of the hammer. The adjustable wrench can be changed to a pipe wrench.

Abstract: A pivot head wrenching tool includes a handle, a switch, a pawl, a torsion spring, and a pivotal driving head. The pivot head wrenching tool is operable in a lock mode in which the pivotal driving head is restrained from being pivoted and in an unlock mode in which the pivotal driving head is able to be pivoted. The switch is in a first position and includes a first surface abutted against the pawl as well as the pawl is engaged with a connecting end of the pivotal driving head when the pivot head wrenching tool is in the lock mode. The switch is in a second position and includes a second surface gapped from the pawl as well as the pawl is disengaged from the connecting end of the pivotal driving head when the pivot head wrenching tool is in the unlock mode.

Abstract: An open end wrench includes a fixed jaw, the fixed jaw having a dovetail tongue and a U-groove extended along the width thereof, a sliding groove formed in the dovetail tongue, and a stop block with a pin disposed at one end of the U-groove, a movable jaw, the movable jaw having a dovetail groove coupled to the dovetail tongue, a stop rod perpendicularly inserted into the sliding groove and movable with the movable jaw along the sliding groove, and a stop block with a pin disposed at one end of the U-groove, and a spring member received in the U-grooves of the fixed jaw and movable jaw and supported with the two ends thereof on the pin at the stop block of the fixed jaw and the pin at the stop block of the movable jaw.

Abstract: The universal wrench has a handle and a wrench body with reciprocally displaceable jaws and part-gripping teeth. An abutment end portion of the handle has circularly arranged teeth that cooperate with teeth on a rack provided on one of the jaws. The rack is reciprocally guided in the other jaw. A spring is secured to the handle and to this other jaw. A latch pin presses against the lower circular surfaces of this other jaw to secure the handle in different pivoting positions.

Abstract: An adjustable wrench including a fixed jaw, a movable jaw, a gear, an engaging block, a switch button and a grip. When tightening or untightening a nut with the adjustable wrench, it is unnecessary to repeatedly draw up the wrench and fit the wrench onto the nut. The nut can be continuously rotated. In addition, the switch button can be switched to change the rotational direction without reversing the adjustable wrench so as to facilitate operation and increase working efficiency.

Abstract: A wrench of the type having one handle produced by the manufacturing processes of drop forging and machining, incorporating a pivot point that acts as a fulcrum for a cam member that is integral with a wormwheel segment. The cam member terminates in the recess of a moveable jaw member which provides the surface for the cam to advance or retrack the jaw member toward or away from a fixed jaw that is integral with the handle member. The wormwheel is meshed with a worm gear member that can be rotated, advancing or retracking the moveable jaw member toward or away from a fixed jaw that is integral with the handle member.

Abstract: A dual-purpose adjustable wrench is comprised of a wrench body, a movable jaw unit and a worm gear rack mechanism for providing a rapid adjustment of the wrench. The wrench is further comprised of a clutch unit to enable the jaw opening to be quickly adjusted. The movable unit comprises a toothed element hinged at one of lateral sides of the movable jaw. The wrench can be alternated to function as a pipe wrench by removing the movable jaw unit, reversing and inserting it back into the wrench body.

Abstract: Pliers comprising a stationary pliers member (10) with associated first jaw member (11) and a moveable pliers member (12) with associated second jaw member (13). Jaw member (13) of the moveable pliers member is moveable towards and away from jaw member (11) of the stationary pliers member by means of an actuating handle (21) pivotable relative to the stationary pliers member (10). The second jaw member (13) is moveable towards the first jaw member (11) in a two-step movement, that is to say with a first movement with relatively long length of movement and with relatively little force by means of a first actuating means (17, 19) between the actuating handle (21) and the moveable pliers member (12) and with a second movement with relatively short length of movement and with relatively large force by means of a second actuating means (26) between the actuating handle (21) and the moveable pliers member (12).

Abstract: An adjustable wrench in which a slidable jaw is biased away from a fixed jaw, toward a fully-open position, by the force of a biasing spring, and a pawl and ratchet mechanism locks the slidable jaw, against the biasing force of the biasing spring, in any selected one of a plurality of positions relative to the fixed jaw and enables selective release of the slidable jaw for movement to the fully-open position in response to the biasing force of the biasing spring.

Abstract: An adjustable wrench having a shank forming a handle and provided with a fixed jaw toward and away from which slides a movable jaw mounted on the shank. The movable jaw is selectively locked in a desired position relative to the fixed jaw by a lock arrangement including a latch disposed on the shank for movement substantially relative to the movable jaw and provided with teeth which can engage teeth provided on the movable jaw.

Abstract: A wrench having a body portion with a handle and an inclined sliding jaw, and a movable jaw having a ratchet toothed shank received in a channel in the body portion, and a spring-biased pawl comprising a saddle straddling the shank pivotally mounted on the body of the wrench and carrying a ratchet toothed element which wedges into the channel between the body portion and the shank, engaging the ratchet teeth of the shank to limit separation of the jaws.
