摘要： A tool with a pivoting head is shown. The tool includes a locking mechanism that allows the angular position of the head to be locked securely in place once selected by a user. The locking mechanism may be used with a variety of tools, such as ratchet wrenches, that allow for repositioning of the head relative to the handle of the tool.

摘要： A hand tool includes a handle and a head which includes a protrusion having a toothed portion. The handle includes a connection portion formed on one end thereof. Two lugs extend from the connection portion to form a recess between the two lugs and the connection portion. Two ribs respectively extend from the connection portion and ARE located between the two lugs. The two ribs are integral with the two lugs and the connection portion. The protrusion of the head is pivotably connected between the two lugs and the toothed portion is engaged with a control unit located in the recess. The two ribs restrict the angle that the head is pivoted relative to the handle.

摘要： A work tool includes a tool handle assembly that is moveable between an open default position and a closed working position. The tool handle assembly is constructed with an upper tool handle assembly and a lower tool handle assembly where the upper tool handle assembly and the lower tool handle assembly are configured to be snap-fit together to enable pivotal movement between the upper tool handle assembly and the lower tool handle assembly. The tool handle assembly further includes an attack angle orientation assembly carried partially by the upper tool handle assembly and carried partially by the lower tool handle assembly to facilitate pivotally closing a pair of cutting blades to operate on a work piece; the cutting blades are carried into alignment with a cutting blade plane defined by an imaginary cutting plane line extending between proximal end portions of the upper tool handle assembly and the lower tool handle assembly to prevent the pair of cutting blades from over-cutting a work piece beyond the cutting blade plane. The tool handle assembly further includes a biasing member which is secured between the upper tool handle assembly and the lower tool handle assembly in order to bias the tool handle assembly to an open default position and in order to bias the pair of cutting blades into an object receiving open position.

摘要： A pinch-off pliers possessing a canted orientation along the length. The pinch-off pliers has a first clamping unit, a second clamping unit, and an axial mechanism. The pinch-off pliers positioned along a first axis and a second axis, where the first axis is not parallel to the second axis. An intersection of the first axis and the second axis along the length of the pinch-off pliers creates a canting angle theta in the pinch-off pliers at the intersection. An intersection of a first plane and a third plane creates a second canting angle omega when having the pinch-off pliers positioned along the first axis and an intersecting fourth axis.

摘要： A ratchet wrench having a flexible positioning structure includes a drive bar, a rotary head, and a locking button. The drive bar includes a fork arm, an axial hole, and a radial hole communicating with the axial hole. The rotary head is pivotally connected to the fork arm; the rotary head includes a round housing, a plurality of positioning recesses disposed on the round housing, and a pivot axis passing through the rotary head and two ends of the fork arm. The pivot axis is perpendicular to the radial hole. The locking button includes a flexible fastener inserted through the radial hole and a latch bar disposed in the axial hole. The flexible fastener is flexibly movable in association with movement of the latch bar, so that the latch bar is engaged with or released from any of the positioning recesses.

摘要： A dual purpose flip-out and T handle ratchet is able to be used in an L or modified L-handle orientation as well as a T handle orientation. The dual purpose flip-out and T handle includes a handle portion and a ratchet head and neck portion. The handle portion is coupled to the neck portion at a lockable hinge. The hinge allows the head and neck portion to rotate to an L or modified L-handle orientation or to a T handle orientation. When properly oriented the tool is able to be used to tighten or loosen objects such as screws or bolts.

摘要： A hand tool includes a first body, a locking member and a second body. The first body has a function end, a pivotal hole, a first toothed portion, a first groove, a second groove and a first restriction groove. The locking member has a second toothed portion, a second restriction groove, a first connection portion, a restriction member, an engaging member and a resilient member. The second body has a third connection portion connected to the first connection portion to connect the first and second bodies. When the locking member moves to a first position, the engaging member is engaged with the first groove. The first toothed portion is engaged with the second toothed portion. When the locking member moves to a second position, the engaging member is engaged with the second groove. The first toothed portion is disengaged from the second toothed portion.

摘要： A socket wrench includes a head unit with two lug members, a tubular shaft, a handle rod, a first spring-loaded member disposed to permit the tubular shaft to be rotatably engaged with the head unit, and a second spring-loaded member disposed to permit the handle rod to be slidably engaged with the tubular shaft. The handle rod has front and rear end segments each having a cavity configured such that when the handle rod is displaced to a forward or rearward position, the second spring-loaded member is engaged therein, and such that when the handle rod is moved away from the forward or rearward position, the second spring-loaded member can slide out of the cavity.
