A hole drilling jig assembly for drilling holes in a support at a precise location includes a pair of locking pliers that include a pair of jaws and an adjustment screw. An eyebolt is coupled to the adjustment screw and a pulling line may be coupled to the eyebolt for pulling on the locking pliers. A pair of panels is each coupled to a respective one of the jaws. Each of the panels is compressed against a support when the locking pliers are closed. Each of the panels has a pair of apertures extending therethrough to facilitate holes to be drilled through the support at a precise location.

Universal pliers contains: a first jaw, a second jaw, a first lever, a second lever, and a connection extension. The first jaw and the second jaw are rotatably connected, the first lever is one-piece formed on the first jaw, the second lever is rotatably connected on the second jaw, a first end of the actuation extension is rotatably connected on the second lever, a second end of the actuation extension is rotatably connected in the first lever, and the actuation extension includes a bending section. The first lever includes a slide block and a spring which are accommodated on the first lever, a first side of the slide block abuts against the actuation extension, a first end of the spring is biased against a second side of the slide block, and a bottom of the first lever is screwed with a screw bolt which contacts with the spring.

A pliers is provided, including a main body, a slidable member, a swingable assembly and a clamp assembly. The slidable assembly is attached to the main body. The swingable assembly includes a swingable member and a connecting member, and the swingable member is pivoted to one of two ends of the slidable member and one of two ends of the connecting member. The clamp assembly includes a firs clamp portion and a second clamp portion, and the first clamp portion is disposed on the slidable member.

The present invention discloses a ratchet clamp comprising a first clamping arm and a second clamping arm which are pivotally connected with each other via a connecting shaft so as to be opened and closed relative to each other, a ratchet assembly, a swing assembly and a control assembly provided between the first clamping arm and the second clamping arm; the ratchet toothed assembly has a plurality of first ratchet teeth and a plurality of second ratchet teeth which are juxtaposed and are misaligned with each other; the swing assembly and the ratchet toothed assembly are moved away from or towards each other with the connecting shaft as the axial center of rotation; a latch member of the control assembly has at least a first pawl and at least a second pawl, a wrench member of the control assembly is used for toggling the latch member to be moved, the first pawls and the second pawls are respectively engaged with the corresponding first ratchet teeth and second ratchet teeth when the latch member is moved to an engaged position, and the first pawls and the second pawls are respectively moved away from the corresponding first ratchet teeth and the second ratchet teeth when the latch member is moved to a released position. With the misaligned ratchet tooth design, the tooth profile may not be reduced, thereby increasing the structural strength, so that the overall clamping force is greatly enhanced.

A manual clam plug connector to connect a plug connector, the manual clam plug connector including a vice-grip locking pliers disposed at a first end of the manual clam plug connector to be squeezed manually, and a connecting clam disposed at a second end of the manual clam plug connector to be squeezed in response to the vice-grip locking pliers being squeezed, such that a female connector end of the plug connector and a male connector end of the plug connector are brought together in response to the connecting clam being squeezed.

A locking pliers preferably includes a fixed jaw, a moveable jaw, a fixed handle, an adjusting screw, a toggle link, at least one power link, a curved link and a moveable handle. The fixed jaw is retained in a first end of the fixed handle. The moveable jaw is pivotally retained in the first end of the fixed handle. An adjustment screw is retained in a second end of the fixed handle. An end of the adjustment screw engages a first end of the toggle link. The moveable handle is pivotally engaged with the toggle link and a first end of the curved link. A first end of the power link is pivotally engaged with a second end of the toggle link. A second end of the curved link is pivotally engaged with the power link. The moveable jaw is pivotally engaged with a second end of the power link.

A clamp that is used for clamping a flexible tube or hose has two primary pieces that are hinged together at one end and have handle sections on the other end. Two linking pieces that are hinged together at one end have opposite ends that are hinged to intermediate hinge points on the primary pieces. Clamping surfaces on one of the primary pieces and on one of the linking pieces open in the direction of the handles. When rotating to the closed position, the intermediate hinge point on one of the primary arms moves from one side of a line that runs between the point where the primary pieces are hinged and the point where the linking pieces are hinged to the other side of that line, providing a locking action.

A crimping tool is provided. The crimping tool includes a movable jaw. The jaw being movable from an open and crimped positions. In an embodiment a linkage is coupled to the jaw and is rotatable about an axle. A member is provided having at least a first and second gear portion, the member pivoting about the linkage and moving relative to the main axle as the jaw moves from the open to the crimped position. A ring gear is coupled to the second gear portion and cooperate therewith to rotate the member about the axle. A drive gear rotates about the axle and cooperates with the first gear portion cooperating to rotate the member relative to the linkage. A handle is pivotally coupled to the axle. A drive pawl is coupled to the handle and rotates the drive gear in response to the handle moving from a first to a second position.

A push fitting tubing remover is provided, comprising a locking grip wrench portion, and upper and lower disassembly clip portion. The locking grip wrench portion has an upper jaw portion and a lower jaw portion. The upper disassembly clip portion extends from the upper jaw portion of the locking grip wrench portion and has a first circular groove portion having a first diameter and a first thickness configured to enclose a first cylindrical object. The lower disassembly clip portion extends from the lower jaw portion of the locking grip wrench portion and has a second circular groove portion having a second diameter and a second thickness. The upper disassembly clip portion and the lower disassembly clip portion are parallel when gripping the first and second cylindrical objects with a gap therebetween. The upper and lower disassembly clip portions are configured to disassemble a tubing from a push fitting connector.

Embodiments are directed to a wood clamp that grips two perpendicularly arranged boards. A pair of gripping elements having planar surfaces may define a gripping jaw that is moveable to grip a first board A lateral support member may extend from a spacer orthogonally from a longitudinal direction of the pair of gripping elements and may define a projection. The projection may be configured to prevent sliding of a second board supported by the lateral support member and abutting the first board. A lockable handle assembly coupled with the pair of gripping elements may be configured to manipulate an offset between the pair of gripping elements by moving at least one of the pair of gripping elements and locking a position of the planar surfaces to maintain the offset using a linkage.
