A hand tool structure has two plier bodies pivoted by a pivot member, and a knob mechanism for controlling opening and closing of the two plier bodies. Opposing sides of the two plier bodies each include a V-shaped groove to form a square clamping hole when the two plier bodies are closed; a row of teeth; a first cutting portion for cutting an electric wire or cable; a second cutting portion for cutting a metal wire; a wavy peeling portion having curved sections, wherein when the two plier bodies are closed, the curved sections form receiving holes with different diameters. The two plier bodies have first and second cutting holes for cutting screws. The first cutting hole includes a large diameter section and a small diameter section. The second cutting hole is greater than the large diameter section, and its extending direction is inclined relative to the first cutting hole.

A tool for disassembling a pipe or tube from a push-to-connect fitting and a method is provided. The tool includes a first body and a second body pivotally coupled to the first body. A pair of first fingers are pivotally coupled to the first body, each of the first fingers having a first semi-circular surface, the first semi-circular surfaces cooperating to engage the pipe or tube adjacent the collar. A pair of second fingers are coupled to the second body, each of the second fingers having a second semicircular surface, the second semi-circular surfaces cooperating to engage the push-to-connect fitting. Wherein with the first body is rotated from a first position to a second position, the pair of first fingers moves a fitting collar axially relative to the pipe or tube.

A tool jaw width adjustment structure includes a first plier body and a second plier body that cross each other. The first plier body has an elongated hole. One side of the elongated hole is provided with a toothed portion. The second plier body is provided with a cylindrical shaft inserting through the elongated hole. A distal end of the cylindrical shaft is provided with a side plate extending beyond one side of the toothed portion. A periphery of the cylindrical shaft is provided with a toothed block that is always meshed with the toothed portion. When the second plier body is pivotally opened relative to the first plier body, the toothed block is kept in mesh with the toothed portion, and the cylindrical shaft is driven to roll in the elongated hole from a first position to a second position, so as to increase the width of the jaw.

A pliers includes a first body with an engaging groove and a second body with an elongated slot pivotally connected with each other. The elongated slot includes a left and right positioning grooves and a protruding portion disposed therebetween. A tap button is pivotally connected to the second body. A supporting member is disposed between the second body and the tap button. When the first body comes close to the second body, the tap button can be tapped to a first position and engaged in the engaging groove. Thus, the first body is blocked and cannot pivot relative to the second body. The tap button can be tapped to a second position and detached from the engaging groove. Thus, the first body is pivotable relative to the second body. A positioning block is extending from the tap button and can be engaged in any of the positioning grooves for positioning the tap button.

Adjustable locking pliers includes a lock assembly, a jaw pressure adjustment wheel for adjusting the clamping pressure and a cam plate.

Adjustable locking pliers includes a lock assembly, a jaw pressure adjustment wheel for adjusting the clamping pressure and a cam plate.

A locking pliers includes a pliers-body, a rotating shaft and an operating and pivoting unit. The pliers-body includes a fixed jaw, a movable jaw and a jaw end member disposed on the movable jaw. The rotating shaft is rotatably connected with the fixed jaw about a pivot axis and is movable along the pivot axis, and has clamp and insert ends. A clamp member is disposed on the clamp end. A pivot member extends through the fixed jaw and connected with the rotating shaft and is operable to move the rotating shaft close to or away from the fixed jaw. A retaining member extends through the fixed jaw and the rotating shaft to retain the rotating shaft to a first or second position. With the rotating shaft rotated between first and second positions, the locking pliers can be shifted to two types of use.

A fishing tool includes a main body and a holding assembly coupled to the main body. The holding assembly includes a bottom holding jaw and a top holding jaw rotatably coupled to the bottom holding jaw and movable relative to the bottom holding jaw between an open holding position and a closed holding position to selectively hold a fish hook in place. The holding assembly is rotatable relative to the main body and configured to be secured relative to the main body in a fixed number of positions.
