A clamp, including a first clamp body and a second clamp body. The first clamp body includes a first clamp jaw and a first handle, movably connected to each other. The first clamp jaw is rotatably connected to the second clamp body at a first connecting position, and the first handle is rotatably connected to the second clamp body at a second connecting position. When the relative position of the first clamp jaw and the first handle is changed, a force occurs between the first clamp jaw and the first handle. A moment formed by the force with the first connecting position as a fulcrum is greater than a moment formed by the force with the second connecting position as a fulcrum.

The present invention discloses a pair of adjustable pliers, comprising a first handle and a second handle, both of which have a gripping part arranged at a front end thereof, the two gripping parts forming a jaw span, the first handle and the second handle being arranged in an intersectional manner and relatively fixed via a connecting mechanism, wherein the second handle has an elongated rack slot at a position of the connecting mechanism, and the rack slot is provided with a toothed rack on an inner side part thereof. The connecting mechanism comprises a positioning snap piece arranged inside the rack slot and a link mechanism connected with the positioning snap piece, the positioning snap piece has lateral teeth which are engaged with the toothed rack on the rack slot, the link mechanism is provided to drive the positioning snap piece to rotate and disengage the lateral teeth on the positioning snap piece from the toothed rack. Thus the first handle can move relative to the second handle along the rack slot through the movement of the connecting mechanism. The link mechanism comprises a trigger shaft connected with the positioning snap piece, and the trigger shaft has a trigger part thereon. The present invention has the advantages that the right handle can be directly pushed to achieve the quick one-way adjustment, which is convenient and saves effort compared to the ordinary water pump pliers that need two-handed adjustment.

A pliers has guiding surfaces at tooth portions of the first pliers body and tooth portions of the engaging unit of the control member. Therefore, when the pressing block of the control member is not pressed, even if the first pliers body is engaged with the tooth portions of the engaging unit, the second pliers body can still be pushed forward relative to the first pliers body, so that the second guiding surfaces of the second tooth portions of the engaging unit slide relative to the first guiding surfaces of the first tooth portions and each of the first tooth portions is moved to engage with a next corresponding second tooth portion, thereby allowing the second pliers portion being movable toward the first pliers portion. Hence, the clamping distance of the pliers can be adjusted to match with an object to be clamped.

Disclosed is a tool, such as pliers, with handle offsets and stop features. In an embodiment, the tool has a minimum of about 0.50 inches of clearance between handles in an area where a user's index finger contacts the handles. This is accomplished by offsetting upper and lower handles of the tool. For example, the lower handle may be offset about 1.10 inches from a pivot point between the handles. Similarly, an end of the upper handle may be offset by about 1.150 inches from the pivot point when jaws of the tool are adjusted to a closed position.

Disclosed is a tool, such as pliers, having a reduced spacing between adjustment teeth, and an elongated slot; thereby providing an improved adjustability and larger capacity to hold workpieces. In particular, the spacing of the adjustment teeth and length of the slot provide more adjustment positions and allow more teeth to be engaged at all positions. For example, the teeth may be spaced at 0.098 inches and the tool may provide a maximum jaw opening of 2.24 inches.

Disclosed is a tool, such as pliers, having reduced spacing between teeth extending into a slot on a handle of the tool. This provides improved adjustability and a larger capacity to hold work pieces. The design, spacing of the adjustment teeth and length of the slot provide more adjustment positions and allow more teeth to be engaged at all positions. In an example, the teeth are spaced at about 0.066 inches and the tool has a maximum jaw opening of about 2.28 inches.
