Abstract

The invention provides an adjustable spanner and belongs to the technical field of hardware tools. Adjustment of the jaw size can be directly achieved by arranging a first threaded rod and a first screw hole which are used in cooperation so that the adjustable spanner can adapt to fasteners in different sizes, and operation is convenient. By arranging a first wrenching head, a jaw can clamp the fastener more tightly. Meanwhile, by arranging a first radial groove in a first contact face, on the one hand, rust, oil-water and other impurities on the surface of the fastener can be scraped into thefirst radial groove, so that the jaw can clamp the fastener more tightly, and the adjustable spanner is not prone to sliding off; and on the other hand, the first contact face of a first jacking column is divided into four parts, it can be guaranteed that at least two parts tightly jack the two sides of the side face of the fastener, torque is transmitted better, even though a number of impurities still exist on the side face, the movable amount between the jaw and the fastener cannot be caused too much, the situation that the adjustable spanner slides off in the using process and fastener thread slipping occurs is further avoided, and the situation that a user is hurt is also effectively avoided.

Description

technical field [0001] The invention belongs to the technical field of hardware tools, and more specifically relates to an adjustable wrench. Background technique [0002] Adjustable wrench, also called adjustable wrench, is often used in daily work. It is a tool with adjustable jaw size and used to tighten or loosen fasteners such as angled screws or nuts. When the existing adjustable wrench is used to disassemble the nut, since the nut and other fasteners will be rusted, soaked in oil or water during use, when disassembling it, due to the barrier of rust, oil and water, and the active The wrench itself clamps the nut in the form of the combination of the worm gear and the rack. It is often difficult to completely clamp the nut with its movable jaws, and there is often a certain amount of activity, which makes the adjustable wrench slip easily when the nut is disassembled or tightened forcefully, causing the nut to slip squarely. , and even the problem of bruising the arm....
