Abstract

The invention provides a movable arc-shaped escapement jaw wrench which is provided with a wrench body, a clamping element, and an escapement jaw. The wrench body has a handle, a head, and a thumbscrew. The head is provided with a fixed jaw and an arc groove. The clamping element is connected to the wrench body and has a sliding bar, a ribbed slab, and a movable jaw. The escapement jaw is arranged in the arc groove of the head, and is provided with two sleeving sheets located on two sides of the ribbed slab; the escapement jaw is further provided with a top abutting snug, a clamping surface, a top pushing surface, an occlusion snug, an accepting hole and an elastomer. The movable arc-shaped escapement jaw wrench is convenient to rotate and has great structural strength.

Description

technical field [0001] The invention relates to an adjustable wrench, especially a movable arc-shaped escapement jaw wrench which is convenient to rotate and has good structural strength. Background technique [0002] The existing adjustable wrench is mainly provided with an arc-shaped moving track on the inner side of the fixed jaw, which is opposite to the rotation direction of the existing adjustable wrench. The reversible structure of the rotating shaft is used to cooperate with the movable jaw that moves up and down to achieve free reversing. And the use effect of clamping and driving the hexagonal head of the bolt when rotating clockwise. However, although the existing adjustable wrench can achieve the effect of using the hexagonal head of bolts in the same direction and reverse direction as well as adapting to different sizes, because its rotating shaft retracts into the head when the wrench reverses The trajectory inside is opposite to the direction in which the wren...
