Embodiment Construction

[0051] The invention provides a movable arc escapement jaw wrench, such as Figure 1 to Figure 5 The first preferred embodiment shown includes:

[0052] A wrench body 10 is provided with a handle 11, which is a long handle extending in the front and rear directions and has front and rear ends and upper and lower sides. A wrench head 12 is connected to the front end of the handle 11. 12 is a connecting block 121 that extends forward from the handle 11. The connecting block 121 is a plate with a wide front and a narrow front and a flat shape in the front. It also extends forward on the upper side of the connecting block 121 to form a fixed Jaw 122; the wrench head 12 is recessed to form an arc-shaped groove 123 on the upper side in front of the connecting block 121 and the rear side under the fixed jaw 122. The inner wall of the arc-shaped groove 123 can be a single or an arc with multiple centers State, and the two ends of the arc-shaped groove 123 are divided into a reverse end ...

Abstract

An adjustable wrench has a wrench body, a clamping element and a ratcheting jaw. The wrench body has a handle, a head and a thumbscrew. The head is formed on a front end of the handle and has a connecting block, a fixed jaw, a curved slot, a positioning pin, a mounting recess and a sliding slot. The clamping element is movably connected to the wrench body and has a rear end, a front end, a sliding bar and a movable jaw. The sliding bar is formed on the rear end of the clamping element, is mounted in the sliding slot and engages the thumbscrew and has multiple teeth. The ratcheting jaw is a curved block capable of sliding forward and retracting backward inside the curved slot and has a backward area, a forward area, a guide hole, an engaging surface, an abutting surface, an engaging protrusion and a spring. The adjustable wrench can hold a hexangular head of a bolt securely and can be operated with bolts of different sizes smoothly.

Description

Technical field [0001] The invention relates to an adjustable wrench, in particular to a movable arc escapement jaw wrench. Background technique [0002] Existing adjustable wrenches, such as US Patent No. 6739223 "Rotating Axis Adjustable Wrench" patent, are equipped with a rotating shaft with an arc-shaped movement track opposite to the direction of rotation of the wrench on the inner side of the fixed jaw of the adjustable wrench. The movable jaw that moves up and down achieves the effect of freely reversing and clamping and driving the hexagonal head when rotating forward. [0003] Although the aforementioned existing adjustable wrench can achieve the effect of forward and reverse rotation and adapt to the use of different sizes of hexagonal heads, because the trajectory of its shaft retracts and enters the head when the wrench is reversed, the direction of rotation of the wrench is opposite. Smaller moving range allows smoother rotation. [0004] In addition, because the "rota...
