A four-eye wrench

Abstract

The invention discloses a four-eye wrench, which comprises a wrench rod and a wrench head. Two wrench heads of different specifications are fixedly connected to both ends of the wrench rod. Two plum blossom-shaped sleeves of different specifications are arranged at both ends of each wrench head in the length direction. The wrench rod is a folding structure and folds towards the length direction of the wrench head. The wrench head at both ends of the four-eye wrench of the present invention has an integrated structure, good rigidity, high strength, and good connection reliability after contacting with the nut or screw to be disassembled, and the handle with a folding structure is convenient for folding and using in special narrow occasions, increasing the The scope of application of the wrench is more convenient to operate, and it is also convenient to store and place. After folding and bolting the two wrench heads, it is hooked to the anti-trip buckle of the belt, which is especially suitable for high-altitude operations.

Description

technical field [0001] The invention relates to a four-eye wrench, which belongs to the technical field of wrenches. Background technique [0002] In the maintenance and installation of power transmission, transformation and distribution, all kinds of wrenches are most commonly used, such as adjustable wrench, ring wrench, open-end dead wrench and socket wrench. For the space inside the equipment is too narrow, conventional combination tools ( Combination sleeve), open-end wrench, ring wrench, and movable wrench cannot carry out the operation of disassembling and assembling bolts, which will cause work delays. The fewer tools you need to carry, the better. For example, Chinese patent application (application number 2009202861813) discloses a combined double-sided socket wrench, which includes a handle, and a ring is fixedly connected to both ends of the handle. At least one ring is arranged in each ring. Double-sided sleeve, this structure fixes the sleeve through the ring,...

Problems solved by technology

[0002] In the maintenance and installation of power transmission, transformation, and power distribution, various types of wrenches are most commonly used, such as adjustable wrenches, ring wrenches, open-end dead wrenches, and socket wrenches. For the narrow space in the equipment, conventional combination tools ( Combined sleeve), open-end wrench, ring wrench, and movable wrench cannot perform the operation of disassembling and assembling bolts, resulting in work delays. In the process of transmission, transformation, power distribution maintenance, and installation, especially for high-altitude operations The fewer tools you need to carry, the better. For example, Chinese patent application (application number 2009202861813) discloses a combined double-sided socket wrench, which includes a handle, and a ring is fixedly connected to both ends of the handle. At least one ring is arranged in each ring. Double-sided sleeve, this structure fixes the sleeve through the ring, which is easy to cause a gap between the sleeve and the ring, especially when there are multiple sleeves, the more the gap is, the less reliable the connection is during the assembly and disassembly of the nut or screw. Moreover, the handle is too long during use, making it unusable and inconvenient to store and place
