Abstract

The invention discloses a wrench for disassembling and assembling an external hexagonal head fastener in a narrow space and a using method, and aims to solve the problem that during lateral installation, disassembling and assembling of the external hexagonal head fastener in the narrow space with limitation in both height and width directions is inconvenient to complete by a conventional tool. Thewrench comprises a shell body, a driving chain wheel, a chain, a driven chain wheel and a cover plate, the shell body is in a hollow flat strip shape, the driving chain wheel and the driven chain wheel are fixed to the two sides in the shell body respectively, the chain is connected with the driving chain wheel and the driven chain wheel, the thickness of the driving chain wheel and the thicknessof the driven chain wheel are consistent with the height of the shell body, a second through hole is formed in the driving chain wheel in the axial direction and detachably connected with a power source, the driven chain wheel is provided with a first through hole in the axial direction, the size of the first through hole is consistent with that of the head of the outer hexagon head fastener, thecover plate is detachably connected with the shell body, a cavity is formed after the cover plate is connected with the shell body, and the transmission parts of the driving chain wheel and the driven chain wheel and the chain are sealed in the cavity. Meanwhile, the invention further provides a using method of the above scheme.

Description

technical field [0001] The invention relates to the technical field of hand tools, in particular to a dismantling wrench for external hexagon head fasteners in a narrow space and a use method. Background technique [0002] In the field of fastener installation, such as mechanical equipment installation or furniture assembly, due to the limitations of product structure layout and appearance requirements, it is often necessary to install screws and nuts in a small space, when there are restrictions in height and width It is especially difficult to install hexagon head screws or nuts sideways in tight spaces. [0003] At present, the commonly used tools for installing external hexagonal head screws and nuts include adjustable wrench, external hexagonal wrench, hexagonal socket wrench, etc. These tools are used to clamp the opposite side or hexagonal side of the external hexagonal head screw or nut when the operating space is open. Rotate operation, it is very convenient to ins...
