Special tool for removing and installing the fuel tank cap

Abstract

The invention provides a special tool for mounting and demounting of an oil tank cover. The special tool comprises a disc, an operating handle, and a plurality of inserts. The disc comprises an upper surface and a lower surface and is provided with a plurality of observation holes, wherein the observation holes passing the upper and lower surfaces are used for observing the oil tank cover. The operating handle comprises a first end and a second end. The first end is fixedly connected to the center of the disc. The second end is used for connecting an external actuator providing torque. The inserts are fixed to the lower surface or peripheral side of the disc directly or indirectly. The inserts are evenly arranged along the periphery of the disc. Each insert comprises a third end adjacent or fixed to the disc and a fourth end opposite to the third end. A shift part of each insert, close to the fourth end, is adaptably butted to a vertical rib on the radial periphery of the oil tank cover and is used for applying the torque to the oil tank cover. The special tool composed of the disc, the operating handle and the inserts only is simple in structure and small in size; the problem that the existing mounting and demounting tool for oil tank covers is large in size and heavy is solved.

Description

technical field [0001] This patent relates to the technical field of automobile assembly and maintenance, in particular to a special tool for disassembling and assembling a fuel tank cap. Background technique [0002] At present, there is no special tool for removing and installing the fuel tank cap on the market, so a hammer is generally used to knock the vertical ribs of the fuel tank cap for disassembly and assembly. Such an operation method will inevitably cause varying degrees of damage to the outer surface of the fuel tank cap, and the disassembly and assembly efficiency is very low due to the inconvenience of disassembly and assembly. [0003] In order to solve the above problems, some automobile assembly factories have produced simple fuel tank cap removal tools, but due to the large size and cumbersomeness of such tools, not only cannot realize the operation of twisting force (adding a specified rotational force to the acting object such as a bolt), but also Not su...
