Description

Engine oil extraction mechanism for automobile maintenance Technical Field The utility model relates to the technical field of automobile maintenance, in particular to an automobile maintenance engine oil extraction mechanism. Background When the automobile is maintained, most of the engine oil is replaced by gravity, a maintainer needs to drill to the bottom of the automobile, unscrew an oil discharging screw, and the like, so that the old engine oil slowly flows out. The method is simple and direct, but has the defects that firstly, a vehicle can only use a lifting tool specialized in a maintenance workshop to lift the vehicle, maintenance personnel can not change engine oil by the vehicle owner, secondly, the design of engine oil bottom shells of different vehicles is different, for example, oil discharge ports of some vehicles are not at the lowest point or baffles are arranged in the engine oil bottom shells, so that more old oil remains, thirdly, chassis guard plates of some vehicles are particularly difficult to detach, screws can rust and twist, even the positions are very awkward, the operation is time-consuming and labor-consuming, and an oil discharge screw can damage a gasket every time the oil discharge screw is detached, so that the risk of oil leakage is caused. Obviously, the gravity oil change mode is not friendly to the vehicle owner, and can not meet the requirement of the vehicle owner for automatically changing engine oil. Disclosure of utility model The utility model provides an engine oil extraction mechanism for automobile maintenance, which has reasonable structural design, convenient operation, time saving and labor saving, adopts hand-operated extraction operation, enables an automobile owner to smoothly extract engine oil independently without lifting the automobile, is green, energy-saving and emission-reducing, can adjust extraction points, is suitable for different engine oil bottom shells, effectively reduces the residual oil quantity in the engine oil bottom shells, simultaneously does not damage chassis guard plates and gaskets, avoids the risk of oil leakage, can meet the daily requirement of the automobile owner on the maintenance of the automobile, and solves the problems in the prior art.
