Description

Technical Field

[0001] The invention belongs to the field of automobile maintenance and relates to a safety lifting and fixing device for automobile maintenance. Background Art

[0002] Automobile maintenance is a general term for automobile maintenance and repair, which means to use technical means to check the faulty automobile, find out the cause of the fault, and take certain measures to eliminate the fault and restore it to a certain performance and safety standard. Automobile maintenance includes automobile overhaul and automobile minor repair. Automobile overhaul refers to the restorative repair that repairs or replaces any parts (including basic parts) of the automobile to restore the good technical condition of the automobile and completely (or nearly completely) restore the life of the automobile. And automobile minor repair refers to the operational repair that guarantees or restores the working ability of the automobile by replacing or repairing individual parts.
