The invention discloses an automatic leveling system for a telescopic folding arm pallet fork of a forklift. The automatic leveling system comprises a leveling oil cylinder, a pallet fork overturning oil cylinder, a folding arm overturning oil cylinder, a one-way balance valve, a first two-way balance valve, a second two-way balance valve, a multi-way valve, a telescopic arm structure, a folding arm structure, a pallet fork assembly and a forklift body. A large arm of the telescopic arm structure is connected with the forklift body in the mode that the large arm can rotate around an A'point, the O 'end of the leveling oil cylinder is hinged to the forklift body, and the C' end of the leveling oil cylinder is hinged to the large arm. The O end of the pallet fork overturning oil cylinder and the head end of the folding arm structure are connected with the end of a telescopic auxiliary arm of the telescopic arm structure in the mode that the O end of the pallet fork overturning oil cylinder and the head end of the folding arm structure can rotate around the O point, the C end of the pallet fork overturning oil cylinder is hinged to the pallet fork assembly, and the pallet fork assembly is connected with the tail end of the folding arm structure in the mode that the pallet fork assembly can rotate around the A point. The automatic leveling device is high in flexibility during operation, and has an automatic leveling function aiming at different working conditions.
