The invention relates to the field of pneumatic vacuum suction, in particular to a self-adaptive vacuum suction device which comprises a cylinder cover assembly, a sawtooth rotating disc, a cylinder barrel, a sawtooth piston, a rotating disc spring and a suction cup assembly. The sawtooth rotating disc is installed in the cylinder cover assembly and rotates in cooperation with the cylinder barrel, and the rotating disc spring is placed between the sawtooth rotating disc and the cylinder cover assembly. The sawtooth piston is sleeved with the cylinder barrel, and the suction cup assembly is installed at the bottom end of the sawtooth piston, so that the sawtooth piston and the suction cup assembly move up and down in the cylinder barrel. The cylinder cover assembly, the cylinder barrel, the sawtooth piston and the suction cup assembly jointly form an inner containing cavity. According to the device, vacuum can be generated to suck a workpiece by operating and changing the volume of the inner containing cavity,
