The automatic simple quantitative special packaging device for the cosmetics comprises a machine body, wherein a fixed plate, a discharging box, a clamping frame, a rotating shaft and an operation table are arranged inside the machine body; a connecting block is arranged on the front surface of the fixed plate; a movable rod is movably arranged below the connecting block; one end, far away from the connecting block, of the movable rod is movably connected with a connecting rod; and a movable block is movably arranged below the connecting rod. According to the automatic cosmetic simple quantitative special packaging device for the cosmetics, the rotating shaft is driven to rotate through a power supply, two symmetrical convex blocks are arranged below the movable block, a clamping block is arranged above the rotating shaft, when the clamping block on the rotating shaft rotates to the position of the left side convex block, the left side convex block is driven to move upwards so as to drive the right side of the movable block to deviate downwards, at the moment, a piston opening of a discharging pipe below the discharging box is opened, so that a product falls onto the operation table, automatic quantitative discharging is realized, and therefore the working efficiency is improved.
