The device includes a trigger rod, and the trigger rod is L-shaped. Four groups of moving rods are disposed outside an inner rod, the moving rods are diamond, and the moving rods are made of a plastic material. A circular pressing member is fixed outside each group of the moving rods, an upper side and a lower side of each circular pressing member are inclined, and the circular pressing members are made of a plastic material. When discharging powder, the moving rods and the circular pressing members are controlled to move inside a storage member, so that caked powder is crushed and discharged smoothly, thereby to improve marking efficiency.
