  • Patent number: 11406566
    Abstract: A pill cutter has a base, a clamping assembly, a connecting unit, a cover, and a cutting assembly. The clamping assembly has two first clamping units moveably mounted on the base. The connecting unit has a base end moveably mounted on the base and a cover end pivotally mounted on the cover. The cutting assembly has a pressing unit moveably mounted on the cover and a blade securely mounted on the pressing unit. When the cover is opened, the connecting unit moves along with the cover and pulls the two first clamping units away from each other. When the cover is closed, the two first clamping units move toward each other by springs to stably clamp a pill in any shape or size. Therefore, a user can simply press the pressing unit to move the blade to safely cut the clamped pill.
