Field of the Invention
The present invention relates to a device for cutting a medicine tablet, and more particularly to device for cutting a medicine tablet into halves or quarters.
Description of the Prior Art
A device for cutting a medicine tablet includes an inclined medicine-placing platform and a cutting blade pivoted to each other. When a medicine tablet to be cut is placed on the inclined medicine-placing platform, the cutting blade cuts downward, and the medicine tablet to be cut is cut into halves. This type of devices for cutting a medicine tablet are disclosed in TW175018 and TWM381400.
However, in this type of prior arts, the medicine tablet cannot be cut into quarters. If a user wants to cut the medicine tablet into quarters, the user needs to rotate the medicine tablet to another angle by hand and repeat the cutting motion again. In addition, the medicine tablet which is cut into halves cannot be positioned firmly so that the cutting blade cannot cut the halves of the medicine tablet again precisely.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
The major object of the present invention is to provide a device for cutting a medicine tablet, wherein a user can choose to cut the medicine tablet into halves or quarters once.
To achieve the above and other objects, a device for cutting a medicine tablet is provided, including a base, a cutting device and a carrying plate. The base extends along an axis. The cutting device has a fixed cutter and a movable cutter base, the fixed cutter is fixedly disposed inside the base, the movable cutter base optionally positionably moves between a protruding position and a retreating position axially, the movable cutter base has a movable cutter, when the movable cutter base is in the protruding position, a blade of the movable cutter is near a blade of the fixed cutter, and when the movable cutter base is in the retreating position, the blade of the movable cutter is remote from the blade of the fixed cutter. The carrying plate is for being operated and movably disposed inside the base, the carrying plate has a carrying face for carrying a medicine tablet, and the carrying face faces the blade of the fixed cutter and is able to approach the blade of the fixed cutter optionally.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment(s) in accordance with the present invention.
