[0024] The inner bottom surface of the lower shell body 2 is upwardly convexly provided with a hollow inner cylinder 21 with an open top surface. The lower part of the hollow cylinder 12 is movably extended into it and can move up and down along the hollow inner cylinder 21. The hollow inner cylinder 21 is used to guide the relative movement of the hollow cylinder 12 and the hollow inner cylinder. The left and right sides of the outer side walls of the hollow inner cylinder 21 are convexly provided with guide blocks 22 extending upward and higher than the hollow inner cylinder. The two guide blocks 22 are arranged opposite to each other, and the bottoms of the two guide blocks 22 extend to the inner bottom surface of the hollow inner cylinder 21. The opposite sides of the two guide blocks 22 are inclined surfaces, and the two inclined surfaces constitute a horn spacing that gradually expands from top to bottom, that is, the width of the inclined surface remains unchanged, and the inclined surface is inclined from bottom to top. The lower ends of the two inclined surfaces are between the upper ends of the two inclined surfaces. A through hole 44 is provided on the knife seat 4 for the upper end of the guide block 22 to pass through. The through hole 44 and the guide block 22 constitute the knife seat translation control structure. When in use, by utilizing the inclined surface of the guide block 22 , when the guide block 22 moves upward along the through hole 44 , the guide block 22 pushes the knife seat 4 to move inward.

[0025] A hollow guide column 23 is erected on the inner bottom surface of the lower shell 2 and is located outside the front and rear sides of the hollow inner cylinder 21. A guide rod 13 that can extend into the hollow guide column 23 extends downward from the bottom surface of the upper shell 1. A spring (not shown in the figure) is fixedly sleeved outside the guide rod 13. The outer diameter of the spring is larger than the inner hole diameter of the hollow guide column. The spring, the guide rod and the hollow guide column constitute the reset mechanism. When used, if the upper shell moves up and down relative to the lower shell or the lower shell moves up and down relative to the upper shell, the spring will be compressed, so that the relatively moving upper shell or lower shell has a reset restoring force, so that the upper shell or lower shell can be reset to its initial state.

[0026] The present invention discloses a portable article cutter, which can be used for cutting articles such as medicines and cigars. When the cut article (such as medicine) is shorter than the length of the hollow cylinder 12, the plugging head 3 is removed, the cut article is placed in the hollow cylinder 12, and then the plugging head 3 is covered to play the function of storing the article; if it is necessary to cut a section of the article in the hollow cylinder 12, the whole cutter is turned upside down, and the part of the cut article to be cut falls into the receiving cavity 31. The user can grasp the upper part of the plugging head 3 with his hand, and then press the lower shell 2 downward. The downward movement of the lower shell 2 causes the guide block 22 to pass through the knife seat 4 downward, and the two knife seats 4 are synchronously translated inward by using the inclined surface of the guide block 22. The translation of the two knife seats 4 causes the blade structure of the cutting blade 41 to extend into the notch 121, so that the cut article in the hollow cylinder 12 is cut left and right. 41 relative translation cutting, after cutting is completed, the plugging head 3 can be removed to take out the cut medicine, and the spring is compressed at the same time; when the cutting object (such as a cigar) is longer than the length of the hollow cylinder 12, the plugging head 3 is removed, and the cutting object is placed in the hollow cylinder 12, and the part to be cut extends out of the hollow cylinder 12. At this time, the upper shell 1 is pressed downward, and the upper shell 1 translates downward relative to the lower shell 2, while the guide block remains unchanged, and the knife seat 4 moves downward accordingly, the spring is compressed, and the knife seat 4 is affected by the inclined surface of the guide block during the downward movement and translates inward to achieve the cutting of the object. The lower shell 2 can also be pushed upward, and the upward movement of the lower shell 2 will also cause the two knife seats 4 to translate synchronously toward each other to achieve the cutting of the object; after cutting is completed, release the hand and the spring is reset. The reset of the spring will be affected by the inclined surface of the guide block and the knife seat will translate outward accordingly.

[0027] Compared with the prior art, the portable article cutter of the present invention can, on the one hand, seal and store articles and be used as a storage box; on the other hand, when an article is needed, the upper shell or the lower shell can be moved to cut out a small piece of the article, and cutting is convenient. When in use, the upper shell or the lower shell can be directly pressed hard so that the two cutters can quickly move toward each other. The cutting speed is fast and it is not easy to produce debris. You can cut as much as you need. It is very convenient to use, especially when cutting medicines, you can directly turn it upside down without taking it out and cutting it separately. It is more convenient to use, and the whole volume is small, easy to carry, and easy to process and manufacture.
