Abstract
The utility model relates to an unarmed slice cutting tool comprising a tool body. The unarmed slice cutting tool is characterized in that a blade part of the tool body is composed of two identical blades which are right-angle triangular prisms, an inclined plane of one right-angle triangular prism is opposite to that of the other right-angle triangular prism, and cutting edges of the two blades form two straight lines which are parallel to each other and located on the same plane; two opposite right-angle faces, of the right-angle triangular prisms formed by the two identical blades, are on the same level, namely 2mm-4mm in height. The two right-angle faces are mutually parallel and 0.05mm-0.15mm apart from each other. The unarmed slice cutting tool is simple in structure, convenient, fast, safe, low in cost, economical and practical and especially suitable for unarmed slice cutting experiments for junior high school students.
Description
Technical field
The utility model relates to a kind of Bioexperiment apparatus, especially in order to safety, the convenient and dedicated tool that carries out efficiently free-hand section.
Background technology
The free-hand section method shortcoming of mentioning in the biological textbook in junior middle school and some other documents is more, as: directly contact sharp razor blade with hand, be easy to injure experimenter self, also allow many students that the psychology of fear is arranged; Two blades clutching side by side with hand make just can cut out the interim section meeted the requirements after the alignment of blade lower edge, are difficult for holding, and conventional efficient is not high yet.
Summary of the invention
For dangerous, the trouble and the inefficient deficiency that effectively overcome that original free-hand section device exists, the utility model provides a kind of free-hand section cutter, and this free-hand section cutter can make free-hand slicing experiment be able to safer, convenient and carry out efficiently.
The utility model solves the technical scheme that its technical problem adopts: it comprises cutter hub, it is characterized in that: the blade of cutter hub consists of two identical blades, two blades are rectangular triangular prism all, and the inclined-plane of the inclined-plane of a right-angle prismatic post and another right-angle prismatic post is opposing; The cutting edge of described two blades all is straight line, two straight line parallels and in the same plane of this presenting.The right-angle prismatic post that described two identical blades present, the height of two right angle faces that it is relative is 2mm-4mm, and highly identical; These two right angle faces are parallel to each other, and both are at a distance of 0.05mm-0.15mm.
The beneficial effects of the utility model are, simple in structure, and Portable safety is cheap, economical and practical, is particularly suited for the junior school student and carries out the free-hand section experiment, are easy to promote.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is left view of the present utility model.
Fig. 2 is structural representation of the present utility model.
1. cutter hubs in figure, 2. blade, the inclined-plane of the right-angle prismatic post that 3. blade presents, the right angle face of the right-angle prismatic post that 4. blade presents, 5. cutting edge.
The specific embodiment
In Fig. 1, the utility model consists of cutter hub (1).The blade of cutter hub (1) consists of two identical blades (2), two blades (2) are rectangular triangular prism all, and the inclined-plane (3) of the right-angle prismatic post that presents of the inclined-plane (3) of the right-angle prismatic post that presents of one of them blade and another blade is opposing; The cutting edge (5) of described two blades (2) all is straight line, two straight line parallels and in the same plane of this presenting.The right angle face (4) of the right-angle prismatic post that one of them blade presents, the relative arrangement of right angle face (4) of the right-angle prismatic post presented with another blade, parallel to each other, both are at a distance of 0.05mm-0.15mm.The height of these two right angle faces is 2mm-4mm, and highly identical.In Fig. 2, the blade of visible cutter hub of the present utility model (1) consists of two identical blades (2), and the cutting edge (5) of two blades (2) all is straight line.The user clamps the above part of blade (2) of cutter hub of the present utility model (1) with finger, the object that fly-cutting is cut, produce thin and transparent satisfactory interim section in the space between two blades (2); Again the utility model is placed in to clear water and can obtains required interim section.
Claims (2)
1. a free-hand section cutter, comprise cutter hub, it is characterized in that: the blade of cutter hub consists of two identical blades, and two blades are rectangular triangular prism all, and the inclined-plane of the inclined-plane of a right-angle prismatic post and another right-angle prismatic post is opposing; The cutting edge of described two blades all is straight line, two straight line parallels and in the same plane of this presenting.
2. free-hand section cutter according to claim 1 is characterized in that: the right-angle prismatic post that described two identical blades present, and the height of two right angle faces that it is relative is 2mm-4mm, and highly identical; These two right angle faces are parallel to each other, and both are at a distance of 0.05mm-0.15mm.
