BACKGROUND OF THE INVENTION
Generally, secretaries and graphic designers often need to use tools to cut paper, film, cellophane paper or plastic sheets. The most frequently used cutting tools are scissors, rulers, and cutters, but they are limited to few cuttings. For frequent users or for cuttings other than straight cuttings, such as cuttings in wave or sewing form, a cutting machine is more convenient and efficient.
The above-mentioned conventional cutting machine refers to a guillotine-type cutting machine. Such cutting machine has evolved to have multiple functions. For example, a paper trimmer that has a guillotine type blade and a rotary trimmer integrally formed. However, whether it is a single function cutting machine or a two-in-one cutting machine, there still exist many disadvantages, such as the structure is complex, the assembly thereof is troublesome, and the cutting is not practical.
The inventor has many years of experience in developing and manufacturing such products. After years of improvement, the present invention is finally reduced to practice. The design of the present invention is to provide a single-axle blade and a ruler on one side of the cutting machine, while a rotary blade is provided on the other side. The rotary blade base and the rotary frame can rotate vertically or horizontally, and the rotary lever and the rotary blade are characterized in an easily assembled structure.
SUMMARY OF THE INVENTION
The present invention provides an improved cutting machine. A cutter and a ruler are provided on one side of the cutting board, while a rotary blade is provided on another side. The rotary blade and the rotary frame can rotate vertically or horizontally, and the rotary lever and the rotary blade are characterized in an easily assembled structure.

DESCRIPTION OF THE EMBODIMENTS
Refer to FIG. 1. The improved cutting machine of the present invention includes a cutting board 1, a straight cutter base 2, a cutter 3, a ruler 4, a rotary frame 5, a rotary blade base 6, and a cutting pad 7.
One side of the cutting board 1 is screwed with a straight cutter base 2, and the same side of the cutting board 1 is provided with a protrusion 11 so as to allow a cutter 3 to be screwed on the side of the cutting board, and to form a cross-sectional cutting plane with the straight cutter base 2. As shown in FIG. 9, a screwing cap used to screw the cutter 3 is a gel cap 31 having a gel layer 311 added to the internal screw so that after a screw 32 is screwed into the gel cap 31, it will not be loosened or shifted. The cap further has a disc-typed spring gasket 33, so that when the cutter 3 is screwed, an appropriate tension is formed to enhance the cutting effect. In addition, the cutting board 1 is provided with a pad 12 on the side corresponding to the cutter 3, so that when the cutter 3 is pushed to the bottom, buffer is provided to prevent noise.
Refer to FIG. 3. The cutter 3 of the present invention is appropriately curved (as shown by the vertical distance D1 in the figure). It is accompanied by the appropriate tension mentioned above to obtain better cutting.
Furthermore, the inner side of the straight cutter base 2 on the cutting board 1 is provided with an engaging hole 13 on the front end and the back end respectively, so as to provide a flange 41 on the two sides of a ruler 4 to be placed into the engaging hole 13 to position the ruler 4. As shown in FIG. 6, the ruler 4 is designed to be curved in the middle (as shown by the vertical distance D2 in the figure). The curve is designed such that after the ruler 4 is positioned, a horizontal plane of the cutting board 3 is presented with an appropriate gap with the ruler 4 to facilitate easy placement of a cutting item, such as paper, into a cutting position.
Refer to FIG. 2. An appropriate place on one side of the cutting board is provided with a containing groove 14 and a cover thereof 141 so as to allow a variety of rotary blades or small stationery to be placed therein. Another side of the cutting board 1 is provided with a pair of corresponding axle-supporting bases 15. An axle-supporting hole 151 is in the center of the axle-supporting base 15. The top of the axle-supporting base 15 is provided with a protrusion 152, so as to position the rotary frame 5 when it is rotated to a vertical position.
Refer to FIG. 2. A rotary frame 5 has a rolling rail 51 in the center portion. The bottom of the rolling rail 51 is stuck with a stopping pad 511. The two sides of the rolling rail 51 are provided with a pair of corresponding rotary bases 52 to correspond to the axle-supporting base 15. The assembly of the rotary base 52 and the axle-supporting base 15 is an engagement of a corresponding bearing cylinder 53 and an engaging piece 54.
Refer to FIG. 7. A rotary blade base 6 can be inserted into the rolling rail 51. The rotary blade base 6 downwardly provides an elastic piece 61 such that when it is placed into the rolling rail 51, an upward tension is formed. One side of the rotary blade base 6 is provided with an axle hole 62, allowing a variety of rolling cutters 63 in straight line, wave, sewing forms to be engaged with an engaging cover 65 after an axle 64 is inserted. The engagement is performed by providing a flange 66 on one side of the rotary blade base 6 to accommodate the engaging block 651 on the inner side of the engaging cover 65, and thus it is securely fastened with each other respectively so as to provide easy placement of the rotary blade 63.
Refer to FIG. 8. The above-mentioned rotary frame 5 along with the rotary blade base 6 thereon can be presented horizontally to the cutting item or be vertically rotated to facilitate cutting operation.
As shown in FIG. 4, the cutting board 1 is provided with an engaging groove 16 at a place corresponding to the rotary blade 63 on the rotary blade base 6 so as to place a cutting pad 7 therein. The two sides of the engaging groove 16 are provided with protrusions 161 alternatively on the two sides, so as to allow easy placement of the cutting pad 7 as well as to ensure positioning. Furthermore, a pair of corresponding elastic pieces 17 are provided on the two sides of the engaging groove 16 on the cutting board 1 so as to maintain an appropriate gap with the cutting item when the rotary blade base 6 is horizontal in relation to the cutting item to facilitate easy placement of the cutting item, such as paper, into the cutting position.
In summary, the present invention provides a cutting machine with a simply structure, easy operation, and great cutting effect.
