Detailed Description

The technical solution of the present invention is described in further detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the following description.

As shown in fig. 1 to 4, a portable paper cutter includes a cutter holder 1, a paper pressing frame 2 and a blade holder 3.

A through chute is arranged downwards from the top of the knife rest 1, the blade fixing frame 3 is arranged in the chute in a sliding way, and the bottom of the blade fixing frame 3 is connected with a blade 5. The paper pressing frame 2 is fixedly connected with one side of the knife rest 1, the bottom surface of the paper pressing frame 2 is flush with the bottom surface of the knife rest 1, and a notch is formed in the bottom surface of the paper pressing frame 2. Still include scale 4, the one end of scale 4 and the rotatable connection of paper pressing frame 2, scale 4 can be accomodate in the breach. When the device is carried, the scale 4 can be accommodated in the notch, and the whole device is small and exquisite and has good portability. When in use, the whole device is placed on paper, the bottom surface of the paper pressing frame 2 and the bottom surface of the knife rest 1 are used for pressing the paper, the blade fixing frame 3 is slid, and the blade 5 is used for cutting the edge of the paper; then the scale 4 is rotated out, the whole device is moved directly according to the scale of the scale 4 and the size to be cut, then the paper is pressed, and the cutting can be finished by reversely sliding the blade fixing frame 3. When the paper cutter cuts, paper is pressed flat by the bottom surfaces of the paper pressing frame 2 and the cutter frame 1, so that the paper can be kept stable, does not wrinkle, does not move or deform in the cutting process, and the cutting quality is good; meanwhile, the cutting size is directly controlled by the scale 4 when the paper knife is used, the cutting precision is high, the paper knife is not limited to the cutting of the specific specification of the traditional plate-type paper knife, the application range is wide, and the operation is convenient.

Further, the knife rest 1 comprises a frame body, the two ends of the frame body are connected with knife rest seats 11, the bottom surfaces of the knife rest seats 11 are lower than the bottom surface of the frame body, the sliding grooves are formed in the frame body, and the bottom surface of the paper pressing frame 2 is flush with the bottom surface of the knife rest seats 11. Through the arrangement, in the cutting process that the paper is pressed tightly by the bottom surface of the paper pressing frame 2 and the bottom surface of the knife rest seat 11, a certain paper avoiding space exists around the blade 5, the stability of the paper during cutting is further ensured, and the cutting precision is ensured.

Further, the bottom surface of scale 4 flushes with the bottom surface of pressing paper holder 2, and when cutting, the bottom surface of scale 4 also compresses tightly the contact with the paper top surface, and on the one hand, it is bigger to the area that compresses tightly of paper, and the cutting process is more stable, and on the other hand the paper makes the friction exist between the two to the reaction force of scale 4, can not swing at will at the in-process scale 4 that cuts, ensures to cut the accuracy.

Further, the blade holder 3 includes a slider 31, a pressing block 32, and a return spring 33. The sliding seat 31 is slidably disposed in the sliding groove, the top of the sliding seat 31 is open, one end of the pressing block 32 is slidably disposed in the sliding seat 31, two ends of the return spring 33 are respectively connected to the pressing block 32 and the sliding seat 31, the extending and retracting direction of the return spring 33 is the same as the sliding direction of the pressing block 32 in the sliding seat 31, and one end of the blade 5 far from the cutting edge thereof penetrates through the bottom surface of the sliding seat 31 and is connected with one end of the pressing block 32. When the cutting is needed, the blade 5 can be pushed out for cutting by manually pressing the pressing block 32; when the cutting is not needed, the pressing block 32 is loosened, the pressing block 32 is jacked up under the action of the return spring 33, and the blade 5 is collected into the blade fixing frame, so that the safety is ensured.

Furthermore, the paper pressing frames 2 are two in number, the two paper pressing frames 2 are fixedly connected with two sides of the knife rest 1 respectively, the two paper pressing frames 2 are arranged in a central symmetry mode, a user can use the paper cutter partially in the front-back direction, and the operation is very convenient.

In specific implementation, the knife rest 1 is made of an aluminum alloy material, so that the attractiveness of the product and the strength and rigidity of the product in the using process are both considered, and the product is prevented from deforming due to pressure applied by hands in the using process; the blade 5 is made of high-quality alloy steel, finished products can be purchased directly from the market, the cost is controllable, the blade 5 is clamped in the pressing block 32 and is retracted when not used, and accidental injury to a human body in the carrying process is avoided; the paper pressing frame 2 is made of plastic materials, so that the attractiveness and the cost of the product are both considered, and the paper pressing frame is assembled with the knife rest 1 through the buckle, so that the assembly process is simple and convenient, and the assembly reliability of the product is ensured; reset spring 33 adopts musical instrument steel wire preparation to form, can repeatedly press more than 10000 times, durable.

The foregoing is illustrative of the preferred embodiments of the present invention, and it is to be understood that the invention is not limited to the precise forms disclosed herein, and that various other combinations, modifications, and environments may be resorted to, falling within the scope of the invention as defined by the appended claims.
