1. Field of the Invention
The present invention relates generally to a paper cutting device, and more particularly to a paper cutting device, which provides various patterns of cutting.
2. Description of the Related Art
A conventional paper cutting device is put on a table or desk to cut papers, which has a base with a rail and a cutter assembly slidably mounted on the rail of the base. The cutter assembly has a cutter and is reciprocated along the rail to cut the paper on the base. Such paper cutting device has a simple structure and single function that is broadly applied to user because of its convenience.
The primary objective of the present invention is to provide a cutter assembly of a paper cutting device, which have various cutting patterns for choice as well as simple structure and easy operation.
According to the objective of the present invention, a cutter assembly of a paper cutting device comprises a housing having a chamber therein. A base is fixed at a bottom of the housing, which has a first slot and a second slot, and both of the slots are communicated with the chamber of the housing. A first cutter is received in the first slot of the base to be moved between an extruding position and a storage position. A second cutter is received in the second slot of the base to be moved between an extruding position and a storage position. A switch is received in the chamber of the housing to cover the first cutter and the second cutter. The switch is moved between the a first position, in which the switch moves the first cutter to the extruding position from the storage position, and a second position, in which the switch moves the second cutter to the extruding position from the storage position.

The housing 20 has a chamber 21 therein, which is open at a bottom thereof and has a hole 22 at a top thereof.
The base 30 has a body portion 31 to be received in the guiding slot 121 of the rail 12. The body portion 31 has two upper flanges 32 and two lower flanges 33 at opposite lateral sides thereof. The flanges 31 and 32 are located above and below the rail 12 (referring to
The first cutter 40 has a mount 41 and a cutter 42, wherein the mount 41 is received in the first slot 311 of the base 30 to slide along the first slot 311. The mount 41 has an inclined resting face 411 at a top thereof. The cutter 42 is mounted at a bottom of the mount 41 with a blade 421 thereof extruded out of the base 30 via the first aperture 315.
The second cutter 50 has a mount 51 and a rolling cutter 52, wherein the mount 51 is received in the second slot 313 of the base 30 to slide along the second slot 313. The mount 51 is a U-shaped element having a recess 511 at a top thereof and two inclined resting faces 512 at the top thereof and at opposite sides of the recess 511. The inclined directions of the resting faces 512 is opposite to the resting face 411 of the first cutter 40. The rolling cutter 52 is received in the recess 511 of the mount 51 and pivoted on the mount 51 with a portion thereof beyond the mount 51 and passing through the second aperture 314 of the base 30. The rolling cutter 52 has a waved blade 521 at a periphery thereof.
The first elastic member 60, which is a compression spring in the present invention, have opposite ends fitted to the cutter 42 of the first cutter 40 and rested on the mount 41 respectively to move the first cutter 40 upward to a storage position (referring to
The second elastic member 70 has two elastic plates 71 and 72, each of which has opposite ends mounted on the bottom of the mount 51 and rested on the a sidewall of the second slot 313 of the base 30 to move the mount 51 to a storage position (referring to
As shown in
In operation, user has to exert the post 81 to move the switch 80 and to switch the first cutter 40 and second cutter 50 for cutting. When the first cutter 40 is chosen, it cuts the paper with a straight edge, and when the second cutter 50 is chosen, it cuts the paper with a waved edge.
In conclusion, the paper cutting device of the present invention is very convenient to be put on a table for cutting papers. It also can switch various cutters to cut papers, such that it gets various cutting patterns. The rail is made of flexible plastic that the rail is pressed at opposite sides thereof to deform the guiding slot and to assemble and disassemble the base of the cutter assembly.
It has to be mentioned here that the first and second elastic members are to return the cutters, such that any element, such as spring, elastic plate, flexible rubber, serving the same function is the equipollent device.
