    • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • Referring to the drawings, and initially to FIGS. [0024] 1-5, a sheet material cutting device in accordance with the present invention comprises a base 21 including a soft or resilient strap 23 secured on top thereof, and comprises two brackets 26 disposed thereon and preferably separated from each other and disposed on the end thereof. Two arms 32 each has one end pivotally secured to the brackets 26 with a pivot axle 28. A guide track 31 is secured between the arms 32, and preferably secured between the other ends of the arms 32, such that the track 31 may be rotated relative to the base 21 about the pivot axles 28.
  • A [0025] seat 30 includes a protrusion 301 (FIGS. 5, 6) extended therefrom and slidably engaged in the track 31 for guiding the seat 30 to move along the track 31. A cutter blade, such as a circular cutter blade 33 is rotatably secured to the seat 30 with a fastener or a pivot pin 303. A cover 304 is secured to the seat 30 for shielding the cutter blade 33. The seat 30 may be moved along the track 31 (FIGS. 7, 8), and may be moved away from and toward the base 21 by rotating the track 31 about the pivot axles 28 (FIGS. 5, 6) in order to cut the sheet materials 80 (FIG. 5) that is provided on the base 21. An inverted U-shaped cap 307 is secured on top of the seat 30 for allowing the cutter blade 33 to be forced to cut the sheet materials 80.
  • The sheet material cutting device further includes a [0026] board 34 having a depression 35 formed therein for receiving the base 21, and having one or more cavities 50 formed therein and communicating with the depression 35 thereof. The base 21 includes one or more projections 44 extended forward or sidewise therefrom for engaging into the cavities 50 of the board 34 and for detachably securing to the board 34 with a force-fitting engagement, for example. The base 21 includes an upper surface flush with the upper surface of the board 34 such that the surface of the cutting device for supporting the sheet materials may be increased or enlarged or extended.
  • The sheet material cutting device further includes a [0027] plate 37 having one or more ears 38 extended therefrom for engaging into the end portion 36 of the board 34 and for securing to the board 34 with fasteners 39. The upper surfaces of the board 34 and of the plate 37 are flush with each other such that the surface of the cutting device for supporting the sheet materials may further be increased or enlarged or extended.
  • Referring next to FIG. 9 and again to FIGS. [0028] 1-4, the base 21 includes an opening or a guide channel 24 formed in the front and bottom portion thereof. A drawer 40 is slidably received in the guide channel 24 of the base 21 and includes one or more retainers 41 provided therein for engaging with the center holes 42 of the cutter blades 34 and for retaining one or more spare cutter blades 33 in the drawer 40. A pincer 43 is further provided and received in the drawer 40 for fetching the cutter blade 33 (FIG. 9) and for allowing the cutter blades 33 to be easily disengaged from the drawer 40 and to be easily attached onto the seat 30.
  • Accordingly, the sheet material cutting device in accordance with the present invention includes a base that may be adjusted to different areas, and includes one or more cutter blades that may be easily changed or replaced with each other. [0029]
  • Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made by way of example only and that numerous changes in the detailed construction and the combination and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as hereinafter claimed. [0030]
