[0008] In accordance with one aspect of the invention, there is
provided a sheet material cutting device comprising a base for
supporting sheet materials to be cut, the base including two
brackets disposed thereon, two arms each including a first end
pivotally secured to the bracket with a pivot axle, a track secured
between the arms and rotated in concert with the arms relative to
the brackets, a seat slidably engaged on the track and movable
along the track, and a cutter blade secured to the seat and
forcible toward the base to cut the sheet materials. The cutter
blade may be forced toward the base in order to forcefully and
effectively cut the sheet materials.
[0009] The seat includes a protrusion slidably engaged into the
track for slidably securing and for guiding the seat to slide along
the track.
[0010] A board is further provided and includes a depression formed
therein for receiving the base, the base and the board have an
upper surface flush with each other for supporting the sheet
materials.
[0011] The board includes at least one cavity formed therein, the
base includes at least one projection extended therefrom and
engaged into the cavity of the board for detachably securing the
base to the board.
[0012] A plate is further provided and includes at least one ear
secured to the board, the plate and the board have an upper surface
flush with each other for supporting the sheet materials.
[0013] The base includes a guide channel formed therein, and
includes a drawer slidably received in the guide channel of the
base. One or more spare cutter blades are further provided and
secured in the drawer.
[0014] The drawer includes at least one retainer disposed therein
for retaining the spare cutter blade in the drawer. A pincer is
further provided and secured in the drawer for fetching the cutter
blades.
[0015] Further objectives and advantages of the present invention
will become apparent from a careful reading of a detailed
description provided hereinbelow, with appropriate reference to
accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
[0024] Referring to the drawings, and initially to FIGS. 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.
[0025] A 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.
[0026] The sheet material cutting device further includes a 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.
[0027] The sheet material cutting device further includes a 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.
[0028] Referring next to FIG. 9 and again to FIGS. 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.
[0029] 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.
[0030] 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.
