Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to cigar cutters, and in particular to a cigar cutter which has two blades at two sides. The blades can move inwards to a fixed position and to cut a cigar and moreover, the two blades is movable outwards by an easy operation with slightly force applied thereto so that a cigar can be inserted into a hole in the cigar cutter for being cut. 
       BACKGROUND OF THE INVENTION 
       [0002]    Many cigar cutters exist in which one or two blades push through a cigar. Such cutters can be appropriately called guillotine or double-guillotine cutters. These types of cutters suffer from the deficiency that they can crush, squash, or otherwise deform the cigar as they cut it. They can also tear the wrapper leaf or the endcap of the cigar as the blades are forced through the cigar. 
         [0003]    In one prior art a cigar cutter, the cigar cuter comprises a frame with a slot and a hole therethrough, said frame having two sides which are parallel to each other, said frame being teardrop shaped, which slot has a rectangular cross section, and which hole is perpendicular to the slot and is sized to accommodate a cigar tip; and two blades, each blade with a hinge end and a cutter end, said cutter end having two edges, the first of which said edges is sharp and the second of which is dull, said blades hingeably coupled with each other and said frame and operably mounted so that said blades slide through the slot in said frame and effectuate movement of first edges of said cutter ends of said blades across each other scissors-like, said blades crossing at the hole in said frame. 
         [0004]    Furthermore, in another type of cigar cutter exists in which a part of the cigar cutter can be pivotally displaced with respect to another part of the cigar cutter. In the course of this pivoting movement, the cutter&#39;s blades are subjected to a rotational movement corresponding to the pivoting movement and concurrently to a translational movement, thus progressively effecting the cutting of the cigar. In the alternative, the cigar cutter includes a lever that is turnable. By pivoting the lever, the cutter&#39;s blades are moved circularly in a hypocycloidal path. Both embodiments produce a peripheral cutting action at the same time that the blades penetrate into the cigar. 
         [0005]    In view of the art, a need exists for a cigar cutter in which the application of a squeezing force causes the cutter&#39;s blades to cut a cigar in a manner intended to avoid substantial deformation and tearing of the cigar. 
       SUMMARY OF THE INVENTION 
       [0006]    Accordingly, the primary object of the present invention is to provide a cigar cutter, which has two blades at two sides. The blades can move inwards to a fixed position and to cut a cigar and moreover, the two blades is movable outwards by an easy operation with slightly force applied thereto so that a cigar can be inserted into a hole in the cigar cutter for being cut. 
         [0007]    To achieve above objects, the present invention provides a cigar cutter mainly formed by a bottom sheet, a left blade, a right blade and an upper sheet. The four sheets are locked by a stud, while the left and right blade are movable with respective to the bottom sheet. The centers of these sheets have holes which are aligned. When a cigar passes through the hole, the two blades can move inwards to cut the cigar. A skilled design mechanism is formed in the four sheets so that as the two blades can be received within the two blades in a storage state. When it is desired to insert a cigar into the holes of the sheets, the two blades can be compressed inwards, and than the blades will resilient outwards by resilient forces of springs. 
         [0008]    The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.

A lower side of the right blade  40  is formed with a hook  46 ; a soft locking block  47  is attached to the hook for locking to the nose  37  in the recess  36  of the operation bar  32  of the left blade  30 . A notch  48  is formed at a left side of the body  41  of the right blade  40  and is above the half round cutting edge  44  of the body  41  of the right blade  40 . The soft locking block  47  is formed by a first block  471  and a second block  472  assembled to the first block  471  which is movably assembled to the first block  471 . The first block  471  is hooked to the hook  46  of the right blade  40 . 
         [0027]    A restore spring  50  is installed between a wall of the notch  48  of the right blade  40  and a wall of the notch  38  of the left blade  30 . 
         [0028]    Referring to  FIGS. 3 and 4 , in assembly, a stud  60  serves to lock the bottom sheet  10 , the left blade  30 , the right blade  40  and the upper sheet  20  sequentially by passing through the lock hole  14  of the bottom sheet  40 , the locking hole  39  of the left locking ear  33  of the left blade  30 ; the locking hole  49  of the right locking ear  43  of the right blade  40 ; and the locking hole  24  of the upper sheet  20  sequentially; the round hole  11  of the bottom sheet  10  is aligned to the round hole  21  of the upper sheet  20 ; the left blade  30  and right blade  40  are rotatable with respect to the stud  60 . The restore spring  50  is installed between a wall of the notch  48  of the right blade  40  and a wall of the notch  39  of the left blade  30 . A perspective view of the assembled cigar cutter according to the first embodiment of the present invention is illustrated in  FIG. 2 . 
         [0029]    The operation of the present invention will be described herein. Referring to  FIGS. 3 ,  4 ,  5 , and  6 , as the left blade  30  and right blade  40  move inwards to be within a space formed between the bottom sheet  10  and the upper sheet  20 . To an extreme position, the soft locking block  47  will enter into the recess  36  of the left blade  30  to be buckled by the nose  37  in the recess  36 . Then the two blades  30 ,  40  are retained in a buckling state. As illustrated in  FIG. 3 , the cigar cutter of the present invention is formed as a rectangular shape. At this moment, the spring  50  is at a compressed state. The half round cutting edge  44  of the right blade  40  and the half round cutting edge  34  of the left blade  30  will combined with as a hole with a size smaller than that of the round hole  21 ,  11  of the bottom sheet  10  or the upper sheet  20  so as to cut a cigar (not shown) passing through the round holes. When a further compressing force is applied to the left blade  30  and the right blade  40 , the two blades are compressed further, while the spring  50  will suffer from a greater compressing force. When the compressed force applied to the two blades  30 ,  40  is released, the spring  50  will apply a resilient force to the two blades  30 ,  40  to make the two blades  30 ,  40  move outwards. Since the soft locking block  47  is soft, the soft locking block  47  deforms and easily unbuckled from the nose  37  in the recess  36 .

The second spring  900  is installed between a left edge of the through hole  701  of the pad sheet  700  and a right edge of the right elastic sheet  803  so as to retain the right elastic sheet  803  to the pad sheet. A perspective view of the assembled cigar cutter according to the first embodiment of the present invention is illustrated in  FIG. 8 . 
         [0043]    Operation of this embodiment will be described herein. Referring to  FIGS. 9 ,  10 ,  11  and  12 , as the left blade  300  and right blade  400  move inwards to be within a space formed between the bottom sheet  10  and the upper sheet  20 ; to an extreme position, the protrusion of the left elastic sheet  801  will buckle the recessed notch  407  at the lower edge of the left blade  400  so as to retain the left elastic sheet  801  in position. The left elastic sheet  400  will retain the right elastic sheet  500  in position. As illustrated in  FIG. 4 , the cigar cutter of the present invention is formed as an oblong shape. At this moment, the restore spring  600  and the second spring  900  are at a compressed state. The half round cutting edge  404  of the right blade  400  and the half round cutting edge  504  of the left blade  500  will overlap to seal the round hole  201   101  of the bottom sheet  100  or the upper sheet  200  so as to cut a cigar (not shown) passing through the round holes. When a further compressing force is applied to the left blade  300  and the right blade  500 , the two blades are compressed further, while the spring  500  will suffer from a greater compressing force. When the compressed force applied to the two blades  300 ,  500  is released, the restore spring  600  will apply a resilient force to the two blades  300 ,  500  to make the two blades  300 ,  500  move outwards. Since left elastic sheet  801  is made of soft material, the protrusion of the left elastic sheet  801  will unbuckle from the recessed notch  407  at the lower edge of the left blade  400 . Thereby, the cigar cutter is at a releasing state as illustrated in  FIG. 11  and  FIG. 12 . The operation is very easy and only a slight force is needed for unbuckling operation due to the installation of the spring. 
         [0044]    The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
