Title: Screw strip with flanges at two sides

Description:
FIELD OF THE INVENTION  
       [0001] The present invention relates to screw strips, and particularly to a screw strip with flanges at two sides. By the flanges, when the screw strip passes through the transfer guide groove of a nail gun, it can be positioned so as to prevent the screw strip bends and deforms as the screws passes through the strip.  
       BACKGROUND OF THE INVENTION  
       [0002] Nail guns are used to inject screws. Referring to FIGS.  1  to  4 , a prior art screw strip  10  is a long strip injected from a plastic material. The screw strip  10  has a plurality of receiving holes  11  for receiving a plurality of screws  20 .  
       [0003] An outer side of each receiving hole  11  has a plurality of radiated long slits  12 . Two sides of the screw strip  10  have a plurality of slots  13  for pushing a nail gun  30  therethrough (referring to FIG. 1). The screw strip  40  is placed to pass through the transfer guide groove  31  of the nail gun  30  for transferring screws automatically (referring to FIGS. 2 and 3). Thereby, the screw strip  40  has the function of transferring screws  20 . However, the prior art screw strip  10  is a thin piece (referring to FIG. 3). When the prior art screw strip  10  is placed in the transfer guide groove  31  of the nail gun  30 , if the screw  20  damages the screw strip  10 , the screw strip  40  will bend forwards (referring to FIG. 4) so that two sides of the screw strip  10  are separated from the transfer guide groove  31  of the nail gun  30 . As a result, the screw strip is buckled in the transfer guide groove and thus can not be used continuously.  
       SUMMARY OF THE INVENTION  
       [0004] Accordingly, the primary object of the present invention is to provide a screw strip which is a long strip and has a plurality of receiving holes for receiving a plurality of screws. A periphery of each receiving hole has a plurality of radiated long slits. Two sides of the screw strip have a plurality of slots for pushing a nail gun therethrough. Each of two sides of the screw strip has a plurality of flanges which is matched to the transfer guide groove of a nail gun. By the flanges, when the screw strip passes through the transfer guide groove of a nail gun, it can be positioned so as to prevent the screw strip bends and deforms as the screws pass through the strip.  
       [0005] 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.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
     [0015] Referring to FIG. 5, the perspective view of the screw strip  40  according to the present invention is illustrated. In the present invention, the screw strip  40  is a long strip injected from a plastic material. The screw strip  40  has a plurality of receiving holes  41  for receiving a plurality of screws  50 .  
     [0016] An outer side of each receiving hole  41  has a plurality of radiated long slits  42 . Two sides of the screw strip  40  have a plurality of slots  43  for pushing a nail gun  60  therethrough. Each of two sides of the screw strip  40  has flanges  44  so that viewing from the lateral sides, the screw strip  40  is illustrated as a T shape (referring to FIGS. 6 and 7) or an L shape (referring to FIG. 8). A cross section of the flange  44  can be a rectangular shape (referring to FIG. 7) or a round shape (referring to FIG. 9) or other shapes. Thereby, by the flanges  44 , when the screw strip  40  passes through the transfer guide groove  61  of a nail gun  60 , it can be positioned so as to prevent the screw strip  40  bends and deforms as the screws  50  passes through the strip.  
     [0017] It is appreciated from above description that in the present invention, the two sides of the screw strip  40  are installed with a plurality of flanges  44 , and the transfer guide groove  61  of the nail gun  60  are made to match the flanges  44 . When the screw strip  40  passes through the transfer guide groove  61  of a nail gun  60 , it can be positioned so as to prevent the screw strip  40  bends and deforms as the screws  50  passes through the strip. Thereby, the user can operate easily.  
     [0018] 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.
