Title: Nail guider and nailing device having the same

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to the field of a nail guider and a nailing device having the same 
     2. Description of the Prior Art 
     Conventional nailing devices use a striking board for striking nails so that the nail could be nailed into a target. Among conventional nailing devices, some of them would be disposed with a nail guider in front of a nail track so that the nail would be hit out vertically or the nail would not stock the nail track because of being crooked. As such, the nail can keep standing vertically before being hit out with the help of the nail guider. 
     As the patent U.S. Pat. No. 5,692,665 mentioned, a nail guider is disclosed. In the FIG. 1 of the patent, the two guiding feet 8, 9 can use elasticity for pivoting to the front of the nail track selectively. Thus, the nail is straightened up. Besides, as shown in FIG. 3, the composition method of the two guiding feet 52, 62 is replaced by using a fulcrum 33. Also, the nail guider uses the elastic slice 70 for abutting and pushing the two guiding feet 52, 62 so that the two guiding feet 52, 62 would pivot toward a direction of the nail track. 
     In other words, the guiding feet of the conventional nail guiders is designed to pivot. The disadvantage of the design is that the guiding feet would be tilting when straightening the nail up. As a result, a lateral side of the nail could not be completely straightened up, and a force could not distribute on the nail evenly as well. Thus, the function of the nail guider would be influenced. 
     SUMMARY OF THE INVENTION 
     The main object of the present invention is to provide a nail guider capable of straightening lateral sides of nails completely. 
     To achieve the above, the present invention provides a nail guider to be disposed in a nailing device, and the nailing device comprises a nail track. The nail guider is disposed in front of the nail track. The nail guider comprises a guiding board, at least an assisting member and a pushing means. The guiding board, positioned in front of the nail track vertically, has a first surface and a second surface, and the first surface is opposite to the second surface. The first surface faces the nail track, and the guiding board  10  has at least a vertical penetrating slot thereon. 
     The penetrating slot penetrates the first surface and the second surface of the guiding board. The assisting member can slide forwardly and backwardly in the penetrating slot, and the assisting member has an assisting end and a pushing end. The assisting end protrudes out of the first surface selectively, and the pushing end is located at the second surface. The assisting member further comprises at least an assisting surface parallel to the nailing track. In other words, the assisting surface is located at two sides of the assisting end, and the assisting surface is used for straightening up nails. As such, the assisting end has a tendency of protruding out of the first surface. 
     In conclusion, speaking of a former disadvantage that nail guiders with pivoting design disables nails to be supported with even force, so a feature that the assisting member can straightly slide along a horizontal direction improves the former disadvantage. Thus, the assisting member keeps straightening the nail up in a vertical moving process of the striking board, so the nails would not be crooked or stocked when being stroke by the striking board. The working efficiency of the nailing device is enhanced as well. 
     The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purpose of illustrations only, the preferred embodiment(s) in accordance with the present invention.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Please refer to  FIG. 1  and  FIG. 2 , the nail guider is used for being disposed in a nailing device comprising a nail track, and the nail guider positioned in front of the nail track. The nail guider comprises a guiding board  10 , at least an assisting member  20  and a pushing means. 
     The guiding board  10 , positioned in front of the nail track vertically, has a first surface  11  and a second surface  12 , and the first surface  11  is opposite to the second surface  12 . The first surface  11  faces the nail track, and the guiding board  10  has at least a vertical penetrating slot  13  thereon. In a preferred embodiment of the present invention, the guiding board  10  has two vertical penetrating slots  13  thereon. The penetrating slot  13  penetrates the first surface  11  and the second surface  12  of the guiding board  10 . To increase more perfection to the nail guider of the present invention, the first surface  11  of the guiding board  10  has a guiding slot  14  extending vertically, and the guiding slot  14  is used for guiding a striking board  2  or a nail sliding along the guiding slot  14  vertically. 
     The assisting member  20  corresponds to the penetrating slot  13 , and the assisting member  20  is inserted in the penetrating slot  13 . The assisting member  20  can slide forwardly and backwardly in the penetrating slot  13 , and the assisting member  20  has an assisting end  21  and a pushing end  22 . The assisting end  21  protrudes out of the first surface  11  selectively, and the pushing end  22  is located at the second surface  12 . The assisting member  20  further comprises at least an assisting surface  211  parallel to the nailing track. In other words, the assisting surface  211  is located at two sides of the assisting end  21 , and the assisting surface  211  is used for straightening up nails. 
     The pushing means is used for pushing the pushing end  22  elastically, so the assisting end has a tendency of protruding out of the first surface  11 . In the preferred embodiment of the present invention, the pushing means comprises at least one pair of springs  30  corresponding to the assisting member  20 , and the pair of the springs  30  is horizontally positioned and vertically arranged to push the assisting member  20 . As such, a forcing power is evenly distributed to the assisting member  20  so that the assisting member  20  can move in a horizontal direction smoothly. In the preferred embodiment of the present invention, the pushing end  22  is in a structure of battlements with plural convex blocks and concave slots. Each of the springs  30  is disposed around one of the convex blocks. Moreover, the assisting member  20  can further comprise a stopping portion  24  to prevent the assisting member  20  from sliding out of the penetrating slot  13  completely. The stopping portion  24  is close to the second surface  12 , and a position of the stopping portion  24  is over a contour of the penetrating slot  13 . The stopping portion  24  abuts against the guiding board  10  to reach an effect of limiting a position of the assisting member  21 , making the assisting member  21  protrude out of the first surface  11  correctly and preventing the assisting member  21  from completely sliding out of the penetrating slot  13  when the assisting end  21  protrudes out of the first surface  11 . 
     As shown in  FIG. 3  and  FIG. 4 , the nail guider of the present invention can be adapted to be used with nails of various sizes. For instance, in  FIG. 3 , because the breadth of the nail is wider, the two assisting member  20  can be pushed toward a direction away from the nail track with being straightened up by lateral sides of the guiding slot  14 . However, in the  FIG. 4 , because the breadth of the nail is narrower, one of the two assisting member  20  can offer the assisting surface  211  for the nail to abut. As such, the nail can still be straightened up. Surely, in other possible embodiments of the present invention, the nail guider can be adapted to be used with nails of various types such as U-shaped nails and I-shaped nails. 
     Please refer to  FIG. 5 , the assisting member  20  can abut against a lateral side of the nail to straighten the nail up when the nail is ready to be strike out. And as shown in  FIG. 6 , the striking board  2  moves downwardly when a striking operation is started up. As shown in  FIG. 6A , the striking board  2  has an inner side facing the first surface  11  of the guiding board  10 , and the inner side has at least one slot  3  corresponding to the assisting member  20 . When the assisting end  21  protrudes out of the first surface  11 , the assisting end  21  is located in the slot  3 . Because the assisting member  20  can keep straightening the nail up in an up-and-down moving process of the striking board  2 , the assisting member  20  can lead the nail to be stroke out vertically. And the striking operation is finished. 
     Furthermore, as shown in  FIG. 7 , the nailing device of the present invention includes the nail guider described above, the nail track, the striking board  2  and a shell  1 . The shell  1  is used for containing the components mention above therein. The nail track is used for straightening nails up and driving the nails slide along an extending direction of the nail track. The striking board  2  strikes the nails out selectively. 
     The nail guider of the present invention enables the assisting member to evenly support on lateral sides of the nails by a feature that the assisting member can straightly slide along a horizontal direction. Thus, speaking of a former disadvantage that the nail guider with pivoting design disables the nail to be supported with even force, the nail guider of the present invention improves the former disadvantage. Moreover, the striking board has slots for containing the assisting end, so the assisting member can keep straightening the nail up in a vertical moving process of the striking board. Therefore, the nails would not be crooked or stocked when being stroke by the striking board.
