Title: Combination of screw nail gun and nail belt

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to nail gun technology and more particularly to a combination of screw nail gun and nail belt. 
     2. Description of the Related Art 
     Referring to  FIG. 1 , a regular screw nail gun  1  comprises a gun body  11  and a nailing nozzle  12  connected to the front end of the gun body  11 . Further, a nail belt  2  is mounted in the screw nail gun  1 . The nail belt  2  comprises a belt body  21  and a plurality of screw nails  22 . The belt body  21  of the nail belt  2  is inserted into the nailing nozzle  12  of the gun body  11 . 
     The screw nail  22  to be nailed is not kept inside the nailing nozzle  12 . The user can simply use the nailing nozzle  12  for aiming. Using the nailing nozzle  12  for aiming cannot keep the screw nail in accurate alignment with the workpiece, lowering the construction quality. 
     Further, the belt body  21  of the nail belt  2  is molded from a flexible plastic material. During operation of the screw nail gun  1 , the nail belt  2  may vibrate, interfering with the nailing operation. 
     Therefore, it is desirable to provide a combination of screw nail gun and nail belt that eliminates the aforesaid drawbacks. 
     SUMMARY OF THE INVENTION 
     The present invention has been accomplished under the circumstances in view. It is one object of the present invention to provide a combination of screw nail gun and nail belt, which facilitates nailing operation and improves construction quality. 
     To achieve this and other objects of the present invention, a combination of screw nail gun and nail belt comprises a screw nail gun and a nail belt. The screw nail gun comprises a gun body extending along an axis perpendicular to a nailing surface, a nailing nozzle connected to the front end of the gun body and having a front alignment face, a nail holder connected to the nailing nozzle and defining with the nailing surface an acute angle, and a cover covering the nail holder and defining with the nail holder a nail groove. The nail belt comprises a belt body set in the nail groove and a plurality of screw nails fastened to the belt body. One screw nail is positioned in the nailing nozzle for nailing. The screw nail that is positioned in the nailing nozzle has the head thereof partially protruding beyond the front alignment face of the nailing nozzle to facilitate alignment during nailing. 
     The invention keeps the screw nail that is positioned in the nailing nozzle in such a position that the head of the screw nail partially protrudes beyond the front alignment face of the nailing nozzle to facilitate alignment during nailing, improving nailing precision. Further, based on the design of the acute angle defined between the nail holder and the nailing surface, the screw nail gun can be operated conveniently in a corner area. 
    
    
     
       BRIEF DESCRIPTION OF THE DRAWINGS 
       Other and further benefits, advantages and features of the present disclosure will be understood by reference to the following specification in conjunction with the accompanying drawings, in which like reference numbers indicate like elements of structure. 
         FIG. 1  is a schematic side view showing a combination of screw nail gun and nail belt according to the prior art. 
         FIG. 2  is a schematic side view showing a combination of screw nail gun and nail belt according to the present invention. 
     
    
    
     DETAILED DESCRIPTION OF THE INVENTION 
     Referring to  FIG. 2 , a combination of screw nail gun and nail belt is shown comprising a screw nail gun  2  and a nail belt  3 . 
     At first, define an axis L and a nailing surface S perpendicular to the axis L. 
     The screw nail gun  2  comprises a gun body  31  extending along the axis L, a nailing nozzle  32  connected to the front end of the gun body  31 , a nail holder  33  connected to the nailing nozzle  32 , a cover  34  covering the nail holder  33 , and a nail groove  35  defined in between the nail holder  33  and the cover  34 . 
     The nailing nozzle  32  has a front alignment face  321  at the front side. 
     The nail groove  35  is adapted for receiving the nail belt  4 . The nail holder  33 , cover  34  and nail groove  35  define with the nailing surface S an acute angle θ. According to the present preferred embodiment, this acute angle is within the range of 200°˜35°, or preferably 26°. 
     Based on the design of the acute angle  0  between the nail holder  33  and the nailing surface S, the screw nail gun  3  can be operated conveniently in a corner area. Further, under a normal work condition, the screw nail gun  3  has the characteristic of ease of use, improving construction quality. 
     The nail belt  4  is set in the nail groove  35 , comprising a belt body  41  and a plurality of screw nails  42  fastened to the belt body  41 . 
     According to the present preferred embodiment, the belt body  41  of the nail belt  4  is injection molded from a hard plastic material fitting the angle of slope of the nail groove  35 . Further, because the belt body  41  is from a hard plastic material and set in the nail rove  35  in proximity to the nailing nozzle  32 , the nail belt  4  does not vibrate during the use of the screw nail gun  2 . 
     Further, injection molding of the belt body  41  must match to the acute angle θ between the nail holder  33  and the nailing surface S, i.e., when the acute angle θ between the nail holder  33  and the nailing surface S is changed, the injection angle of the belt body  41  must be relatively changed. 
     One of the screw nails  42 , namely, the screw nail  421  to be nailed protrudes beyond the alignment face  321  of the nailing nozzle  32  at a distance about 2˜3 mm. The head of the screw nail  421  to be nailed is aimed at a hole B on the workpiece, for example, hinge A that is to be driven into the nailing surface S. By means of aiming the head of the screw nail  421  to be nailed at the hole B of the workpiece A instead of aiming the nailing nozzle  32  at the hole B of the workpiece A, the nailing accuracy is improved, thereby improving construction quality. 
     As stated above, in order to facilitate operation and to improve construction quality, the invention improvements on the combination of the screw nail gun  3  and the nail belt  4  in two points. At first, the nail groove  35  is designed to define with the nailing surface S an acute angle θ, and the belt body  41  of the nail belt  4  is injection molded from a hard plastic material to match to the acute angle θ. During operation, the nail holder  33  and the belt body  41  do not touch the nailing surface S directly, increasing the level of convenience of use. 
     Further, the head of the screw nail  421  to be nailed protrudes partially beyond the alignment face  321  of the nailing nozzle  32 , facilitating accurate alignment and effectively improving construction quality. 
     A prototype of combination of screw nail gun and nail belt has been constructed with the features of  FIG. 2 . The combination of screw nail gun and nail belt functions smoothly to provide all of the features disclosed earlier. 
     Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims.
