Gun aiming device

Abstract

A gun aiming device includes a base body, an aimer, a first and second rotating adjuster and an elastic blade. The positioning base body has a through hole. The aimer installs in the through hole. A first plane disposes on the aimer's one side. A second plane disposes on a side of the aimer perpendicular to the first plane. The first rotating adjuster penetrates the positioning base body's one side and the first rotating adjuster's distal end abuts against the first plane. The second rotating adjuster penetrates the positioning base body's one side and the second rotating adjuster's distal end abuts against the second plane. The elastic blade disposes in the through hole and the elastic blade's distal end abuts against the aimer. The elastic blade locates on a side corresponding to the first and second rotating adjusters to jointly achieve three-point supporting and positioning of the aimer.

1 . A gun aiming device joined and fixed on a gun, said gun aiming device comprising:
 a positioning base body, a through hole axially penetrating said positioning base body;   an aimer installed in said through hole, a first plane being disposed at one side of said aimer, a second plane being disposed at a side of said aimer perpendicular to said first plane;   a first rotating adjuster penetrating one side of said positioning base body, a distal end of said first rotating adjuster exactly abutting against said first plane of said aimer;   a second rotating adjuster penetrating one side of said positioning base body, a distal end of said second rotating adjuster exactly abutting against said second plane of said aimer; and   an elastic blade disposed at a side end in said through hole, a distal end of said elastic blade exactly abuts against said aimer, said elastic blade being exactly located at a side corresponding to said first and second rotating adjusters to jointly achieve three-point supporting and positioning of said aimer;   whereby said first rotating adjuster and said second rotating adjuster are adjusted respectively for horizontal-axis motion and vertical-axis motion of said aimer to calibrate the central position of said aimer.   
     
     
         2 . The gun aiming device as claimed in  claim 1 , wherein the distal end of said elastic blade has an abutting surface that exactly abuts against said aimer. 
     
     
         3 . The gun aiming device as claimed in  claim 1 , wherein the distal end of said first rotating adjuster has a circular arc-shaped first contact surface that correspondingly contacts said first plane. 
     
     
         4 . The gun aiming device as claimed in  claim 1 , wherein the distal end of said second rotating adjuster has a circular arc-shaped second contact surface that correspondingly contacts said second plane. 
     
     
         5 . The gun aiming device as claimed in  claim 1 , wherein said through hole is rectangular. 
     
     
         6 . The gun aiming device as claimed in  claim 1 , wherein said first plane is disposed at a bottom side of said aimer. 
     
     
         7 . The gun aiming device as claimed in  claim 1 , wherein said second plane is disposed at a right side of said aimer. 
     
     
         8 . The gun aiming device as claimed in  claim 1 , wherein a first adjusting hole and a second adjusting hole axially perpendicular to said through hole are respectively disposed at two vertically adjacent sides of said positioning base body, and said first rotating adjuster is locked from an outer end of said positioning base body into said first adjusting hole to abut against said first plane of said aimer, and said second rotating adjuster is locked from an outer end of said positioning base body into said second adjusting hole to abut against said second plane of said aimer. 
     
     
         9 . The gun aiming device as claimed in  claim 1 , wherein said first rotating adjuster is a screw. 
     
     
         10 . The gun aiming device as claimed in  claim 1 , wherein said second rotating adjuster is a screw. 
     
     
         11 . The gun aiming device as claimed in  claim 1 , wherein an elastic supporting unit is disposed between said through hole of said positioning base body and said aimer.
