   A connecting rod goes through an aperture and connects a fine-tuning device with a locking switch. Furthermore, a screw thereof assembles the fine-tuning device to the apparatus. A spring-biased button wherein the locking switch on the other side of the connecting rod is bonded to the locking switch by a pin, and the angle or direction of the apparatus may be changed thereby when the user is in motion. 
   The apparatus for quick assembling and disassembling of accessories for a firearm enhances the function of the firearm by enabling quick switching of accessories such as a sniperscope, an eyepiece, a red dot sight, and . . . etc. 
   To emphasize novelty and practicability of the invention, the prior art and the invention are analyzed as below: 
   DISADVANTAGES OF THE PRIOR ART 
   
       
       1. Unable to assemble and disassemble accessories to a firearm efficiently. 
       2. May cause the accessories loosen up or falling off after long-term usage. 
       3. Require tools to disassemble which is complicated and time-consuming. 
     
  
   ADVANTAGES OF THE INVENTION 
   
       
       1. Mounting base prevents accessories from loosen up or falling off. 
       2. The apparatus is efficient in switching accessories of a firearm. 
       3. The apparatus is suitable for firearms in any angle or direction. 
       4. The apparatus offers novelty and practicability. 
       5. The apparatus increases industrial competitiveness.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
   According to  FIG. 2 , an apparatus B for quick assembling and disassembling of accessories to a firearm is consisted of a fine adjustment device B 1 , a mounting base B 2 , gripping pieces B 3 , a locking switch B 4 , a spring-biased button B 5 , and a pin B 6 . Referring to  FIG. 3 , the apparatus B comprising spring apertures B 7  and springs C 1  therein to adjust degree of tightness between the apparatus B and a base E of a firearm in coordination with protruding pillars D and the fine-tuning device B 1  of the gripping pieces B 3 . A connecting rod C goes through an aperture B 9  in the mounting base B 2  and connects the locking switch B 4  and the elastic film B 5  thereafter. A screw aperture B 8  enables quick switching of the tactic equipment F (shown in  FIG. 7  &amp;  FIG. 8 ) when the apparatus B is buckled to the base E of the firearm. 
   The fine-tuning device B 1  is assembled to the apparatus B by a screw C 2  at the front end of the connecting rod C; it adjusts the degree of tightness between the apparatus B and the base E. A fixed position aperture C 3  at the back end of the connecting rod C bonds the locking switch B 4  and the elastic film B 5  together by a pin B 6 ; when the elastic film B 5  consisted of another spring C 1  in another protruding pillar D is pressed inward, the position of the apparatus B may be adjusted. After the apparatus B is adjusted to the desired position and assembled to the base E of the firearm, adjusting the fine-tuning device B 1  stabilizes the apparatus B more firmly. 
   Motions of the embodiments according to the invention are shown in  FIG. 4 ,  FIG. 5  and  FIG. 6 . When assembling an apparatus B to a base E of a firearm utilizing a locking switch B 4 , a fine-tug device B 1  and a mounting base B 2 , the locking switch B 4  is perpendicular to the base E. To utilize the locking switch B 4  lock the apparatus B in the desired position, the mounting base B 2  must be mounted into the desired position of the base E and the elastic film B 5  which locks the direction of the locking switch B 4  must be pressed inward. A fine-tuning device B 1  adjust degree of tightness of the gripping pieces B 3  to ensure that the apparatus B and the base E fit tightly. 
   As shown in  FIG. 7 , to install different types of a tactic equipment F onto an apparatus B conveniently, a fixed position ring G is added to the tactic equipment F and assembled to the apparatus B by a screw G 1  thereafter. After the apparatus B is assembled to the base E, a locking switch B 4  thereof latches. The direction and angle of the apparatus B can be changed and stabilized conveniently by pressing the elastic film B 5  inward and unlock the locking switch B 4  thereafter to reduce processing time of changing tactic equipment F while the user is in motion. 
   As shown in  FIG. 8 , a tactic equipment F of different length can be installed to a base E by an apparatus B. Furthermore, another apparatus B may be added to operate in coordination with a longer tactic equipment F to fulfill different demands of the user. 
   The apparatus B can be installed to the right or left side of a firearm with the base E to assemble the tactic equipment F in different lengths to the firearm. 
   It is of course to be understood that the embodiment described herein is merely illustrative of the principles of the invention and that a wide variety of modifications thereto may be effected by persons skilled in the art without departing from the spirit and scope of the invention as set forth in the following claims.
