1. An anti dry fire trigger device comprising:
a holder including a front end, a rear end, a channel extending backward from a middle section of a front end of the holder, and an accommodation groove defined on a rear side of the channel in the holder, wherein the accommodation groove has two defining orifices formed on at least one of two sides of the accommodation groove;
a fixer rotatably connected adjacent to a front end of the holder, and the fixer including a push portion and a stop portion which are formed in a direction of the fixer, a limitation portion and a first rotatable coupling portion which are defined opposite to the push portion and the stop portion, wherein the fixer is rotatably connected with the holder by using the first rotatable coupling portion, a first spring is defined between the fixer and the holder so that the fixer is pushed by the first spring to urge the push portion of the fixer to extend into the channel and the limitation portion is configured to limit the holder;
a string hook rotatably connected in the holder located on a rear side of the fixer, wherein the string hook includes a hooking portion formed on a first end thereof, an abutting portion formed on a second end of the string hook, a second rotatable coupling portion defined between the hooking portion and the abutting portion, such that the string hook is rotatably connected with the holder by using the second rotatable coupling portion, and a second spring is defined between the string hook and the holder so that the string hook is pushed by the second spring and the hooking portion of the string hook removes from the channel in a normal state;
a connection trigger rotatably connected proximate to a bottom of the holder, the connection trigger including a fastening portion formed on a first end of the connection trigger, and the connection trigger including a third rotatable coupling portion, such that the connection trigger is rotatably connected with the holder by using the third rotatable coupling portion, and the connection trigger is not triggered in the normal state;
a safety switch slidably received in the accommodation groove, and the safety switch including two slidable posts extending from at least one side of two sides of the safety switch into the two defining orifices of the holder so that the safety switch is limited on an opening position and a closing position to switch; and
an engagement element slidably received in the holder, a first end of the engagement element connected with the safety switch, and the engagement element includes a defined portion extending from a second end thereof so that the engagement element is switched to move forward and rearward with the safety switch; wherein when the defining portion of the engagement element is stopped by the push portion of the fixer, the safety switch is limited to not slide to the opening position, thus obtaining anti dry fire trigger; when the push portion of the fixer is pushed upward by the arrow to drive the fixer to rotate, and the stop portion of the fixer does not engage with the engagement element to remove the engagement element from the stop portion of the fixer, thus sliding the safety switch to the opening position.
