Patent attributes
The structure discloses a crossbow head assembly structure, comprising a main bracket, crossbow pieces, pulleys, a main string, and auxiliary strings. The invention improves the assembling method of the crossbow piece and the hanging method of the crossbow string, and is equipped with a string adjusting device. Advantageous effects: 1. the forward speed of the pulley when the arrow is shot is superimposed on the forward speed of the main string; 2. the weight of the pulley can be reduced, so that the shooting speed of the crossbow arrow can be increased, and the impact of the pulley on the crossbow string can be reduced by the sudden stop of the pulley; no matter which crossbow string is broken, the other crossbow strings will be completely relaxed; 3. the crossbow string can be assembled without a bow opener; moreover, the accuracy of shooting can be adjusted very conveniently.
