Abstract:
A trigger labor-saving structure of a crossbow, the crossbow includes a body, an arcuate limb, and a trigger assembly. The limb is mounted adjacent to a front end of the body and intersects with the body, and the limb includes a bowstring. The trigger assembly includes: a trigger seat arranged on the body, a trigger partially accommodated in the trigger seat and downward extending out of the trigger seat, the trigger having a stop face; a string hook member housed in the trigger seat and including an engagement face corresponding to the stop face; and at least one concave portion formed on the engagement face of the string hook member and defined between the first periphery and the second periphery, such that frictional resistance between the stop face and the engagement face reduces.

Claim (Index 1):
A trigger labor-saving structure of a crossbow, the crossbow including: a body, a limb, and a trigger assembly, the limb being in an arc shape and being mounted adjacent to a front end of the body, and the limb intersecting with the body and including a bowstring fixed on two ends of the limb, wherein the trigger assembly includes:\n a trigger seat arranged on the body of the crossbow; a trigger partially accommodated in the trigger seat and downward extending out of the trigger seat so as to control triggering of the crossbow, the trigger having a stop face defined on an end of the trigger inside the trigger seat a string hook member housed in the trigger seat so as to hook the bowstring of the crossbow after the bowstring being pulled rearward, and the string hook member including an engagement face formed on an end of the string hook member corresponding to the stop face of the trigger, and the engagement face having a first periphery and a second periphery opposite to the first periphery; and at least one concave portion being formed on the engagement face of the string hook member and defined between the first periphery and the second periphery of the engagement face, such that frictional resistance between the stop face and the engagement face reduces without influencing structural strength of the string hook member.
