Description

Folding bow with string pulling device

The present invention relates to the field of archery sports equipment, and more specifically, to a bow pulling device.

The basic structure of a crossbow or a folding bow generally includes a bow body, a bow arm, and a bow string combined between the two ends of the bow arm; a grip is provided below the rear end of the bow body for the archer to hold, and an arrow slot is provided at the top of the bow body for the bow and arrow Placed at the rear end of the bow body corresponding to the arrow slot is provided with a string holder, the bow string on the bow arm can be stretched to the string holder to be in a tight state; the trigger is located under the bow body near the grip Position, the trigger can control the string holder to release the bowstring.

Before archery, first stretch the bowstring between the two ends of the bow arm to the string holder, then place the bow and arrow in the arrow slot, put the tail of the arrow against the bowstring on the string holder, press the trigger, and fix the string The device releases the bowstring and fires the bow and arrow out by the resilience of the bowstring.

The action of stretching the bowstring is to hold the grip with one hand, and pull the bowstring backward with the finger with the other hand. Based on the elasticity and tension of the bowstring itself, the closer the bowstring is to the pullstring holder, the greater the force to stretch the bowstring. Insufficient stretching strength or sliding of the hand will cause the bow string to rebound, which will cause damage to the bow arm or body, and even hurt the archer's arm or finger.

In order to solve the above problems, the invention patent TWI591314 of the Republic of China proposes a safe and labor-saving string pulling device.
