which part of the crossbow is used to draw the bow

The part of the crossbow that is used to draw the bow is the string. The string is pulled back (drawn) to cock the crossbow, creating the tension needed to shoot the bolt. Some crossbows use a draw cord or a hand crank to help draw the string back, especially for higher draw weight bows. Additionally, the stirrup is used to secure the crossbow with the foot while drawing the string to stabilize the process. Thus, the string itself is the critical component used to draw the bowstring back, while tools like the crank or stirrup assist in the drawing process.
