Patent ID: 11512921

Abstract:
A crossbow includes a frame, where the frame is provided with an arrow track for placing an arrow; the crossbow includes at least one limb; the limb includes a fixed end and a movable end; the movable end is moved toward the fixed end under pressure, such that two sections bent in opposite directions are formed on the limb to make the limb wave-shaped; the movable end is moved in a reverse direction to make the limb restored; and a primary string of the crossbow is directly or indirectly connected to the movable end of the limb. The limb of the crossbow can generate large elastic potential energy and can reduce the kinetic energy consumed by translation, and avoids the problem of different strokes between multiple limbs. The crossbow prevents the winding wheels from translating to consume the kinetic energy, such that the arrow can gain sufficient kinetic energy.
