Background

The traditional slingshot generally adopts two sections of rubber or other elastic materials at two ends of an external bow frame as a force generator; the two sections of rubber or other elastic materials jointly drive the parabolic bag to run towards the horizontal direction of the rubber or other elastic materials, so that the updating and the exertion of the elastic force of the materials are limited; if the rubber is used as a power generator, the bearing force and the elastic force of the two sections of rubber are different, so that the difference of the projected stress direction caused by the difference of the acting force of the two sections of rubber in the projecting process is further caused, and the precision and the hit rate are reduced. The ejection force and the operation direction of the projectile are on the same horizontal line, so that the expansion space of the ejection force is limited; if the rubber is changed into other elastic materials with the same length, such as a metal spring, the extension degree of the power generator is reduced, and the throwing distance is limited; both rubber and other elastic materials are externally arranged force generating devices, and are easy to cause rubber bruising or exposed spring clamping injury in handheld operation. Too long segments are exposed, inconvenient to carry and easy to wind. The metal spring is exposed for a long time and is easy to be moistened and rusted. The force generator is arranged in the bow handle with larger space, so that the type of the force generator can be increased to increase the elasticity of the force generator; the horizontal acting force is changed into non-horizontal acting force, so that the rebounding force after the ejection and the emission is well offset in the bow handle, the rebounding force after the ejection and the emission are completed is reduced, and the ejection and the emission accuracy is favorably improved. The traditional slingshot is generally used for hunting small animals, can only throw a ball, and is made of a material which is not durable; the common projectiles in farming and animal husbandry also lack accuracy and more versatile functions. The utility model discloses can not only improve the accuracy of throwing, but also can use the conduct of different shapes to throw the thing, can throw cubic, column and arrow point, convenient to carry, durable and practical.
