Description

Repeating crossbow

Technical Field

The utility model relates to an amusement apparatus technical field specifically is a crossbow.

Background

The inventor has pointed the arrow in the new stone implement era, the stone implement with the hole in the new stone implement era is tied into the hole by using a rope, the tail of the rope is held by hands to throw two circles of the stone implement, the stone implement can be thrown far away, and the tail is very accurate because the tail is long and short, and the tail is collected to be short integrally, so that the ancient people can take the arrow character as the side of the short character. Later, metal replaces stone, when vector rays are emitted in the air, the tail of the metal flies in the air like a ribbon, so the pyramid and the ticket are combined to be named as a dart. Finally, for the convenience of entertainment, the tail is modified to a leaf-like shape, known as a dart.

History records that the arrow of Zhuge liang ten-crossbow is eight inches long, the Zhuge liang is that ancient arrow is changed to small, the Zhuge liang is eight inches long together with tail, the Zhuge liang is arranged in a cylinder and is placed on a double-crossbow to shoot, and the ten-crossbow is called as the Zhuge crossbow after shooting ten branches once.
