摘要
The archery device in the form of a double bow has two conventional frames (4,5) each fitted with a string (2,3) and with a further string (1) of the same length, connecting them. The first two strings form auxiliary strings, and the third string is the main string. The third string is connected to the centres of the first two strings, and is drawn back to shoot an arrow, the remaining items being arranged symmetrical to the direction of shooting. USE/ADVANTAGE - Double archery bow structure gives an improved shooting power and high arrow speed.
