| 摘要 |
The present invention relates to a new type of speargun which uses a continuously-variable-transmission drive system for energy storage and transmission of motion of the ejection device (which may be a piston, a rubber element or a spring) to the spear. The continuously-variable-transmission drive system consists of a shaft (10), the winding drums (8-8.1-9) and the ropes (4), (11). In order to double, triple and quadruple the energy storage to the ejection device, the drive system consists of the respective number of shafts, winding drums and ropes. |
