摘要

The crossbow has a steel and Teflon(RTM: PTFE) piston (6) provided with a metallic base that is utilized for holding the piston through a rope passage, where the crossbow is provided with a storing and disassembling system. A metallic rod is fixed to a part ended by a nozzle. The piston is activated by a rope (7), whose energy is provided by two titanium or carbon fiber arches (9). A sliding handle is engaged on the piston, and a hook (4) is adjusted by a screw lock nut (5).
