The other end of the wire behind the fencer is in a cable box that can stretch the wire. Just like the tape measure commonly used by everyone, its stretching length can extend to the bottom line of the opponent's field, which means that it is not affected when attacking the opponent. There is a lockable socket at the back of the swordsman's sword suit, which extends from the socket to the hand holding the sword.
Then it is connected to the sword through the plug in the sleeve. The head of the sword has a retractable electronic actuator similar to a switch, and the effective part of the athlete's sword suit is covered with a layer of metal woven net. In this way, when the sword head pierces the effective part of the opponent, the light will light up and the score will be automatically integrated. When the sword head pierces the invalid part, the invalid light is on and no score is scored.
The fencing competition is held on a metal track with a length of 14m, a width of 1.5-2.5m and a height of 10-50cm. Fencers should wear professional clothes.
Fencing clothes are white three-sword sets (coat, trousers, protective vest), made of bulletproof materials to ensure safety; Fencing socks are white stockings; Shoes are special fencing shoes; Gloves are white sheepskin products; In foil and sabre competitions, athletes wear conductive metal clothes outside their clothes; The mask covers all the fragile parts of the head.
