Machine gun principle
Hiram maxim, the inventor of the machine gun, was originally an American electrical engineer. 188 1 year, he met a friend at the Paris Expo and said to him, "If you want to make a lot of money, you must invent something that will make it easier for Europeans to fight." Mark Bi was deeply influenced and immediately set about developing automatic rapid-fire machinery. A few years ago, Maccabee shot with a barbed gun, and his arm was beaten black and blue by the back of the gun. At that time, he deviated in order to make better use of this energy. In Qian Fang, he developed a gun, which can use the reaction force generated after the bullet is fired to empty the shell and install a new sub-firing pin. Since each bullet can trigger the next bullet, the shooter can shoot automatically and continuously as long as he pulls the trigger. At the same time, Ma Keqin designed loading cups with canvas belts which are difficult to load, ensuring the supply of ammunition, and each canvas belt can hold 250 rounds of ammunition. In order to solve the cooling problem of the machine gun, he made a water jacket, which contained seven kinds of liquid and wrapped it on the gun. This made it the first real machine gun in the world. People call it the Ma Keqin gun, which weighs 50 pounds and fires 600 bullets every minute. Ma Keqin successfully invented the machine gun in 1993, which was highly valued by the Prince of Wales and British defense officials. After watching Ma Keqin's performance, they bought the patent of Ma Keqin gun and manufactured it in large quantities. 1898 was equipped with British troops.
1898, in the battle of Thurman in Suwan province, the British general Dreshaw Kilani used the Ma Keqin gun for the first time in a large-scale military conflict and won a great victory.
