A course of crossbow training

The graphic process of crossbow practice is as follows:

First, the basic structure of the crossbow.

A crossbow consists of a crossbow arm, a crossbow, a bowstring and a trigger. The crossbow arm is the support of the crossbow and is responsible for stabilizing the crossbow. The crossbow is composed of a bow arm and a bow back, and both ends are fixed on the crossbow arm respectively. Bow strings connect the two ends of the crossbow and are responsible for storing and releasing energy. The trigger is a device that controls the firing of crossbows.

Second, the steps of making crossbows:

1. Making crossbow arm: Select suitable wood or metal material and process it into the shape of crossbow arm, with a length of about 30-40cm. A groove is machined at one end of the crossbow arm to fix the bowstring.

2. Making crossbows: According to personal preferences and needs, choose suitable materials for the bow arm and the bow back. The bow arm and the bow back are respectively processed into the shape of a bow, and one end of the bow back is processed with a protrusion, which is fixed in the groove of the bow arm.

3. Making bowstring: Choose a suitable rope or rubber band, and fix both ends on the groove of the crossbow arm and the protrusion of the crossbow.

4. Making a trigger: Choose a suitable piece of metal or wood material to make a lever-shaped trigger. The other end of the trigger is fixed on a button to control the firing of the crossbow.

5. Assembly: Assemble the crossbow arm, crossbow, bowstring and trigger together to ensure that all parts are firmly connected.

Style of crossbow:

1. Traditional crossbows: Traditional crossbows have a long history in China and originated from ancient wars. It is mainly composed of crossbow arm, crossbow, bowstring and crossbow machine. The crossbow arm of a traditional crossbow is usually made of wood or bamboo, and the crossbow uses an angle bow or an iron bow. This crossbow has a short range, about 100-200m, but it is powerful and suitable for close combat.

2. Modern competitive crossbows: Modern competitive crossbows are mainly used in archery competitions, so they pay attention to accuracy and stability. They are usually made of high-strength alloy, carbon fiber and other materials, which are light and durable. The bowstring material of modern competitive crossbows is also different, using nylon thread or carbon thread. This crossbow has a range of about 150-300 meters, and its power is relatively small.

3, hunting crossbows: hunting crossbows are suitable for wild hunting, so they need to have high lethality. They are usually made of composite materials and have good wear resistance and aging resistance. The bow arm and bowstring of the hunting crossbow have high strength and the range can reach 200-400 meters. Some hunting crossbows are also equipped with sights to improve shooting accuracy.

4. Military crossbows: Military crossbows are mainly used in battlefield operations with diverse needs. They may be innovative in structure to adapt to different operational environments. Military crossbows are usually made of high-strength alloys and composite materials, which have high durability and stability. Range and power vary according to tactical requirements, but they are generally very lethal.
