Description

Bowing device

The invention relates to the related field of bow and arrow pulling, in particular to a string pulling device which can provide a user with effective labor-saving effect when pulling a string.

Bows and arrows, as the name implies, are a kind of weapon formed by the combination of bow and arrow. Both are indispensable. In use, they are stretched by the bowstrings installed between the ends of the bow arm and used with the bow and arrow to rebound with the bowstring. And the bow and arrow are fired. The bow and arrow is one of the weapons widely used in war and hunting in ancient times. However, with the evolution and change of the times, the bow and arrow have evolved from the use of war and hunting to the sports competition, archery Not only does it require extreme concentration, but also the skills of the wrists and arms and the stability of the feet. It is a fine traditional exercise that can train both the body and the mind.

However, most of today's cross-bow and bow-types are composed of a gun body, a bow arm and a bowstring that is coupled between the ends of the bow arm, wherein the gun body has a butt at the rear end. The top of the gun body is provided with an arrow groove extending to the front end to provide a bow and arrow. The arrow groove is adjacent to the top of the gun but the top of the end is coupled with a bow string holder. Before the user wants to perform archery, the bow string between the two ends of the bow arm is firstly used. Stretch to the bowstring holder, place the bow and arrow on the arrow slot, and press the arrow to the bowstring to pull the trigger at the bottom of the gun body, which can release the drawing force of the bowstring and rebound by the bowstring. Stretch and bow Launched.

However, when the bowstring is stretched, due to the tension of the bowstring itself, the user needs to hold the other side of the gun body to stretch the bowstring with one hand while stretching the bowstring, and it takes time to stretch the bowstring with one hand. Great force can pull it to the bowstring holder. In the process of stretching, if the bowstring is not carefully stretched until the bowstring holder is fixed and the bowstring rebounds, it is very likely to be rebounded. The bowstring injury to the user's arm or damage to the crossbow and the bow body can be said to be quite dangerous to the user. Therefore, relevant industry researchers have researched and developed another type of crossbow and bow, which is at the front end of the gun body. A treading piece is added to provide the user to first place the treading piece at the front end of the gun body against the ground when the bow string is stretched, and then pull the bow string by both hands by stepping on the treading part by the user's foot Stretching to the bowstring holder, although this method has achieved a relatively labor-saving effect during the stretching process, the user still needs considerable effort to stretch the bowstring to the bowstring holder, and Because of the hands Stretching the bowstring, if you accidentally fail to stretch the bowstring until the bowstring retainer is fixed, causing the bowstring to rebound, it is very likely that the bowstring of the rebound will hurt the user's foot or damage the crossbow or the bow. The situation of the body occurs. Therefore, how to provide a quicker and easier assembly and disassembly of the bow arm and the bow body of the user requires further consideration by the relevant industry, and how to improve and improve can better meet the needs of the user.

In view of the above situation, the inventors invested a lot of time to study relevant knowledge, and compared various advantages and disadvantages, carried out research and development of related products, and after many experiments and tests, finally launched a "bending bow stringing device" 』Improve the above missing to meet the needs of the public.
