Problems solved by technology

[0005] Due to the current nail-shooting bullet, the gunpowder inside it is blasted in the gun bore of the nail gun. Therefore, the nail has a huge speed and kinetic energy when it is shot out of the gun bore; this is very dangerous for the surrounding environment. Extremely large, if the nail gun hits a human body or animal by mistake, it can kill almost immediately

Embodiment Construction

[0016] Below in conjunction with accompanying drawing and embodiment the present invention is further described:

[0017] exist figure 1 In the shown embodiment, the safety nailing includes a nailing body 1, and the peripheral wall of the nailing body 1 is evenly distributed with side wings 11 that also serve as cutting and barb functions, and the side wings 11 are generally provided with 3 to 4 pieces in the circumferential direction; The rear of the nailing body 1 is provided with a closed cavity 10, which is provided with a gunpowder case 3 and a weight 4 which is located behind the powder case 3 and has a pointed cone facing the powder case; the weight 4 There is a magnetic attraction between the tail end 12 of the nail body 1 .

[0018] The gunpowder shell 3 is wrapped with gunpowder and a primer. After the sharp cone of the weight 4 hits the gunpowder shell 3, it first squeezes the primer, causing the primer to explode, thereby igniting the gunpowder.

[0019] The nail...

Abstract

The invention provides a safety firing pin. The safety firing pin comprises a firing pin body, wherein side wings for cutting and barbing are uniformly distributed on the peripheral wall of the firing pin body; a sealed cavity is arranged behind the firing pin body; the sealed cavity is internally provided with a gunpowder shell and a heavy block which is arranged behind the gunpowder shell and has a pointed cone facing the gunpowder shell; a magnetic suction force is formed between the heavy block and the tail end of the firing pin body. The safety firing pin has a relatively low muzzle speed and can generate an armor-piercing action only if the safety firing pin hits a hard object so that the safety is good.

Description

[0001] technical field [0002] The invention relates to the field of hardware tools, in particular to a nail-shooting. [0003] Background technique [0004] The nail gun is an extremely beneficial tool for climbing in the wild and emergency escape from high-rise buildings. It mainly relies on gunpowder gas to drive the nail bullet, so that the nail can directly drill into the surface of hard objects such as walls and rocks. [0005] Due to the current nail-shooting bullet, the gunpowder inside it is blasted in the gun bore of the nail gun. Therefore, the nail has a huge speed and kinetic energy when it is shot out of the gun bore; this is very dangerous for the surrounding environment. Extremely large, if the nail gun hits a human body or animal by mistake, it can kill almost immediately. [0006] Contents of the invention [0007] In view of the above problems, the purpose of the present invention is to provide a safety nail, which has a relatively low exit speed, an...
