The present invention relates to a high speed internal nail.

According to the general nail gun, the impact of the gunpowder explosion is used to hit the nail into the target (such as cement ceiling) to fix a fixing member (such as the L-shaped plate for the light steel frame) with the target. Then, a fixing rod is connected to the fixing member, and the fixing rod can be used for installing a light steel frame, and the installation process is too troublesome, so that an internal nail is invented, and the internal nail has a nail body connection. One of the cylinders has an internal thread on the inner wall of the cylinder. When the nail body hits the target object, a rod body can be screwed to the inner wall of the cylinder body, so that the installation process is convenient, TWM525248 The high-speed internal nails disclosed are such.

However, such conventional high-speed internal nails cannot be effectively fixed in the cylinder due to the hard material of the inner wall of the cylinder and the internal thread, so that the metal shell is too small. Any movement inside the cylinder, and if the metal shell and the internal thread are tightly fitted, it is easy to cause the internal thread to be damaged and cannot be screwed with the fixed rod, which is extremely limited in use, so the conventional high-speed internal nail is only available. The soft shell powder is filled in the cylinder, and the soft shell gunpowder needs to be installed at the bottom of the cylinder so that the soft shell gunpowder does not slip again when the needle of the nail gun hits the soft shell gunpowder, so that it cannot be detonated smoothly. The process of installing soft shell gunpowder is extremely inconvenient, and there are drawbacks that need to be improved.

Therefore, it is necessary to provide a novel and progressive high-speed internal nail to solve the above problems.

The main object of the present invention is to provide a high-speed internal nail, comprising a body and a connecting member, which can be connected with a hard shell or a soft shell powder and is convenient to install without causing damage to the internal thread portion of the barrel. It can prevent the gunpowder from moving relative to the body to improve the convenience of use.

To achieve the above object, the present invention provides a high speed internal nail comprising a body and a connecting member. The body includes a nail body and a cylinder body.
