Description

Ceiling gun

The invention relates to a ceiling gun.

Press, the general ceiling gun is used to hit the gunpowder with gunpowder into a hard target (such as the roof of the room), so that the gunpowder nail can be assembled with the light steel frame for the installation of the ditch industry. For ceiling, electric fan or cold air outlet, the conventional ceiling gun has a retractable gun body, a guiding tube and a needle assembly. The needle tube assembly is slidably arranged in the guiding tube, and the needle assembly includes a moving action. a needle-punching member and a needle-roding rod for guiding the moving direction of the needle-punching assembly. The guiding tube has a small diameter section and a large diameter section integrally formed, and the small diameter section has a fine hole only The needle is traversed, and a large chamber has a chamber for the needle rod sliding limit. When the gun body is forced against the target, the gun body will expand and contract and trigger the shot assembly The needle moves in the direction of the gunpowder. When the needle member protrudes out of the small diameter section and hits the gunpowder nail, the gunpowder in the gunpowder nail is ignited and exploded to shoot the gunpowder and hit the target.

However, the guide tube of the conventional ceiling gun has a large diameter section and a small diameter section, and is manufactured by first drilling a small hole of a small diameter section when a substrate is used, and then using the second time.
