Referring to FIGS. 1 to 3 , an embodiment of the novel canopy nail gun 100 is suitable for loading a gunpowder bullet 200 and a nail 300, so as to use the gunpowder bullet 200 to fire the nail 300. The gunpowder bullet 200 has a flange 201 at one end, and the nail 300 has a nail head 301 and a nail tip 302. The nail head 301 has a protrusion 301a protruding in a direction opposite to the extension direction of the nail tip 302 and capable of colliding with the flange 201 of the gunpowder bullet 200. The canopy nail gun 100 includes a nail gun module 1, a hammer module 2, an outer tube 3, and a bullet ejector tube 4.

The nail gun module 1 includes a gun barrel 11 and a striker 12, and a return spring 13. The gun barrel 11 has a loading chamber 111 located at the front section and suitable for loading the gunpowder bullet 200 and the nail 300, and a receiving chamber 112 located behind the loading chamber 111. When the loading chamber 111 loads the gunpowder bullet 200 and the nail 300, the flange 201 of the gunpowder bullet 200 faces forward, the nail tip 302 of the nail 300 faces forward and the nail head 301 faces backward, and the nail 300 is located in front of the gunpowder bullet 200.

The loading cavity 111 has a first hole portion 111a, a second hole portion 111b and a third hole portion 111c arranged from back to front with hole diameters increasing from small to large, a loading step portion 111d located between the first hole portion 111a and the second hole portion 111b, and a nailing step portion 111e located between the second hole portion 111b and the third hole portion 111c. The loading step 111d is used to stop the flange 201 of the powder bullet 200 from moving backward to position the powder bullet 200, and the nailing step 111e is used to stop the nail head 301 of the nail 300 from moving backward to position the nail 300, so that the powder bullet 200 and the nail 300 are not in contact or the contact force is less than a preset value, thereby avoiding excessive compression between the nail 300 and the powder bullet 200 before firing, so as to prevent the primer of the powder bullet 200 from being deformed and affecting the success rate of firing.

The accommodating chamber 112 has a limiting groove 112a. The striker 12 is slidably disposed in the accommodating chamber 112, and the striker 12 has a limiting sliding portion 121 slidably disposed in the limiting groove 112a. The front and rear positions of the striker 12 are limited by the cooperation between the limiting groove 112a and the limiting sliding portion 121. The return spring 13 is disposed between the barrel 11 and the striker 12 and drives the striker 12 to return to its original position.

The hammer module 2 is disposed at the rear end of the nail gun module 1. The hammer module 2 includes a hammer 21 having a receiving groove 211 formed inwardly concave from the side, a hammer tube 22 arranged at the rear end of the gun barrel 11 of the nail gun module 1, a firing sleeve 23 slidably arranged in the hammer tube 22, a return spring 24 arranged between the hammer tube 22 and the firing sleeve 23, a firing spring 25 arranged in the firing sleeve 23 and located behind the hammer 21, a firing pin 26 arranged in the receiving groove 211 of the hammer 21 and having an arc-shaped outer surface, and a support spring 27 arranged between the bottom of the receiving groove 211 and the firing pin 26 and driving the firing pin 26 to protrude outward from the receiving groove 211.

The hammer tube 22 has a small-diameter portion 221 and a large-diameter portion 222 arranged in a front-to-back manner inside the hammer tube 22 , and a stopper portion 223 between the small-diameter portion 221 and the large-diameter portion 222 .

The hammer 21 is protruding from the front end of the firing sleeve 23 and is disposed in the firing sleeve 23 and can slide forward and backward relative to the firing sleeve 23. The firing spring 25 is disposed behind the hammer 21 and can drive the hammer 21 to slide forward relative to the firing sleeve 23.

The firing sleeve 23 has a firing tube 231 for accommodating the hammer 21 and the firing spring 25, and a connecting tube 232 disposed at the rear end of the firing tube 231 and protruding rearward from the hammer tube 22. The connecting tube 232 has a first connecting end 232a facing forward and connected to the firing tube 231, and a second connecting end 232b facing rearward and opposite to the first connecting end 232a. The second connecting end 232b of the connecting tube 232 can be used to assemble an auxiliary rod (not shown), which is used for the user to hold, so that the user can more easily put the nail 300 at the front end of the canopy nail gun 100 against the ceiling.

The firing sleeve 23 can slide back and forth between an initial position at the rear and a firing position at the front relative to the hammer tube 22. Through the sliding of the firing sleeve 23 relative to the hammer tube 22 and the sliding of the hammer 21 relative to the firing sleeve 23, the hammer 21 can slide back and forth between a ready position at the rear and a striking position at the front relative to the nail gun module 1.

The outer tube 3 is disposed outside the gun barrel 11 of the nail gun module 1 and covers the loading chamber 111 to reduce the sound of the gunpowder bomb 200 when it explodes and prevent dust leakage during the explosion.

The gun barrel 11 of the nail gun module 1 also has a plurality of long holes 113 connected to the accommodating cavity 112 and extending forward and backward. The ejector tube 4 is sleeved on the gun barrel 11, and the ejector tube 4 has a plurality of ejector protrusions 41 extending inward and extending from the long holes 113 into the accommodating cavity 112 respectively. The ejector protrusions 41 of the ejector tube 4 can slide forward and backward along the long holes 113.

In the unstressed state, when the firing sleeve 23 is in the initial position, the hammer 21 is in the prepared position.

Referring to FIG. 4 , when in use, the nail 300 at the front end of the canopy nail gun 100 abuts against the ceiling, and the firing sleeve 23 is squeezed by the auxiliary rod and slides forward from the initial position. Since the firing pin 26 protrudes outward from the accommodating groove 211 of the hammer 21, the firing pin 26 is forwardly stuck against the stopping step 223 of the hammer tube 22. At this time, the forward movement of the hammer 21 is blocked, and the firing spring 25 is compressed and accumulates an elastic restoring force.

Referring to FIG. 5 , when the firing sleeve 23 is continuously squeezed and slides forward to the firing position, the firing pin 26 is pressed inward into the accommodating groove 211 to pass forward over the stop step 223, and the elastic restoring force accumulated by the firing spring 25 acts on the hammer 21, causing the hammer 21 to move forward to the striking position. At this moment, the hammer 21 moves from the prepared position to the striking position due to the elastic restoring force of the firing spring 25, and the hammer 21 quickly slides forward and strikes the striker 12 of the nail gun module 1 from the rear, causing the striker 12 to strike the gunpowder bullet 200 forward, thereby causing the flange 201 of the gunpowder bullet 200 to strike the protrusion 301a on the nail head 301 to cause the gunpowder bullet 200 to explode, and the explosion of the gunpowder bullet 200 causes the nail 300 to be nailed into the ceiling. After the firing is completed, the return spring 24 drives the firing sleeve 23 to move toward the initial position, and the hammer 21 also returns to the prepared position (returns to the state shown in FIG. 2 ).

The hammer 21 of the hammer module 2 can slide forward and hit the striker 12 of the nail gun module 1 from the rear, so that the striker 12 hits the gunpowder bullet 200 forward. When in use, it is not necessary to keep the canopy nail gun 100 at a certain distance from the ceiling and hit the ceiling upward with force, so as to avoid the problem of the canopy nail gun 100 being offset and causing the position of the nail 300 to be inaccurate.

Referring to FIG. 6 , after the firing is completed, the ejector tube 4 can be operated to slide forward, and the ejector protrusions 41 of the ejector tube 4 push the striker 12 forward, and the striker 12 extends forward into the loading chamber 111 of the barrel 11 to push the gunpowder bullet 200 (see FIG. 2 ), so that the gunpowder bullet 200 after the explosion is separated forward from the loading chamber 111 of the barrel 11. Then, the return spring 13 drives the striker 12 and the ejector tube 4 to return backward.

In summary, the hammer 21 of the hammer module 2 can slide forward and strike the striker 12 of the nail gun module 1 from the rear, so that the striker 12 strikes the gunpowder bullet 200 forward. When in use, it is not necessary to keep the canopy nail gun 100 at a certain distance from the ceiling and strike the ceiling upward with great force, so as to avoid the problem of the canopy nail gun 100 being offset and causing the nail 300 to be inaccurately positioned. In addition, the present invention uses the loading step 111d and the nailing step 111e to prevent the powder bullet 200 and the nail 300 from contacting or to reduce the contact force to a preset value, thereby preventing the nail 300 and the powder bullet 200 from being over-compressed before firing, thereby preventing the primer of the powder bullet 200 from being deformed and affecting the success rate of firing.

However, the above is only an example of the implementation of the present invention, and it cannot be used to limit the scope of the implementation of the present invention. All simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still within the scope of the present patent.
