[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] See Figs. 1-3 An automatic nail gun for tablecloths includes a mounting plate 1 and a mounting base 2. The mounting plate 1 and the mounting base 2 are movably connected by a spring rod 3. The mounting plate 1 has a connection hole for connecting a nail gun on its inner side. Several clamping mechanisms are fixedly installed on the side wall of the mounting base 2. The clamping mechanism includes a spring support 4. A clamping block 5 for clamping a hot melt pad is slidably connected to the inner side of the open end of the spring support 4, and the clamping end of the clamping block 5 is located outside the open end of the spring support 4.

[0022] In this solution: by connecting the nozzle of the nail gun to the inside of the mounting plate 1, and simultaneously, the clamping block 5 on the card holder 2 can clamp and fix the hot melt gasket and the metal gasket, and center the hot melt gasket and the metal gasket in the card holder 2. Thus, after the hot melt gasket and the metal gasket are fixed in the card holder 2, the nozzle of the nail gun can automatically align with the mounting holes of the hot melt gasket and the metal gasket. Furthermore, when the nail gun is firing, it can push the mounting plate 1 to compress the spring rod 3 and move it linearly towards the card holder 2, so that the nozzle of the nail gun is close to the gasket. This not only makes it more convenient to fix the hot melt gasket on the geotextile, but also effectively improves the accuracy of fixing the nail on the hot melt gasket. It should be noted that the clamping end of the clamping block 5 has an inclined slope, so that when the hot melt gasket is installed into the card holder 2, the clamping block 5 can be smoothly pushed to retract in the spring support 4 and the clamping end of the clamping block 5 can be stably pressed against the side of the hot melt gasket.

[0023] A fixing seat 6 is fixedly connected to the outside of the connecting hole of the mounting plate 1, and a through hole communicating with the connecting hole is opened on the inside of the fixing seat 6.

[0024] In this embodiment, the setting of the fixing base 6 and the connecting hole can increase the contact area between the mounting plate 1 and the nail gun head, thereby improving the stability of the nail gun on the mounting plate 1.

[0025] An adjusting sleeve 7 is threadedly connected to the outside of the fixed base 6. A rubber block 8 is fixedly connected to the fixed base 6 on the inside of the adjusting sleeve 7. A straight hole communicating with the through hole on the inside of the fixed base 6 is opened on the inside of the rubber block 8. When the adjusting sleeve 7 moves away from or closer to the card seat 2, the rubber block 8 can squeeze the nail gun.

[0026] In this embodiment: when the adjusting sleeve 7 moves on the fixed seat 6, it can squeeze the rubber block 8, causing the straight hole in the rubber block 8 to deform and press against the outside of the nail gun head, thereby facilitating the fixing of the nail gun to the inside of the mounting plate 1.

[0027] The diameter of the side wall of the rubber block 8 gradually increases from the card seat 2 toward the mounting plate 1. The inner side of the adjusting sleeve 7 is provided with a surface that mates with the side wall of the rubber block 8. When the adjusting sleeve 7 moves away from the card seat 2, the surface of the adjusting sleeve 7 that mates with the rubber block 8 presses against the side wall surface of the rubber block 8.

[0028] In this embodiment: when the adjusting sleeve 7 moves away from the card seat 2, the adjusting sleeve 7 can squeeze and deform the side wall of the rubber block 8, so that the head of the nail gun can be fixed inside the straight hole of the rubber block 8, thereby improving the stability of the nail gun inside the mounting plate 1.

[0029] A retaining ring 9 for blocking the rubber block 8 is fixedly connected to the inner side of the end of the adjusting sleeve 7 away from the card seat 2. When the adjusting sleeve 7 approaches the card seat 2, the retaining ring 9 squeezes the rubber block 8 to compress it.

[0030] In this embodiment: when the adjusting block moves toward the card seat 2, the retaining ring 9 can squeeze the rubber block 8, causing the straight hole inside the rubber block 8 to deform, thereby fixing the nail gun inside the straight hole of the rubber block 8 and improving the stability of the nail gun.

[0031] An isolation element 10 is installed between the outer surface of the rubber block 8 and the outer surface of the retaining ring 9.

[0032] In this embodiment, the isolation member 10 can be placed between the rubber block 8 and the retaining ring 9 to reduce the axial deformation of the rubber block 8 during the rotation and movement of the retaining ring 9 towards the card seat 2. It should be noted that the isolation member 10 can be a component similar to a plane bearing that can reduce friction.

[0033] The inner center of the card holder 2 is fixedly connected to a pressure block 11 for pressing a metal gasket in the central groove of the hot melt gasket by several connecting rods. The pressure block 11 has a through hole in the center to accommodate the passage of the nail.

[0034] In this embodiment, the pressure block 11 can press against the metal gasket after the hot melt gasket is installed inside the card holder 2, to prevent the metal gasket from shifting inside the hot melt gasket and to improve the stability of the metal gasket in the hot melt gasket.

[0035] The central axis of the mounting hole of the hot melt gasket and the metal gasket is on the same straight line as the central axis of the connecting hole in the fixing seat 6.

[0036] In this embodiment, by aligning the mounting holes of the hot melt gasket and the metal gasket with the central axis of the connecting hole, the hot melt gasket can be automatically aligned with the nozzle of the nail gun after being installed inside the card holder 2, thereby improving the accuracy of fixing the hot melt gasket by operating the nail gun.

[0037] In use, first insert the nail gun into the rubber block 8, the fixing seat 6, and the mounting plate 1, so that the nozzle of the nail gun protrudes from the outside of the mounting plate 1. Then rotate the adjusting sleeve 7. If the adjusting sleeve 7 is moved away from the mounting plate 1, the inner surface of the adjusting sleeve 7 will abut and press against the rubber block 8, deforming the rubber block 8 and pressing it against the nail gun head. If the adjusting sleeve 7 is rotated towards the mounting plate 1, the retaining ring 9 will squeeze the rubber block 8, deforming it and pressing it against the nail gun head. After fixing the mounting plate 1 to the nail gun head, if the metal gasket and the hot melt gasket separate... First, place the metal pad in the groove in the center of the hot melt pad, aligning the metal pad with the mounting hole in the center of the hot melt pad. Then, place the retainer 2 on top of the hot melt pad and press down on the retainer 2. As the hot melt pad moves into the retainer 2, it will slide along the inclined surface of the clamping block 5 and push the clamping block 5 to retract into the spring support 4. When the hot melt pad is completely pushed into the inside of the retainer 2, the pressure block 11 can abut against and press on the metal pad to fix the metal pad. At this time, the nozzle of the nail gun is automatically aligned with the mounting hole in the center of the hot melt pad and the metal pad, making it more accurate when fixing the hot melt pad by operating the nail gun.

[0038] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
