[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-4 As shown, the present invention proposes a dustproof driving device for a nail gun, including a base 1 and a nail 3, as well as a connecting shell 2, an ejection assembly 4, and a limiting assembly 5: the base 1 is sleeved on one end of the connecting shell 2, and the other end of the connecting shell 2 has a connecting hole 202. A grip 201 is fixed on the outside of the connecting shell 2 for easy gripping by the user. The nail 3 is movably connected to the connecting hole 202. A return spring 103 is provided on the inner side of the base 1. One end of the return spring 103 is connected to the inner side of the base 1, and the other end of the return spring 103 is connected to the connecting shell 2 to limit the position of the connecting shell 2.

[0026] like Figure 1-4 As shown, the ejector assembly 4 is located inside the base 1 and the connecting shell 2 and is movably connected to the nail 3. The ejector assembly 4 includes an ejector pin 402, which is slidably connected to the inside of the connecting shell 2. The ejector assembly 4 also includes an ejector spring 401, one end of which is connected to the inside of the base 1, and the other end of which is connected to one end of the ejector pin 402 for connecting and supporting the ejector pin 402. The other end of the ejector pin 402 is movably connected to an ejector block 403. The connection between the ejector block 403 and the ejector pin 402 is made of rubber. The ejector block 403 is slidably connected to the inside of the connecting hole 202, and the connection is a sealed structure. The other end of the ejector block 403 is movably abutted to the nail 3.

[0027] like Figure 1-3 As shown, a ventilation groove 205 is provided inside the connecting hole 202, and a vent hole 203 is connected through the inner side of the ventilation groove 205. The vent hole 203 is close to the grip handle 201. When the ejector pin 402 pushes out the ejector block 403, it avoids the sealing structure inside the connecting hole 202 causing external air pressure to generate resistance to the ejector block 403 and affect the ejection speed of the nail 3. A filter screen 204 is provided inside the vent hole 203 for dust prevention, so as to prevent dust from affecting the sealing performance of the connection between the ejector block 403 and the connecting hole 202.

[0028] like Figure 1-4As shown, the limiting component 5 is located at the connection between the ejector pin 402 and the connecting shell 2, limiting the position of the ejector pin 402. The limiting component 5 includes a limiting spring 502 and a buckle 503. The ejector pin 402 has a mounting groove 501 on its side. One end of the limiting spring 502 is connected to the mounting groove 501, and the other end of the limiting spring 502 is connected to the buckle 503. The connecting shell 2 has a slot 504 on its side. The buckle 503 and the slot 504 are slidably engaged to limit the relative position of the ejector pin 402 and the connecting shell 2. The base 1 has an insertion hole 101 on its side. A plug 102 is slidably connected in the insertion hole 101 to push out the buckle 503 in the slot 504 and release the connection between the connecting shell 2 and the ejector pin 402.

[0029] In practical use, the nail 3 is connected to the ejector block 403 and pushed into the connection hole 202. The connection hole 202 is aligned with the location where the nail 3 needs to be fired. The base 1 is pressed, and the base 1 slides along the outside of the connecting shell 2 while squeezing the ejector spring 401. The plug 102 is inserted into the insertion hole 101, and the buckle 503 is pushed to squeeze the limiting spring 502 until the buckle 503 leaves the slot 504, leaving a gap between the ejector pin 402 and the connecting shell 2. At this time, the connection limit between the slot 504 and the buckle 503 is released. Under the pushing force of the ejector spring 401, the ejector pin 402 ejects the ejector block 403 and the nail 3, completing the nail firing operation. It is purely mechanically controlled and does not require power to fire the nail 3. It has a simple structure, is easy to carry, consumes no energy, and has low production and use costs.

[0030] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
