[0035] The gun head structure is located at the head of the nail gun and plays a role in guiding and positioning the nail. It can help the user accurately aim the nail gun at the target position and ensure the accurate firing direction of the nail.

[0036] As Figures 1 to 5 shown, the present utility model embodiment provides a gun head structure, which includes a nail cover 100 and a gun nozzle seat. The nail cover 100 is provided with a nail inlet channel 110 for the nail seat to pass through; the gun nozzle seat 200 is slidably arranged on the nail cover 100, and the gun nozzle seat 200 is provided with a positioning groove 210. When the gun nozzle seat 200 slides into the nail cover 100, the positioning groove 210 is used to position the nail seat. It is easy to understand that through the positioning of the nail inlet channel 110 and the positioning groove 210, the nail seat can be firmly clamped in the positioning groove 210, improving the position accuracy of the nail seat in the gun head structure, making the nail seat not easy to skew, and greatly improving the accuracy of the nail shooting. And this plug-in fit structure improves the stability of the gun nozzle seat 200 in the nail seat.

[0037] Specifically, there is a circumferential limiting structure between the gun nozzle seat 200 and the nail cover 100 to limit the circumferential rotation of the gun nozzle seat 200, that is, after the gun nozzle seat 200 is inserted into the nail cover 100, the gun nozzle seat 200 cannot rotate relative to the nail cover 100 with the central axis as the rotation center, and the gun nozzle seat 200 can be tightly inserted into the nail cover 100 without skew.

[0038] In some embodiments of the present utility model, as Figures 1 to 6 shown, the gun nozzle seat 200 is provided with a guiding portion 220 that extends axially outward along the gun nozzle seat 200. The nail cover 100 is provided with a guiding groove 120. The guiding portion 220 is in plug-in fit with the guiding groove 120 and is placed in the guiding groove 120. This guiding structure enables the gun nozzle seat 200 and the nail cover 100 to have a clear guiding during plug-in, and the stable connection can reduce the relative looseness between the gun nozzle seat 200 and the nail cover 100.

[0039] Furthermore, in some embodiments of the present utility model, as Figures 1 to 6As shown, the guiding part 220 is strip-shaped and has a radially outward arc surface. To facilitate the cooperation between the guiding channel 120 and the guiding part 220, the guiding channel 120 has a corresponding arc surface. The guiding part 220 is inserted into the guiding channel 120, and the outer surface of the guiding part 220 is in close contact with the wall of the guiding channel 120, thereby restricting the circumferential rotation of the nozzle seat 200. In addition, there are grooves on the arc surface of the guiding strip, and the grooves cooperate with other components to fix the nozzle seat 200. Optionally, the guiding part 220 can also be triangular, square, trapezoidal, etc. At this time, the guiding channel 120 can also be formed into a shape adapted thereto.

[0040] In some embodiments of the present utility model, as Figures 1 to 6 shown, the nozzle seat 200 is provided with a positioning part 230. The positioning part 230 is located at one end of the nozzle seat 200 facing the direction of inserting the nail cover 100. Optionally, the positioning parts 230 are distributed at intervals along the transverse direction of the nozzle seat 200. The nail cover 100 is provided with positioning grooves 130. The positioning grooves 130 are arranged inside the nail cover 100 and on the insertion path of the nozzle seat 200. Correspondingly, there are two positioning grooves 130, and the positioning parts and the positioning grooves correspond one by one. In some nail shooting applications, the positioning part 230 is inserted and cooperated with the positioning groove 130 to fix, so as to limit the insertion depth of the nozzle seat 200.

[0041] Specifically, as Figures 1 to 5 shown, the nozzle seat 200 and the nail seat are provided with a guiding structure. The guiding structure is used for guiding the insertion of the nozzle seat 200. When the nozzle seat 200 is inserted into the nail cover 100, its position can be adjusted along the guiding direction.

[0042] In some embodiments of the present utility model, as Figures 1 to 6 shown, the guiding structure includes a guiding inclined surface and a matching inclined surface. The guiding inclined surface is arranged at one end of the nozzle seat 200 facing the direction of inserting the nail cover 100, and the matching inclined surface is arranged on the nail cover 100 and at the insertion and matching position of the nozzle seat 200. The guiding inclined surface includes a first inclined surface 2201 and a second inclined surface 2301. The first inclined surface 2201 is located on the guiding part 220, and the second inclined surface 2301 is located on the positioning part 230. The first inclined surface 2201 and the second inclined surface 2301 are used for guiding the insertion when the nozzle seat 200 is inserted into the nail cover 100.

[0043] In some embodiments of the present utility model, the mating inclined surfaces include a third inclined surface 1201 and a fourth inclined surface 1301. The third inclined surface 1201 is located at the insertion and mating position of the guiding channel 120 and the guiding portion 220, and the fourth inclined surface 1301 is located at the insertion and mating position of the alignment groove 130 and the alignment portion 230. When the nozzle seat is inserted into the nail cap, first, the first inclined surface 2201 abuts against and guides the third inclined surface 1201. When the nozzle seat 200 continues to slide into the nail cap, the second inclined surface 2301 abuts against and guides the fourth inclined surface 1301 for the second time, so that the nozzle seat 200 is fixed in the nail seat.

[0044] Specifically, in some embodiments of the present utility model, as Figure 7 shown, the positioning groove 210 extends along the radial direction of the nozzle seat 200 and communicates with the nail feeding channel 110. The distance between the opposite groove walls of the positioning groove 210 gradually decreases along the side facing the center of the nozzle seat 200. Similarly, the nail feeding channel 110 extends along the radial direction of the nail cap 100, and the opposite groove walls of the nail feeding channel 110 gradually decrease along the side facing the center of the nail cap 100. In addition, the minimum distance between the opposite groove walls of the nail feeding channel 110 is greater than the maximum distance between the opposite groove walls of the positioning groove 210, and the included angle between the groove walls of the positioning groove 210 is greater than the included angle between the groove walls of the nail feeding channel 110. Thus, after the nozzle seat 200 is completely inserted into the nail cap 100, in the vertical projection, the projection area of the positioning groove 210 is located in the projection area of the nail feeding channel 110. Furthermore, during the process of nailing on the nail seat, moving from the nail feeding channel 110 to the positioning groove 210 gradually reduces the moving space of the nail seat, and the nail seat is finally clamped tightly in the positioning groove 210 and is not easily skewed.

[0045] To sum up, the above nail gun head structure shoots nails more accurately and has a more stable structure. By the way of cooperating with the nail feeding channel 110 and the positioning groove 210 to nail, the accuracy of the position of the nail seat in the nail gun head structure is improved. During the continuous nailing process, the nail seat is easily skewed due to impacts such as the striker, which undoubtedly affects the accuracy of nailing. And this nail gun head structure greatly improves the stability and the accuracy of nailing.

[0046] The nail gun according to the embodiment of the present utility model includes the nail gun head structure according to the embodiment of the present utility model.

[0047] The nail gun according to the embodiment of the present utility model, by adopting the nail gun head structure according to the embodiment of the present utility model, the nail gun head structure has the characteristics of firm insertion and not being easily skewed during continuous nailing, improves the accuracy of nailing, and furthermore, the nail gun also utilizes the stable performance of the insertion structure of the nail gun head structure to improve the service life of the nail gun head structure.

[0048] In summary, by improving the cooperation mode between the nail cover 100 and the nozzle base 200, during the nail driving process of the nail base, the nail base is gradually aligned and clamped with the positioning groove 210 through the nail feeding channel 110. During the continuous nail feeding process, the nail base can be more accurately clamped in the positioning groove 210 and is not prone to skew, thereby improving the stability and accuracy of nail driving. In addition, the nail cover 100 and the nozzle base 200 are inserted and cooperated. During nail shooting, the nozzle base 200 can be firmly inserted into the nail cover 100. The stable nozzle base 200 generates less impact force on the nail gun itself during the nail shooting process, reducing the additional wear and damage caused by the skew of the nozzle base 200. This helps to extend the service life of the nail gun and reduce the maintenance and replacement costs.

[0049] In addition, the above has introduced in detail the gun head structure and the nail gun provided by the embodiments of the present invention. In this article, specific examples have been used to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present invention.
