[0054] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0055] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0056] It should be noted that the "direction of nail outlet width" in this application text is an appendix. Figure 8 The direction of the x-axis label in the image, "the direction of the nail outlet length" is attached. Figure 8 The direction of the y-axis. The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0057] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0058] During the use of a nail gun, the firing pin reciprocates along the length of the nail outlet under the combined action of the cylinder, piston, motor, and transmission mechanism. The firing pin continuously strikes the nail, ejecting it from the nail gun to achieve nail firing, thus continuously performing the nail firing operation. At the moment the nail is struck by the firing pin, the connecting part is torn, producing debris. If this debris is not discharged, it can easily block the nail outlet, preventing the nail from being smoothly pushed from the receiving cavity into the nail slot, ultimately leading to nail jamming or empty nails. Especially when nailing upwards, the debris falls into the machine, making it even more likely to block the nail outlet. To solve the above problems, this application provides a nail gun.

[0059] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0060] Reference Figures 1-3 As shown, the nail gun in this embodiment may include: a housing 1, a cylinder 2, a piston 3, a firing pin 4, a motor 5, a transmission mechanism 6, a nozzle mounting part 7, a nail clip mounting part 8, and a nail clip 9. Cylinder 2 can be at least partially housed in housing 1; piston 3 can be slidably connected in cylinder 2; firing pin 4 can be connected to piston 3; motor 5 can be housed in housing 1; transmission mechanism 6 can transmit the power of motor 5 and drive firing pin 4 into cylinder 2 to compress gas; nozzle mounting part 7 can be fixedly mounted on housing 1; nail clip mounting part 8 can be connected to nozzle mounting part 7; one end of nail clip 9 can be mounted on nail clip mounting part 8, and the other end can be mounted on housing 1, and nail clip 9 has a receiving cavity; nail clip mounting part 8 can have a nail outlet 81 communicating with the receiving cavity, nail clip mounting part 8 and nozzle mounting part 7 can surround to form a nail firing groove 91 communicating with nail outlet 81, and nail clip mounting part 8 and / or nozzle mounting part 7 can have a slag discharge port 82 communicating with nail firing groove 91 and the external environment. The nail clip 9 has a receiving cavity for mounting a row of nails 90. The row of nails 90 may include nails 901 and connectors 902. The connectors 902 have mounting slots for mounting the nails 902. Multiple connectors 902 are connected in sequence and nails 901 are placed in the mounting slots to form a row of nails. The nozzle mounting part 7 is fixedly mounted to the outer casing 1 by bolts, screws and other fasteners.

[0061] By setting a slag discharge port 82, the size of which is usually larger than the size of debris and broken nails, when debris or broken nails fall into the machine, they can easily fall out from the slag discharge port 82, reducing the risk of clogging the nail outlet 81, thereby greatly reducing the occurrence of nail jamming and empty nail problems and improving the user experience.

[0062] Specifically, to facilitate slag removal, the slag discharge port 82 in this embodiment is disposed on the nail clamp mounting portion 8 and at least partially exposes the nozzle mounting portion 7 and the outer casing 1. Of course, in other embodiments, the slag discharge port 82 may also be disposed on the inner wall of the nozzle mounting portion 7; or, in other embodiments, the nail clamp mounting portion 8 is provided with a first portion and the nozzle mounting portion 7 is provided with a second portion, and when the nail clamp mounting portion 8 is mounted on the nozzle mounting portion 7, the first portion and the second portion are disposed adjacent to each other to form the slag discharge port 82.

[0063] Specifically, refer to Figures 6-8 and combined Figure 2 , Figure 3 As shown, the nail clip mounting part 8 in this embodiment may include a main body 801 and an extension part 802 disposed on the main body 801 and extending outward. The extension part 802 may be disposed in the nozzle mounting part 7, the main body 801 may be mounted on the nozzle mounting part 7, and the slag discharge port 82 may be disposed on the main body 801 and the extension part 802. Of course, this application is not limited to this. In other embodiments, the slag discharge port 82 may be disposed only on the main body 801 or only on the extension part 802. As long as it facilitates slag discharge through the slag discharge port 82, it is within the protection scope of this application.

[0064] Furthermore, referring to Figures 5-8 and combined Figure 2 , Figure 3 As shown, the slag discharge port 82 in this embodiment may include a first groove 821 and a second groove 822 located below the first groove 821. The first groove 821 connects to the nail gun groove 91, and the second groove 822 connects the first groove 821 to the external environment. The first groove 821 may be disposed on the extension 802, and the second groove 822 may be disposed on the main body 801 and may partially expose the nozzle mounting part 7 and the outer shell 1. According to this design, the first groove 821 can better receive debris or broken nails and other slag materials impacted from the nail gun groove 91 during nail firing, preventing slag materials from accumulating in the nail gun groove 91; the second groove 822 can be more open to the outside environment, facilitating smoother discharge of slag materials. Of course, this application is not limited to this, and in other embodiments, the second groove 822 may be fully exposed above the nozzle mounting part 7 and the outer shell 1.

[0065] Preferably, refer to Figure 7 , Figure 8As shown, the dimension of the second groove 822 along the length of the nail outlet 81 can be larger than the dimension of the first groove 821 along the length of the nail outlet 81. As shown in the main structural view of the nail clamp mounting part, the slag discharge port 82 can be "L"-shaped. According to this design, during the discharge of debris and broken nails, the slag falls into the first groove 821 and then into the second groove 822 before being discharged. The narrower design of the first groove 821 maintains the limiting effect of the nail's trajectory on the nail 901 while maximizing the efficiency of slag discharge; the wider design of the second groove 822 provides ample space for slag discharge, ensuring smooth discharge and reducing the risk of slag blockage in a single narrow groove. Of course, this application is limited to this; in the main structural view of the nail clamp mounting part, the slag discharge port 82 in other embodiments is "V"-shaped or "|"-shaped, etc. In other embodiments, the dimension of the second groove 822 along the length of the nail outlet 81 can also be equal to the dimension of the first groove 821 along the length of the nail outlet 81.

[0066] Reference Figures 6-8 As shown, in this embodiment, the first groove 821 is along the width direction of the nail outlet 81 (refer to...). Figure 8 The dimension of the first groove 821 (in the direction indicated by the x-axis) can be greater than the width of the nail outlet 81. It should be noted that since the dimension of the nail outlet 81 needs to be larger than the dimensions of the nails 901 and connectors 902 in the nail pack 90, when the dimension of the first groove 821 along the width direction of the nail outlet 81 is greater than the width of the nail outlet 81, it facilitates the discharge of slag and provides storage space for slag falling from the nail injection groove 91 into the first groove 821. By temporarily containing the slag falling into the first groove 821, the risk of clogging the nail injection groove 91 and the first groove 821 is reduced. Of course, in other embodiments, the dimension of the first groove 821 along the width direction of the nail outlet 81 can be equal to the width of the nail outlet 81.

[0067] To facilitate the accumulation of some slag on the first groove 821, thereby reducing the impact force generated by the slag directly impacting the slag discharge port 82 during nail shooting, reducing local wear, and extending the structural life, refer to Figures 6-8 As shown, in this embodiment, the first groove 821 is arranged in a horizontal direction.

[0068] Preferably, to facilitate the impact of the slag material from the nail gun groove 91 into the first groove 821, refer to Figures 6-8 and combined Figure 3 As shown, in this embodiment, the extension 802 may be provided with a guide surface 8021 connected to the side wall of the first groove 821 away from the outer casing 1. From the firing pin 4 to the nozzle mounting part 7, the distance between the guide surface 8021 and the center line L1 of the nail outlet 81 can gradually decrease. According to this design, the slag can move with the surface of the guide surface 8021 and fall into the first groove 821.

[0069] Reference Figures 6-8 and combined Figure 2 As shown, in this embodiment, the nail clip 9 can be inserted into the main body 801. An abutment platform 8011 can be provided on the inner wall of the main body 801, and the nail clip 9 can abut against the abutment platform 8011. Based on this design, one end of the nail clip 9 can be installed in the nail clip mounting part 8. The design of the abutment platform 8011 limits the depth to which the nail clip 9 extends into the main body 801.

[0070] Because during the impact of the firing pin 4 on the nail 901, the connecting piece 902 will be broken into fragments, and these fragments will continue to move forward along the direction of the firing pin 4. Therefore, referring to... Figures 1-3 As shown, in this embodiment, the slag discharge port 82 can be connected to the end of the nail gun groove 91 away from the outer shell 1, which can facilitate the discharge of debris or broken nails and other slag materials that are struck by the firing pin 4 to the front end of the nail gun groove 91 (i.e., the end away from the outer shell 1); at the same time, it can minimize the problem of the nail discharge port 81 being blocked due to the disordered displacement of the slag material in the nail gun groove 91 caused by the inertia of the firing pin 4 retracting into the cylinder 2.

[0071] Reference Figure 9 , Figure 10 and combined Figure 2 As shown, to facilitate the insertion of the nail clip mounting part 8 onto the nozzle mounting part 7, a first mounting post 8012 is provided on the outer side wall of the nail clip mounting part 8 away from the outer casing 1 in this embodiment, and a first mounting groove 71 that mates with the first mounting post 8012 is provided on the inner side wall of the nozzle mounting part 7. Specifically, the first mounting post 8012 is provided on the main body part 801. According to this design, the first mounting post 8012 can be inserted into the first mounting groove 71 in the horizontal direction, which facilitates the installation and removal of the nail clip mounting part 8, and thus facilitates the installation and removal of the nail clip 9.

[0072] Of course, this application is not limited to this. In other embodiments, the nail clip mounting portion 8 has a first mounting groove 71 on its outer side wall away from the outer casing 1, and the nozzle mounting portion 7 has a first mounting post 8012 that mates with the first mounting groove 71. Alternatively, the nail clip mounting portion 8 has a first mounting post 8012 on its outer side wall facing the outer casing 1, and the nozzle mounting portion 7 has a first mounting groove 71 that mates with the first mounting post 8012 on its inner side wall; or, the nail clip mounting portion 8 has a first mounting groove 71 on its outer side wall facing the outer casing 1, and the nozzle mounting portion 7 has a first mounting post 8012 that mates with the first mounting groove 71.

[0073] Preferably, in this embodiment, a second mounting post 8013 is provided on the outer side wall of the nail clip mounting part 8 opposite to the first mounting post 8012 (i.e., facing the outer shell 1), and a support part is provided on the inner side wall of the nozzle mounting part 7. The second mounting post 8013 abuts against the support part. When the first mounting post 8012 is inserted into the first mounting groove 71 in the horizontal direction, the end of the nail clip mounting part 8 facing the outer shell 1 can abut against the nozzle mounting part 7. After the second mounting post 8013 is provided, the contact area between the nail clip mounting part 8 and the nozzle mounting part 7 is reduced, which can reduce the frictional resistance between the nail clip mounting part 8 and the nozzle mounting part 7, so as to better insert the nail clip mounting part 8 into the nozzle mounting part 7. Of course, this application is not limited to this. In other embodiments, a second mounting post 8013 is provided on the inner side wall of the nozzle mounting part 7, and the second mounting post 8013 abuts against the outer side wall of the nail clip mounting part 8 facing the outer shell 1.

[0074] Optionally, to prevent the second mounting post 8013 on the nail clip mounting part 8 from sagging, the support part in this application may be provided with a second mounting groove that mates with the second mounting post 8013. When the second mounting post 8013 is provided on the support part of the nozzle mounting part 7, the outer wall of the nail clip mounting part 8 facing the outer shell 1 is provided with a second mounting groove that mates with the second mounting post 8013.

[0075] Preferably, to further reduce assembly resistance, the second mounting post 8013 in this embodiment may be provided with a chamfered portion 80131. Of course, in other embodiments, the first mounting post 8012 may also be provided with a chamfered portion 80131, or both the first mounting post 8012 and the second mounting post 8013 may be provided with a chamfered portion 80131.
