[0035] In the description of the present invention, reference to terms such as "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the exemplary expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0036] The installation of fixed brackets (such as pipe brackets, U-shaped brackets, and card brackets) is a common and critical task during construction and maintenance. Traditional methods of installing fixed brackets typically require operators to manually position the brackets in a predetermined location and then secure them with a nail gun. This process presents the following major issues:

[0037] 1. Inconvenient operation: The operator needs to hold the fixed code piece with one hand and operate the nail gun with the other hand, which not only increases the difficulty of operation, but also easily causes the position of the fixed code piece to shift, affecting the installation quality.

[0038] 2. Poor safety: Especially in high-altitude working environments, the operator's hands cannot simultaneously fix the code parts and operate the nail gun, which increases the operational risks and may lead to safety accidents.

[0039] 3. Limited scope of application: The existing nail gun nozzle design is relatively simple and difficult to adapt to fixed code parts of different specifications and shapes. As a result, the nozzle needs to be frequently replaced in actual application, which reduces work efficiency.

[0040] Based on the above analysis, the market urgently needs a new nozzle design that can solve the above problems to improve the convenience, safety and adaptability of fixed code parts installation.

[0041] For this reason, Figure 1 and Figure 2 As shown, a gun nozzle proposed by the present invention includes a main body 100 and a positioning portion 200 integrally connected to the main body 100, wherein the main body 100 is hollow tubular, the positioning portion 200 is integrally connected to the outer peripheral wall of the main body 100, and the center line of the positioning portion 200 coincides with the center line of the main body 100. Specifically, in the circumferential direction of the positioning portion 200, the positioning portion 200 has a first outer diameter and a second outer diameter that are different, so as to perform alignment installation of the code piece. In some applications, the code piece and the positioning portion 200 are snap-fitted together, which not only enables the code piece to be more securely mounted on the gun nozzle, but also facilitates quick disassembly and replacement, thereby improving the flexibility and convenience of operation. Moreover, the snap-fit ​​design can also provide a better positioning effect during the installation process, thereby preventing the code piece from being offset during the installation process.

[0042] The locating portion 200 is designed to be mounted on the gun nozzle and can be rotated to select a specific mounting position with the locating portion 200. The user can then hold the nail gun with one hand to operate the nail gun and nail the code piece into the building. The special outer diameter design of the locating portion 200 enables the code piece to be firmly mounted on the gun nozzle, and the operator can operate the nail gun with one hand, which greatly improves the convenience and safety of operation and is particularly suitable for complex environments such as high-altitude operations. Secondly, the design of the integral alignment of the code piece with the gun nozzle after the code piece is inserted avoids the possible offset or misalignment that may occur when the code piece is positioned manually and then nailed into the code piece with the gun nozzle, thereby ensuring the convenience and accuracy of fixing the code piece on the building. In addition, the locating portion 200 has different first and second outer diameters in the circumferential direction. This structural design enables different types of code pieces to be accurately installed in the gun nozzle, broadens the scope of application of the nail gun, reduces the frequency of replacing the gun nozzle, and further improves work efficiency. Overall, it not only improves the installation quality and safety, but also enhances the versatility and adaptability of the equipment.

[0043] It is easy to understand that in the case of different outer diameter positioning, different opening installation distances can be provided for the positioning of the code piece, thereby achieving different fastening forces between the code piece and the positioning portion 200. For example, when the first outer diameter is smaller than the second outer diameter, the fastening force generated when the code piece of the same specification is installed on the first outer diameter is smaller, while the fastening force generated when installed on the second outer diameter is larger, and it is less likely to loosen during the movement of the nail gun.

[0044] In some applications, when the code piece is inserted into the gun nozzle, it is aligned with the end of the body 100. For example, the code piece and the end of the body 100 are rotated together. In some applications, a screw clearance hole is set in the center of the code piece. After the code piece is pressed against the building, it can be fixed on the building after the nail is shot out from the body 100.

[0045] Refer again Figure 1 and Figure 2In some embodiments of the present invention, the peripheral wall of the positioning portion 200 includes two first positioning walls 201 and two second positioning walls 202. The two first positioning walls 201 are arranged opposite to each other, and the two second positioning walls 202 are arranged opposite to each other. The distance between the two first positioning walls 201 is different from the distance between the two second positioning walls 202. In addition, the nozzle can better adapt to code pieces of different shapes and sizes, ensuring that they can be accurately positioned and installed during the installation process, avoiding installation quality problems caused by inaccurate positioning. Optionally, the first positioning wall 201 and the second positioning wall 202 are both planar structures. The planar structure not only simplifies the manufacturing process and reduces production costs, but also provides more stable support, making the code pieces more stable during installation and reducing the possibility of shaking and offsetting. For example, the axial cross-section of the positioning portion 200 is a special polygon. This polygon is symmetrical in each radial direction so that the code pieces can be centrally arranged after being fixed, and the distance between two parallel sides of different polygons is different.

[0046] In some embodiments, the first positioning wall 201 and the second positioning wall 202 are connected by a right-angle transition or a slope transition. Figure 2 As shown, an arc-shaped transition wall 203 is provided between the first positioning wall 201 and the second positioning wall 202, which facilitates the smooth rotation of the code piece, so as to ensure that the code piece is rotated into the corresponding first positioning wall 201 or second positioning wall 202, thereby finding the most suitable position for the code piece to be installed on the positioning portion 200, further improving the convenience and accuracy of the operation. Figure 1 In some embodiments of the present invention, a guide wall 204 is provided at the edge of the end face of the positioning portion 200 to guide the insertion of the code element. This helps guide the code element to be inserted quickly and accurately into the surrounding wall of the positioning portion 200, reducing the operator's adjustment time and difficulty during installation and improving work efficiency. Furthermore, the guide wall 204 can protect the surface of the code element, preventing scratches or damage during installation.

[0047] In some embodiments, the positioning portion is a single-layer structure (not shown). In some embodiments of the present invention, the positioning portion 200 is a multi-layer structure that gradually tapers toward one end of the body 100. This multi-layer design allows the nozzle to adapt to different sizes of code pieces, eliminating the need for frequent nozzle replacement, greatly improving the versatility and adaptability of the device.

[0048] In other embodiments of the present invention, the cross-section of the positioning portion in the axial direction is elliptical (not shown). This elliptical cross-section allows the nozzle to better adapt to various shaped components, particularly non-circular ones, ensuring accurate positioning and securement during installation. Furthermore, compared to the planar first and second positioning walls, the elliptical shape allows for stepless adjustment of the mounting distance between the components, thereby enabling optimal selection of the appropriate tightening force and ensuring a more secure fit of the components on the nozzle.

[0049] The gun head assembly according to the embodiment of the present invention includes a gun nozzle according to the embodiment of the present invention. By adopting a gun nozzle according to the embodiment of the present invention, the code piece can be installed on the positioning part 200 after being inserted into the gun nozzle, and can be further rotated to select a specific installation position with the positioning part 200. Then, the user can hold the nail gun with one hand to operate it to nail the code piece into the building; wherein, the special outer diameter design of the positioning part 200 enables the code piece to be firmly installed on the gun nozzle, and the operator can operate the nail gun with one hand, which greatly improves the convenience and safety of operation, and is particularly suitable for complex environments such as high-altitude operations. Secondly, the design of the code piece being aligned with the gun nozzle after being inserted avoids the traditional manual positioning of the code piece and then using the gun nozzle to align it. The deviation or misalignment that may occur when nailing the code pieces into the gun can be avoided, thereby ensuring the convenience and accuracy of fixing the code pieces to the building. In addition, the positioning portion 200 has a first outer diameter and a second outer diameter that are different in the circumferential direction. This structural design enables different types of code pieces to be accurately installed in the gun nozzle, broadens the application range of the nail gun, reduces the frequency of replacing the gun nozzle, and further improves work efficiency. Overall, this improved gun head assembly not only improves the installation quality and safety, but also enhances the versatility and adaptability of the equipment, meeting the needs for efficient, safe and convenient operation during construction and maintenance.
