Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them.

[0026] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; and direct or indirect connections through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model depending on the specific circumstances.

[0027] Example 1:

[0028] In this embodiment, a gun tip, such as Figure 1 and Figure 2 As shown, it includes a copper head body. Specifically, the copper head body includes an integrally formed prism section 1 and an inserting section 2. The prism section 1 includes an end face 3 and multiple side faces 4. The edge of the end face 3 is provided with a chamfered surface 5. The center of the end face 3 is provided with a first nailing hole 6. The first nailing hole 6 is used for nailing operations on a vertical surface. The center of the chamfered surface 5 is provided with a second nailing hole 7. The second nailing hole 7 is used for nailing operations on an inclined surface. One of the side faces 4 is provided with a third nailing hole 8 near the end face 3. The third nailing hole 8 is used for nailing operations on the corner surface of the structure.

[0029] By adopting this structure, by opening the above-mentioned first nail planting hole 6, second nail planting hole 7 and third nail planting hole 8 on three different surfaces, the welding nails can be planted at three different angles, thereby meeting the multi-angle and multi-directional nail planting needs, and can perform convenient, efficient and high-quality nail placement and reinforcement operations on defects in different directions such as vertical surfaces, inclined surfaces or structural corner surfaces, simplifying the operation steps, reducing the difficulty of operation, and making the practicality of the utility model stronger.

[0030] In this embodiment, Figure 1 As shown, the first nail hole 6, the second nail hole 7 and the third nail hole 8 are on the same longitudinal section. When welding defective positions at different angles and directions, there is no need to rotate the welding gun circumferentially to replace the nails, ensuring that the nails are always facing one side of the plastic product, avoiding frequent large-angle adjustments to the direction of the welding gun.

[0031] In this embodiment, the angle between the chamfered surface 5 and the end face 3 is 45°. The 45° chamfered surface 5 makes the angles between the second nail hole 7 and the first nail hole 6 and the second nail hole 7 all 45°. At this time, the welding gun is held horizontally, and the welding nail installed in the second nail hole 7 can remain parallel to the 45° inclined surface. For inclined surfaces greater than or less than 45°, it is only necessary to adjust the direction of the welding gun at an angle less than 45° to adapt to it, thereby avoiding drastically manipulating the direction and angle of the welding gun and increasing the difficulty of operation.

[0032] In this embodiment, the prism segment 1 is a regular quadrangular prism rod, and the edges of the prism segment 1 are chamfered or rounded to avoid safety hazards caused by sharp edges.

[0033] Furthermore, the above-mentioned plug-in section 2 is a cylindrical rod, and the diameter of the above-mentioned plug-in section 2 is the same as the diameter of the inscribed circle of the above-mentioned prism section 1. The above-mentioned plug-in section 2 is used to be plugged and fixed on the welding gun. A step is formed at the position where the above-mentioned plug-in section 2 and the prism section 1 are connected, and the step abuts against the end face 3 of the welding gun, playing a limiting role.

[0034] In this embodiment, a screw hole 9 is provided at the end of the plug-in section 2, and the screw hole 9 serves to connect the welding gun and conduct heat.

[0035] Example 2:

[0036] In this embodiment, a plastic welding gun with multiple holes and multiple angles is used, such as Figure 3 and Figure 4 As shown, it includes a welding gun body, a metal welding nail and a gun head. There are two gun heads. The plug-in sections 2 of the two gun heads are plugged into the front end of the welding gun body side by side and connected to the heating unit of the welding gun body. The two ends of the metal welding nail are respectively plugged into the first nail hole 6 or the second nail hole 7 or the third nail hole 8 of the two gun heads. With such an arrangement, the metal welding nail is installed through the two gun heads for nailing, which prevents the angle of the metal welding nail from being offset, so that multi-angle and multi-directional nailing can be better performed, thereby improving the nailing efficiency and effect.

[0037] It is worth noting that the above-mentioned welding gun body and the internal heating unit are both existing technologies. The heating unit can be a heating transformer or an electric heating tube, and its structure and principle will not be repeated here.

[0038] In this embodiment, the directions of the second nail holes 7 of the two above-mentioned gun heads must be consistent. The above-mentioned gun heads are made of copper, which has high heat transfer efficiency and fast temperature rise, so that the above-mentioned metal welding nails can be quickly heated and melted into the defective surface of the plastic product, thereby implanting the above-mentioned metal welding nails therein, and then withdrawing the above-mentioned welding gun body, so that the above-mentioned metal welding nails can be cooled and retained inside the plastic product.

[0039] In this embodiment, Figure 3 and Figure 4As shown, the metal welding nail includes two plug-in rods 10 and a welding rod 11 connected between the plug-in rods 10. The welding rod 11 is serpentine, straight, V-shaped or M-shaped. When operating the welding vertical surface and inclined surface position, the welding rod 11 is set to a serpentine or M-shaped to form surface reinforcement. When operating the edge position, the welding rod 11 is set to a straight shape to form a line reinforcement. When operating the structural corner surface position, the welding rod 11 is set to a V-shape to fit the angle of the corner, so that the welding rod 11 is supported at the structural corner position. After welding is completed, use a tool to cut off the plug-in rod 10, so that the welding rod 11 remains in the plastic product, thereby increasing the structural strength of the defective position, and then performing a melting and filling treatment of the plastic welding wire on the surface of the position to make up for the surface defects.

Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
