[0022] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Example 1: Please refer to Figures 1 to 6 This utility model provides a technical solution: a flame cutting device for steel pipe production and manufacturing, including: a handheld spray gun 1, a mounting base 2 fixed on the surface of the handheld spray gun 1, a frame 3 provided on the surface of the mounting base 2, an installation groove 4 opened on the inner wall of the frame 3, a tempered protective glass 5 movably inserted into the installation groove 4, and the frame 3 having a "U" shaped plate structure.

[0024] In actual use, the tempered protective glass 5 is installed into the mounting groove 4 opened on the inner wall of the frame 3. The frame 3 is fixed to the handheld spray gun 1 by the mounting base 2. When the operator uses the handheld spray gun 1 to cut the steel pipe, the flying sparks are blocked by the tempered protective glass 5, thus protecting the operator from being burned by the sparks. At the same time, the tempered protective glass 5 has good light transmission and will not obstruct the operator's observation of the working position. The mounting base 2 and the frame 3 are set around the tempered protective glass 5, which can protect the tempered protective glass 5 and prevent it from being broken.

[0025] Example 2: Based on Example 1, in order to facilitate the assembly and disassembly of the tempered protective glass 5, two sets of insertion slots 6 are provided on the surface of the mounting base 2. The insertion slots 6 are rectangular slot structures. Insertion blocks 7 are fixed on the two vertical plates of the frame 3. The insertion blocks 7 are rectangular block structures. The two sets of insertion blocks 7 are movably inserted into the two sets of insertion slots 6 respectively. Limiting holes 8 are provided on the surface of the mounting base 2. The limiting holes 8 are in communication with the insertion slots 6. Limiting hole mounting grooves 9 are provided on the surface of the insertion blocks 7. The limiting hole mounting grooves 9 are rectangular slot structures. One end of the limiting block 10 is movably inserted into the limiting hole mounting groove 9. The other end of the limiting block 10 is movably inserted into the limiting hole 8. A limiting spring 11 is fixed at one end of the limiting block 10 that extends into the limiting hole mounting groove 9. The other end of the limiting spring 11 is fixed on the inner wall of the limiting hole mounting groove 9. An inclined surface is provided at the end of the limiting block 10 that extends into the limiting hole 8.

[0026] When the tempered protective glass 5 needs to be replaced or cleaned, it needs to be disassembled and reassembled. To remove the tempered protective glass 5, simply insert your finger into the limiting hole 8 and press down, causing the limiting block 10 to be pushed out of the limiting hole 8 and fully retracted into the limiting hole mounting groove 9. Then, the insertion block 7 can be disengaged from the insertion groove 6, allowing the frame 3 to be removed from the mounting base 2. Afterward, pull the tempered protective glass 5 out of the mounting groove 4 along the opening direction of the frame 3 to complete the removal of the tempered protective glass 5. To install the tempered protective glass 5, simply insert the tempered protective glass 5... Insert the small piece into the mounting slot 4, and then insert the plug 7 back into the plug slot 6. As the plug 7 is inserted back into the plug slot 6, the inner wall of the plug slot 6 slides over the inclined surface of the limiting block 10, thereby pushing the limiting block 10 completely into the limiting hole mounting slot 9. At this time, the limiting spring 11 is compressed. After the plug 7 is fully inserted into the plug slot 6, the limiting hole 8 and the limiting hole mounting slot 9 are aligned. Then the limiting spring 11 pushes one end of the limiting block 10 back into the limiting hole 8, thus completing the installation of the frame 3 and the mounting base 2, thereby realizing the installation of the tempered protective glass 5.

[0027] Example 3: Based on Example 2, in order to achieve more stable operation of the handheld spray gun 1, a handle 12 is fixed on the surface of the frame 3.

[0028] After the frame 3 and tempered protective glass 5 are installed on the handheld spray gun 1, the center of gravity of the handheld spray gun 1 shifts towards the frame 3 and tempered protective glass 5. Therefore, in order to operate the handheld spray gun 1 more stably, a handle 12 is set on the frame of the frame 3. The handle 12 is located on the part of the frame 3 away from the handheld spray gun 1. When operating the handheld spray gun 1, one hand holds the handheld spray gun 1 and the other hand holds the handle 12, which can achieve a more stable grip on the handheld spray gun 1.

[0029] In actual use, the tempered protective glass 5 is installed into the mounting groove 4 opened on the inner wall of the frame 3. The frame 3 is fixed to the handheld spray gun 1 by the mounting base 2. When the operator uses the handheld spray gun 1 to cut the steel pipe, the flying sparks are blocked by the tempered protective glass 5, thus protecting the operator from burns. At the same time, the tempered protective glass 5 has good light transmission and will not obstruct the operator's observation of the work position. The mounting base 2 and the frame 3 are set around the tempered protective glass 5, which can play a role in protecting the tempered protective glass 5. The tempered protective glass 5 provides protection against breakage. When it needs to be replaced or cleaned, it must be disassembled. To remove the tempered protective glass 5, simply insert your finger into the limiting hole 8 and press down, causing the limiting block 10 to be pushed out of the limiting hole 8 and fully retracted into the limiting hole mounting groove 9. Then, the insertion block 7 can be disengaged from the insertion groove 6, allowing the frame 3 to be removed from the mounting base 2. Finally, the tempered protective glass 5 can be pulled out of the mounting groove 4 along the opening direction of the frame 3 to complete the removal of the tempered protective glass 5. When installing the tempered protective glass 5, simply insert the tempered protective glass 5 into the mounting groove 4, and then insert the plug 7 back into the plug groove 6. As the plug 7 is inserted back into the plug groove 6, the inner wall of the plug groove 6 slides over the inclined surface of the limiting block 10, thereby pushing the limiting block 10 completely into the limiting hole mounting groove 9. At this time, the limiting spring 11 is compressed. After the plug 7 is fully inserted into the plug groove 6, the limiting hole 8 aligns with the limiting hole mounting groove 9, and the limiting spring 11 pushes one end of the limiting block 10 back into the limiting position. The frame 3 and the mounting base 2 can be installed through hole 8, thereby realizing the installation of tempered protective glass 5. After the frame 3 and tempered protective glass 5 are installed on the handheld spray gun 1, the center of gravity of the handheld spray gun 1 shifts towards the frame 3 and the tempered protective glass 5. Therefore, in order to operate the handheld spray gun 1 more stably, a handle 12 is set on the frame of the frame 3. The handle 12 is located on the part of the frame 3 away from the handheld spray gun 1. When operating the handheld spray gun 1, hold the handheld spray gun 1 with one hand and hold the handle 12 with the other hand to achieve a more stable grip on the handheld spray gun 1.
