[0028] Specifically, by setting up a magnetic strip 1, during welding, the magnetic strip 1 is attracted to the vicinity of the welding position. The bearing strip 22 is hinged, and the receiving ring 31 is adjusted to a suitable angle and then fixed by a fastener, so that the receiving ring 31 is located below the weld position, catching falling sparks and reducing safety hazards.

[0029] In some feasible methods, the magnetic strip 1 is a strip magnet used to adhere to the welding position. To reduce damage to the magnetic strip 1, a rectangular plate is fixedly installed on the outside of the magnetic strip 1 as a rigid support. A removable protective sleeve is provided on the outside of the magnetic strip 1 to reduce impact damage.

[0030] Both the connecting strip 21 and the bearing strip 22 are rectangular strips.

By setting multiple hinged magnetic blocks 11 to form a magnetic strip 1, it is easy to adapt to different surfaces, improve the adsorption force, and make the hinge axis of the magnetic block 11 perpendicular to the hinge axis of the bearing strip 22. This makes it easy for the magnetic strip 1 to maintain rigidity in the support direction of the bearing ring 31, which is convenient for fixing the position of the fireproof bag 32.

[0034] Furthermore, the magnetic block 11 includes a connecting plate 12 and a strong magnet 13, the connecting plate 12 being hinged to each other, and the strong magnet 13 being fixedly installed on the connecting plate 12.

[0037] In some feasible methods, a flexible protective sleeve is provided on the outside of the magnetic strip 1, which can be made of flexible materials such as silicone or cloth to reduce the impact damage to the strong magnet 13. At the same time, by removing the flexible protective sleeve, it is easy to handle impurities such as iron filings that have been adsorbed.

[0038] As a specific embodiment of the magnetic welding fireproof device provided in the application, the connecting strip 21 includes a bearing part 211, the bearing part 211 is rotatably connected to an adjusting part 212, and the adjusting part 212 is connected to the bearing strip 22.

[0039] It should be understood that by providing the rotatable adjustment part 212, the receiving ring 31 can be rotated to other positions for use, thereby improving the flexibility of the adjustment of the receiving ring 31 and making it easier to use.

[0040] Furthermore, the adjusting part 212 is fixedly connected to a rotating shaft 213, and the rotating shaft 213 passes through the bearing part 211 and is threadedly connected to a fastening nut 214.

[0041] It should be understood that by setting the rotating shaft 213 and the fastening nut 214, it is convenient to fix the position of the adjusting part 212 after rotation.

[0042] Furthermore, both the bearing part 211 and the adjusting part 212 are provided with gear discs 215 at their rotatable connection positions, and the two gear discs 215 mesh after the fastening nut 214 is tightened.

[0043] It should be understood that by setting the meshing toothed disc 215, it is further convenient to fix the position of the adjusting part 212 after rotation.
