[0002] With the continuous development of industrial manufacturing technology, aluminum alloys have been widely used in aviation, automobile, construction and other fields due to their advantages such as light weight, high strength and corrosion resistance. However, there are some challenges in the welding process of aluminum alloys, such as high-temperature oxidation, welding porosity, heat-affected zone deformation and other welding defects, which will affect the quality and performance of the welded joints.

[0003] Then during the welding process, the high temperature generated will inevitably cause certain damage to the sunshade lens, and after long-term use, the sunshade lens has to be replaced.

[0037] The protection component 200 includes a fixing component 201 disposed on the front side of the fixing rod 104, and a fastening component 202 disposed inside the fixing component 201;

[0038] The fixing assembly 201 includes a fixing frame 201a fixed to the front side of the fixing rod 104, a pressing frame 201b arranged at one side of the fixing frame 201a, a connecting sleeve 201c arranged inside the pressing frame 201b, a pull rod 201d arranged inside the connecting sleeve 201c, a blocking plate 201e fixed to the outer wall of the pull rod 201d, a spring 201f sleeved on the outer side of the pull rod 201d, and a fixing member 201g arranged at the bottom of the spring 201f;

[0039] The fixing member 201g includes 201g-1 fixed to the bottom of the pull rod 201d, 201g-2 opened inside the pressing frame 201b, and a fixing groove 201g-3 opened at the bottom of 201g-2;

[0040] The fastening assembly 202 includes a guide column 202a arranged inside the clamping frame 201b, a tension spring 202b mounted on the outside of the guide column 202a, a sliding sleeve 202c mounted on the outer wall of the guide column 202a, a fixing plate 202d fixed to the end of the sliding sleeve 202c, a rubber pad 202e fixed to the end of the fixing plate 202d, and a sunshade lens 202f arranged at the end of the rubber pad 202e.

[0041] Specifically, the connecting sleeve 201c is fixedly connected to the fixed frame 201a, the outer wall of the blocking plate 201e is slidably connected to the inside of the connecting sleeve 201c, the bottom end of the spring 201f is fixedly connected to the top of the blocking plate 201e, the top of the spring 201f is fixedly connected to the top of the inner wall of the connecting sleeve 201c, and the length of 201g-1 is smaller than the length of the fixed groove 201g-3.

[0042] Furthermore, the guide column 202a is slidably connected to the sliding sleeve 202c, one end of the tension spring 202b is fixedly connected to one end of the sliding sleeve 202c, and one end of the tension spring 202b is fixedly connected to the inside of the clamping frame 201b.

[0043] The operation process of this embodiment is: first rotate the pull rod 201d to change the angle of 201g-1, then pull the pull rod 201d upwards to gradually pull out the inside of 201g-2, then use the pull rod 201d to flip the clamping frame 201b, and then press the protective plate 202f into the inside of the fixed frame 201a. At this time, the fixed plates 202d on both sides are retracted inward, and the tension spring 202b is squeezed and deformed by the sliding sleeve 202c, which will give the sliding sleeve 202c a force in the opposite direction, and the fixed plate 202d is used to clamp and fix the protective plate 202f.

The characteristics of the rubber pad 202e make the protection plate 202f more firmly fixed, and then the pull rod 201d is used to close the clamping frame 201b, and then the pull rod 201d is rotated to make 201g-1 parallel to 201g-2, and then the bottom of the clamping frame 201b is slowly closed, and then the pull rod 201d is released to allow it to rotate naturally, and then 201g-1 is stuck into the fixed groove 201g-3, and at this time the spring 201f is squeezed, and the reset effect of the spring 201f is used to make 201g-1 tightly stuck in the fixed groove 201g-3 and cannot be easily opened, ensuring that the protective plate 202f is tightly fixed. In addition, this design also facilitates the replacement of the protective plate 202f. Specific embodiment 2
