[0002] Magnesium alloys are alloys composed of magnesium as a base and other elements added. Their characteristics include: low density, high strength, high elastic modulus, good heat dissipation, good vibration damping, greater impact load capacity than aluminum alloys, and good resistance to corrosion from organic substances and alkalis. The main alloying elements include aluminum, zinc, manganese, cerium, thorium, and small amounts of zirconium or cadmium. Magnesium-aluminum alloys are the most widely used, followed by magnesium-manganese alloys and magnesium-zinc-zirconium alloys. They are mainly used in the aerospace, transportation, chemical, and rocket industries.

[0003] When processing magnesium alloy parts, they need to be fixed. For example, patent CN114714269A describes a fixing device for aluminum-magnesium alloy processing, including a processing plate, a base plate, a screw, a lower clamp, an upper clamp, a lower clamp block, and an upper clamp block.
