Taking the fracture of the lower limb of a soldier as an example, the army is equipped with supporting protective equipment including a guard plate and a bandage. When in use, the guard plate is placed on the fracture site of the lower limb, and then the bandage is used to cover and wrap the fracture site to fix and protect it to prevent secondary injury to the fracture site. However, since the outer surface of the lower limb of the human body is not a flat plane, the guard plate cannot fit the soldier's lower limb well to protect the fracture site.
