[0002] With the development of my country's industry and the advancement of science and technology, my country's demand for iron ore has gradually increased. In the process of iron ore mining, it is often necessary to blast the iron ore, and the blasting of iron ore is generally accompanied by the splashing of gravel. Although these gravels are small in size, they will splash at a very high speed during blasting. If they splash on workers, it will undoubtedly cause great personal injury to the workers. Therefore, protective devices are generally required in iron ore blasting. At present, there are many kinds of mine blasting protection devices. Among them, handheld blasting protection devices play an important role in assisting workers in mine blasting because of their small size and easy to carry characteristics.

[0003] For example, a Chinese utility model patent with authorization announcement number CN207622628U discloses a lightweight handheld protective plate for coal mine blasting, including a protective plate body and a frame, a fixed base is fixedly installed at the bottom of the protective plate body, and rollers are arranged on both sides of the fixed base, the two sides of the protective plate body are connected to the support rod through a rotating shaft, and rollers are fixedly installed at the bottom of the support rod, the protective plate body is installed on the outside of the frame, and partitions are connected to both sides of the frame, sound-absorbing cotton is installed in the middle of the frame, and the top of the frame is connected to the handle through the protective plate body, a fixed block is arranged below the handle, and a handrail is installed below the fixed block, the right side of the fixed block is connected to the bottom plate through the protective plate body, and a groove is arranged above the protective plate body.

[0004] The above-mentioned prior art only relies on the protective plate body to block the flying stones, and cannot effectively buffer the impact force of the flying stones. When the flying stones fly at a faster speed, the impact force of the flying stones on the protective plate is relatively large, which can easily injure the workers' arms, and the protective effect is poor.
