Hand protection is one of the most delicate and compact organs in human organs. It consists of 27 bones, which accounts for 1/4 of the total number of bones, and the distribution and tissue of muscles, blood vessels and nerves are extremely complex. The length of each centimetre of capillary on the fingertips can reach several meters and thousands of nerve endings. These fine neural networks enable us to detect cold, heat, pain and so on in a few microseconds, and even feel that the amplitude of the vibration is only as small as the hair of the hair. From the day of birth, the hands did not stop activities, and when the end of life, the average hand can move 250 million times. However, we often ignore the importance of hand and neglect the proper protection of it, so that in all kinds of work injury accidents, hand injury accidents account for 20%. Therefore, it is very necessary to choose and use protective appliances correctly. Traumatic injuries such as hand injuries are caused by mechanical causes of injury to the bones, muscles, or tissue and structure, from severe finger, bone crack to slight skin injury. If a tool with sharp parts is used, a large machine or instrument with a knife and tip can be manipulated to cause a cut of a hand, such as a hand, a spindle, a nail, a chisel, a chisel, a wire and so on. The hand is sprained, pressed and even rolled out of the finger.
