Therefore, in the prior art, the cost of materials and time for learning the manufacture of the cable head are very high. In the training process, the training personnel inevitably need to carry out a series of operation procedures such as cutting and peeling on the cable by hands in actual operation because the training personnel contact the cable head for the first time, certain operation danger is provided, and the training personnel can cut hands or collide other parts when the tool is not used properly or the operation is not standard.
