A screwdriver design for military enthusiasts has special use experience and convenience. The batch head is stored in the magazine. The process of replacing the batch head is like the loading and firing process of firearms. In this process, the batch head does not deviate from the main body to prevent the loss of the batch head.

A conceptual design during the university, the second prize of the 2017 industrial design competition, now looks very immature, re-render it and send it out to share it. At that time, the hand board was made, but the function of the hand board was not perfect due to the complex structure and processing error. Generally speaking, this is an ideal design, which is too complicated and less reliable as a tool. Toys may be more suitable if it is positioned as a collection; friends who like it remember to give me a compliment and let me know O(∩_∩)O
