We design a new electric drill for business, personal and industrial people, on which there are best craft, top property and quality. Thus, it can ensure people work efficiently. When people are using electric drill, traditional electric drill always leads to the problems of sidesliping, hitting inaccurately and destroying surface, and so on. Aiming at this problem, we research and improve the electric drill. Compared with traditional electric drill, we add a device of angle adjustment to the electric drill we design. People can adjust the device to solve above problem more conveniently.
