Dustproof Electric Drill The Improved Design

In view of the existing electric impact drill development present situation, analyses and explores the defects of electric impact drill and appreciation of space. On this basis, this article mainly from the electric impact drill of man-machine engineering, safety, improvement and innovation design modelling, dust, etc. On man-machine engineering, and redesign the handle, increase the friction force of handle and prevent the long finger slipped from the handle under the operation. In terms of security, you have lots of potential dangerous use percussion drill, such as bit of rupture, flying debris, leakage, etc. According to the possibility of mechanical bruising, design the dust cover, to prevent the splash damage human body. Keep certain distance insulation on structure design, material also want to choose insulation material to prevent electric shock.
