Adaptable screwdriver

摘要

The pins (6-8) protrude beyond an adjustable guide plate (4), and fit against screw heads (5) of widely differing shapes. They can be of different sizes, shapes and materials or alloys.Instead of being spring-loaded, they can be operated by gas, oil or air pressure. The housing with the pins can form a separate module. As a further alternative, they can be controlled electro-magnetically or electronically.
