Scanning electron microscope Wien filter instrument assembly pieces support structure having body space support pieces receiving/positioning with moving elements pushed/adapted contacting and pushing pieces plugging support structure.

摘要

The support structure assembly mechanism (A) has a body space with support structure and pieces adapted to receive and position the body comprising an external structure. There are a number of mobile elements mounted on the outer structure which move in a direction when pushed and adapt to make contact with the outer pieces. There is a gravity acting mechanism on the moving elements acting in the direction of the pushing pieces and plugging with the support structure.
