Universally usable propagation piston - has fixture made up of two wire or spring components forming tension area between both ends of tube

摘要

The fixture device comprises at least two wire or leaf-shaped spring components (12,12'), which at their one end are held in the end piece (7) of the tube (3) and with their other end in the direction of the proximal end of the tube strive to push away from one another, forming a tension area. Around the spring components and along them a tension ring (11) or a tension socket is arranged. The internal dia. of the tension ring or tension socket is smaller than the outer dia. of the cover curve of the spring components in at least the largest part of the tension area. The tension ring or the tension socket in at least one position presses the spring components against their spring force in the direction of the tube (3), and so the distal end of the propagation casing (9) is clampable between the spring components and the tube. ADVANTAGE - Provides a simple and secure clamping of the propagation casing.
