Abstract

A power driven tool holder for handling apparatus comprises a socket to which a plurality of pincer members are pivotally connected. Each pincer member includes a two-armed lever having a first end where a tool member may be mounted and a second end carrying a cam follower. A cam head common to all pincer members is hydraulically displaceable and is provided with cam tracks individually adapted to the desired displacement of the allocated lever whose cam follower engages the respective cam tracks.
