A gripping device comprises a support body (2) within a sleeve (8), with
the sleeve being mounted around the body for relative translational
movement along a common axis thereof. A plurality of gripping elements
(10, 12) are pivotally mounted in the body (2), the elements having lever
arms (20, 22) projecting laterally from the boundary of the body.
Translational movement of the sleeve (8) relative to the body (2) causes
working engagement of the sleeve with the gripping element lever arms
(20, 22), and movement of the lever arms to pivot the elements (10, 12)
and close the elements around an item captured therebetween. Normally,
the pivotal axes for the gripping elements (10, 12) are disposed within
the support body (2), with the elements themselves projecting axially
from an end thereof. The pivotal axes are normally substantialy parallel,
and indeed the gripping elements may all be mounted for pivotal movement
about the same common axis (18). The pivotal axis or axes will usually be
perpendicular to the common axis of the support body and sleeve, but
there may be applications in which a different angular relationship
between these axes will be used.
