摘要

#CMT# #/CMT# The ring spanner (1) has a handgrip (2) with a connected engagement device (3) for a tension unit such as a hexagonal nut and which comprises a round engagement disk with a groove-shaped recess (4) which extends with surfaces for engagement (8,9) with a tension (5) unit. The disk and the handgrip are provided with collaborating connecting devices for rotatable connection of the disk to the handgrip. Securing components are provided for securement of the disk in at least a suitable staste in relation to the handgrip. #CMT# : #/CMT# Provision is made for a collection of ring spanners, in which the engagement surfaces are spaced differently. The hexagonal nut grips with one end with a left-hand scerw thread on a screw stem (7). By rotation of the nut the screw stems are drawn to each other. #CMT#USE : #/CMT# As a ring spanner for engagement with a hexagonal nut. #CMT#ADVANTAGE : #/CMT# The spanner does not always have to be removed from the tension unit. The disk can remain on the tension devie and only the handgrip is displaced. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure presents a perspective view of the invention in accordance with a preferred version. 1 : Ring spanner 2 : Handgrip 3 : Engagement device 4 : Groove-shaped recess 5 : Tension unit 6,7 : Screw stems 8,9 : Engagement surfaces.
