Abstract

In a system for adjusting the position of a first member relative to a second, support member regarded as fixed, the support member comprises a base having an upright at each of its two ends. The first member is inside the two uprights of the support member and the uprights are substantially parallel to the axis of the first member. The position adjustment system is locked in a chosen position by a clamping device, whose component parts are mounted on a clamping rod passing through the two uprights and whose axis is the clamping axis, which is substantially perpendicular to the axis of the first member. The clamping device includes a cam-type immobilizing system outside one of the uprights, relative to the axis of the first member, between an outside face of that upright and a bearing member joined and substantially perpendicular to the clamping rod; a bearing member joined and substantially perpendicular to the clamping rod; a circular fixed cam prevented from rotating with respect to the upright of the support member and a circular mobile cam free to rotate on the clamping rod. The cam-type immobilizing system is locked or unlocked by an electrical remote control system.
