In the case of a stand having three stand legs which can pivot and are articulated on a stand head, the height of a centre column, which can be displaced in said stand, is adjustable by means of a clamping ring. In this case, the clamping ring engages by means of a concentric recess with a concentric projection on the top of the stand head. It furthermore has an eccentric hole with a small diameter, through which at least one clamping part, which runs parallel to the centre column, can be pressed against said centre column. |
