Abstract

The invention relates to a method and an apparatus for clamping the trunk of a Christmas tree or the like, consisting of a stand, with at least three clamping jaws (5), which are disposed in a base plate (1) with an opening (2) for accommodating the trunk, are distributed about this opening (2) and can be moved into the accommodating opening (2) for clamping the trunk. In order to be able to adapt the clamping jaws easily to the cross section of the trunk, to clamp the trunk securely with a small lift and to undo or eliminate the clamping easily, a fastener, which can be moved in two opposite directions and, in one direction moves the clamping jaws (5) out of the accommodating opening (2) and, in the other direction, initially releases the clamping jaws (5) so that they can move to lie against the trunk and subsequently presses the clamping jaws (5) with the required clamping force against the trunk, is assigned to the base plate (1).
