Stand for clamping mast-shaped or staff-shaped parts, especially Christmas trees, with a base plate, at least two holding elements contiguous with a receiving space for receiving the mast or staff-shaped part, a locking device (50, 60) and a flexible force transmission device, wherein the stand has the following features: - the holding elements are arranged, offset at an angle, around a central axis of the receiving space, and each around a horizontal swivelling axis, or a swivelling axis with horizontal components, and are able to swivel away from the central axis in the direction of a release position and towards the central axis in the direction of a fixing position; - the force transmission device leads from the locking device (50, 60) to the holding elements, which are movably coupled with the locking device (50, 60) by means of the force transmission device; - each holding element is placed between each of two diverting devices connected with the base plate, each of which devices guides and diverts the force transmission device in a first vertical distance from the base plate; - by guiding the locking device (50, 60) over from an unlocking position in the direction of a locking position, the force transmission device is drawn, and/or force-loaded, in a drawing direction, to the locking device (50, 60), so that the locking device (50, 60), by means of the force transmission device, acts against or prevents a swivelling of the holding elements in the direction of the release position, characterised by the following features: - the holding elements each include a locating lever with a guiding device, by means of which the force transmission device is guided and through which, on the locating lever, a force directed onto the base plate can be exerted by the force transmission device, and a supporting lever supported and rotationally bearing on the base plate; - each locating lever is connected to swivel freely with one holding element each around a first horizontal axis and each locating lever is additionally connected to swivel freely each with a supporting lever around a second horizontal axis offset in parallel to the first horizontal axis; - the supporting levers are each supported at least indirectly on the base plate; - an angle (α) enclosed by the locating lever and the supporting lever is selected such that by swivelling a holding element in the direction of its release position, the angle (α) between the locating lever and the supporting lever is altered such that the locating lever and the force transmission device guided in its guiding device are swivelled away from the base plate and a second vertical distance of the force transmission device and/or the guiding device from the base plate is greater than the first vertical distance. - the holding elements are arranged, offset at an angle, around a central axis of the receiving space, and each around a horizontal swivelling axis, or a swivelling axis with horizontal components, and are able to swivel away from the central axis in the direction of a release position and towards the central axis in the direction of a fixing position;
