1 . Stand for mounting rod-shaped parts, in particular Christmas trees, having the following features:
 having a foot part,   having a plurality of holding members which are positioned offset around a central axis and/or axis of symmetry of a receiving chamber and are each pivotable between a fixing position and a release position about a horizontal pivot axis or about a pivot axis having a horizontal component, characterised by the following further features:   a plurality of push bolts is provided in the circumferential direction of the stand,   the push bolts comprise mutually spaced raised portions between which grooves are formed,   the push bolts each pass through a through-opening in an insertion support means,   the push bolts are biased towards the holding members by a spring energy store,   a fixing and/or locking ring is provided, in which passage openings are formed which are offset in the circumferential direction and at least in part are aligned with the through-openings in the insertion support means and passed through by push bolts, and   the fixing and/or locking ring can be twisted between a release direction and a locking direction, the respective push bolts being displaceable towards or away from a tree trunk to be fixed through the aligned through-openings and the passage openings when the fixing and locking ring is twisted into the release position, whilst in the locking position of the fixing and locking ring, the push bolts are jammed in such a way that they cannot be displaced.   
     
     
         2 . Stand according to  claim 1 , characterised in that the passage holes are slot-like and comprise in the fixing and/or locking ring a tapering portion which in the locked position interacts with the raised portions and the grooves in the push bolts and locks them against axial displacement, and in that the slot-like passage openings comprise an extended portion in which the push bolts come to lie in the release position of the fixing and/or locking ring so as to make axial displacement of the push bolts possible in this position. 
     
     
         3 . Stand according to  claim 2 , characterised in that the slot-like passage openings comprise a rim which defines the passage opening and engages in a groove between two adjacent protrusions in the locking position of the fixing and locking ring. 
     
     
         4 . Stand according to  claim 3 , characterised in that the raised portions and the grooves located between two raised portions are arranged offset from the longitudinal direction of a push bolt and are positioned oblique thereto in such a way that when the fixing and locking ring is adjusted, the relevant push bolt can be moved towards the central axis and/or axis of symmetry with an additional axial force component. 
     
     
         5 . Stand according to  claim 1 , characterised in that the insertion support means comprises through-openings, which allow tilting of the push bolts passing through them, and in that when the fixing and locking ring is adjusted into the locking position, the push bolts can be tilted in such a way that the edges defining the passage openings engage between two raised portions in a groove, located between them, of the relevant push bolt and lock the push bolts against axial displacement. 
     
     
         6 . Stand according to  claim 5 , characterised in that, when the fixing and/or locking ring is adjusted into the locking position, the push bolts are tilted in such a way that the front end thereof, facing the central axis and/or axis of symmetry, is pivoted downwards, resulting in the holding members which cooperate therewith experiencing an additional force component and adjustment component towards the central axis and/or axis of symmetry. 
     
     
         7 . Stand according to  claim 1 , characterised in that the spring energy store impinges on the push bolts on the outwards-facing ends thereof. 
     
     
         8 . Stand according to  claim 1 , characterised in that the push bolts are formed by threaded bolts. 
     
     
         9 . Stand according to  claim 1 , characterised in that the raised portions or protrusions are formed as webs or ribs or as circumferential rings, the orientation of these raised portions or protrusions and the grooves formed between them being arranged at an angle other than 90° to the longitudinal axes of the push bolts, at least in some cases, in particular arranged at another angle which is less than 60°, less than 45°, less than 30°, less than 20° or less than 10°. 
     
     
         10 . Stand according to  claim 1 , characterised in that the raised portions or protrusions are formed only on two opposing faces of the push bolts. 
     
     
         11 . Stand according to  claim 1 , characterised in that the holding members have a cross-section which corresponds to a U profile. 
     
     
         12 . Stand according to  claim 1 , characterised in that the holding members are bent at the upper ends thereof counter to the contact surfaces thereof, at a variable angle. 
     
     
         13 . Stand according to  claim 1 , characterised in that the push bolts comprise on the outwards-facing ends thereof a guide means on which the spring energy store preferably engages. 
     
     
         14 . Stand according to  claim 1 , characterised in that the insertion support means consists of or comprises an insertion container which has at least one passage opening to the foot part comprising a stand shell. 
     
     
         15 . Stand according to  claim 14 , characterised in that the stand shell has a crimped circumferential rim. 
     
     
         16 . Stand according to  claim 15 , characterised in that transverse webs are arranged inside the crimped rim. 
     
     
         17 . Stand according to  claim 14 , characterised in that the stand shell is impinged on by detachable stand feet. 
     
     
         18 . Stand according to  claim 14 , characterised in that a slot-shaped indent formed on the stand foot comprises the crimped rim of the stand shell. 
     
     
         19 . Stand according to  claim 1 , characterised in that the foot part preferably comprises stand feet in the form of a stand shell, which accommodate weighting material in a concealed manner. 
     
     
         20 . Stand according to  claim 1 , characterised in that the foot part comprises stand feet having a recess for accommodating an energy store. 
     
     
         21 . Stand according to  claim 1 , characterised in that the foot part comprises feet, preferably in the form of a stand shell, which can be pivoted between an inwardly pivoted storage position and an outwardly pivoted operating position and which are preferably positively secured both in the inwardly pivoted and in the outwardly pivoted position thereof.
