In order to be fixed seed crystal, also be socketed with the collar on the described draw-in groove.
As a kind of preferred, described shape of the mouth as one speaks bar is shape of the mouth as one speaks tungsten bar.
More preferably, the quantity in described shape of the mouth as one speaks hole is 1～3.
Compared with prior art, the utlity model has following beneficial effect:
1, draw-in groove of the present utility model is set to taper structure, just can be by the structure of seed crystal being arranged to be complementary with this draw-in groove, thus make seed crystal effectively be fixed on the utility model; Draw-in groove is arranged to the structure that increases gradually along the direction of the seedholder body the other end, the problem that just can effectively avoid seed crystal to glide, thus make seed crystal with of the present utility model fixing more firm, yield rate and the quality of raising product;
2, the utility model is provided with fluting, twines this fluting by tungsten filament, seed crystal can be fixed in the draw-in groove of the present utility model firmly, plays and strengthens fixing effect;
3, the utility model is by the cooperation in shape of the mouth as one speaks bar and shape of the mouth as one speaks hole, prevents that effectively seed crystal from deviating from draw-in groove, the more effective downslide that prevents seed crystal, thus make seed crystal and combination of the present utility model more stable, firm;
4, the setting of the utility model collar can be avoided shape of the mouth as one speaks bar to skid off from shape of the mouth as one speaks hole, thereby better seed crystal is fixed on the utility model;
5, operation of the present utility model is very easy, and by taper structure of the present utility model, can guarantee enough powerful weight capacities of the utility model, thereby make finished product rate and quality all obtain guarantee;
6, because the set-up mode in the utility model has ensured the thermal conduction effect of seed crystal, give the enough growth powers of crystal; Thereby be conducive to the growing large-size crystal, reduce production costs;
7, the utility model is simple in structure, cheap and convenient, practical.

Embodiment
Below in conjunction with embodiment and accompanying drawing thereof, the utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Embodiment 1
As shown in Figure 1 and Figure 2, the utility model mainly is comprised of the seedholder body 2 that an end has a draw-in groove 1, the taper structure that described draw-in groove 1 increases gradually for the direction along seedholder body 2 the other ends.By above setting, seed crystal is arranged to the structure that is complementary with taper structure, seed crystal is positioned in this draw-in groove 1, just seed crystal and the utility model can well be fixed by above-mentioned setting.
By the operation of reality, draw when the difference of the large end of described taper structure and small end is 2～5mm, just can guarantee enough powerful weight capacities of the utility model, thereby finished product rate and quality all are protected.
In order better seed crystal 7 to be fixed in this draw-in groove 1, an end that has draw-in groove 1 at described seedholder body 2 is provided with fluting 4.
The set-up mode of fluting 4 has multiple, and as the selection of optimum, the quantity of this fluting 4 is 1～3.The opening that the utility model can all arrange two correspondences in upper surface and the lower surface of draw-in groove 1 forms a fluting 4, four openings are set in the present embodiment altogether, the opening of upper surface and lower surface is corresponding one by one, and namely the quantity of fluting 4 is set to two in the present embodiment; The length of this fluting 4 is 2～5mm, and the degree of depth is 2～5mm.
The utility model can also form fluting 4 by ring groove is set, and forms ring groove thereby a circle groove namely is set along seedholder body 2 sides in the position of draw-in groove 1, and this ring groove is fluting 4.Ring groove is set to 2 in the present embodiment, is respectively adjacent to the large end of taper structure and the position of small end.Twine this fluting 4 by tungsten filament and seed crystal 7 can be carried out colligation and fix, reach stable, purpose firmly.
