The device is particularly suitable for fixing small and medium-caliber ceramic cultural relics.

[0034] When the device is used, the cultural relic is placed on the turntable 2 so that the cultural relic and the turntable 2 are coaxially arranged, and then the height of the lifting sleeve 4 is adjusted, the lower end of the center rod 7 is extended into the cultural relic, the pressing assembly 9 is abutted against the bottom wall in the cultural relic, and then the center rod 7 and the rotating sleeve 6 are relatively fixed by the first locking assembly 8, thereby fixing the bottom of the cultural relic. The height of the clamping sleeve 10 is adjusted so that multiple clamping plates 11 are extended into the entrance of the cultural relic, and the conical structure formed by multiple clamping plates 11 is used to clamp the entrance of the cultural relic, and then the clamping sleeve 10 and the center rod 7 are relatively fixed by the second locking assembly 12, thereby fixing the entrance of the cultural relic. The device fixes the cultural relic in two ways, so the fixing effect is good, and the problem of cultural relic shaking will not occur. In the process of cultural relic restoration, the device is fixed by the inside of the cultural relic, so that the staff can repair the surface of the cultural relic. Since the turntable 2 and the rotating sleeve 6 are both rotatably installed, the cultural relic can be rotated. Rotating the cultural relic during restoration can facilitate the staff to operate, thereby improving the restoration efficiency.

[0035] In this embodiment, the turntable 2 is installed on the fixed base 1 through a planar thrust bearing 22. A locking bolt 23 is provided on the outer side of the turntable 2.
