Example 1:

Referring to fig. 1, the present embodiment provides an electric fixture for holding a denture blank 800, which includes: the movable chuck 200 is movably arranged along a first direction, and the driving mechanism 300 is in driving connection with the movable chuck 200 and is used for driving the movable chuck 200 to move along the first direction so as to enable the movable chuck 200 and the fixed chuck 100 to mutually cooperate to form a clamping space.

In the present embodiment, the movable chuck 200 is movably disposed in a first direction, which may be understood as a direction away from or near one side of the fixed chuck 100, and the movable chuck 200 may be moved toward or away from one side of the fixed chuck 100 by being driven by the driving mechanism 300. For example, the driving mechanism 300 may drive the movable chuck 200 to move near the fixed chuck 100, so that the movable chuck 200 and the fixed chuck 100 cooperate with each other to form a clamping space for clamping the denture blank 800; when the denture blank 800 needs to be disassembled, the driving mechanism 300 can be controlled to be powered off, so that the driving mechanism 300 does not provide clamping force for the movable chuck 200 any more, the denture blank 800 can be disassembled, or the movable chuck 200 can be driven to move away from one side of the fixed chuck 100, so that the movable chuck 200 and the fixed chuck 100 are opened, the denture blank 800 can be taken out, and the driving mechanism 300 can automatically control the movable chuck 200 to clamp or open.
