The invention discloses a fixing device for wood carving. The fixing device mainly comprises a shell, wherein a clamping mechanism for fixing carving raw materials is arranged in the shell, a drivingcavity is arranged in the shell, a rotating mechanism capable of rotating the clamping mechanism is arranged in the driving cavity, a driving mechanism capable of providing power for the device and controlling the device is arranged on the left side of the rotating mechanism, and a lifting mechanism capable of lifting the clamping mechanism is arranged on the left side of the rotating mechanism. When wood needs to be fixed, the wood is placed in the clamping mechanism to be clamped manually, if the wood needs to be lifted, the lifting mechanism is started to lift the fixed wood, if the wood needs to be rotated, the rotating mechanism is started to rotate the fixed wood, the wood does not need to be fixed manually by a person, the fixing stability and the safety are improved, and the lifting and horizontal rotating operations can be carried out when the wood is fixed, and engraving is more convenient.
