Multi-shaft fixing seat of high-precision numerical control lathe

The utility model relates to the technical field of multi-shaft fixing seats, in particular to a high-precision numerical control lathe with a multi-shaft fixing seat which comprises a mounting ring, two sliding grooves are formed in the inner wall of the mounting ring, sliding rings are connected in the two sliding grooves in a sliding mode, and clamping arms are fixedly connected to the inner walls of the two sliding rings. The output end of an electric telescopic rod drives a connecting block to move, the connecting block moves to drive a rotating ring and an arc-shaped rack to rotate, the arc-shaped rack drives a rotating gear and a threaded rod to rotate, and the threaded rod rotates to drive two U-shaped sliding rods and a pressing block to be away from each other, so that the pressing block is away from a tooth block; the rotating gear rotates to drive the sliding ring to rotate, the sliding ring rotates to drive the clamping arm to rotate, and after adjustment is completed, the output end of the elect
