The invention discloses a single-shaft wood carving machine. The single-shaft wood carving machine comprises a fixed seat, a controller, a motor, a push plate, a brush, a fixing groove, first slidinggrooves, a worktable, a hydraulic cylinder, a fixing shell, limiting holes, a second sliding groove, a sliding block, a connecting rod, a fixing ring, a corrugated pipe, a drill bit, springs, a push block, a limiting block, a pressing block and an accommodating groove. The push plate of the carving machine facilitating chipping clearing moves through the hydraulic cylinder, and the brush at the bottom end of the push plate is clamped at the fixing groove so that chippings and accumulated water in the fixing groove can be cleared thoroughly, the cleanliness of the worktable is ensured, following carving work is well prepared, and the working efficiency is improved; and the corrugated pipe is fixed in the fixing ring, the fixing ring is fixed through the fixing shell and limited through thelimiting block, thus the stability of the corrugated pipe is strengthened, the cooling effect is better, meanwhile, the height is convenient to adjust, and the cooling requirements of the drill bits with different lengths are met.
