The invention discloses a multifunctional wood engraving machine. The machine comprises a multifunctional wood engraving machine comprises an operating table, support legs and a support frame, whereinthe operating table and the support legs are welded, sliding chutes are formed in the top of the support frame and one side of the operating table and fixedly connected with the support frame and theoperating table respectively, sliders are symmetrically arranged on one side of the operating table and embedded into the sliding chutes, the sliders and the support frame are welded, and a pneumaticslider is arranged at the top of the support frame and embedded in the sliding chute. The multifunctional wood engraving machine can well fix wood blocks, the loose state cannot be caused during engraving, accordingly, material waste caused by engraving can be avoided, an engraving cutter can be obliquely rotated, engraving at multiple angles is completed, the tedious steps of manual engraving are reduced, meanwhile, the working speed of engraving is accelerated, and the multifunctional wood engraving machine has broad application prospects in the future.
