The invention discloses a cutting device for bamboo shoots. The cutting device comprises a machine seat, a supporting mechanism, a limiting mechanism and a tool with a cavity are arranged on the machine seat, the supporting mechanism comprises a supporting table and two rotary shafts, and the supporting table is fixedly connected with the machine seat, a groove is formed in the middle of the supporting table, the two rotary shafts are arranged in the groove, and a sealing plate is rotatably connected to each rotary shaft; first pressing springs are arranged between the sealing plates and the bottom of the groove, limiting tables are arranged at the other ends of the sealing plates, through holes are formed in the ends, away from the sealing plates, of the limiting tables, and the through holes communicate with steam engines; the limiting mechanism comprises two supporting frames, the two supporting frames are arranged on the two sides of the supporting table correspondingly, a rotary arm is hinged to each supporting frame, and second pressing springs are arranged between the rotary arms and the supporting frames; an iron wire is arranged between the tool and a rack; and a heating resistance is arranged in the tool, and a plurality of heat dissipation holes communicating with a cavity of the tool are formed in the tool. According to the technical scheme of the cutting device for the bamboo shoots, the problems that a traditional technological chain for bamboo shoot processing is long, and the bamboo shoots on the surface of the tool need to be washed are mainly solved.
