Power output shaft is between first gear and second gear, and is more steady when transmission is meshed, and power loss is smaller.Axle is put into and goes up most or bottom if output power, and is more loaded down with trivial details with the such relative structure of two-stage transmission of second gear drive again by first gear, is unfavorable for the debugging of complete machine.

Improve, described second rotating shaft is connected by irregularly-shaped hole with inner splint again, and inner splint is located with irregular hole with outer blade, with external splint and screw outer blade is being fixed on the axle head of second rotating shaft in second rotating shaft again.Irregularly-shaped hole can be a square hole or tri-angle-holed or the like.

What be highly profitable is that described inner blade is connected with adapter sleeve with location, irregular hole with screw.

Preferably, the two ends of described first rotating shaft are provided with in the cutting head inner chamber by bearing.

At last, described mutually despun inner blade and outer blade can be the concentric rotary setting.

Compared with prior art, the invention has the advantages that: owing to leave certain interval between inner blade and the outer blade, and one of them blade face relative with another blade is provided with a circle convex tendon or local convex tendon section constitutes the convex tendon circle in described inner blade and the described outer blade, such two blades are when rotating, because accumulated error and the blade made have certain beat, two blade collisions mutually, because at least one blade is provided with a circle convex tendon in two blades, such two blades before collision because the cutter tip direct collision of keeping out thereby can avoid two blades of convex tendon is arranged, both prolonged the service life of blade, solve the beat of making accumulated error and blade again, also guaranteed the clearance distance between two blades, particularly inner blade is to adjust spacing adaptively, the spacing of two blades can be controlled in the scope of design, avoid the excessive or too small common fault of spacing, reasonable in design, production and assembly are easy.
