When the rotating plate 24 rotates, the end of the connecting frame 35 close to the mounting seat 32 is moved upward through the second swing arm 31, and the end of the connecting frame 35 close to the saw blade 37 is moved downward. When the saw blade 37 contacts the bamboo, the bamboo can be cut, and the saw blade 37 is moved along the two ends of the bamboo. The position near the bamboo node is cut so that no bamboo node remains after the cutting, and only the bamboo tube part is left. After the cut bamboo is transported to the conveying frame 38 through the second feeding frame 6, the fifth motor 40 is started. The fifth motor 40 cooperates with the second reducer 41 to rotate the second rotating shaft 42. The rotation of the second rotating shaft 42 can rotate the sprocket 39 connected thereto. While the sprocket 39 rotates, another sprocket 39 is driven to rotate synchronously through the chain 43. When the cut bamboo falls on the chain 43, the chain 43 drives the bamboo to move toward the fixed plate 53. When the bamboo moves on the conveying frame 38 to the fixed plate 53, the bottom of the pressing plate 48 will be against the bamboo. This can effectively prevent the bamboo from shaking when the cutting knife 45 cuts the bamboo.When the bamboo is against the cutting knife 45 on the fixed plate 53, the baffle 51 on the chain 43 will squeeze the bamboo, and the cutting knife 45 can be used to cut the bamboo, which makes the device more efficient in cutting the bamboo.
