It can realize the automation and standardization of the grafting process, improve the grafting speed and survival rate, and reduce labor costs. Camellia oleifera grafting machine generally adopts cleft grafting for grafting. The grafting process is: manually feeding rootstock seedlings and scion seedlings, the machine automatically cuts and splits the rootstock, cuts the scion, docks the scion and the rootstock, and clamps. At present, when cutting the scion of camellia oleifera, the angle of the cutting blade for cutting the scion is fixed, which is not convenient for adjusting the cutting. For camellia oleifera scion with different diameters, in order to ensure the survival rate after grafting, the grafting port requirements of camellia oleifera scion with different diameters are also different. It is necessary to adjust the cutting angle of the grafting port, resulting in poor applicability of the existing scion cutting device. Therefore, it is necessary to design a scion cutting device for camellia oleifera grafting machine to improve the above problems. Utility Model Content

The camellia wood is clamped by the camellia wood clamping mechanism 10 and moved to the cutting blade 8. The pull-down cylinder 3 is retracted to move the cutting blade 8 up to the cutting position, so that the camellia wood is placed between the pair of cutting blades 8. Then the finger cylinder 5 drives a pair of clamping claws 6 to clamp, so that the pair of cutting blades 8 cut into the camellia wood, and then the pull-down cylinder 3 is extended to complete the V-shaped cutting of the camellia wood. Then the finger cylinder 5 drives a pair of clamping claws 6 to open, preparing for the next cutting. The camellia wood cutting device imitates the movements of people when cutting camellia wood. Compared with the traditional mechanical V-cutting forming method, the cutting is smoother, more conducive to grafting, convenient and efficient, and greatly improves the grafting efficiency.

[0021] In this embodiment, if Figure 2 and Figure 3 As shown, a clamping block 701 is fixedly connected to one side of the angle adjustment block 7, and a clamping groove 601 is provided on the side of the clamping jaw 6 close to the angle adjustment block 7.
