In the oil tea fruit picking process, the oil tea fruit on the branches is knocked down mainly by carding and high-speed rotation of the vibration exciting rods 81 of the vibration exciting teeth 8, so that acting forces such as pulling, wrestling and the like do not exist on fruit handles, and the branch deformation is small; the diameter of the branch is far smaller than the gap of each exciting rod 81, and the rubber sleeve 82 is in direct contact with the branch, so that striking damage to the bark and buds is small; the horizontal inclination angle of the excitation teeth 8 inserted into the tree body and the included angle between every two excitation rods 81 are adjustable, and can be adjusted according to field practice, so that the disturbance to the oil-tea tree body is further reduced.
