The invention discloses a device for assisting in manual operation of fruits, and belongs to the technical field of fruit picking. When the fruits are picked, the device for assisting in manual operation of the fruits is moved to the portion under a fruit tree through a moving assembly, the position, relative to a fixed rod, of a telescopic rod is adjusted to change the overall length of a rotating rod, and a round frame and a round frame cover on the telescopic rod are close to the fruits needing to be picked. Through a control assembly, the round frame and the round frame cover are opened, then the angle of the rotating rod is adjusted through a rotating assembly, the fruits to be picked are located between the round frame and the round frame cover, pedicels of the fruits to be picked are located between an upper blade and a lower blade, then the round frame and the round frame cover are closed through the control assembly, the upper blade and the lower blade are closed, the pedicelsof the fruits to be picked are cut off, and finally the fruits enter a collecting assembly. By the adoption of the device, the aim of rapidly and efficiently picking the fruits can be realized without damage to the fruits, meanwhile, the burden of orchard workers is reduced, and the efficiency of picking the fruits can be improved.
