Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] The best time to pick chestnuts is usually from September to October each year. When the fruit shell changes from green to yellow-brown and begins to crack naturally, it indicates that the chestnuts are ripe and can be picked. Picking chestnuts is a job that requires a lot of labor and high-efficiency operation. Because the shell of chestnuts has thorns, if the operation is improper, it will not only reduce the efficiency of picking, but also cause hand skin damage and swelling and pain. In the prior art, chestnuts are generally picked with tools such as scissors or pliers;

[0021] Scissors and pliers are a kind of common hand tools, usually composed of two metal sheets connected by an axis, which can be opened and closed to cut objects and pick up items. The existing scissors and pliers for picking chestnuts can only be suitable for single picking and picking operations, resulting in that in the process of picking chestnuts, the work of cutting chestnut branches, removing seeds from chestnut shells and breaking chestnut seed shells need to rely on three different tools to perform the operations respectively. Switching back and forth between different tools not only reduces the efficiency of picking fruits, but also greatly increases labor costs. Not only does it fail to bring good economic benefits, but the single function is simply unable to adapt to and meet the needs of production and life, and is not worthy of wide promotion and application.

During the closing process of the first shear blade 1 and the second shear blade 2, the twig cutting mechanism is used to cut the twig, and the chestnut hanging can be removed. The twigs are taken from the chestnut tree, and the chestnut branch cutting work is completed. The chestnuts taken from the tree are all in a cracked state, and the chestnuts on the surface are ripe and can be picked. After the twigs with chestnuts hanging on them are taken down, the chestnut seed fruits are dug out from the cracked chestnut shells by using the shell opening and fruit picking mechanisms at the top ends of the first shearing blade 1 and the second shearing blade 2, and the chestnut shell seed removal work is completed. Finally, the chestnut seed fruit shells are cut open by using the saw shell breaking mechanisms on the first shearing handles 5 and the second shearing handles 6, and the chestnut seed shell breaking work is completed. Finally, the flesh in the seed shell is taken out, and the entire chestnut fruit picking work is completed.
