The poultry meat is an indispensable food in life of people, and particularly the wing meat and the leg meat in the poultry meat are delicious food on dining tables of people. The whole poultry is cut and sold, so that the economic value of meat can be improved, and convenience is provided for cooking meat. In the processing process of poultry meat, manual cutting needs a plurality of procedures, and pollution and bacterial breeding are easily caused. In the prior art, a plurality of automatic cutting technologies for poultry meat are designed, but all the technologies are not perfect.

KR102323739B1 discloses an automatic chicken cutting device having a rotary blade and a blade groove for cutting chicken. The blade continuously rotates along a pair of chains installed on the frame and is installed on a plurality of shifting chopping boards for shifting, and the first rotary blade part and the second rotary blade part respectively continuously cut the chicken along the transverse direction and the longitudinal direction. The whole chicken in the patent can automatically rotate and advance in the delivery process without human intervention, and respectively cut transversely and longitudinally; however, the wings and legs are not cut from the torso, and the transverse and longitudinal cuts need to be made at two stations, adding to the wind removal of contamination and bacterial growth, complicating the equipment, and not being efficient.

Chinese patent CN213136879U discloses a safe and fast chicken cutting device, which adjusts the cutting blade in the vertical and horizontal directions by driving a cylinder and a rotary cylinder, the rotary cylinder can cut chicken transversely and longitudinally, and the chicken is cut into a plurality of blocks rapidly and completely. However, the whole chicken is directly cut into small pieces by the cutting method, the chicken wings and the chicken legs cannot be separated, the separated chicken obtained by separating the chicken wings, the chicken legs and the chicken body has higher food value and economic value, and the value of the whole chicken is reduced by the cutting method.

Chinese patent CN210414651 discloses an automatic cutting device for poultry, which comprises a poultry fixing frame, a stop block, a boning knife, an air cylinder and a clamp ring. After the device fixes poultry by utilizing a clamping ring, firstly, starting a cutting device positioned at the legs of the poultry to cut off the two legs of the poultry; the second step is to start the cutting device at the wing part of the poultry to cut off the double wings of the poultry, the third step is to start the cutting device at the joint of the neck and the chest of the poultry to cut off the head and the neck of the poultry, the fourth step is to start the cutting device at the joint of the head and the neck of the poultry to cut open the head and the neck of the poultry, and finally, the clamping ring 3 is opened to place the body parts of the poultry after cutting in a classified manner. According to the scheme, when poultry meat is cut, although leg meat and wing meat are divided, the leg meat and the wing meat are respectively cut by using different cutting devices, so that the cutting efficiency is low, different cutting devices are required to be arranged, the equipment is complicated, and the manufacturing, maintenance and use costs of the equipment are increased.
