The protective plate 2 arranged on the palm part adopts a small piece unit structure, so that the hand can be manually moved without being affected when various movements are performed. In the present utility model, the protective plate 2 is a metal protective plate 2, for example, a stainless steel protective plate 2, and a sharp protrusion for increasing friction is arranged on the protective plate 2, and the height of the sharp protrusion is 2-4 mm. The first unit provided by the present utility model is mainly convenient, stable and safe for holding the sorghum stem.

[0044] The protective plate 2 arranged on the protective glove 1 in the present utility model can be fixed by sewing or other ways, for example, adhesive fixing.

[0045] The second unit is used to hold by the other hand, and the threshing operation can be performed after the second unit is held by the other hand. The structure of the second unit is designed as a circular table type structure in the utility model, and the second unit is a whole metal shell, and the outline thereof is a circular table type structure or a shuttle type structure placed horizontally. The second unit includes two unit bodies 3 which are the same in structure and are hinged (hinged together by a metal hinge, and in use, one side of the hinge faces the inner side of the palm, and the other side can be opened and closed through the opening and closing action of the palm). One of the unit bodies 3 is provided with a single-finger sleeve for the thumb to pass through, and in order to improve the stability of the unit body 3 held on the palm, a binding belt can also be arranged on the unit body 3, and the two unit bodies 3 are fixed on the palm and fingers (here, the fingers include the index finger, the middle finger, the ring finger and the little finger, and do not include the thumb) through the binding belt before use. The other unit body 3 is provided with a multi-finger sleeve for other fingers to pass through, so that the opening and closing action of the thumb and the palm and the other four fingers can realize the opening and closing of the two unit bodies 3. The second unit has a threshing cavity for the sorghum rod to pass through, and a threshing plate 4 is fixedly arranged on the inner side of the unit body 3. The threshing plate 4 is a fan-shaped structure, and the threshing plate 4 is arranged in the second unit and perpendicular to the axis of the second unit. The second unit is composed of two unit bodies 3, and the threshing plate 4 is arranged on each of the two unit bodies 3, and the threshing plates 4 arranged on the two unit bodies 3 are arranged in pairs. After the unit bodies 3 are buckled together, the two threshing plates 4 arranged in pairs can be assembled into a circular ring structure, and the center hole diameter of the circular ring structure is 0.5-1.0 cm. One side of the threshing plate 4 is connected with the inner side of the unit body 3 (the connection structure can be a fixed connection structure or an elastic connection structure), and the other side of the threshing plate 4 is an arc-shaped edge (i.e. a structure forming a center hole), and an edge tooth (sawtooth structure) for threshing is arranged on the arc-shaped edge. After the two unit bodies 3 are buckled, the threshing plates 4 arranged on the two unit bodies 3 cooperate to form a ring structure for the sorghum rod to pass through.
