[0021] The present utility model will be further described below with reference to the accompanying drawings through examples.

[0022] A fixed clamp structure for a header linkage rod, comprising a linkage rod oil cylinder seat 1, a linkage rod 3, and a linkage rod fixed clamp 7. An oil cylinder 2 is arranged on the linkage rod oil cylinder seat 1, and the linkage rod oil cylinder seat 1 moves in the same direction as the oil cylinder 2. The linkage rod oil cylinder seat 1 is connected to the linkage rod 3 through the linkage rod fixed clamp 7. The linkage rod fixed clamp 7 includes a first fixed clamp plate 71, a U-shaped groove 72, and a second fixed clamp plate 73. The first fixed clamp plate 71 and the second fixed clamp plate 73 are connected through the U-shaped groove 72 to form a V-shaped structure. A fastening screw 6 is arranged inside the V-shaped structure, and the V-shaped structure is connected to the linkage rod oil cylinder seat 1 through the fastening screw 6 and a fastening nut 4. Fixing holes 74 and 75 are respectively arranged on the first fixed clamp plate 71 and the second fixed clamp plate 73, and the fixing hole 74 and the fixing hole 75 are communicated through a linkage rod fixed clamp notch 8. The linkage rod 3 is arranged inside the fixing hole 74 and the fixing hole 75.
