[0023] By adopting the above solution, by providing the adjustment mechanism 6, it is possible to make it easy for users to operate when adjusting the angle of the cutter head 3, and it is convenient to use.

[0024] refer to Figure 3 The positioning mechanism 7 includes a connecting rod 701, a trapezoidal block 702, a positioning rod 703 and a compression spring 704. The rear side of the movable column 604 is fixedly connected to the front side of the connecting rod 701, the surface of the connecting rod 701 contacts the surface of the trapezoidal block 702, the top of the trapezoidal block 702 is fixedly connected to the top of the positioning rod 703, the right side of the positioning rod 703 is fixedly connected to the left side of the compression spring 704, the right side of the compression spring 704 is fixedly connected to the inner wall of the positioning cavity 5, and the left side of the positioning rod 703 passes through the interior of the cutter head 3.

[0025] By adopting the above solution, by providing the positioning mechanism 7, the angle can be stably fixed after being adjusted to prevent shaking during use.

[0026] refer to Figure 3 and Figure 4 The surface of the cutter head 3 is provided with two fixing grooves 8 , which are used in conjunction with the positioning rod 703 .

[0027] By adopting the above solution, by providing the fixing groove 8, the positioning rod 703 can be in close contact during insertion to prevent loosening during use.

[0034] The working principle of this utility model:

[0035] When in use, the moving rod 601 is pulled upward, and the moving rod 601 drives the fixed column 602 to move upward, and the surface of the fixed column 602 squeezes the inner wall of the travel hole to make the fixed column 602 move upward, and the surface of the fixed column 602 squeezes the inner wall of the limit groove 11 to make the cross bar 603 rotate counterclockwise around the rotating shaft as the center. During rotation, the inner wall of the travel hole squeezes the surface of the moving column 604 to make the moving column 604 move downward, and the moving column 604 drives the connecting rod 701 to move downward. The surface of the trapezoidal block 702 is squeezed by the surface of the connecting rod 701 to move the trapezoidal block 702 to the right, and the trapezoidal block 702 drives the positioning rod 703 to move to the right. The positioning rod 703 moves to the right along the moving trajectory provided by the limiting block 9 and compresses the compression spring 704 at the same time, so that the positioning rod 703 moves to the inside of the positioning cavity 5. At this time, the angle of the cutter head 3 can be adjusted. After completion, the moving rod 601 is released, and the positioning rod 703 is reinserted into the inside of the fixing groove 8 through the rebound force of the compression spring 704.

[0036] To sum up: the sickle with an auxiliary structure for wheat harvesting solves the problem that the angles of the blade and the wooden handle are fixed when the sickle is in use, which is easy to be cut when taking it, by arranging a grip 1, a fixing sleeve 2, a cutter head 3, a positioning block 4, a positioning cavity 5, an adjusting mechanism 6, a moving rod 601, a fixing column 602, a cross bar 603, a moving column 604, a positioning mechanism 7, a connecting rod 701, a trapezoidal block 702, a positioning rod 703, a compression spring 704, a fixing groove 8, a limiting block 9, a travel rod 10 and a limiting groove 11. In order to facilitate the taking of the sickle, a sickle with an auxiliary structure for wheat harvesting is proposed, wherein the angle of the cutter head of the sickle can be adjusted when the sickle is not in use, so as to facilitate its transportation and taking.
