Abstract

The utility model relates to a hand pressing lifting frame device for an agricultural tricar. A multiposition body lever structure is formed by a hand pressing lever, a clutch, a front and a back triangle supporting frames and a herringbone movable puller, and movable shafts are arranged on the front and the back supporting frames. So, by adjusting the position of the hand pressing lever on a fixed tooth knife only with very a little force, the height of a plough, namely the depth of ploughing a field can be controlled to realize the purpose of ploughing the field quickly. Because the leftwards and rightwards moving range of the movable puller is limited within the length range of the movable shaft, the utility model can ensure that adjacent crop seedlings can not be pressed when the field is ploughed and is harrowed when a dead furrow is pulled. The utility model has the advantages of simple structure and strong practicability and is suitable for agricultural cultivation in an agricultural underdeveloped area.
