The invention provides a pear tree two-arm direct-motion type shed frame tree shape which comprises a tree trunk. The tree trunk has two boughs which grow in a direct-motion mode, and base angles of the two boughs are 45 degrees. When reaching a frame-climbing point, the boughs are fixed on a horizontal shed frame in a direct-motion mode, and extended long branches of the boughs are guided onto an elevation guide line in a perpendicular mode. The boughs have long placed fruit branches which are arranged in parallel and vertically extend into intervals. Before the two boughs climb a frame, two horizontal robust side position branches which are pulled along the reverse direction to be parallel to the boughs after the horizontal robust side position branches grow upward to the frame face. The side position branches have F-shaped single-shaft long placed type fruit branches which are arranged in parallel and vertically extend to the intervals. The tree shape only has the two boughs, and therefore the problems that an inclined crown appears easily in a three-bough tree shape and the main boughs intersect are solved. The two boughs oppositely extend in a direct-motion mode and do not influence each other. The two-bough tree shape is easy to reshape, and the two boughs are easy to form after the trunk is fixed. The phenomenon of lack of branches appears in a three-bough shed frame due to the fact that sprout force of a pear tree is weak. The three shape has the advantages that cultivation density is high, early-stage output is high, light conditions are good, the branches are easy to arrange in an ordered mode, uniformity of fruit quality is high, and standardization is easy to achieve.
