| Zusammenfassung: | The utility model relates to the technical field of supports, and particularly discloses a three-section double-rod supporting direct-seeding support which comprises a first supporting rod set, a second supporting rod set and a third supporting rod set, and the second supporting rod set is rotationally connected with the first supporting rod set and the third supporting rod set through connecting pieces. The connecting pieces are installed at the end of the first supporting rod and the end of the third supporting rod, the first supporting rod set, the second supporting rod set and the third supporting rod set are each composed of two parallel supporting rods, and the outer sides of the supporting rods are connected with the connecting pieces through springs. The double-supporting-rod design is adopted, the springs are arranged on the outer sides of the supporting rods to increase fixing force and pulling force, no matter how the third supporting rod set swings to the two sides, the two supporting rods can be |
