Novel polypeptide solid-phase synthesis device accessory

The utility model discloses a novel polypeptide solid-phase synthesis device accessory, and relates to the technical field of polypeptide solid-phase synthesis devices, in particular to a novel polypeptide solid-phase synthesis device accessory which comprises supporting legs, a mounting plate is fixedly mounted at the tops of the supporting legs, and a fixing hole is formed in the middle of the mounting plate. A fixing ring is arranged between the two mounting plates, a glass bottle is arranged in an inner cavity of the fixing ring, and limiting sleeves are fixedly mounted on the left side and the right side of the fixing ring. According to the novel polypeptide solid-phase synthesis device accessory, the flow of a liquid raw material can be controlled by rotating a flow limiting ball valve and utilizing the overlapping area between a through groove formed in the middle of a baffle and a first flow guide pipe, and a driving gear can rotate by rotating a torsion rod, so that a linkage gear is driven to rotate
