Grafting fixing clamp structure

The utility model relates to the technical field of grafting, and discloses a grafting fixing clamp structure which comprises a plurality of sets of fixing plates, the fixing plates are arc-shaped, each fixing plate is provided with a rotatable and fixed rotating cam, the rotating cams are used for being in extrusion contact with branches, and an upper fixing structure and a lower fixing structure are jointly arranged among the multiple sets of fixing plates. The fixing structure comprises binding ropes, the binding ropes are arranged on the upper and lower side wall faces of the multiple sets of fixing plates, and the rotating cam is located between the two sets of binding ropes. After the fixing plates are attached to branches, the guide sliding blocks on the binding rope are clamped into the sliding grooves to slide, in this way, the upper sides of the multiple sets of fixing plates can be fixed through one binding rope, then the two free ends of the binding rope on the upper side are tensioned, and then k
