[0031] Among them, in this embodiment, the above-mentioned support frame 1 includes two transverse rods 11 and two longitudinal rods 12, and the two transverse rods 11 and the two longitudinal rods 12 are all located in the same horizontal plane. In this embodiment, the transverse rods 11 and the longitudinal rods 12 are both in the shape of quadrangular prisms. The two transverse rods 11 are arranged at intervals, and the two longitudinal rods 12 are respectively fixedly connected to the two ends of the transverse rod 11, thereby forming an "I"-shaped support frame 1 with high structural strength. A handle 13 is fixedly connected to the top side of the longitudinal rod 12, and an anti-slip groove is provided on the outer surface of the handle 13 to facilitate workers to carry the sleeve mold of the utility model and align the welding limiter 3 on the sleeve mold with the position to be repaired of the white body.
