The fixing plate 3 is a three-equal-sided plate, two of which have two lifting screw holes 6 on two sides, and one lifting screw hole 6 is opened on the other side, and the lifting screw holes 6 are connected to the double-hole clamp plate 5, the single-hole clamp plate 51 and the lifting device;

[0020] See also Figure 2 , Figure 3 , Figure 4 Different numbers of grooves are correspondingly provided on the double-hole clamp plate 5 and the single-hole clamp plate 51, and the grooves are convenient for disassembly and assembly. The lower ends of the double-hole clamp plate 5 and the single-hole clamp plate 51 are clamped with the end of the cylinder head 1, and the distance between the upper and lower ends can just fit tightly against the upper end surface of the cover plate and the cylinder liner 1, so that the tool and the cylinder liner 1 are clamped and fixed. Through holes are provided in the middle of the fixing plate 3, the circular plate 2 and the protrusion 201, and a connecting bolt 4 is provided in the middle of the fixing plate 3. The connecting bolt 4 is connected to the fixing plate 3, the circular plate 2 and the protrusion 201 in sequence through the through hole.
