[0001] The present application relates to the field of diamond press matching tool, especially to an inner support balance lifting appliance for steel ring of diamond press. BACKGROUND

[0002] The cubic press is a key equipment for synthesizing superhard materials, which generates high pressure up to several GPa through six working oil cylinders, and cooperates with high temperature conditions to synthesize materials such as artificial diamond. The top hammer of the cubic press is one of the core components of the cubic press, which directly participates in the formation of the synthesis cavity and the maintenance of the high pressure environment, and is an important factor to determine the quality of diamond synthesis. The steel ring accessory of the top hammer is an irregular whole, but its fixing screw is evenly distributed around a regular circle. When replacing the hammer head of the top hammer, the steel ring needs to be hoisted as a whole. The current hoisting method is to use a simple lifting hook to pass through one of the screw holes to directly lift. This method is unstable in the center of gravity and easy to slip off, and on the other hand, it also needs manual adjustment of the landing posture when hoisted to the designated position, which is extremely inconvenient to operate and has high safety risk.
