[0044] Working principle: When the first screw 12 needs to be removed, firstly, a rotational force is applied to the second screw 37 to remove the second screw 37 from the inside of the fixing column 35 and the support plate 36, and an upward flipping force is applied to the fixing column 35 to drive the rotating column 34 to rotate inside the connecting column 32. When the fixing column 35 and the connecting column 32 are on the same horizontal line, a pulling force is applied to the connecting column 32 to remove the connecting column 32 from the inside of the silicone block 31 and the fixing block 33, and then the silicone block 31 is removed from the inside of the connecting rod body 11, and the lubricating oil is poured into the outside of the first screw 12;
