Cylinder body of hydraulic cylinder

The utility model relates to the technical field of hydraulic cylinders, and discloses a hydraulic cylinder body which comprises a cylinder body, a first round plate is fixedly installed at the bottom of the cylinder body, a hydraulic groove is formed in the bottom of the cylinder body, a buffer frame is placed in the hydraulic groove, a plurality of limiting blocks are arranged on the side face of the buffer frame, round holes are formed in the limiting blocks, and the first round plate and the hydraulic groove are fixedly connected through the round holes. A liquid inlet is formed in the side face of the cylinder body, and the round hole is communicated with the liquid inlet. The buffer frame is installed in the hydraulic groove, the buffer frame can protect the cylinder body, when the pressure is too large, the buffer frame can be damaged, a gap between the buffer frame and the cylinder body is released, a space for absorbing the pressure is formed, then the cylinder body is protected, a new buffer frame c
