The cylinder assembly includes a pressure plate 3, a cylinder and a cylinder pressure rod 4, and the pressure plate 3, cylinder pressure rod 4 and cylinder are connected in sequence. The pressure plate 3 is used to press the oil rail bracket 5 in a pre-positioned state downward to the target position. The pressure plate 3 is provided with two through holes, and the two through holes are used to pass through the guide column 2. One end of the cylinder pressure rod 4 is provided at the center of the pressure plate 3, and the other end is connected to the output end of the cylinder. The cylinder pressure rod 4 is used to push the pressure plate 3; the other end of the cylinder is connected to the booster pump, and the booster pump is used to perform a second press-fit on the oil rail bracket 5.
