The shell and the cylinder are coaxial. The bottom valve is disposed at the bottom of the cylinder. The piston is disposed at the lower end of the piston shaft. The guide bearing sleeves the piston shaft. The lower portion of the guide bearing is in interference fit with the cylinder; the upper portion of the guide bearing is in interference fit with the shell. The oil seal base is disposed on the upper portion of the guide bearing and is in interference fit with the shell. A chamber is arranged between the cylinder and the shell. A relief valve having an oil inlet and an oil outlet is disposed on the oil seal base. The relief valve penetrates the oil seal base and the guide bearing. The oil inlet is communicated with the cylinder. A pipe whereby the oil outlet is communicated with the chamber is arranged on the guide bearing. An oil incoming one-way valve is arranged on the side wall of the other end, facing the oil seal base, of the cylinder. The cylinder is communicated with the chamber through the oil incoming one-way valve. The anti-oil-leakage shock absorber prevents oil leakage.
