[0008] Furthermore, a mounting block is provided at the lower end of the telescopic cylinder, and the mounting block is provided with a guide groove corresponding to the manual pull rod.
[0009] The utility model has the following advantages: based on the structure of the automatic oil drain valve composed of the telescopic cylinder, the automatic pull rod and the oil-sealing ball valve, the overall structure is changed and improved, and a manual pull rod is introduced. When the cylinder cannot work and the automatic oil drain function fails, the oil-sealing ball valve can be lifted up by the automatic pull rod to perform the oil drain operation, thereby ensuring that the oil drain can be carried out normally. By utilizing the ingenious structure of providing a ball valve through hole on the oil-sealing ball valve, the lower end of the automatic pull rod passes through the ball valve through hole of the oil-sealing ball valve, and a stopper is provided.
