[0006] The utility model with the above characteristics: the filter is externally arranged, and the setting of the transparent sleeve makes the filter visible, so that the use status of the filter can be easily observed and whether it needs to be cleaned or replaced.

[0007] A further configuration of the utility model is that sealing rings are provided between the two ends of the transparent sleeve and the first connecting seat and the second connecting seat respectively.

[0008] The utility model with the above characteristics: the sealing ring realizes the sealing installation of the transparent sleeve.

[0009] A further configuration of the utility model is that the mounting portion is connected to the oil inlet end through threaded fitting.

[0010] The utility model with the above characteristics: the threaded fitting is convenient for disassembly.

[0011] A further configuration of the utility model is that the filter elements at the oil inlet ends are connected via threaded fitting.

[0012] The utility model with the above characteristics: the threaded fitting is convenient for disassembly.

[0013] The beneficial effect of the utility model is that the transparent sleeve is provided, so that the amount of filter residue accumulated in the filter screen can be clearly seen, and can be cleaned or replaced in time to ensure that the oil path is unobstructed.
