7. The two-pass oil filter joint as claimed in claim 1, wherein the diameter of the outer side of the adjusting pipe is equal to the diameter of the inner wall of the screen.
8. The two-channel oil filtering joint as claimed in claim 7, wherein the adjusting pipe is designed to cooperate with a disc spring and a limiting ring, and the limiting ring cooperates with the disc spring to limit and adjust the adjusting pipe, so as to adjust and fix the position of the adjusting pipe in the screen pipe as required.
9. The two-way oil filter joint as claimed in claim 8, wherein the adjusting pipe is designed to match with the sieve pipe and the waist-shaped hole, and the adjusting pipe and the sieve pipe can be adjusted in a staggered manner by changing the relative positions of the adjusting pipe and the sieve pipe, so as to change the filter aperture.
10. The two-channel oil filter joint according to claim 1, wherein the adjusting screw sleeve is screwed, the adjusting screw sleeve drives the limiting ring to move at the opening of the connecting pipe, the disc spring is matched with the movement of the limiting ring to support and adjust the adjusting pipe, so that the position between the adjusting pipe and the sieve pipe is relatively changed, and further the positions of the waist-shaped holes on the adjusting pipe and the sieve pipe are relatively adjusted to change the aperture of the filtering hole.
