An under trimming device with inclinedly movable catchers for a multi-needle sewing machine with multiple longitudinally extended loopers comprises a cutting and clamping part, a fixed cutter, a plurality of looper assemblies and a thread push plate, characterized in that: the movable catcher of the cutting and clamping part and the looper form an angle of inclination such that when performing the thread cutting, the movable catcher extends toward the looper at an angle of inclination, and extends into the needle thread loop and the looper thread loop, and when the movable catcher returns to its initial position, the looper thread and the needle thread are cut off sequentially when they pass the fixed cutter, and the free end of the looper thread after being cut is still clamped between the leaf spring and the movable catcher, and the free ends of the cut needle threads are blown sideward in the opposite direction by an air blower to facilitate a next sewing.
