description The utility model provides a compound needle of a warp knitting machine. The compound needle comprises a groove needle and a needle core. The groove pin comprises a pin head, a pin rod and a pin foot. The needle core comprises a needle core head portion, a transition portion and a needle core root portion. The groove pin and the pin core move in a matched mode. The back of the groove pin is linear, and the turning position of a pin rod is a large arc transition part. The length of the needle rod is reduced, and rigidity is improved. And the needle rod is thickened, so that the strength of the needle rod is improved. A needle groove is formed in the front side of the groove needle rod, and a notch of the needle groove extends downwards to the tail of the large arc transition part so as to ensure that the relative stroke of the needle core is increased. The inner arc of the needle core transition part is an acute angle, and the needle core block does not interfere with the groove needle in the warp knitting loo
