The invention relates to the field of electronic jacquard machines and discloses a time difference electromagnet jacquard warp-selecting mechanism. The time difference electromagnet jacquard warp-selecting mechanism comprises a base plate, an electromagnet, two swinging hooks and two warp-lifting hooks, wherein the electromagnet is arranged at the upper end of the base plate, the two swinging hooks are arranged on two sides of the electromagnet, and the two warp-lifting hooks move up and down on guide rails of the base plate. The multi-selection type electromagnet jacquard warp-selecting mechanism is characterized by further comprising a left lifting knife and a right lifting knife, wherein the left lifting knife and the right lifting knife are located below a left warp-lifting hook and a right warp-lifting hook respectively and do up-down reciprocating motion; the distance from the left lifting knife to the right lifting knife is changed between 0 and H during the motion; each of the left warp-lifting hook and the right warp-lifting hook is connected with a warp-lifting rope; the two swinging hooks and the two warp-lifting hooks are selectively hung up or not. According to the time difference electromagnet jacquard warp-selecting mechanism, a complex wheel slippage structure in an existing warp-selecting mechanism is omitted, each warp-lifting hook is connected with one warp-lifting rope, and one electromagnet is shared by the two swinging hooks of each warp-selecting mechanism and is discontinuously powered so as to select whether to lift two warps, so that the size of the mechanism is halved, the functions are doubled, and the cost is effectively saved.
