The invention discloses a head transmission device of a computer jacquard ribbon loom. The head transmission device comprises a head wall plate; an electromagnetic valve presser is axially arranged onthe inner side of the head wall plate through an upper retaining plate; the electromagnetic valve presser is fixedly provided with an electromagnetic valve; the two outer sides of the head wall plateare respectively connected with rocker mechanisms through shafts; each rocker mechanism is also connected with a connecting rod mechanism for driving the rocker mechanism to move up and down; griffemechanisms which are vertically and horizontally oppositely distributed are correspondingly arranged at the position of the electromagnetic valve; the griffe mechanisms are axially staggered with respect to the connecting rod mechanisms; Not lifting the whole rocker mechanisms but lifting one ends of the rocker mechanisms is required here, more manpower is saved, working frequency is higher, and operating efficiency of the head transmission device can be increased by over 30%. In addition, compared with vertical up-down movement, rocker-type up-down movement takes less energy of the rocker mechanisms, with less abrasion caused to the head transmission device.
