PURPOSE: A different type parts gripper is provided to allow for ease of nozzle replacement and achieve improved coupling force. CONSTITUTION: A different type parts gripper(100) comprises a socket unit(200) and a holder unit(300). The socket unit includes a coupling block(220) for coupling with a hollow shaft(210); a connection block(230) having a holder insertion portion; socket shafts(240,241) for locking the holder inserted into the holder insertion portion of the connection block; and elastic members(250) for elastically supporting the socket shafts. The holder unit includes a holder(310) in which the hollow shaft is inserted; and a holder shaft(320) having an air passage. The connection block has a plurality of socket shaft insertion portions(231) each of which has a first inclined portion and a second inclined portion having an angle of 0 to 60 degrees. The holder of the holder unit includes a plurality of first inclined surfaces(311,312) formed in the upper portion of the holder; a plurality of second inclined surfaces(313,314) for permitting the socket shafts to slide when the first inclined surfaces slide with respect to tapers(232a,232b); and a plurality of third inclined surfaces(315,316) formed in the lower portion of the holder.
