[0030] In specific implementation, since the inkjet printer nozzle needs to be disassembled and repaired regularly, but most of the inkjet printer nozzles are not convenient to disassemble, when disassembling the nozzle, the push rod 905 can be rotated to make the push rod 905 and the lower cover plate 2 threadedly meshed and push the limit block 903 to one side, so that the limit block 903 squeezes the return spring 901 to contract, and then the upper cover plate 1 is pulled upward, the upper cover plate 1 and the lower cover plate 2 can be quickly disassembled, which is convenient for repairing the inside of the nozzle, and the setting of the limit block 903 is convenient for installation, which improves the convenience of the inkjet printer nozzle.
