Abstract
A quick release print head includes a heating block, a nozzle tube and a connecting tube. The nozzle tube is inserted in the heating block. One end of the nozzle tube has a nozzle and the other end is extended with an extension tube exposed to the heating block. The connecting tube is connected with the extension tube. Whereby, the extension tube extended from the nozzle tune is exposed to the heating block so that the nozzle tube disposed near the heating block cannot be disassembled. Thus a process of replacing components by heating a nozzle can be bypassed, and advantages of quick disassembly and easy maintenance of the print head can be achieved.

A print head with quick release mechanism, including:
- a heating block;
- a nozzle tube inserted in the heating block;
- one end of the nozzle tube having a nozzle and the other end extending to form an extension tube exposed to the heating block;
- a connecting tube connected with the extension tube, wherein an inner peripheral surface of the heating block has first internal threads, and an outer peripheral surface of the nozzle tube has first external threads;
- the first internal threads and the first external threads are screwed together;
- and
