[0049] When the 3D printer stops running, the electromagnetic suction block 207 is de-energized to release the adsorption of the iron block 209, at this time, the lifting block 2043, the lifting column 2046, the rubber base 2047 and the nozzle main body 1 move upward as a whole under the resetting elastic force of the return spring 2048, so that the nozzle main body 1 is stored in the frame composed of the side inverted concave seat 201 and the 7-shaped cover plate 202 again, and the protection effect is achieved.

[0050] Please refer to Figs. 1-5 , the top transverse part and the vertical part of the side inverted concave seat 201 are provided with a plurality of mounting holes 203 for connecting the side inverted concave seat 201 and the three-axis sliding table of the printer.
