At this time, the molding nozzle 5 can be pulled out; when the molding nozzle 5 is taken out, the second spring 9 extends and pushes the second push block 8 to move outward, and the second push block 8 abuts against the fixing rod. At this time, the pulling plate can be released, and when it is installed again, the molding nozzle 5 is movably sleeved on the fixing tube 25, and the molding nozzle 5 is rotated to drive the first push block 6 into the movable box until the first push block 6 pushes the second push block 8 to compress the second spring 9. When the fixing hole on the first push block 6 is aligned with the fixing rod, the first spring 7 recovers and drives the fixing rod into the fixing hole through the pulling plate, and the installation of the molding nozzle 5 can be achieved.
