[0031] In this embodiment, the heated aluminum rod is placed between the two frames 411, and then one of the main sliders 422 is driven to slide along the inside of the main slide 421 through the output end of the short-stroke cylinder 442. At the same time, the main slider 422 drives the auxiliary slider 426 to slide along the inside of the auxiliary slide 425 through the linkage assembly 43, and the protrusion 431 slides along the inside of the guide waist hole 412.
