[0032] See attached Figure 2 The co-extrusion assembly 2 includes two first fixed plates 21, which are fixedly connected to the bottom surface of the table 1, and the opposite sides of the two first fixed plates 21 are fixedly connected to two slide rail columns 22. The two slide rail columns 22 are respectively connected to two springs 24, and the two springs 24 are fixedly connected between the two sliding plates 23.
[0033] Furthermore, the two sliding plates 23 are socketed with the two slide rail columns 22 through the two first circular holes, and the opposite sides of the two sliding plates 23 are fixedly connected with the two push plates 25 respectively. The two push plates 25 are arranged in a symmetrical L-shape, and the two push plates 25 are respectively socketed with the first rectangular holes opened on the two first fixed plates 21.
[0034] According to the above structure, the two trimming components 3 are pushed away from each other, thereby driving the spring 24 on the extrusion component 2 to stretch and generate elastic tension, and then pulling the sliding frame 54 on the expansion component 5 to slide upward, so that the sliding frame 54 drives the four expansion connecting rods 55 to shrink on the side of the rotating plate 53, and then the plastic product is put on the expansion connecting rod 55, and the sliding frame 54 is released, so that the sliding frame 54 slides down by its own weight and pushes the four expansion connecting rods 55 to flip and expand and press against the inner side of the plastic product to form a fixation, so that the plastic product can be clamped on the expansion component 5.
[0035] See attached Figure 3 and attached Figure 4The two trimming components 3 both include a sliding plate 31, which is sleeved with the push plate 25 through the second rectangular hole, and the sliding plate 31 is fixedly connected to the lifting plate 38, which is sleeved with the push plate 7 through the third rectangular hole.
