In other embodiments, the second thimble 300 may be a polygon, and the embodiment of the present application uses a cylindrical second thimble 300 as an example.
The second ejector pin 300 is configured such that when the movable portion 100 moves along the first direction X, the second ejector pin 300 is first slid along the first direction X relative to the second ejector pin 300, and then driven to move along the first direction X, so that the first ejector pin 200 ejects the workpiece 30, and then the second ejector pin 300 ejects the scrap 40.

The movement travel B of the second ejector pin 300 along the first direction X satisfies: b is more than or equal to 10mm and less than or equal to 15mm. By way of example, second needle 300 may have a travel distance B in first direction X of 10mm, 11mm, 12mm, 13mm, 14mm, 15mm, etc. Because the movement of first ejector pin 200 precedes the movement of second ejector pin 300, the movement stroke A of first ejector pin 200 in first direction X is greater than the movement stroke B of second ejector pin 300 in first direction X, so as to reduce the stroke required for ejecting scrap 40.
