[0025] like Figure 3 and Figure 5 As shown: the bottom of multiple ejector rods 17 is fixedly connected to a support plate 18, the bottom of the support plate 18 contacts the top of multiple load-bearing blocks 15, the top of multiple ejector blocks 16 contacts the inner wall of the shell 6, the bottom of the support plate 18 is fixedly connected to a plurality of slide rods 19, the outside of the slide rod 19 is slidably connected to a sleeve 20 for protecting the internal structure, the outside of the sleeve 20 is sleeved with a spring 21 for storing elastic potential energy to provide power for the structures at both ends, one end of the spring 21 is fixedly connected to the bottom of the support plate 18, the other end of the spring 21 is fixedly connected to the bottom of the inner wall of the moving plate 4, the right side of the outside of the shell 6 is fixedly connected to a cylinder 22, the driving end of the cylinder 22 is fixedly connected to a telescopic push rod 23, the left side of the outside of the telescopic push rod 23 is fixedly connected to a push plate 24, the top of multiple fixed columns 5 is fixedly connected to a top plate 25, and the top of the top plate 25 is fixedly connected to a feeder 26.
