In a preferred embodiment of the spring 2, in order to facilitate the assembly, disassembly and replacement of the spring 2 on the housing 1, the bottom surface of the housing 1 is connected with a mounting tube 6. Specifically, the springs 2 are disposed in the mounting tube 6 and distributed along the axial direction of the mounting tube 6, and the mounting tube 6 is vertically connected to the bottom surface of the base 1, so that the extension direction of the springs 2 is still vertical. Accordingly, in order to ensure that the push rod 3 smoothly transmits the pressing pressure to the spring 2, in the present embodiment, the push rod 3 is integrally inserted into the base 1 and can vertically slide in the base 1. Meanwhile, the bottom end of the ejector rod 3 is connected with the top end of the spring 2. So set up, when ejector pin 3 kept the butt with the bottom surface of powder charge mould a, the pressure powder pressure of 5 outputs of pressing the medicine machine will promote ejector pin 3 and slide in frame 1 to on will pressing the medicine pressure to transmit the spring 2 in the installation section of thick bamboo 6 through ejector pin 3 simultaneously.
