Embodiment approach
[0041] As an embodiment of the present invention, the limiting hole 52 is a tapered hole, and one end of the elastic plug 5 is set in a tapered shape. Reduce the stress of the pull rope 33 when pulling the elastic plug 5 through the limiting hole 52, improve the service life of the pull rope 33, thereby increase the stability of the equipment, facilitate a large number of repeated tests, and improve the efficiency of the experiment.
[0042] As an embodiment of the present invention, the outer ring of the pressing column 31 is covered with the annular airbag 6; the buffer hole 13 is fixedly connected with an annular support airbag 61, and the support airbag 61 communicates with the annular airbag 6, so that The thickness of the elastic piece 25 is smaller than the thickness of the coin. When pushing the pressing column 31, the annular airbag 6 is pressed and supplies air to the support airbag 61. After the annular support airbag 61 is inflated, the coin in the buffer hole 13 i...
