[0018] The beneficial effects of the utility model are:

[0019] The top of the ejector pin is plugged into the bottom of the card block, and the bottom of the ejector pin is fitted with the first clamping block. The handle screw is then rotated to clamp and fix the bottom of the ejector pin in the placement groove of the base. The push rod motor is then extended downward to drive the pressing block to squeeze the top of the card block. The pressure borne by the ejector pin is detected by a weighing sensor, and the value is displayed by a digital display.
