1. A die test pressing-down apparatus, comprising:
a support frame capable of moving along a vertical direction; and
a pressing-down block installed on the support frame, wherein a part to-be-pressed is disposed directly below the pressing-down block, wherein:
the pressing-down block is connected to the support frame through an installation plate; a strip-shaped through hole is formed at an upper surface of the support frame; a first protruding strip is at each of lower portions of two opposite inner walls of the strip-shaped through hole; a corresponding second protruding strip extending directly above the first protruding strip is at each of upper portions of two opposite side surfaces of the installation plate; a strip-shaped block is disposed above each second protruding strip; and a side of the strip-shaped block is fixedly connected to the upper surface of the support frame, and another side of the strip-shaped block extends to directly above the second protruding strip and is connected to the second protruding strip through at least two springs; and
when the pressing-down block and the part to-be-pressed are spaced apart from each other, a lower surface of the second protruding strip is adjoined to be in a contact with an upper surface of a corresponding first protruding strip; and when a lower surface of the pressing-down block is tightly pressed with an upper surface of the part to-be-pressed, a gap is formed between the lower surface of the second protruding strip and the upper surface of the corresponding first protruding strip.
