• wherein
• a main body of the testing block box assembly is a testing block box, the testing block box is an open box, a hole is provided in a bottom of the testing block box, an outer side of the hole is fixed with an annular member, an inner hole of the annular member is provided with inner threads and is centered with the inner hole of the annular member;
• symmetrical holes are provided on opposite sidewalls of the testing block box, an outer side of each of the symmetrical holes is fixed with an annular member, an inner hole of the annular member is provided with inner threads and is centered with the inner hole of the annular member;
• and the testing block box assembly further includes a fixing member, a placeholder member, and a stop member;
• the fixing member passes through the annular member on the sidewall of the testing block box from outside to inside and is threadedly connected to the inner hole of the annular member to fix a testing block in the testing block box in an opposite direction;
• and
• the placeholder member passes through the annular member at the bottom of the testing block box from outside to inside and is threadedly connected to the inner hole of the annular member;
• the stop member is removably attached to a portion of the placeholder member outside the box, and the stopper member is configured to prevent the placeholder member from screwing into the box;
• and
• the testing block box assembly further includes a spacer sheet lined between the testing block and the testing block box.
