Abstract

The utility model relates to a mainboard testing device. The test module comprises a base, a plurality of fixing blocks and a test card, wherein, the lower part of the base can be used for arranging the fixing blocks. The upper part of the base is provided with rows of positioning holes. A plurality of long grooves are horizontally arranged at the point near each row of the long grooves. Positioning holes are arranged above each of the fixing blocks. The lower parts of the fixing blocks can be assembled with the test card. More than one positioning segmental hole is respectively arranged on both side of the test card. Positioning segmental holes can be used for bolts, and each of the positioning segmental holes can be chosen for each of the bolt. The bolts penetrate into horizontally through holes of the fixing blocks to fix the test card. Screws can be fixedly locked outside the holes between the base and the fixing blocks by means of the fixing blocks of the test module. The screw can also penetrate in the long grooves of the base. An exact positioning point is selected for combination and fixed lock. The arranged positions of the fixing blocks can be matched with the memory inserting grooves to regulate and move the fixing blocks. Moreover, the arranged height of the test card can be selected according to the positioning segmental hole of the test card so that the test module can give full play to the perfect testing performance.
