PURPOSE: To execute safe and sure locking by providing the device with locking means housed in a chuck plate and a recessed part which has a locking ring and is used to accept the locking means. CONSTITUTION: A blood centrifugation cell 2 and the locking ring 3 are first arranged in contact with the locking machine system in the holes 13, 14 and 15 of the chuck plate 1 by elastic locators. A cylindrical body 16 is held within the plate by suitable screwing into the holes 13, 14 and 15 and spherical bodies project by a slight distance from the peripheral edge of the chuck plate. At the time the locking ring 3 slides on the peripheral edge of the chuck plate, the bottom end of the ring presses the spherical bodies 17 against springs 18 in the plate. When the groove holes 10, 11 and 12 of the ring are in proximity to the elastic locators, the spherical balls 17 are pushed into the groove holes and the cell and the ring are mounted on the chuck plate. As a result, the locking of the plate to the cell is automatically executed. |
