Preferably: the limiting holes are formed in four corners of the surface of the fixed disc, internal threads are formed in the edge of a through hole in the middle of the fixed disc, external threads are formed in the circumferential surface of the movable rod below the pressing block, and the internal threads are matched with the external threads.
Preferably: the sliding blocks are arranged below the two sliding plates, sliding rails are arranged below the sliding blocks, the sliding blocks are limited in the sliding rails, the sliding rails are arranged in the inner cavity, and the fixed blocks and the two fixed plates are fixed on the sliding rails.
Preferably: the surface of the fixing frame body right below the limiting hole is provided with a corresponding hole.
Preferably: a plurality of support legs are arranged below the inner cavity, and each support leg is provided with a damping spring.
The utility model has the advantages that: the utility model discloses a fixed disk and press according to briquetting threaded connection, the fixed of the control test tube of being convenient for with take out, through installing the slipmat at slide and fixed plate surface, increase frictional force prevents that the test tube from sliding, thereby promotes the fixed test tube of slide through the power that extends that uses split form plastics, has avoided pressure to lead to the fact the cracked of test tube too big, through installing damping spring on the stabilizer blade, when the prevention takes place to vibrate, the test-tube rack takes place the phenomenon of turning on one's side.
