[0032] Specifically, the tube limiting rod 32 and the lock rod piece 33 are arranged on the test tube rack 3, after the test tube is placed on the test tube rack 3, the tube limiting rod 32 is clamped tightly by pressing down, and the end of the tube limiting rod 32 is clamped into the lock rod piece 33, so that the test tube is fixed.

[0033] In this way, by setting the tube limiting rod 32 and the locking rod piece 33, multiple test tubes are fixed at the same time, improving the efficiency of test tube disassembly and assembly. In the existing cell homogenizer, the structure of the U-shaped elastic sheet is often used. If the force is too large during pressing, it may collide with the hand. By setting the tube limiting rod 32 and the locking rod piece 33, multiple test tubes are locked at the same time, reducing the operation risk.

[0034] In some feasible ways, the driving module 1 is part of the prior art, which will not be described here.
