Preferably, the upper end of the hanging plate is equipped with rubber layer.

Preferably, the test tube clamp includes two clamping sections, and torsional spring, the both ends difference of torsional spring are set between two clamping sections Bending is set to hook two clamping sections, for providing the clamping force of test tube clamp.

Preferably, the test tube clamp integral thickness is uniform, and a clamping section is longer, and the mounting groove is arranged on the longer folder In tight portion.

By adopting the above-described technical solution, the present invention has the advantages that：

1. hung over directly by test tube together with rack for test tube on hanging plate can, pick and place conveniently, rack for test tube be installed to Can amount transport on loading plate；

2. having lockplate, can prevent test tube clamp from deviating from when moving rack for test tube, during under the clamping force of test tube clamp, Test tube will not collide with other objects；

3. rubber layer can increase frictional force, prevent test tube clamp from moving, and there is certain cushioning effect.
