[0007] Preferably, a folding groove is opened on the lower surface of the support plate and near both sides, a No. 1 positioning groove is opened on the inner two end surfaces of the folding groove, a No. 2 positioning groove is opened on the inner upper surface of the folding groove and near both ends, and an axis groove is opened on the inner two side surfaces of the folding groove and near both ends.

[0008] Preferably, flip shafts are fixedly mounted on both side surfaces of the flip block, a stop groove is provided inside the flip block, one end of the flip shaft is movably embedded in the shaft groove, and the flip block is movably connected to the support plate via the flip shaft.

[0009] Preferably, a positioning column is fixedly mounted on the upper surface of the support rod, the upper end of the positioning column passes through the stop groove of the flip block and is embedded in the second positioning groove, and a stop ring is fixedly sleeved on the surface of the positioning column inside the stop groove.

[0010] Preferably, the diameter of the support rod is smaller than the inner diameter of the sleeve, and a spring is sleeved on the surface of the positioning column inside the stop groove and below the stop ring.

[0011] Preferably, the upper end of the spring is fixed to the stop ring, and the lower end of the spring is fixed to the inner lower surface of the stop groove.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In the utility model, by arranging the support plate, the support rod and the flip block to cooperate with each other, when the test tube stacking device is not in use, the support rod is pulled downward so that the positioning column of the support rod withdraws from the No. 2 positioning groove of the support plate. The support rod will compress the spring during the downward pulling process. When the positioning column of the support rod withdraws from the No. 2 positioning groove, the support rod is flipped so that the support rod is folded into the folding groove of the support plate. Finally, the external force pulling the support rod is released so that the positioning column of the support rod is embedded in the No. 1 positioning groove under the pushing action of the spring. In this way, the support rod can be kept in the state of being placed in the folding groove. When multiple unused test tube stacking devices are stacked together, more test tube stacking devices can be placed in the effective space. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-5A test tube stacking device is shown, comprising a support plate 1, a support rod 2 and a test tube stacking hole 4. The test tube stacking hole 4 is opened on the upper surface of the support plate 1, sleeves 5 are fixedly installed on the upper surface of the support plate 1 and near the four corners, and flip blocks 3 are movably installed on the lower surface of the support plate 1 and near the four corners, and a support rod 2 is provided below the flip block 3.

[0022] A folding groove 101 is provided on the lower surface of the support plate 1 and near both sides, a first positioning groove 102 is provided on the inner two end surfaces of the folding groove 101, a second positioning groove 103 is provided on the inner upper surface of the folding groove 101 and near both ends, an axis groove 104 is provided on the inner two side surfaces of the folding groove 101 and near both ends, and the folding groove 101 can store the support rod 2 when not in use; a flip shaft 301 is fixedly installed on the two side surfaces of the flip block 3, a stop groove 302 is provided inside the flip block 3, one end of the flip shaft 301 is movably embedded in the axis groove 104, the flip block 3 is movably connected to the support plate 1 through the flip shaft 301, and the flip shaft 301 can assist the flip block 3 to flip flexibly; the upper surface of the support rod 2 A positioning column 201 is fixedly installed on the surface, and the upper end of the positioning column 201 passes through the stop groove 302 of the flip block 3 and is embedded in the No. 2 positioning groove 103. The surface of the positioning column 201 located inside the stop groove 302 is fixedly sleeved with a stop ring 202. The cooperation between the positioning column 201 and the No. 2 positioning groove 103 can keep the support rod 2 in a vertical state; the diameter of the support rod 2 is smaller than the inner diameter of the sleeve 5, and a spring 203 is sleeved on the surface of the positioning column 201 located inside the stop groove 302 and below the stop ring 202, and the spring 203 has an upward thrust on the stop ring 202; the upper end of the spring 203 is fixed to the stop ring 202, and the lower end of the spring 203 is fixed to the inner lower surface of the stop groove 302.
