[0006] At least two clamping members are provided and symmetrically arranged on the inner wall of the hole. The clamping members abut against the outer surface of the test tube. The test tube is clamped by the clamping members, thereby improving the stability of the connection between the test tube and the orifice plate and avoiding shaking;

[0007] The side grooves are symmetrically arranged on the inner wall of the hole. The number of the side grooves is equal to that of the clamping members. The clamping members can be detachably installed in the side grooves, and the clamping members are placed through the side grooves.

[0008] Preferably, an integral protrusion is formed on the inner wall of the side groove, and the protrusion abuts against the side edge of the clamping member, thereby limiting the position of the clamping member and improving the stability of installation.

[0009] Preferably, the clamping member is a clamping bar, which is connected through the orifice plate at the upper middle position, and both sides of the clamping bar are concave and formed with arc grooves, and the protrusions are engaged and connected with the arc grooves.

[0011] Preferably, a bottom plate is further provided at the inner bottom end of the side plate, and the top end surface of the bottom plate overlaps with the bottom end surface of the test tube to support the bottom of the test tube.

[0012] Preferably, a base frame is provided at the bottom end of the two side panels, and both ends of the base frame are bent downward to form a hook shape, and a connecting block is placed on the inner side of the hook. The height of the connecting block is equal to the distance between the bottom plate and the inner side surface of the hook. Therefore, when the base frame is installed with the side panel, the connecting block will be simultaneously tightened and limited. A suction cup is installed on the bottom end surface of the connecting block, and the bottom end surface of the suction cup is lower than the bottom end surface of the base frame.
