Rotating the lead screw can move up and down. At the same time, since the lead screw only passes through the circular hole and the clamps are fixedly arranged on the lead screw, the upward movement of the lead screw drives the upward movement of the clamps, and then drives the upward movement of the horizontal plate, realizing the upward and downward movement of the limit ring and keeping stable when the lead screw does not rotate.
[0009] As preferred, the limiting ring comprises an outer ring and an inner ring, the inner ring is a rubber ring, the horizontal plate is fixedly arranged on the outer ring, the inner ring is a tapered structure with wide upper part and narrow lower part, and the inner ring is fixedly connected with the outer ring through the connecting rod, a plurality of notches are uniformly arranged on the side surface of the inner ring along the circumferential direction, and the notches penetrate the side surface of the inner ring downward.
[0010] As preferred, two clamping plates are symmetrically arranged in the through hole, the clamping plate is an arc shape outwardly protruding in the transverse section, and the clamping plate is fixedly connected with the inner wall of the through hole through the spring. The clamping plate can further clamp the test tube under the action of the spring, thereby further increasing the stability of the test tube.
[0011] As preferred, the inner side surface of the clamping plate and the bottom surface inner wall of the through hole are both bonded with shock-absorbing rubber pads, thereby better protecting the lower part of the test tube.
[0012] As preferred, the test tube storage rack further comprises vertical plates arranged on both sides of the top plate, the top plate and the bottom plate are both perpendicularly connected with the vertical plates, the outer side surface of the vertical plate is provided with a sliding block, and the inner wall of the cabinet body is provided with a sliding groove, and the sliding block is slidingly matched with the sliding groove. Thus, the test tube storage rack can be pulled out by pulling, thereby better taking the test tube.
[0013] The application has the advantages that: the upper and lower movement of the limiting ring can realize the limiting of the upper part of the test tube with different heights, thereby ensuring that the test tube can be vertically placed and preventing the test tube from being inclined and easily shaken, and thereby facilitating the orderly placement of the test tube.
