It is noted that, can play the effect of centering the location to the bottom of small sample pipe through the center back taper hole, avoid small sample pipe bottom to take place the skew.

Specifically, in the embodiment of the utility model, the support leg 2 is hinged with a bracket hinge point 1.1 on the bracket 1 through a support leg hinge point 2.1.

Specifically, in the embodiment of the utility model, the supporting leg 2 is provided with a supporting leg hook 2.2, and the supporting leg hook 2.2 is used for limiting the movement of the elastic ring 3 relative to the supporting leg 2.

Specifically, in the specific embodiment of the present utility model, the leg hook 2.2 is of a concave structure or a convex structure; the number of the supporting leg hooks 2.2 is 1-10 on the single supporting leg 2; the number of the elastic rings 3 is consistent with that of the supporting leg hooks 2.2.

Specifically, in the embodiment of the present utility model, the end of the leg 2 away from the bracket 1 is provided with a leg arc surface 2.3, and the leg arc surface 2.3 is used to abut against the sample tube 4.

It should be noted that the stability of sample tube access can be improved by the arcuate surface of the leg.

In particular, in a specific embodiment of the present utility model, the elastic ring 3 is one or more of an O-shaped rubber ring, a rubber band or a spring ring.

Specifically, in the embodiment of the present utility model, the elastic ring 3 is an elastic ring made of silica gel, rubber or stainless steel spring steel.

Specifically, in the embodiment of the present utility model, the supporting leg 2 is a plastic or metal supporting leg.

Specifically, in the specific embodiment of the present utility model, the number of the supporting legs 2 is 2-30.

Specifically, in a specific embodiment of the utility model, the end of the leg 2 remote from the bracket 1 is provided with a first magnetic portion 5.1; the bracket 1 is provided with a second magnetic part 5.2; the second magnetic part 5.2 is consistent with the first magnetic part 5.1 in horizontal height; the second magnetic part 5.2 and the first magnetic part 5.1 are in homopolar repulsive state.

It should be noted that, the elastic ring can provide a relatively constant clamping force for the sample tube, but for a large sample tube, the sample mass of the sample tube is much greater than that of a small sample tube; that is, for large sample tubes, the clamping force provided by the legs that it requires to maintain stability will be greater than that required for small sample tubes.

Through setting up the homopolar state of repulsing of first magnetic part and second magnetic part, can make when putting into big sample tube, trigger the magnetism repulsion between first magnetic part and the second magnetic part, increase the landing leg to the holding power of sample tube. Meanwhile, as the size of the sample tube increases, the larger the repulsive magnetic force between the first magnetic portion and the second magnetic portion, the larger the holding force of the leg to the sample tube, and the larger the sample tube can be clamped.

The reaction force of the first magnetic part to the third magnetic part can buffer the sample tube in the process of placing the sample tube by matching the plurality of third magnetic parts with the first magnetic part; further, as the first magnetic part and the third magnetic part have repulsion, the sample tube has the effect of gear engagement in the process of being put into, so that the circumferential positioning of the sample tube is performed, and the characteristic of preventing the sample tube from rotating is realized; furthermore, the support legs have certain friction force on the sample tube, and certain resistance is realized when the sample tube is directly taken out, and when the sample tube is taken out under the repulsive magnetic action of the first magnetic part and the third magnetic part, the support legs can be spirally arranged by rotating the sample tube, so that the acting force of the support legs on the sample tube is reduced, the resistance when the sample tube is taken out is further reduced, and the sample tube is conveniently taken out; further, due to the repulsive force between the first magnetic part and the third magnetic part, when the sample tube is lifted, the sample tube has upward acting force, so that the sample tube is lifted lightly, and the sample tube is taken conveniently. It should be noted that, by the repulsive action of the third magnetic portion and the first magnetic portion, the convenience and functionality of the sample tube in the three processes of putting in, storing and taking out are improved.

It should be noted that the prior art (see fig. 1: original elastic tube support) has defects or shortcomings: the spring piece or the spring steel wire is adopted as an elastic body (the elastic sheet 6), automatic centering is achieved through the elasticity of the spring, and the elastic pipe support adopting the mode has the main defects that when the diameter of a sample pipe is smaller, the elastic deformation of the spring piece or the spring steel wire is small, so that the elasticity is insufficient, and the centering effect cannot be achieved; when the diameter of the sample tube is larger, the elastic deformation of the spring piece or the spring steel wire is large, so that the elasticity is excessive, the resistance of the sample tube is excessive, and even the label on the wall of the sample tube is scratched; the flexible tube support in this form is therefore only suitable for applications where the diameter range of the compatible sample tube is relatively small (typically within 10 mm) and the sample tube height difference is also relatively small.

It should be noted that the present technology provides a sample tube holder device compatible with multiple sample tubes, where the holder is a circular container larger than the maximum tube diameter required to be compatible, and is divided into an upper layer and a lower layer, the upper layer is used for placing a relatively thick sample tube, and the lower layer is used for placing a relatively thin sample tube, and can be well adapted to a sample tube with a circular arc bottom.

The elastic ring 3 can be independently placed into one or more elastic rings according to the specific condition of the sample tube so as to achieve the optimal effects of elasticity and centering.

The bracket 1 is divided into an upper layer and a lower layer, so that the bracket is more compatible with a sample tube with an elongated tube and an arc bottom, and has wider application range; 2 support leg hooks are arranged on the support leg 2 in a segmented mode, and elastic rings 3 with different elastic forces can be placed selectively, so that the optimal centering effect on the sample tube 4 can be achieved through the appropriate elastic force.

It should be added that the first bracket 1: the support function in the whole structure, the bracket inner cavity can be round, square or multiparty, and the material is plastic or metal.
