The pipette rack top plate 1 is provided with a plurality of pipette holes 11 and ear washing ball holes 12 in a row along the front and rear sides of the length direction thereof. A plurality of ear washing balls can be connected to the pipette rack top plate 1 through the ear washing ball holes 12 to meet the placement of a plurality of ear washing balls, and a plurality of pipettes can be inserted into the corresponding pipette holes 11 accordingly; it should be noted that the diameters of the pipette holes 11 and the ear washing ball holes 12 can be set according to the requirements to meet the requirements. A plurality of label pasting areas 14 are provided on the front side of the pipette rack top plate 1 in correspondence with the pipette holes 11, and each label pasting area 14 can correspond to a label, and the pipettes corresponding to different solutions can be distinguished through the label pasting area 14.

[0026] like Figure 1~2 As shown, a plurality of snap-in strips 22 are provided at the top end of the supporting spine 2 along its length direction, and a plurality of first positioning slots 13 are opened at equal intervals along its length direction on the top plate 1 of the tube rack; in this embodiment, the first positioning slots 13 are distributed between the pipette position hole 11 and the ear cleaning ball position hole 12, and the upper end of the supporting spine 2 can be connected to the first positioning slot 13 of the top plate 1 of the tube rack through the snap-in strip 22; so that the ear cleaning ball and the pipette are distributed on the front and rear sides of the supporting spine 2, so as to facilitate maintaining the balance of the pipette rack during use.

[0027] like Figure 2~3As shown, a long plug-in hole 21 is provided at the lower part of the support ridge plate 2; in this embodiment, multiple layers of long plug-in holes 21 are provided at the lower part of the support ridge plate 2, and each layer of long plug-in holes 21 includes two. The support bottom plate 3 includes a support plate 31 and a support back plate 33 fixedly connected to the back side of the support plate 31. Two support back plates 33 are provided on the back side of the support plate 31. The support back plates 33 can be inserted into the long plug-in holes 21 correspondingly, so that the inner side of the support plate 31 is in contact with the support ridge plate 2 to form a support structure; the support plate 31 is provided with multiple pipette clamping holes 32 along its length direction corresponding to the pipette position hole 11. The pipette clamping hole 32 can be a tapered hole with a larger top and a smaller bottom that matches the shape of the lower end detail of the pipette, so as to facilitate the stable clamping of the lower end detail of the pipette. The long plug-in holes 21 arranged in layers on the supporting spine 2 can meet the plug-in position of the supporting base plate 3, so as to meet the placement requirements of pipettes of different lengths; the two long plug-in holes 21 arranged in each layer can improve the plug-in stability of the supporting base plate 3 and the supporting spine 2; after multiple pipettes are inserted into the pipette position holes 11, the thin parts of their lower ends can be correspondingly inserted into the pipette clamping holes 32 of the supporting support plate 31, thereby forming a stable support for the pipette and facilitating the discharge of residual liquid in the pipette.
