At this time, the bead seat 210 can restrict the displacement of the elastic bead assembly 420, thereby restricting the displacement of the recovery case 200. Thereby, the stability of the recovery box 200 is further improved.

As shown in fig. 4, in one embodiment of the present utility model, the recycling bin 200 further includes: two sets of first circular arc plates 220 and second circular arc plates 230. Wherein, two groups of the first arc plates 220 are oppositely arranged at the edge of the opening of the recovery box 200, one group of the first arc plates 220 is connected with the nozzle of the placing cylinder 300, and the inner side surface of the first arc plates 220 is away from the opening of the recovery box 200; the second arc plate 230 is disposed at the edge of the opening of the recovery box 200 and is connected with the nozzle of the placement cylinder 300, the length of the second arc plate 230 is smaller than that of the first arc plate 220, and the inner side faces deviate from the opening of the recovery box 200.

Specifically, by providing two sets of the first circular arc plate 220 and the second circular arc plate 230 having inner sides facing away from the opening of the recovery box 200 at the opening edge of the recovery box 200, respectively, the area of the grip portion is increased, and the recovery box 200 can be conveniently taken out when being emptied and recovered. In addition, the length of the second circular arc plate 230 disposed close to the recovery cylinder is smaller than that of the first circular arc plate 220, so that the sample liquid can be prevented from being spilled out due to collision with the second circular arc plate 230 when the waste pipetting head is thrown into the recovery box 200, and the safety is further improved.

In a preferred embodiment of the utility model, as shown in fig. 4, three guide blocks 310 are provided at the nozzle of the placement barrel 300 extending in a direction away from the nozzle. That is, the guide block 310 can guide the position of the pipette tip when inserting the pipette tip with the cap into the placement barrel 300. Therefore, the position error of the pipetting head can be avoided, and the sample liquid is prevented from being scattered.

As shown in fig. 4, in one embodiment of the present utility model, the bottom of the placement barrel 300 is formed with an opening communicating with the accommodation chamber of the recovery box 200. That is, after the pipette tip with the cap opened is inserted into the placement cylinder 300, the sample liquid dropped from the swab cap on the top of the pipette tip can flow into the receiving chamber in the recovery box 200 through the opening in the bottom of the placement cylinder 300. Thus, the liquid improves the recovery efficiency of the recovery cartridge 200 while avoiding accumulation of the sample liquid in the placement cylinder 300.
