When the mounting beam 32 is in the working position, the stopper structure 60 is located at the stop position to support the receiving plate structure 20. In the above structure, when the recovery rod 34 is connected to the magnetic rod sleeve 90, the magnetic rod sleeve 90 needs to be pressed downward to fix the magnetic rod sleeve 90 to the recovery rod 34 with a tightening margin, so that the receiving plate structure 20 needs to receive the pressing force of the recovery rod 34.

[0032] In addition, the drive motor 61 and the receiving plate structure 20 are located on a first side of the vertical plate 12, the rotating shaft of the drive motor 61 passes through the vertical plate 12 and extends to a second side of the vertical plate 12, a first end of the oscillating member 62 is located on the second side of the vertical plate 12 and is drivingly connected to the rotating shaft of the drive motor 61, and a support rod 621 is provided at a second end of the oscillating member 62, and the support rod 621 enters the first side of the vertical plate 12 through an arc-shaped guide groove 121 to form a stopper cooperation with the receiving plate structure 20.

In the above structure, since the retrieval rod 34 needs to engage with the magnetic rod sleeve 90, the diameter of the first rod portion 341 is increased and a diameter-changing portion is provided in the first rod portion 341, so that the retrieval rod 34 can be easily inserted into the magnetic rod sleeve 90. In addition, the diameter of the second rod portion 342 is reduced, so that the second rod portion 342 can be smoothly inserted into the nucleic acid extraction plate 100.

[0038] As shown in FIG. 6, the bottom of the second rod portion 342 has a plurality of notches 3421, which ensures that when the bottom of the second rod portion 342 comes into contact with the inner wall of the nucleic acid extraction plate 100, the air flow path is not blocked and the waste liquid within the nucleic acid extraction plate 100 can be cleanly sucked out.

[0039] The present application further provides a nucleic acid detection and analysis device, and an embodiment of the nucleic acid detection and analysis device includes a consumables recovery device, which is the above-mentioned consumables recovery device.

[0040] In describing the present invention, it should be understood that orientations or positional relationships indicated by directional terms such as "front, back, up, down, left, right", "sideways, lengthways, vertical, horizontal", "top, bottom" and the like are generally based on orientations or positional relationships shown in the drawings, and are merely for the purpose of making the present invention easier to describe and simplifying the description, and that, unless otherwise stated, these directional terms do not indicate or imply that the devices or elements shown have a particular orientation or must be configured and operated in a particular orientation, and therefore should not be understood as limiting the scope of protection of the present invention. Also, the directional terms "inside, outside" refer to the inside and outside of the contour of each member itself.

[0041] For purposes of explanation, spatially relative terms, such as "on...," "above...," "on top of...," "above," and the like, may be used herein to describe the spatial location of a device or feature as depicted in the figures relative to other devices or features. It should be understood that spatially relative terms are intended to include different orientations of use or operation of the device other than the depicted orientation. For example, if a device in the drawings is inverted, a device described as "above other devices or structures" or "on top of other devices or structures" would be described as "below other devices or structures" or "under other devices or structures" after being inverted. Thus, the illustrative term "above..." can include two orientations: "above..." and "below...." The device may be positioned in other different ways (rotated 90 degrees or at other orientations) and the spatially relative descriptions used herein should be interpreted accordingly.

[0042] In addition, the use of terms such as "first" and "second" to define parts is merely for the purpose of making it easier to distinguish corresponding parts. Unless otherwise explained, the above terms have no special meaning and should not be understood as limiting the scope of protection of the present invention.

[0043] The above is merely a preferred embodiment of the present invention, and is not intended to limit the present invention. Those skilled in the art can make various modifications and variations to the present invention. Any modifications, equivalent replacements, improvements, etc. within the spirit and principle of the present invention should be included within the protection scope of the present invention.
