Unless stated to the contrary, these orientation words do not indicate or imply that the apparatus or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as limiting the scope of protection of the invention. The orientation words "inside and outside" refer to inside and outside relative to the outline of each part itself.

For ease of description, spatially relative terms, such as "over", "above", "on the surface", "upper", etc., may be used herein to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figures. It should be understood that the spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the devices in the accompanying drawings are inverted, those described as "above other devices or structures" or "over other devices or structures" will then be positioned as "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above" may include both "above" and "below" orientations. The device may also be positioned in various other ways (rotated <NUM> degrees or at other orientations) and the spatially relative descriptions used herein are interpreted accordingly.

Furthermore, it is to be noted that the use of the words "first", "second" and the like to define parts is only for the convenience of distinguishing the corresponding parts, unless otherwise stated, the words have no special meaning, and therefore cannot be construed as limiting the scope of protection of the invention.

Claim 1:
A to-be-tested object processing apparatus, comprising:
a frame body (<NUM>), provided with a sample processing platform (<NUM>);
an extraction mechanism (<NUM>), configured to extract an analyte in a to-be-tested object;
a grabbing part (<NUM>), movably arranged above the sample processing platform (<NUM>) in a vertical direction and a first horizontal direction;
a transfer part (<NUM>), movably arranged on the sample processing platform (<NUM>) in a second horizontal direction perpendicular to the first horizontal direction, the transfer part (<NUM>) comprising an extraction plate transfer part (<NUM>), the extraction plate transfer part (<NUM>) being provided with a first transfer position where the extraction plate transfer part (<NUM>)moving to below the grabbing part (<NUM>), the grabbing part (<NUM>) being provided with a first grabbing position located above the extraction plate transfer part (<NUM>) and a second grabbing position located above the extraction mechanism (<NUM>), and when the extraction plate transfer part (<NUM>) is located in the first transfer position, the grabbing part (<NUM>) being able to move between the first grabbing position and the second grabbing position to move an extraction plate between the extraction plate transfer part (<NUM>) and the extraction mechanism (<NUM>); and
a pipetting part (<NUM>), movably arranged above the sample processing platform (<NUM>);
wherein the extraction plate transfer part (<NUM>) is further provided with a sample adding position corresponding to the pipetting part (<NUM>), and when the extraction plate transfer part (<NUM>) is located in the sample adding position, the pipetting part (<NUM>) is further provided with a first pipetting position where the pipetting part (<NUM>)moving to above the extraction plate transfer part (<NUM>).
