Rotating device for biological detection

A rotating device for biological detection and detecting a detecting disc, comprising:

• a rotating shaft;
• a motor for rotating the rotating shaft;
• a rotating disc formed in a circular shape, a center of the rotating disc being fixed on the rotating shaft, the rotating disc being rotatable along with the rotating shaft, and an engaging protrusion being disposed on a periphery of the rotating disc;
• a left clamping disc located above the rotating disc, the left clamping disc being formed in a semi-circular shape, a center of a diametric side of the left clamping disc being sleeved on the rotating disc, the left clamping disc being rotatable relative to the rotating disc, and a density of the left clamping disc being half of a density of the detecting disc;
• a right clamping disc located above the rotating disc, the right clamping disc being formed in a semi-circular shape, a center of a diametric side of the right clamping disc being sleeved on the rotating disc, the right clamping disc being rotatable relative to the rotating disc, and a density of the right clamping disc being half of a density of the detecting disc;
• an upper clamping disc sleeved on the rotating shaft and rotatable along with the rotating disc, the upper clamping disc fixing the rotating disc, the left clamping disc, and the right clamping disc on the rotating shaft;
• and
• a recovering component abutting between a side of the left clamping disc and a side of the right clamping disc for driving the other side of the left clamping disc and the other side of the right clamping disc to move toward each other;
• wherein a clamping zone is formed between the other side of the left clamping disc and the other side of the right clamping disc for clamping the detecting disc, a part of the left clamping disc overlaps a part of the right clamping disc to form an overlapping zone, and the overlapping zone is formed between the side of the left clamping disc and the side of the right clamping disc and opposite to the clamping zone.
