## Abstract

A rotating device includes a rotating shaft, a rotating disc, a left clamping disc, a right clamping disc, an upper clamping disc, and a recovering component. The upper clamping disc, the left clamping disc, and the right clamping disc are sleeved on the rotating shaft. The upper clamping disc fixes the rotating disc, the left clamping disc, and the right clamping disc on the rotating shaft. The recovering component abuts between a side of the left clamping disc and a side of the right clamping disc. 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, and an 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.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The rotating device of claim 1, wherein the detecting disc is a circular sector corresponding to the periphery of the rotating disc, and at least one testing channel is formed on the detecting disc.

### Claim 3 (depends on 2)

The rotating device of claim 2, wherein the entire rotating disc is transparent.

### Claim 4 (depends on 2)

The rotating device of claim 2, wherein at least one part of the rotating disc corresponding to the at least one testing channel is transparent or hollow.

### Claim 5 (depends on 1)

The rotating device of claim 1, wherein the recovering component is a spring.

### Claim 6 (depends on 1)

The rotating device of claim 1, wherein the engaging protrusion is disposed on a center of an outer periphery of the clamping zone for engaging with an outer periphery of the detecting disc.

### Claim 7 (depends on 6)

The rotating device of claim 6, wherein the upper clamping disc engages with an inner periphery of the detecting disc for clamping the detecting disc in the clamping zone.

### Claim 8 (depends on 7)

The rotating device of claim 7, wherein the rotating disc supports a bottom side of the detecting disc when the detecting disc is clamped in the clamping zone.

### Claim 9 (depends on 8)

The rotating device of claim 8, wherein the other side of the left clamping disc and the other side of the right clamping disc near the clamping zone abut against two sides of the detecting disc and cooperatively clamp the detecting disc by a resilient force of the recovering component.

### Claim 10 (depends on 1)

The rotating device of claim 1, wherein a central angle of the clamping zone is equal to a central angle of the overlapping zone.
