[0028] An annular stepped anti-overflow groove 2 is provided on the inner wall of the reaction well 1. The anti-overflow groove 2 includes at least two interception platforms distributed from the inside to the outside. When the sample volume exceeds the designed capacity, the excess liquid is intercepted by the first and second platforms in turn, solving the problem of cross contamination between adjacent wells.

[0029] The protrusion 7 is formed integrally with the hole body of the reaction hole 1 by a stamping process. A plurality of protrusions 7 are evenly distributed along the circumference of the bottom of the reaction hole 1.
