Currently, the main POCT nucleic acid detection technology in the market is the qPCR nucleic acid detection technology. The qPCR nucleic acid detection technology has strong specificity and high sensitivity, can quantitatively detect pathogens, and can well achieve high-throughput detection. In the detection, a thermal cycler is required for the thermal cycling process. However, the thermal cycler is large in volume, high in price, and relatively long in detection time, which greatly limits its popularization at the grass-roots level and on-site detection. The constant temperature nucleic acid amplification detection technology has stood out in the timely on-site detection market due to its advantages such as fast detection and low price.

Therefore, in view of the above problems, the utility model provides a program writing positioning tooling for a constant temperature nucleic acid amplifier. Summary of the Utility Model
