The application discloses a PCR reaction device for home detection and relates to the technical field of
nucleic acid detection boxes. In order to solve the problem that
nucleic acid detection kits are prone to loosening and thus causing the detection materials to be damaged and spilled when the
nucleic acid detection kits are squeezed during storage and transportation, an inner box cavity is formed in the inner part of an outer box body, an inner box body is slidably arranged in the inner box cavity, a locking block groove is formed in the upper part of the inner box cavity, a locking block is slidably arranged in the locking block groove, the lower end of the locking block extends into the inner box cavity, the lower end surface of the locking block is matched with the inner box body, two iron blocks are symmetrically arranged in the inner part of the locking block, a
magnet block positioning end is arranged at one end of the outer box body, the outer box body is a box body with an open side, the inner box body is a box body with an open upper end,
magnet block grooves are symmetrically formed in one side of the
magnet block positioning end, and magnet blocks are movably arranged in the magnet block grooves.
