Claim 0:
1. A photon measuring and reading device, comprising a mounting seat and a photon counter with a data acquiring port facing downward, and the photon counter is capable of moving up and down on the mounting seat, wherein
the mounting seat is provided with a sliding trough running through the mounting seat and arranged vertically, and the photon counter is fixed with a sliding rod passing through the sliding trough and slidably connected with the sliding trough;
the mounting seat is provided with a double head motor having output shafts at a head end and at a tail end and arranged laterally side by side with the photon counter, the output shaft at the tail end of the double head motor extends through and out of the mounting seat, and a linkage mechanism for driving the sliding rod to move up and down is arranged between the output shaft at the tail end of the double head motor and the sliding rod;
a hollow box body is fixed at a bottom end of the photon counter, the data acquiring port of the photon counter is communicated with an interior of the box body, a side wall of the box body away from the photon counter is provided with a light inlet opposite to the data acquiring port of the photon counter, a light-blocking block capable of covering the light inlet is arranged in the box body, a push rod extending through the side wall of the box body is arranged at one end of the light-blocking block facing the double head motor, the push rod is slidably connected with the side wall of the box body, one end of the push rod is fixedly connected with the light-blocking block, and the other end of the push rod is located outside the box body, acting as a free end of the push rod; and
a driving level is arranged on the output shaft at the head end of the double head motor, and is capable of pushing the push rod so that the light-blocking block is moved off the light inlet when the photon counter is moved to a lowest position; and the box body is provided with an elastic resetting member configured to push the push rod to move towards the outside of the box body, so that the light-blocking block is positioned opposite to the light inlet.
