The top pin cap 701 is fixed on the reaction cup tray 5, the top pin 702 is arranged in the top pin cap 701, and the spring 703 is sleeved on the top pin 702. The top end of the top pin 702 is exposed out of the top pin cap 701 at the normal state, and the height is equal to the distance from the bottom end of the top pin 702 to the back surface of the reaction cup tray 5. The mechanical unlocking mechanism 7 is arranged, so that the reaction cup tray 5 can be pulled out after the chemiluminescence detector is integrally debugged or the electromagnetic lock 13 is manually unlocked under the fault condition.
As shown in fig. 1 and 4, the rear end of the bottom plate 1 is also provided with an optical coupler sensor 3, the bottom of the reaction cup tray 5 is provided with an optical coupler blocking piece, the optical coupler sensor 3 is used for detecting whether the reaction cup tray 5 is pushed in place, the sensing signal is sent to a controller of a chemiluminescence detector, and whether the reaction cup holder is located at the correct position or not is judged conveniently, so that whether the mechanical clamping jaw can clamp the reaction cup from the plate or not is determined. After the reaction cup in one reaction cup holder is used up, the electromagnetic lock works automatically, and the drawer pops up automatically under the action of the repulsive force of the magnet to prompt a doctor to load a new reaction cup holder. At the moment, the clamping jaw can clamp the reaction cup from the reaction cup holder in the drawer which is not opened by the electromagnetic lock for testing, so that online loading is realized. And when a certain reaction cup holder is working, the electromagnetic lock can not be opened, thereby preventing the doctor from mistakenly opening the loading drawer through the drawer handle to cause the abnormal working of the machine.
