The plurality of fixing rods 73 are all movably connected to the protective plate 11. One end of the plurality of fixing rods 73 is fixedly connected to the outer side of the sleeve 10. The plurality of springs 74 are fixedly connected between the sleeve 10 and the protective plate 11. The plurality of springs 74 are respectively sleeved on the outer periphery of the fixing rods 73. The inner side of the bottom end of the protective plate 11 is fixedly connected with a clamping block 72 through a plurality of connecting rods 71. The clamping block 72 is set to an arc shape adapted to the card slot 6. The clamping block 72 is inserted into the corresponding card slot 6. The closing mechanism 9 includes a closing disk 91, a positioning groove 92 and a rotating shaft 93. One side of the upper end of the closing disk 91 is connected to the rotating shaft 93. 3 is rotatably connected to the bottom end of the corresponding protective plate 11, and two positioning grooves 92 are symmetrically provided on the upper end of the closing disk 91; the positioning mechanism 8 includes a fixed block 81, a pulling block 82, a tension spring 83 and a positioning rod 84, the fixed block 81 is fixedly connected to one side of the bottom end of the protective plate 11, the positioning rod 84 is movably sleeved with the fixed block 81, the top of the positioning rod 84 is fixedly connected with the pulling block 82, the tension spring 83 is fixedly connected between the pulling block 82 and the fixed block 81, the tension spring 83 is sleeved on the periphery of the positioning rod 84, and the bottom end of the positioning rod 84 corresponds to the positioning groove 92; the bottom end of the positioning rod 84 is provided with a ball head 12, the bottom end of the ball head 12 is movably inserted in the positioning groove 92, and the bottom end of the ball head 12 is adapted to the positioning groove 92.
[0019] Specifically, when the utility model is used, the two pull rings 13 are pulled according to the specifications of the actual container, and the pull rings 13 drive the protective plate 11 to move horizontally.

The ball head 12 is inserted into the positioning groove 92 through the restoring force of the tension spring 83, thereby limiting the position of the closing disk 91. The detection probe 4 is protected by the closing disk 91 and the two protective plates 11 to prevent the detection probe 4 from being directly exposed to the outside and being contaminated and damaged, thereby ensuring the detection performance of the detection probe 4.
