[0003] The existing rapid screening kits for chlorinated hydrocarbons at ports are simple and efficient to use. The staff first prepares the kit, then prepares the sample to be tested, and performs pretreatment according to the instructions, such as collection, dilution or extraction. Next, an appropriate amount of the sample is added to the kit, and a designated agitator or mixing device is used to thoroughly mix the sample and reagent, and then the reagent and sample are allowed to react chemically. After the specified reaction time, the staff observes whether color changes, fluorescence changes or other visual reaction indications occur in the kit.

[0025] Specifically, when using the rapid screening kit for chlorinated hydrocarbons at the port, first place the sample tube into the sample slot 6, and then turn the knob 2. The knob 2 drives the screw 3 to rotate, so that the connecting block 4 drives the soft foam glue 5 to fix the sample tube to prevent the sample tube from shaking during the test, which affects the reliability and repeatability of the test results. The soft foam glue 5 has softness and elasticity, can provide a good buffering effect, and can protect the sample tube from damage by external forces. After the sample tube is fixed, the heating block 9 is started to heat the sample tube according to the required temperature, and then the test work can be carried out.

[0026] Reference Figure 1 - Figure 3 The rotating assembly includes a knob 10 and a screw 11, one side of the outer wall of the knob 10 is fixedly connected to one end of the screw 11, one side of the outer wall of the knob 10 is rotatably connected to one side of the outer wall of the box body 1, and the outer wall of the screw 11 is rotatably connected to the inside of the box body 1;

[0027] Specifically, when using the rapid screening kit for chlorinated hydrocarbons at the port, when a sample tube with a larger diameter needs to be placed, first turn the knob 10, which can drive the screw 11 to rotate, and then through the cooperation of the slider 12, the overall width of the box body 1 can be lengthened. In the device, there are eight box bodies 1, and the eight box bodies 1 form an overall test kit. There are eight bases 8 to increase the stability of the overall test kit.

[0028] Reference Figure 2 - Figure 4 The outer wall of the box body 1 is threadedly connected with a slider 12, and the outer walls of the sliders 12 are fixedly connected to the inside of the box body 1. The box body 1 is slidably connected with a slider 13, and a slide groove 3 21 is opened inside the box body 1. The outer wall of the slider 13 is slidably connected inside the slide groove 3 21. One side of the outer wall of the box body 1 is rotatably connected with a knob 3 18, and one side of the outer wall of the knob 3 18 is fixedly connected with a variable pitch screw 14. The outer wall of the variable pitch screw 14 is threadedly connected with a slide cylinder 15, and the outer wall of the slide cylinder 15 is fixedly connected to the inside of the box body 1. The outer wall of the variable pitch screw 14 is threadedly connected with a slide cylinder 2 16, and the outer wall of the slide cylinder 2 16 is fixedly connected to the inside of the box body 1. The outer wall of the variable pitch screw 14 is threadedly connected with a slide cylinder 3 17, and the outer wall of the slide cylinder 3 17 is fixedly connected to the inside of the box body 1. The box body 1 is slidably connected with a slider 2 19, and a slide groove 20 is opened inside the box body 1. The outer wall of the box body 1 is slidably connected inside the slide groove 20;

[0029] Specifically, when using the rapid screening kit for chlorinated hydrocarbons at the port, when a sample tube with a larger diameter needs to be placed, turn knob three 18, and then knob three 18 drives the variable pitch screw 14 to rotate, and then the variable pitch screw 14 drives slide cylinder one 15, slide cylinder two 16 and slide cylinder three 17 to move, thereby causing slide cylinder one 15, slide cylinder two 16 and slide cylinder three 17 to drive the corresponding box body 1 to move, so that the overall length of the box body 1 becomes longer. The reason for using the variable pitch screw 14 in this structure is that the pitch of the variable pitch screw 14 is not constant, and changes with the axial movement of the screw.

[0030] Working principle: When using the rapid screening kit for chlorinated hydrocarbons at the port, first place the sample tube into the sample slot 6, then turn knob 1 2, knob 1 2 drives screw 1 3 to rotate, and then the connecting block 4 is forced to drive the soft foam glue 5 to move to the left to fix the sample tube. When a sample tube with a larger diameter needs to be placed, first turn knob 2 10, and then knob 2 10 drives screw 2 11 to rotate. At this time, the slider 12 is forced to drive the box body 1 to move to the right, so that the overall width of the box body 1 becomes longer, and then turn knob 3 18, knob 3 18 drives the variable pitch screw 14 to rotate. At this time, the variable pitch screw 14 drives slide 1 15, slide 2 16 and slide 3 17 to move respectively, and slide 15, slide 2 16 and slide 3 17 respectively drive the corresponding box body 1 to move, so that the overall length of the box body 1 becomes longer, until the diameter of the sample slot 6 can accommodate the sample tube.
