The light mirror area is used for placing the beam splitter and the mirror. 2.The smartphone-based portable detection device of claim 1, wherein, The sample area is used for placing the cuvette, which comprises a first cuvette and a second cuvette. An incident hole is arranged on the side wall of the detection box in the light mirror area. 3.The smartphone-based portable detection device of claim 2, wherein, The laser pointer fixing cylinder is used for fixing the laser pointer on the side wall of the detection box. The laser emitted by the laser pointer irradiates on the beam splitter through the incident hole. The beam splitter is used for splitting the laser into two beams with the same power and parallel to each other. One of the two beams of laser irradiates on the first cuvette through the first light transmission hole. 4.The smartphone-based portable detection device of claim 3, wherein, The other beam of laser irradiates on the mirror and then irradiates on the second cuvette through the second light transmission hole after being reflected by the mirror. The portable detection device further comprises a mobile phone camera shooting hole. 5.The smartphone-based portable detection device of claim 2, wherein, The mobile phone camera shooting hole is arranged on the cover or the side wall of the detection box. The smart phone takes a photo of the sample area through the mobile phone camera shooting hole. A support frame is arranged below the laser pointer fixing cylinder to support the laser pointer fixing cylinder. The bottom of the detection box is provided with two sample grooves, i.e. The first sample groove is used for fixing the first cuvette. The second sample groove is used for fixing the second cuvette. The cover comprises a flat cover and a conical cylinder cover. The flat cover is installed at one end of the top of the detection box to make the light mirror area a darkroom. The conical cylinder cover is installed at the other end of the top of the detection box to make the sample area a darkroom. A hollow cylinder is fixedly connected to the top of the conical cylinder cover. A smart phone fixing groove is arranged at the top of the hollow cylinder. The bottom of the detection box is provided with two positioning columns, i.e. The top of the positioning column is provided with a screw thread. The beam splitter is fixed by a beam splitter optical adjustment frame. The mirror is fixed by a mirror optical adjustment frame. The bottom of the beam splitter optical adjustment frame and the mirror optical adjustment frame is provided with an internal screw thread matched with the screw thread of the top of the positioning column. The beam splitter optical adjustment frame and the mirror optical adjustment frame are fixed on the first positioning column and the second positioning column respectively. The light mirror area is further provided with a light source mirror. The laser emitted by the laser pointer irradiates on the light source mirror through the incident hole. The light is reflected to the beam splitter by the light source mirror. The bottom of the detection box is fixed with three positioning columns, respectively, first positioning column, second positioning column and third positioning column, and the top of the positioning column is provided with a thread; the beam splitter is fixed through a beam splitter optical adjustment frame, the reflector is fixed through a reflector optical adjustment frame, and the light source reflector is fixed through a light source reflector frame; the bottom of the beam splitter optical adjustment frame, the reflector optical adjustment frame and the light source reflector frame is provided with an internal thread matched with the thread on the top of the positioning column; and the beam splitter optical adjustment frame, the reflector optical adjustment frame and the light source reflector frame are fixed on the first positioning column, the second positioning column and the third positioning column respectively. 6.The smartphone-based portable detection device of claim 5, wherein, The lid is provided with a mobile phone camera shooting hole corresponding to the middle position of the first cuvette and the second cuvette. 7.The smartphone-based portable detection device of claim 5, wherein, The middle position of the first cuvette and the second cuvette is provided with a mobile phone camera shooting hole on the side wall of the detection box; a mobile phone fixing groove for placing a smart phone is further arranged on the side wall of the detection box where the mobile phone camera shooting hole is located, the smart phone is placed in the mobile phone fixing groove, and the camera is aligned with the mobile phone camera shooting hole to take a photo of the sample area.
