Background
In the process of collecting suspended particulates PM5 and PM2.5 samples in the atmosphere by using a MH1210 type multistage particle sampler sampling head TSP collector, firstly, an annular filter membrane is required to be placed in an annular groove of the TSP collector for sampling, and the requirements for placing the filter membrane are as follows: the annular filter membrane is flatly attached to the bottom plane of the annular groove, and the inner annular edge and the outer annular edge of the annular filter membrane are tightly attached to the inner annular edge and the outer annular edge of the annular groove of the TSP collector. After the sampling is finished, the annular filter membrane placed in the annular groove of the TSP collector needs to be completely taken out for weighing, and the following problems exist in the process: because a right angle exists between the bottom plane of the annular groove of the TSP collector and the annular edges with the two edges turned upwards, the height of the annular edges is about 14.0-14.5 mm, and the annular filter membrane placed in the annular groove is tightly attached to the bottom and the edges of the deeper annular groove after being impacted by air flow in the sampling process, and the annular filter membrane is difficult to be completely and flatly taken out in the filter membrane taking-out process. The common practice is to use a longer large needle to prick the filter membrane and use the filter membrane together with forceps to move and take out the filter membrane, and serious deformation and even rupture of the annular filter membrane often occur in the process. In the serious deformation or rupture process of the filter membrane, partial particles adsorbed on the filter membrane can fall off, so that errors are generated in sampling data, the accuracy of the sampling data is directly affected, and hidden dangers of inconvenient membrane taking and inaccurate sampling data exist.

5. The design that the forceps ears are folded up by 45-80 degrees at the root connected with the annular filter membrane supporting plate, when the forceps ears are folded up by 90 degrees, the forceps ears are enabled to obtain outward elastic force due to the elasticity of the rubber sheet, the elastic force enables the forceps ears to be tightly attached to the side annular edges after the annular filter membrane is placed into the annular groove of the TSP collector, and the influence on the accuracy of sampling data caused by inward folding of the forceps ears due to air flow impact in the suspension particle cutting and sampling process is avoided.
