[0024] By means of the adjustment component 6 arranged at the rear side of the operation box 1 and the closable operation box 1, the heating and humidification inside the operation box 1 can be controlled when the protective clothing fabric is tested, thereby simulating different use environments and testing the tensile properties of the protective clothing fabric, thereby improving the applicability of the device. At the same time, by providing a fixing component 5, the protective clothing fabric can be clamped and fixed between the tensile tester 4 and the stretching component 3 by controlling the fixing component 5, and the protective clothing fabric is stretched by driving the fixing component 5 through the stretching component 3, thereby facilitating the fixing of the fabric, and the operation is simple and the fixation is firm, thereby improving the test accuracy.

[0025] like Figure 2 and Figure 3As shown, the adjustment component 6 includes an installation chamber 61, a water tank 63 and a water pump 64. The installation chamber 61 and the water tank 63 are both fixedly installed on the rear side of the operating box 1.

The water pump 64 is connected to the water tank 63. The other end of the water pump 64 is fixedly connected to an atomizing nozzle 65. The atomizing nozzle 65 is fixedly installed on the top of the operating box 1. A temperature and humidity sensor 66 is fixedly installed on the right side inside the operating box 1.

[0026] The electric heating wire 62 in the control installation room 61 is used to heat the environment in the operation box 1 to increase the temperature. The clean water in the water tank 63 is pumped by the water pump 64 and slowly sprayed into the operation box 1 through the atomizing nozzle 65. The temperature and humidity of the environment in the operation box 1 are monitored by the temperature and humidity sensor 66 to stop heating and spraying, thereby controlling the temperature and humidity in the operation box 1 to simulate the tensile properties of the protective clothing fabric under different usage environments and improve the applicability of the device.

[0027] like Figure 5 As shown, the fixing assembly 5 includes a shell 51, two connecting shafts 52 are fixedly installed inside the shell 51, and support plates 53 are rotatably installed outside the two connecting shafts 52.

[0028] The protective clothing fabric is arranged between the clamping parts 55 and the two-way cylinder 54 is controlled to extend outward to push the support plate 53 to rotate and move outward along the connecting shaft 52, so that the clamping part 55 rotates inward and the fabric is clamped and fixed by the rubber tooth pad 56, thereby facilitating the clamping of the protective clothing fabric and improving stability.
