[0025] In summary, a specific application of the above two embodiments is as follows: First, two identical composite materials are respectively placed inside the detection chamber A3 and the detection chamber B4 and are located between the two carrying frames 14. Subsequently, the hydraulic rod 31 is started to pull the eccentric plate 29. Since the eccentric plate 29 is supported by the rotating shaft 28, the hollow shaft rod 25 can be driven to rotate through the rotating shaft 28, and with the connection between the two transmission bevel gears 26, the power of the rotating shaft 28 can be transmitted, prompting the transmission shaft rod 20 to drive the guiding shaft rod 21 to rotate. Under the connection between the guiding shaft rod 21 and the transmission plate 22, while the transmission plate 22 follows the guiding shaft rod 21 to rotate, it can also drive the two linkage plates 18 to approach each other by means of the displacement of the transmission column 23 inside the linkage through groove 19 until the composite material is positioned between the two positioning clamping plates 16; The sealing door 5 is closed, and the humidifier 33 is started. The water mist generated during the operation of the humidifier 33 will be introduced into the spray pipe 32 through the inlet pipe A34 to be introduced into the detection chamber B4 through the spray pipe 32, and the temperature and humidity changes inside the detection chamber B4 are detected in real time by the temperature and humidity sensor 8. When the humidity inside the detection chamber B4 is appropriate, the control panel controls the humidifier 33 to stop running; When the temperature inside the detection chamber B4 is relatively low, the electric heating wire 38 is first started, and the drainage fan 37 is started to introduce the air flow into the diversion cylinder 35. When the air flow passes through the cooling cylinder 39, the air flow can be heated by means of the electric heating wire 38. The heated air flow will be injected into the spray pipe 32 through the inlet pipe B42 and finally sent into the detection chamber B4 through the spray pipe 32 to promote the temperature rise inside the detection chamber B4; Liquid is added to the cooling cylinder 39 in advance. When the temperature inside the detection chamber B4 is high, the semiconductor refrigeration chip 41 is activated. The low temperature generated by the semiconductor refrigeration chip 41 will cool the liquid in the cooling cylinder 39. At the same time, the drainage fan 37 is activated. The airflow transmitted by the drainage fan 37 passes through the cooling cylinder 39, which can remove the heat from the low-temperature liquid. Finally, the low-temperature gas is injected into the detection chamber B4 through the nozzle 32. When the nozzle 32 is in operation, the drive motor 47 is activated to rotate the drive spur gear 48, causing the drive spur gear 48 to shift the reduction spur gear 50. This, in turn, drives the eccentric conductive plate 51 to continuously rotate via the drive shaft 49. The eccentric conductive plate 51 is connected to the adjustment slot 46. When the eccentric conductive plate 51 rotates, it drives the adjustment plate 45 to swing back and forth following the rotation of the eccentric conductive plate 51. Because the adjustment plate 45 is supported by the adjustment shaft 44 and connected to the nozzle 32, the nozzle 32 can adjust its operating direction following the swing of the adjustment plate 45, thereby reducing the operating blind spot of the nozzle 32. When cooling the detection chamber B4, the electric push rod 59 can be activated to pull the sealing cover plate 56 away from the temperature control cylinder 52 until the acceleration spur gear 58 is connected to the reduction spur gear 50, thereby releasing the blockage of the temperature control cylinder 52. When the subsequent driving spur gear 48 drives the reduction spur gear 50 to rotate, the reduction spur gear 50 can be used to shift the driving spur gear 48, prompting the acceleration spur gear 58 to drive the guide plate 55 to rotate, so as to extract the gas in the detection chamber B4, so that the inside of the detection chamber B4 can be cooled quickly. When the temperature and humidity inside the detection chamber B4 reach the appropriate level, the transmission motor 12 is started to drive the central shaft 10 to rotate. In conjunction with the arrangement of the two threaded sections 11 on the central shaft 10 with opposite screw threads, the two displacement seats 13 can be driven to move away from each other. Since the composite material is located between the two displacement seats 13, tension can be applied to the composite material through the displacement of the displacement seats 13 until obvious damage occurs to the composite material. By measuring the distance between the two displacement seats 13, the tensile strength limit of the composite material can be obtained. Moreover, since the environments inside the detection chambers A3 and B4 are different, personnel can conduct comparative observations, making the tensile strength test of the composite material under different environments more intuitive. The adjusting screw 60 can be rotated. Under the connection between the adjusting screw 60 and the cross plate 24, the adjusting screw 60 can drive the guide shaft 21 to move linearly with the help of the pushing plate 61. When the transmission column 23 is disengaged from the linkage groove 19, the linkage plate 18 can be unlocked, and then the extension frame 17 can be slid out from the carrying shaft 15, and the positioning splint 16 can be adaptively replaced according to the type of composite material.
