[0029] Two rotating doors 37 are rotatably connected to the front of the box body 1 through hinges. The rotating doors 37 are used to facilitate the staff to put the fiber fabric body 2 into or take it out of the box body 1. A control panel 38 is fixedly connected to the front of the right rotating door 37. The control panel 38 is used for the operator to control the operation of the entire detection device, set various parameters and view the detection data.

[0030] In the present invention, the staff opens the revolving door 37 and places the fiber fabric body 2 into the box body 1. The staff places one end of the fiber fabric body 2 under the clamping plate 4, then holds the handle 6 and rotates it to drive the threaded rod 5 to rotate, so that the clamping plate 4 and the two T-shaped rods 7 move downward. The threaded rod 5 realizes vertical lifting adjustment through the threaded fit with the C-shaped plate 3. The T-shaped rod 7 slides along the C-shaped plate 3 to form a guiding structure to prevent the clamping plate 4 from shifting until the inner wall of the C-shaped plate 3 and the bottom of the clamping plate 4 clamp and fix one end of the fiber fabric body 2. The rubber material protective layer enhances the clamping stability by increasing the friction coefficient. Repeat this operation to clamp and fix the other end of the fiber fabric body 2 to complete the limiting operation of the fiber fabric body 2. Start the hydraulic rod 15 to drive the U-shaped plate 16 and the detection wheel 17 to move upward. The U-shaped plate 16 forms a stable support for the detection wheel 17 through the symmetrical structure. The rotational connection design of the detection wheel 17 enables it to roll freely when contacting the fiber fabric until the top of the detection wheel 17 contacts and abuts against the bottom of the fiber fabric body 2. The sensor 9 can measure the detection force received by the fiber fabric body 2. The sensor 9 is rigidly connected to the right C-shaped plate 3 through the connecting rod 8 to form a force transmission channel, and the detection force received by the fiber fabric body 2 is displayed through the control panel 38, facilitating people to know the elastic performance of the fiber fabric body 2. Start the first motor 11. The output end of the first motor 11 drives the first reciprocating screw rod 12 to rotate. The first reciprocating screw rod 12 realizes linear reciprocating transmission through the threaded fit with the slider 13. The sliding connection between the sliding rod 14 and the slider 13 restricts its movement trajectory, so that the slider 13, the hydraulic rod 15, the U-shaped plate 16 and the detection wheel 17 move reciprocally, thereby adjusting the position of the detection wheel 17 and detecting different positions of the fiber fabric body 2. By operating the control panel 38, the temperature of the controllable heating coil 25 can be controlled. Start the blower 23. The blower 23 can suck away the air in the filter net 22 to form a negative pressure, and the air in the box body 1 is injected into the collection box 21 through the multiple fixed heads 19, the hollow ring 18 and the air inlet pipe 20 on the left. The multiple fixed heads 19 are evenly arranged along the hollow ring 18 to ensure uniform air flow distribution. The filter net 22 can filter the dust in the air, and the purified air is injected into the heating box 24. The hot air in the heating box 24 is discharged through the air outlet pipe 26, the hollow ring 18 on the right and the multiple fixed heads 19 to control the temperature in the box body 1. The symmetrically arranged hollow rings 18 on the left and right form a circulating air duct to improve the temperature control efficiency, and the environmental temperature where the fiber fabric body 2 is located can be controlled, and the elastic performance of the fiber fabric body 2 under different temperature environments can be detected.Start the high-pressure water pump 29 and the second motor 33. Through the high-pressure water pump 29, the water in the water tank 27 can be injected into the hollow tube 31 through the water inlet pipe 28 and the water outlet pipe 30. The high-pressure water pump 29 realizes the precise control of the atomized water volume through pressure regulation. Finally, the water is sprayed out in the form of mist through a plurality of atomizing nozzles 32. The output end of the second motor 33 drives the second reciprocating lead screw 34 to rotate. The threaded engagement between the second reciprocating lead screw 34 and the moving plate 35 drives its axial movement. The limiting rod 36 restricts the moving plate 35 to slide only in a straight line direction, so that the moving plate 35, the hollow tube 31 and a plurality of atomizing nozzles 32 move reciprocally, and the mist can be evenly sprayed onto the fiber fabric body 2, so that the fiber fabric body 2 contains different amounts of water, the humidity of the fiber fabric body 2 can be controlled, and the elastic properties of the fiber fabric body 2 in environments with different humidities can be detected.

[0031] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
