The support frame 45 is respectively clamped on the turntable 22 and the dynamometer 32 through the clamping column 41. The transmission component 1 is arranged on the base frame 2 and cooperates with the first screw 3. The first screw 3 rotates to control the dynamometer 32 to approach or move away from the turntable 22. The rotating rod 43 is controlled to slide on the clamping block 421 according to the length of the cut cloth, so as to control the pressure plate 44 to slide above the support frame 45. When the pressure plate 44 moves to a suitable position, the cloth is placed on the pressure plate 44 frame for fixing. The dynamometer 32 is controlled to move away from the turntable 22 through the transmission component 1, so that the cloth is pulled and broken, the value of the dynamometer is observed, and the above action is repeated to compare the values ​​to obtain the average, so as to measure the accurate tension value. When the cut cloth becomes larger or smaller, the pressure plate 44 can be controlled to be located at the support frame 45 to increase the accuracy of the measured value.

[0030] As an embodiment further provided by the present invention, the pressing plate 44 has a groove 442, and a limiting plate 444 is slidably arranged in the groove 442. A spring 443 is arranged between the limiting plate 444 and the pressing plate 44, and the spring 443 pushes the limiting plate 444 to fit with the support frame 45.

[0034] As an embodiment further provided by the present invention, side panels 23 are symmetrically arranged on the base frame 2, and the side panels 23 are transparent plastic panels. Hand grip grooves are opened on the side panels 23 to facilitate the disassembly and assembly of the side panels 23. The side panels 23 are made of transparent material, which is convenient for observing the tension of the fabric during the tensile test and preventing the fabric from flying away and causing damage to people after the fabric breaks.

[0035] As a further embodiment of the present invention, the turntable 22 is provided with hand grip grooves in a circular array, and the hand grip grooves are arc-shaped and suitable for the hand, so as to facilitate manual turning of the price turntable 22 to adjust the clamping assembly 4 to a suitable angle.

[0036] Working principle: First, according to the length of the cut cloth, the control rod 43 is located on the slide groove of the clamping block 421 to slide, and the pressure blocks of the two clamping assemblies 4 are moved to the same position through the scale line 46. Due to the push of the spring 443, the limit plate 444 is always in contact with the support frame 45. When the cloth is placed under the pressure plate 44, the rotation rod 43 is rotated after contacting the limit plate 444 to control the pressure plate 44 to approach the support frame 45 and fix the cloth. The motor 11 drives the second gear 16 to engage the first gear 15 to rotate, and the first screw 3 rotates synchronously to control the dynamometer 32 on the slider 31 to move away from the turntable 22.
