[0002] TPU flocking material is an artificial fabric made of polyurethane (TPU) with a flocked surface. TPU is a thermoplastic elastomer with high strength, high wear resistance, oil resistance and chemical resistance. Flocking is a fiber physical processing technology that fixes slender fiber materials (usually polyester fibers) on another substrate (such as fabric) by mechanical methods to form a dense fluff surface. After the TPU flocking material is finished, tensile testing is one of the common quality control methods. The tensile test can evaluate the strength and ductility of the material when subjected to tension to determine its ability to adapt to specific applications.

[0003] However, the existing TPU flocking material tensile strength testing device has problems in clamping and fixing the composite fabric, which makes the composite fabric easy to fall off. At the same time, data recording is also difficult, and it is difficult to quickly record the data during the testing process. Utility Model Content

[0009] Furthermore, a non-slip pad is provided at the bottom of the upper square clamp block, and a non-slip pad is provided at the top of the lower square clamp block.

[0010] Furthermore, two second convex blocks are provided at the bottom of the H-shaped movable frame, the second convex blocks are located in the transverse convex grooves, and the second convex blocks are adapted to the transverse convex grooves.

The outer surface of the threaded rod 51 is provided with a spring 54 between the transverse connecting column 3 and the circular stop pin 52. The threaded rod 51 is threadedly connected to the transverse connecting column 3. The threaded rod 51 is rotated by hand cranking the hand crank 53 to drive the circular stop pin 52 to rotate, and the inner ring of the bearing 9 also rotates. Since the threaded rod 51 is threadedly connected to the transverse connecting column 3, the bearing 9 can move linearly, and then the H-shaped moving frame 4 can move linearly. Manual adjustment can more accurately control the distance between the clamp blocks, thereby achieving the required force control effect;
