[0033] like Figure 1 , Figure 4 and Figure 5 When the second clamping block 10 moves up and down, one end of the second clamping block 10 slides inside the sliding groove 15, controlling the position of the second clamping block 10. When the position of the first clamping block 9 is moved, the lower end of the limiting block 16 slides inside the limiting groove 17, controlling the position of the first clamping block 9.

[0038] The working principle of the airbag fabric tensile testing device provided by this utility model is as follows:

[0039] Slide the limiting block 16 into the limiting groove 17, slide a first clamping block 9 onto the upper part of the operating table 1, thread the third bolt 21 into the extension plate 20 and the operating table 1, thread the fourth bolt 23 into the connecting plate 22 and the operating table 1, place both ends of the airbag fabric body 11 between the two first clamping blocks 9 and the two second clamping blocks 10 respectively, slide the second clamping block 10 onto the upper surface of the first clamping block 9 so that the protrusion 12 is slidably positioned inside the groove 13, and thread the first bolt 14 into the first clamping block 9 and the second clamping block 10.

[0041] Beneficial effects:

[0042] This utility model, due to the fact that the drive component includes a control block 2 and a motor 3, etc., clamps and fixes the position of the airbag fabric body 11 by two first clamping blocks 9 and two second clamping blocks 10. Through the cooperation of the first transmission gear 4 and the second transmission gear 5, the rotating block 6 rotates at one end of the control block 2, causing the threaded rod 7 to move inside the rotating block 6, pulling one of the first clamping blocks 9 to move on the upper surface of the operating table 1. The tensile length of the airbag fabric body 11 is measured by the scale 18, which improves the testing efficiency of the tensile performance of the airbag fabric body 11.

[0043] Since the mounting components include extension plate 20 and third bolt 21, the position of control block 2 is fixed by the cooperation of third bolt 21 and extension plate 20, and the position of another first clamping block 9 is fixed by the cooperation of fourth bolt 23 and connecting plate 22, which facilitates the installation and disassembly of airbag fabric tensile testing device as needed.
