The multi-section electric telescopic rod 2 moves along the height direction of the support plate 13. However, the existing low temperature environment adaptability test device suitable for SBS waterproofing membrane needs to immerse the hand in the frozen liquid when placing and taking the SBS waterproofing membrane during use. The test needs to reach minus several tens of degrees, which is easy to cause frostbite of the hand.

[0025] The improvement of the embodiment is that:

[0026] First, the multi-section electric telescopic rod 2 telescopes to drive the curling device to move up and down, then the handle 291 is twisted to drive the rotating rod 29 to rotate, then the rotating rod 29 drives the bevel gear 28 to rotate, and the bevel gear 28 drives another bevel gear 28 to rotate, and the other bevel gear 28 drives the bidirectional screw rod 24 to rotate, and the double-section electric telescopic rod 21 is retracted to drive the cylindrical rod 25 to move up, and the bidirectional screw rod 24 drives the clamping rod 26 to move forward and backward, so as to curl and release the SBS waterproof roll, and the SBS waterproof roll does not need to be immersed in the refrigerant when being placed and taken, and only a small amount of refrigerant needs to be added in the box 14, the SBS waterproof roll is fully immersed in the refrigerant by the extension of the multi-section electric telescopic rod 2, which saves the refrigerant, and multiple SBS waterproof rolls can be placed on the cylindrical rod 25 and tested at the same time.

[0027] In order to bend the SBS waterproof roll, the side plate 23 is fixedly connected to the bottom of the fixed plate 22, the bidirectional screw rod 24 is rotatably connected inside the side plate 23, the clamping rod 26 is threadedly connected to the outer surface of the bidirectional screw rod 24, the sliding rod 27 is slidably connected inside the clamping rod 26, and the sliding rod 27 is fixedly connected to the inside of the other side plate 23. First, the bidirectional screw rod 24 drives the clamping rod 26 to move, and then the clamping rod 26 drives the SBS waterproof roll to bend, so as to facilitate bending of the SBS waterproof roll.

[0028] In order for the hand to rotate the bidirectional screw rod 24 without being inside the refrigerant, the bevel gear 28 is fixedly connected to the end of the bidirectional screw rod 24, another bevel gear 28 is meshingly connected to the outer surface of the bevel gear 28, the rotating rod 29 is fixedly connected to the end of the other bevel gear 28, the twisting handle 291 is fixedly connected to the other end of the rotating rod 29, the L-shaped plate 241 is rotatably connected to the outer surface of the bidirectional screw rod 24, the L-shaped plate 241 is rotatably connected inside the bidirectional screw rod 24, the twisting handle 291 is first rotated to drive the rotating rod 29 to rotate, then the rotating rod 29 drives the bevel gear 28 to rotate, then the bevel gear 28 drives the other bevel gear 28 to rotate, and the other bevel gear 28 drives the bidirectional screw rod 24 to rotate, so that the hand can rotate the bidirectional screw rod 24 without being inside the refrigerant.

[0029] Secondly, in order for the SBS waterproof roll not to be taken out one by one to check whether there is a crack, the T-shaped slot 111 is formed in the outer surface of the cover 11, and the magnifying glass 12 is fixedly connected to the inner surface of the back surface near the T-shaped slot 111. First, the magnifying glass 12 can see whether there is a crack in a row of SBS waterproof rolls, and it is convenient to record, so that the SBS waterproof roll does not need to be taken out one by one to check whether there is a crack.
