[0030] When the utility model is implemented, Figure 1 and Figure 2 As shown, the bidirectional screw mechanism 2 includes a driving motor 201 and a bidirectional screw 202 at the output end of the driving motor 201. A rolling nut 203 is relatively installed on the outer side of the bidirectional screw 202 for use with it. Specifically, the bidirectional screw mechanism 2 is the existing technology. The driving motor 201 is installed in the mounting groove 7 by bolts. The bidirectional screw mechanism 2 also includes a limiting guide rod. The driving motor 201 drives the bidirectional screw 202 to work, so that the rolling nut 203 moves on the outer side of the bidirectional screw 202 and under the guidance of the limiting guide rod.

Specifically, the articulation can be achieved through the use of a shaft and a shaft hole, or through the coordinated use of an I-shaped block, a C-shaped block, a shaft, and a shaft hole. The first articulated arm 501, the second articulated arm 502, the third articulated arm 503, and the fourth articulated arm 504 form an articulated parallelogram. The bidirectional screw mechanism 2 drives the rolling nuts 203 toward or away from each other, thereby changing the parallelogram and causing the two sliders 3 to move toward or away from each other within the chute 6.

[0033] Example 1:

[0034] First, four clamping devices 4 are used to clamp the four sides of the flexible waterproof material respectively, and the flexible waterproof material is placed between the fixed clamp 401 and the movable clamp 402. The limiting groove 403 and the limiting protrusion 404 make the opposite surfaces of the fixed clamp 401 and the movable clamp 402 form a step structure. The fixing bolt 405 fixes the fixed clamp 401 and the movable clamp 402 through the threaded hole. At the same time, the reset spring 407 is compressed, and the driving motor 201 of the bidirectional screw mechanism 2 works, driving the bidirectional screw 202 to work, so that the rolling nut 203 moves on the outside of the bidirectional screw 202 and under the guidance of the limiting guide rod, so that the two rolling nuts 203 move away from each other, and at the same time, the two sliders 3 are driven closer to each other through the linkage device 5, so as to test the tensile strength of the flexible waterproof material in the lateral direction.

[0035] Example 2:

[0036] First, the four sides of the flexible waterproof material are clamped respectively by four clamping devices 4, and the flexible waterproof material is placed between the fixed clamp 401 and the movable clamp 402. The limiting groove 403 and the limiting protrusion 404 make the opposite surfaces of the fixed clamp 401 and the movable clamp 402 form a step structure. The fixing bolt 405 fixes the fixed clamp 401 and the movable clamp 402 through the threaded hole. At the same time, the reset spring 407 is compressed, and the driving motor 201 of the bidirectional screw mechanism 2 works, driving the bidirectional screw 202 to work, so that the rolling nut 203 moves on the outside of the bidirectional screw 202 and under the guidance of the limiting guide rod, so that the two rolling nuts 203 move away from each other. At the same time, the two sliders 3 are driven to approach each other through the linkage device 5, thereby testing the horizontal tensile strength of the flexible waterproof material. The driving motor 201 drives the bidirectional screw 202 to rotate in the opposite direction, drives the rolling nuts 203 to approach each other, and drives the two sliders 3 away from each other through the linkage device 5, thereby testing the vertical tensile strength of the flexible waterproof material.
