The solution cylinder 31 is placed on the upper middle side of the workbench 1, and a partition is provided in the middle of the solution cylinder 31. Lifting frames 32 are placed on the upper left and right sides of the workbench 1, and the lower part of the lifting frames 32 is connected to the connecting seat 33, and the connecting seat 33 is rotatably connected to the connecting shaft 34.

When the cable protection tube passes through the lifting frame 32, the cable protection tube is placed on the placement block 35, and then water is added to one side of the partition of the solution cylinder 31, and then the lifting frame 32 is started, so that the pressing plate 39 presses the cable protection tube down to the side of the solution cylinder 31 without water, and the condition of the cable protection tube is observed, so as to test the bending resistance of the cable protection tube. While the pressing plate 39 is pressed down, it drives the first pull rope 310 to move, and the winding column 37 rotates, so that the first pull rope 310 pulls the lifting frame 32 to move upward, so that the placement block 35 moves upward to fold the cable protection tube in half, and the placement block 35 on the connecting shaft 34 is always in contact with the cable protection tube through the force of the first torsion spring 36.

[0036] The guide mechanism 4 of the device can be used to guide the cable protection tube. When the cable protection tube is placed in the protective cover 2, the guide rollers 46 are pushed to move away from each other, driving the first bearing sleeve 43 and the sliding frame 44 to move, and the first spring 47 and the second spring 48 are squeezed and contracted, and then the cable protection tube is placed between the guide rollers 46.
