[0026] A bracket 10 is fixedly arranged at the upper end of the workbench 2. A plurality of third fixing frames 12 are symmetrically and fixedly arranged at the lower end of the bracket 10. Two groups of transmission wheels 17 are symmetrically and fixedly arranged at the upper end of the bracket 10. The third fixing frame 12 is fixedly arranged at the upper end of the workbench 2. The bracket 10 is used to support the fixing column 16. The third fixing frame 12 is used to fix the bracket 10. The transmission wheel 17 is driven to rotate by a first motor 13, so that the fixing column 16 can rotate.

[0027] A fixing column 16 is fixedly arranged between the two groups of transmission wheels 17. Two grooves 15 are symmetrically and fixedly arranged on the side wall of the fixing column 16. A plurality of electric push rods 27 are fixedly arranged inside one side of the fixing column 16. A soft suction pad 28 is fixedly connected to one side of the electric push rod 27. The transmission wheel 17 is rotatably connected to the surface of the groove 15. The fixing column 16 uses the electric push rod 27 to push the soft suction pad 28 to fix the cable inside it. The groove 15 is used for the transmission wheel 17 to rotate inside it. The electric push rod 27 converts the rotational motion into a linear motion to drive the soft suction pad 28 to work.

[0028] A first connecting rod 19 is fixedly arranged on one side of the transmission wheel 17. Two third fixing seats 18 are symmetrically and fixedly connected to the side wall of the first connecting rod 19. A first rotating shaft 14 is arranged on one side of the first connecting rod 19. A first motor 13 is fixedly connected to one side of the first rotating shaft 14. The first connecting rod 19 is used to connect the transmission wheel 17 and the third fixing seat 18 together. The first motor 13 drives the first rotating shaft 14 to rotate by the action of magnetic field force, so that the transmission wheel 17 can rotate.

At the lower end of the second fixing frame 5, a moving block 21 is fixedly connected. The moving block 21 is threadedly connected to the outer wall of the lead screw 9. The second fixing frame 5 drives the second fixing base 11 to slide through the work of the lead screw 9.

[0033] Working principle: First, the third motor 23 drives the threaded rod 6 to rotate, so that the fixing block 4 slides on the surface of the second sliding groove 26 to clamp the cable. An anti-slip pad 7 is fixedly connected inside the fixing block 4, so that the cable is clamped tighter and the anti-slip effect is better during the cable tensile test. The first motor 13 drives the first rotating shaft 14 to rotate, so that the transmission wheel 17 transmits power. The transmission wheel 17 is rotatably connected inside the groove 15. The groove 15 is fixedly connected to the side wall of the fixing column 16. Inside one side of the fixing column 16, a plurality of electric push rods 27 are fixedly arranged. On one side of the electric push rod 27, a soft suction pad 28 is fixedly connected, so that the tensile test of the cable under rotation is close to the real situation and the accuracy of the test result is ensured. By driving the lead screw 9 to work through the second motor 20, the moving block 21 on the side wall of the lead screw 9 drives the second fixing frame 5 to move, so that the device can perform a tensile test on the cable.
