[0022] In this embodiment, the connection assembly 2 includes a mounting seat 201 fixed on the top surface of the base plate 1, and a connecting ring 1 202 is fixed on the mounting seat 201. The detection assembly 3 includes a tension sensor 301 fixed to the middle of the bottom surface of the clamp seat 4, and a connecting ring 2 302 is fixed to the bottom of the tension sensor 301; the power device 5 includes two vertically arranged cylinders 501, and the two cylinders 501 are respectively located on both sides of the clamp seat 4, and the fixed ends of the cylinders 501 are fixed on the base plate 1. The actuating end is fixedly connected to the clamp seat 4; the height adjustment mechanism 7 is used to adjust the height of the mounting plate 8, so that the distance between the rod body 10 and the clamp seat 4 can be adjusted; the buffer assembly 9 includes a vertically arranged damper 91, the upper end of the damper 91 is fixedly connected to the mounting plate 8, and the lower end of the damper 91 is fixed to the top surface of the rod body 10; the outer periphery of the damper 91 is provided with a spring 92, and the two ends of the spring are respectively against the clamp seat 4 and the rod body 10.

[0023] The working principle of the above technical solution is: fix the two ends of the cable to be tested on the connecting ring 1 202 and the connecting ring 2 302 respectively; adjust the height of the mounting plate 8 through the height adjustment mechanism 7 according to the cable specifications, theoretical value of tensile strength and theoretical elongation value and other parameters, so that the distance between the rod body 10 and the clamp seat 4 is maintained at an appropriate distance; then, control the two cylinders 501 to apply an upward force to the clamp seat 4 at the same time, drive the clamp seat 4 and the detection component 3 to move upward synchronously, and the cable can be stretched.

[0024] With this solution, when the cable cannot withstand the tension and suddenly breaks, the power device 5 drives the clamp seat 4 to continue to move upward and squeezes the bottom surface of the rod body 10. Under the action of the buffer component 9, a certain damping force can be provided to resolve the inertial impact force generated by the clamp seat 4, thereby protecting the power device 5 and improving safety in use.

[0025] In a further optimized solution, the bottom of the rod body 10 slides through the mounting frame 6 and is fixed with a plate body 11, and a buffer pad is fixed to the bottom surface of the plate body 11. When the clamp seat 4 continues to move upward, the buffer pad will be squeezed first. By setting the plate body 11 and the buffer pad, the buffer effect of the clamp seat 4 can be further improved.

[0026] A further optimized solution is that buffer components 12 are correspondingly arranged on both sides of buffer component 1 9, one end of buffer component 12 is connected to the mounting plate 8, and the other end is connected to a slider 13, and the slider 13 is slidably connected to the mounting plate 8; a rod body 2 14 is hinged on the slider 13, and the end of the rod body 2 14 is hinged to the rod body 10.

[0028] With this solution, when rod body 10 moves upward, under the action of rod body 2 14, the two sliders 13 are driven to move linearly in directions away from each other, and the two sliders 13 respectively squeeze buffer component 2 12; under the action of buffer component 2 12, the buffering effect on the clamp seat 4 can be further improved.

The output shaft of the rotating drive component 72 is dynamically connected to the upper end of one of the driving threaded rods 71. Under the action of the transmission assembly 73, it can achieve the effect of driving the two threaded rods 71 ​​to rotate synchronously, thereby driving the mounting plate 8 to move up and down in the vertical direction, thereby achieving the effect of adjusting the height of the mounting plate 8.
