[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. The schematic embodiments and descriptions of the present invention are used to explain the present invention but are not intended to limit the present invention.

[0020] like Figure 1-3As shown: the utility model includes a frame 1, a sliding assembly, a clamping assembly and an indicating assembly. There are two sliding assemblies, and the lower ends of the two sliding assemblies are each provided with the clamping assembly. The two groups of the clamping assemblies are respectively clamped at the two ends of the cable to be tested 9, and the indicating assembly is provided on the sliding assembly.

[0021] Furthermore, the sliding assembly includes a sliding rod 2 and a sliding seat 3. There are two sliding rods 2, and the two sliding rods 2 are respectively fixed between the upper ends of the two frames 1. The sliding seat 3 is provided with two through holes. The sliding rod 2 passes through the through holes of the sliding seat 3 and can slide. The lower end of the sliding seat 3 is connected to the clamping assembly, and the indicating assembly is provided on the front side of the sliding seat 3.

[0022] Specifically, the clamping assembly includes a clamping seat 5, a clip 6, a clamping screw 7, and an end bearing 8. The clamping seat 5 is fixedly connected to the lower end of the sliding seat 3. The clamping screw 7 passes through one side of the clamping seat 5, and the clamping screw 7 and the clamping seat 5 are threadedly connected. The end of the clamping screw 7 is rotatably connected to the clip 6 through the end bearing 8. The clip 6 is close to the inner wall of the clamping seat 5, and the end of the cable 9 to be tested is clamped between the clip 6 and the inner wall of the clamping seat 5.

[0023] Specifically, the indicating assembly includes a ruler 4, a pointer 10, a pendant 11, and a hanging rope 12. The ruler 4 is fixed on the frame 1, the ruler 4 is located on the front side of the sliding seat 3, one end of the pointer 10 is fixedly connected to the sliding seat 3, the indicating end of the pointer 10 is located on the front side of the ruler 4, the upper end of the hanging rope 12 is fixedly connected to the outer side of the clamping seat 5, and the lower end of the hanging rope 12 is fixedly connected to the pendant 11.

[0024] The working principle of this utility model is as follows:

[0025] When the cable 9 to be tested needs to be tested, the two ends of the cable 9 to be tested are clamped by tightening the clamping screw 7 and compressing the clamping piece 6, and fixed to the lower ends of the two sliding seats 3. By adjusting the spacing between the two sliding seats 3, the cable 9 to be tested naturally droops, and the middle section is in an arc shape. At this time, the pendant 11 droops, and the side of the cable 9 to be tested shows an inclination with the hanging rope 12. The greater the deflection of the cable 9 to be tested, the farther the middle section of the cable 9 to be tested is from the hanging rope 12. During the test, the deflection of the cable 9 to be tested can be judged by the width indicated by the pointer 10 and the distance between the reference hanging rope 12 and the cable 9 to be tested, which makes the test convenient.
