[0025] The working principle of the utility model is as follows: when in use, the two-way screw rod 4 can be rotated by twisting the handle to synchronously adjust the two clamping plates 5 to move relatively inward or outward, so as to clamp and fix the cable between the two clamping plates 5. Then, according to the size of the cable diameter to be detected, the plug rod 24 is moved out of the insertion hole by pulling the pull handle 25, and the pull handle 25 will stretch the spring three 26, and then the pull handle is pulled to drive the connected guide rod 21, so that the guide rod 21 drives the slider 20 connected thereto to move synchronously and squeeze the spring two 22, and at the same time the slider 20 will drive the connected rack 19 to drive the gear 18 to rotate, so that the gear 18 drives the rack 19 meshing with it on the other side to drive the other slider 20 to move, so that the two sliders 20 can move in the relative outer direction, and at the same time the slider 20 will drive the limit plate 17 connected at the bottom to move synchronously, and then the distance between the two limit plates 17 can be understood according to the scale value on the scale 28 aligned with the indicator mark 27 driven by the limit plate 17, so that after moving to the appropriate distance, the pull can be released. The force applied by the handle 25 causes the handle 25 to drive the insertion rod 24 to reset under the elastic force of the spring three 26, so that one end of the insertion rod 24 is inserted into the corresponding insertion hole, thereby realizing the limit fixation of the guide rod 21, thereby completing the limit fixation of the limit plate 17. When it is necessary to reduce the distance between the two limit plates 17, the handle on one side can be directly pushed to push the connected guide rod 21 to move, and at the same time, the inclined surface in the insertion hole on the guide rod 21 can be used to squeeze and push one end of the insertion rod 24 to move it out of the insertion hole. After the movable socket 24 is misaligned with the insertion rod 24, the insertion rod 24 will reset and move under the elastic force of the spring three 26 and be inserted into the corresponding socket, and so on and so forth, the guide rod 21 can be pushed to move, so that the two limit plates 17 can be moved inwardly relative to each other, thereby reducing the distance between the two limit plates 17, so that it can be used as a limit guide for cables of different diameters, so that when the cable is subjected to a bending test, the cable can be limited and blocked to prevent its displacement and sliding from affecting the detection effect, which is convenient to use and more practical.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
