[0023] In this implementation:

[0024] Furthermore, a through hole 23 is provided inside the second mounting plate 9, and a mounting hole 26 is provided on the top of the second mounting plate 9. The mounting hole 26 is connected to the through hole 23, and a pressure rod 25 is installed inside the mounting hole 26. A third clamping plate 24 is installed at the bottom of the pressure rod 25. The third clamping plate 24 can clamp the wires and make the third clamping plate 24 contact with the wire plug.

[0025] Furthermore, a fixing nut 21 is installed on the top of the first mounting plate 8 away from the fixing plate 4, and a fixing bolt 22 is installed on the internal thread of the fixing nut 21, and a second clamping plate 20 is installed on the bottom of the fixing bolt 22. A first clamping plate 19 is installed on the top of the first mounting plate 8 close to the fixing nut 21. The fixing bolt 22 is rotated clockwise so that the fixing bolt 22 moves downward through the thread, and the fixing bolt 22 drives the second clamping plate 20 to move together, so that the first clamping plate 19 and the second clamping plate 20 clamp the wires, thereby fixing the wires.

[0026] Furthermore, a bearing 16 is installed at one end of the mounting chamber 1 away from the servo motor 3, and a connecting rod 15 is installed inside the bearing 16. The end of the connecting rod 15 away from the bearing 16 is connected to the threaded rod 11, so that both ends of the threaded rod 11 can be firmly installed, making the rotation of the threaded rod 11 more stable.

[0027] Furthermore, a top plate 28 is installed on the top of the pressure rod 25, and fixing springs 27 are installed at both ends of the bottom of the top plate 28. The ends of the fixing springs 27 away from the top plate 28 are connected to the second mounting plate 9.

[0028] Furthermore, a telescopic spring 5 is installed at the bottom of the first mounting plate 8 away from the through-hole 10, and the end of the telescopic spring 5 away from the first mounting plate 8 is connected to the fixed plate 4. The telescopic spring 5 applies a reaction force to the first mounting plate 8, and the electric wire plug can be stretched through the first mounting plate 8, so that a load test can be performed on the electric wire plug.

[0029] Furthermore, a second sliding component 12 is installed at the bottom of the installation bin 1, and a guide slider 14 is slidably installed on the top of the second sliding component 12. The end of the guide slider 14 away from the second sliding component 12 is connected to the threaded tube 13. The threaded tube 13 is limited by the guide slider 14 to prevent the threaded tube 13 from rotating with the threaded rod 11.

[0030] Working principle:

[0031] When in use, the device is powered on, and the wire on the wire plug is passed through the through hole 23. At this time, the elastic action of the fixing spring 27 causes it to pull the top plate 28 to move downward, and the top plate 28 drives the third clamping plate 24 to move through the pressure rod 25, so that the third clamping plate 24 is closely fitted with the wire, and the wire can be clamped by the third clamping plate 24, and the third clamping plate 24 is in contact with the wire plug;

[0032] Then place the wire between the first clamping plate 19 and the second clamping plate 20, and turn the fixing bolt 22 clockwise so that the fixing bolt 22 moves downward through the thread, and the fixing bolt 22 drives the second clamping plate 20 to move together, so that the first clamping plate 19 and the second clamping plate 20 clamp the wire, and the wire can be fixed;

[0033] When performing a load test, the staff can start the servo motor 3 through the control panel 17, so that the servo motor 3 drives the threaded rod 11 to rotate clockwise, and the threaded tube 13 outside the threaded rod 11 is limited by the guide slider 14, so that the threaded tube 13 cannot move with the threaded rod 11, so that the threaded tube 13 can only move outside the threaded rod 11 through the thread;

[0034] At this time, the threaded tube 13 drives the guide slider 14 to slide along a straight line on the second sliding assembly 12, and the threaded tube 13 drives the second mounting plate 9 to move together, so that the third clamping plate 24 pushes the wire plug to move together;

[0035] When the wire plug moves through the second mounting plate 9, the first mounting plate 8 is moved together by the pulling force of the wire, so that the first mounting plate 8 stretches the telescopic spring 5. At this time, the telescopic spring 5 applies a reaction force to the first mounting plate 8, and the wire plug can be stretched through the first mounting plate 8, and a load test can be performed on the wire plug;

[0036] During the experiment, the tension sensor 6 monitors the tensile force exerted on it by the first mounting plate 8 in real time, and displays the specific tension value on the display 18 through the controller 2, so that the staff can always know the load size of the wire plug. The experimental process is relatively convenient to operate and the device is relatively convenient to use.

[0037] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
