[0039] The upper end of two first connecting shafts 12 and six third connecting shafts 17 is fixedly connected with cylindrical structure for positioning, and the cylindrical structure is flat, and the inside of two third sliding slots 15 and three limit frames 16 is equipped with groove adapted to the flat upper end of first connecting shaft 12 and third connecting shaft 17.

[0040] Six protection frame connecting blocks 18 are slidably connected with corresponding second sliding slot 4 respectively, and three protection frames 10 are all "U" shape.

[0041] The upper end of detection table 1 is installed with tensile testing instrument 9, and the upper end of tensile testing instrument 9 is installed with electric wire fixing frame 8, and electric wire fixing frame 8 is shell structure, and the inside of electric wire fixing frame 8 is fixedly connected with hydraulic rod 19, and the output of hydraulic rod 19 is fixedly connected with first electric wire fixed block 20, and first electric wire fixed block 20 is slidably connected with electric wire fixing frame 8, and the bottom of electric wire fixing frame 8 is fixedly connected with second electric fixed block 22, and first electric wire fixed block 20 is "U" shape, and the upper end of second electric fixed block 22 is arc shape.

[0042] The quantity of electric wire fixing frame 8, hydraulic rod 19, first electric wire fixed block 20, non-slip pad 21 is two groups respectively symmetrically arranged in the upper end of tensile testing instrument 9 and movable frame 7.

[0044] The four corners of the detection table 1 are fixedly connected with support columns 2.

[0045] In use of the device, first, the electric wire to be detected is placed on the electric wire fixing frame 8; since the electric wire fixing frame 8, the hydraulic rod 19, the first electric wire fixing block 20 and the anti-skid pad 21 are symmetrically arranged in two groups at the upper end of the tension detector 9 and the movable frame 7, one end of the electric wire is placed in the electric wire fixing frame 8 above the tension detector 9, and the other end is placed in the electric wire fixing frame 8 above the movable frame 7; the hydraulic rod 19 is started, the output end of the hydraulic rod 19 pushes the first electric wire fixing block 20 to slide in the electric wire fixing frame 8, the first electric wire fixing block 20 is in the shape of "U" and cooperates with the second electric wire fixing block 22 in the shape of arc upper end to tightly clamp the electric wire, and the anti-skid pads 21 at the inner side and the upper end increase the friction force to prevent the electric wire from sliding in the detection process and ensure the detection accuracy.

[0046] The first driving motor 5 is started, the first driving motor 5 is fixed at the right end of the detection table 1, the output end of the first driving motor 5 drives the threaded rod 6 to rotate; the movable frame 7 threaded on the surface of the threaded rod 6 slides in the first sliding groove 3, the movable frame 7 moves to drive the connecting plate 11, the first connecting shaft 12 and other components at the bottom to move; since the connecting plate 11, the third sliding groove 15 and the first connecting shaft 12 are in two groups respectively at the bottom of the detection table 1 and the bottom of the movable frame 7, and the first connecting shaft 12 and the second connecting shaft 13 are rotatably connected with the connecting rod 14, when the movable frame 7 moves, the corresponding connecting rod 14 is driven by the first connecting shaft 12 and the second connecting shaft 13 to rotate, the first connecting shaft 12 and the second connecting shaft 13 change the distance between them in the process of rotating and moving, since the second connecting shaft 13 is fixed in the connecting plate 11, the first connecting shaft 12 can slide in the third sliding groove 15 on the surface of the connecting plate 11, the third connecting shaft 17 is driven by the connecting rod 14 to slide in the limiting frame 16, and then the protection frame connecting block 18 is driven to slide in the second sliding groove 4, so that the three "U"-shaped protection frames 10 are unfolded from the inside of the detection table 1 to surround the detection area, which not only protects the upper part of the device, but also protects the two sides of the device, expands the protection range of the device and avoids the electric wire from breaking and hurting people in the detection process.

[0047] Since the upper ends of the two first connecting shafts 12 and the six third connecting shafts 17 are fixedly connected with flat cylindrical structures, and the inner sides of the two third sliding grooves 15 and the three limiting racks 16 are provided with grooves matching the flat upper ends of the first connecting shafts 12 and the third connecting shafts 17, the first connecting shafts 12 and the third connecting shafts 17 can be stably slid in the inner sides of the corresponding third sliding grooves 15 and limiting racks 16, preventing the first connecting shafts 12 and the third connecting shafts 17 from accidentally falling off the corresponding connecting plates 11 and limiting racks 16 during use, and improving the stability of the device during use.

[0048] The first driving motor 5 is continuously operated, and the movable frame 7 continues to move away from the tension detector 9. Since the wires are fixed in the wire fixing frames 8 on the tension detector 9 and the movable frame 7 respectively, the movement of the movable frame 7 exerts tension on the wires. At this time, the tension detector 9 starts to work, and monitors the tension on the wires in real time, and displays the data. As the tension gradually increases, the wires bear the tension, and when the wires reach the breaking point, the tension detector 9 records the tension value at this time, which is the tensile strength data of the wires. In this process, the flat cylindrical structures on the upper ends of the first connecting shafts 12 and the third connecting shafts 17 match the grooves in the inner sides of the third sliding grooves 15 and the limiting racks 16, ensuring the stability and accuracy of the movement of the connecting rods 14, the movable frame 7 and other components, so that the entire detection process is smooth.

[0049] After the detection is completed, the first driving motor 5 is turned off, and the hydraulic rod 19 is started in reverse to loosen the wires from the first wire fixing block 20, making it convenient to take out the detected wires. Then, the first driving motor 5 is started again to move the movable frame 7 back to the initial position, and the protective frame 10 is also retracted, preparing for the next detection.

[0050] Further, the protective frame 10 with a U-shaped structure can simultaneously protect the upper and both sides of the device. During the wire tensile testing process, when the wires reach the breaking point, the broken wires may splatter in all directions. The protective frame 10 can block the broken wires during the splattering process, and the broken wires are blocked inside the protective frame 10, preventing them from injuring the operator or damaging other equipment on the detection table. At the same time, it can also effectively intercept the wire parts splattering to both sides, avoiding injury to the operator's body, greatly reducing the safety risk in the detection process.

[0051] By moving the protective frame 10 with the movable frame 7, automatic protection can be achieved during the wire tensile strength detection process. When detecting wires of different lengths, the movable frame 7 needs to adjust the position to meet the stretching requirement. The protective frame 10 moves with the movable frame 7, and can always match the detection area closely, ensuring the safety of each position during the detection process.
