A clamping handle 803 is also fixed to the outside of the nut 813, and the clamping handle 803 is made of alloy material. The clamping handle 803 facilitates the rotation of the nut 813. A clamping head moving block 810 is fixed to the outside of each clamping head 805, and the clamping head moving block 810 is made of alloy material. The clamping head moving block 810 is used to position the clamping head moving plate 809. Each clamping head moving block 810 is slidably connected to the moving cavity 816 on the cable positioning tube 804, and the moving cavity 816 provides a moving path for the clamping head moving block 810 Each of the clamping head moving blocks 810 is provided with two moving block positioning rod positioning cavities 811, and the moving block positioning rod positioning cavities 811 provide a moving path for the moving block positioning rod 812. A moving block positioning rod 812 is slidably connected inside each of the moving block positioning rod positioning cavities 811. The moving block positioning rod 812 is made of alloy material. The moving block positioning rod 812 is used to connect the two clamping head moving plates 809. A clamping head moving plate 809 is fixed at the left and right ends of each of the moving block positioning rods 812. The clamping head moving plate 809 is made of alloy material. The clamping head moving plate 809 can prevent the clamping head 805 from tilting. Each of the clamping head moving plates 809 on the right side is fixed with a clamping A clamping head positioning rod 807, wherein the clamping head positioning rod 807 is made of alloy material, and the clamping head positioning rod 807 is used to position the clamping head moving plate 809. The right end of each clamping head positioning rod 807 is slidably connected with a clamping head positioning plate 806, and the clamping head positioning plate 806 is made of alloy material, and the clamping head positioning plate 806 is used to position the clamping head positioning rod 807. Each clamping head positioning plate 806 is fixedly connected to the cable positioning tube 804 on its inner side. A clamping head positioning spring 808 is also provided on the outside of each clamping head positioning rod 807. The clamping head positioning spring 808 is elastic, so that the clamping head 805 is tightly attached to the clamping head positioning ring 814 when no force is applied. Before using this equipment, the staff casts one end of the cable 7 into the casting block 701, and further the staff inserts the other end of the cable 7 into the cable positioning tube 804, and then inserts the cable 7 into the cable clamping tube 801, and further the staff screws the nut 813 into the outside of the screw tube 802, and further the staff twists the clamping handle 803, so that the nut 813 rotates, so that the clamping head positioning ring 814 moves to the left, so that the screw tube 802 is close to the clamping head positioning ring 814, at this time, due to the action of the clamping head positioning rod 807 and the clamping head positioning spring 808, the clamping head 805 is tightly attached to the clamping head positioning ring 814, and further the staff continues to rotate the clamping handle 803, so that the nut 813 continues to move to the left, so that the screw tube 802 is tightly attached to the clamping head 805, and then The clamping head 805 moves to the right. At this time, due to the structure of the clamping head 805 and the clamping head moving cavity 815, the clamping head 805 moves to the right and moves inward at the same time, so that the cable 7 can be clamped, thereby ensuring the stability of the equipment. At the same time, the clamping head moving block 810 moves to the right and moves inward at the same time. At this time, due to the action of the moving block positioning rod positioning cavity 811 and the moving block positioning rod 812, the clamping head moving block 810 can be parallel to the clamping head moving plate 809. At this time, due to the action of the clamping head positioning plate 806 and the clamping head positioning rod 807, the clamping head moving block 810 is always perpendicular to the axis of the cable positioning tube 804, so that the axes of multiple clamping heads 805 are the same as the axis of the cable positioning tube 804, so that the inner walls of multiple clamping heads 805 are in close contact with the cable 7, thereby ensuring the clamping effect, thereby ensuring the subsequent experimental effect.

[0023] The working process of the present invention is as follows: before using the device, the staff casts one end of the cable 7 into the casting block 701, further the staff inserts the other end of the cable 7 into the cable positioning tube 804, and then inserts the cable 7 into the cable clamping tube 801, further the staff screws the nut 813 into the outside of the screw tube 802, and further the staff twists the clamping handle 803, so that the nut 813 rotates, so that the clamping head positioning ring 814 moves to the left, so that the screw tube 802 is close to the clamping head positioning ring 814, at this time, due to the action of the clamping head positioning rod 807 and the clamping head positioning spring 808, the clamping head 805 is aligned with the The clamping head positioning ring 814 is in close contact, and the staff continues to rotate the clamping handle 803, so that the nut 813 continues to move to the left, so that the screw tube 802 is in close contact with the clamping head 805, and then the clamping head 805 moves to the right. At this time, due to the structure of the clamping head 805 and the clamping head moving cavity 815, the clamping head 805 moves to the right and moves inward at the same time, so as to clamp the cable 7, thereby ensuring the stability of the equipment. At the same time, the clamping head moving block 810 moves to the right and moves inward at the same time. At this time, due to the action of the moving block positioning rod positioning cavity 811 and the moving block positioning rod 812, the clamping head moving block 810 and the clamping head moving plate 8 09 is parallel. At this time, due to the action of the clamping head positioning plate 806 and the clamping head positioning rod 807, the clamping head moving block 810 is always perpendicular to the axis of the cable positioning tube 804, so that the axes of the multiple clamping heads 805 are the same as the axis of the cable positioning tube 804, so that the inner walls of the multiple clamping heads 805 are in close contact with the cable 7, thereby ensuring the clamping effect, thereby ensuring the subsequent experimental effect. Further, the staff opens the test box 2. At this time, the staff opens the locking plate 605 through the locking rod connecting plate 610. Further, the staff controls the handle 5 to work according to the size of the cable 7, thereby driving the moving screw 501 to work, so that the clamping The block 6 moves. At this time, the control panel 102 controls the extension and retraction of the hydraulic rod 4, so that the clamping block 6 at the left end moves. At this time, the two clamping block rollers 603 and the moving rod 503 can facilitate the movement of the clamping block 6. At the same time, the clamping block roller shaft 609 and the moving wheel shaft 506 can prevent the clamping block 6 from deflecting, thereby ensuring that the clamping block 6 always moves along the track 604, thereby ensuring that the central axes of the two clamping blocks 6 are consistent. At this time, the distance measuring ruler 904 follows the movement, so that the distance measuring disk 9 rotates, so that the moving distance of the two clamping blocks 6 is monitored through the distance measuring camera 903, so that the distance between the two clamping blocks 6 can be monitored.The staff further puts the casting block 701 into the clamping block 6 at the right end, and inserts the positioning block 8 into the clamping block 6 at the left end. The staff further loosens the locking rod connecting plate 610, so that the locking plate 605 moves inward due to the action of the locking spring 608 and the locking rod 607, so that the locking plate 605 is tightly attached to the positioning block 8 and the casting block 701, thereby preventing the positioning block 8 and the casting block 701 from sliding out, thereby ensuring the stability of the test. The control panel 102 further controls the extension and retraction of the balance rod connecting plate 301, thereby driving the two support pulleys 305 to move toward both ends. The control panel 102 further controls the extension of the balance rod 3, thereby causing the support pulley 305 to move upward, thereby causing the support pulley 305 to be tightly attached to the cable 7 and keep the cable 7 level, thereby ensuring the accuracy of the test. The staff further closes the test box cover 2 01, further, the control panel 102 controls the operation of the lighting lamp 203 and the camera 204, so as to monitor the state of the cable 7. At this time, the control panel 102 controls the hydraulic rod 4 to contract, thereby driving the left end of the clamping block 6 to move to the left, so that the cable 7 is extended. At this time, due to the action of the tension test rope 702 and the tension sensor 703, the force exerted on the two groups of the clamping block positioning rods 601 can be monitored, so as to monitor the force exerted on the cable 7. When the force exerted on the cable 7 exceeds its maximum bearing capacity, it breaks. At this time, the camera 204 can monitor its breakage, and the control panel 102 can monitor the force exerted on the cable 7 at this time. Further, the clamping block 6 has an impulse to the outside due to inertia. At this time, due to the action of the shock absorbing rod 402 and the shock absorbing spring 403, the hydraulic rod 4 can be prevented from being damaged, thereby ensuring the safety of the hydraulic rod 4, thereby improving the service life of the equipment, and completing the tension test of the cable 7. ,
