DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1-5, including a base 1. One end of a slide bar 9 is fixedly connected to the top of the base 1 through a support plate. The outer surface of one side of the middle part of the slide bar 9 is slidably connected to the inner wall of one end of a push plate 4. By sliding the inner wall of one end of the push plate 4 on the outer surface of one side of the middle part of the slide bar 9, the angle during the movement of the push plate 4 can be fixed, improving the stability of the push plate 4 during movement. The top of the base 1 is fixedly connected to the bottom of a motor 2 through a fixed block. One end of the motor 2 is fixedly connected to one end of a threaded rod 3. The outer surface of one side of the middle part of the threaded rod 3 is threadedly connected to the inner wall of the middle part of the push plate 4. The number of push plates 4 is two. The inner walls of the middle parts of the two push plates 4 are respectively threadedly connected to the outer surfaces of both sides of the middle part of the threaded rod 3. The thread directions of the inner walls of the middle parts of the two push plates 4 are set in opposite directions. By rotating the threaded rod 3, the two push plates 4 can be driven to move in different directions, and thus the two ends of the pipeline can be pulled. One side of one end of the push plate 4 is fixedly connected to one end of a first positioning plate 5. The outer surface of the middle part of the first positioning plate 5 is slidably connected to the inner wall of the middle part of a connecting plate 6. One side of the connecting plate 6 is fixedly connected to one end of a first spring 8. The other end of the first spring 8 is fixedly connected to one side of the push plate 4. By arranging the first spring 8, a thrust can be applied to the connecting plate 6, thereby continuously applying a pulling force to one end of the pipeline. At the same time, when the fixing claw 16 does not clamp and fix the pipeline, the movement of the push plate 4 can drive the connecting plate 6 to move through the first spring 8, and thus the fixing claw 16 clamps and fixes the pipeline. Through the arrangement of the first spring 8, when the first spring 8 is compressed, the pulling force borne by the pipeline can be determined according to the distance between the push plate 4 and the connecting plate 6. One end of the connecting plate 6 is fixedly connected to one side of a connecting frame 7. By moving the connecting frame 7, the swing rod 15 can be driven to swing, adjusting the angle of the swing rod 15, so that the fixing claw 16 moves towards the pipeline and clamps and fixes the pipeline.

[0029] The top of the base 1 is slidably connected to the bottom of the connecting frame 7 through a slide rail mechanism. The middle outer surface of the second positioning rod 10 is slidably connected to the inner wall of one side of the connecting frame 7. One end of the second positioning rod 10 is fixedly connected to one side of the fixing plate 17. One side of the fixing plate 17 is fixedly connected to one end of the second spring 18. The other end of the second spring 18 is fixedly connected to one side of the connecting frame 7. By arranging the second spring 18, a thrust can be applied to the fixing plate 17, which can drive the second positioning rod 10 to reset and maintain the position of the second positioning plate 10. Furthermore, the position of the fixing claw 16 can be maintained before detection, facilitating the pipeline to enter between the corresponding upper and lower fixing claws. At the same time, the sliding of the middle surface of the second positioning rod 10 within the inner wall of one side of the connecting frame 7 can fix the swinging amplitude of the corresponding two connecting rods 12, enabling the corresponding two connecting rods 12 to move with the same amplitude. One end of the second positioning rod 10 is fixedly connected to one side of the limiting plate 11. One end of the limiting plate 11 is rotatably connected to the inner wall of one end of the connecting rod 12 through a U-shaped frame. The inner wall of the other end of the connecting rod 12 is rotatably connected to one side of the limiting frame 13 through a U-shaped frame. The middle inner wall of the limiting frame 13 is slidably connected to the middle outer surface of one side of the limiting rod 19. One end of the limiting rod 19 is fixedly connected to one end of the inner wall of the middle part of the connecting frame 7. By sliding the middle inner wall of the limiting frame 13 on the middle outer surface of one side of the limiting rod 19, the movement trajectory of one end of the connecting rod 12 when swinging can be fixed, improving the stability of the connecting rod 12 during movement. The other side of the limiting frame 13 is fixedly connected to one side of the first positioning plate 14 through a fixing rod. The two ends of one side of the first positioning plate 14 are respectively rotatably connected to the inner walls of one ends of two swinging rods 15 through two rotating rods. The two corresponding swinging rods 15 are equal in length and arranged in parallel. By arranging the two corresponding swinging rods 15 in parallel, the angle of movement of the fixing claw 16 can be fixed, enabling the fixing claw 16 to fit more stably on the outer surface of the pipeline. One end of the other side of the first positioning plate 14 is rotatably connected to the inner wall of one end of the swinging rod 15 through a rotating rod. The inner wall of the other end of the swinging rod 15 is rotatably connected to one end of one side of the fixing claw 16 through a U-shaped frame.

[0030] The top of the base 1 is fixedly connected to one end of the telescopic outer tube 20 through a support plate. One end of the inner wall of the telescopic outer tube 20 is fixedly connected to one end of the third spring 23. The other end of the third spring 23 is fixedly connected to one end of the telescopic inner rod 21. By arranging the third spring 23, a thrust can be applied to the telescopic inner rod 21, and then a thrust can be applied to the second positioning plate 22, so that when the first positioning plate 14 moves towards the second positioning plate 22 before the fixing claws 16 clamp and fix the pipeline, the second positioning plate 22 can remain stationary, support the middle part of the swing rod 15, and enable the swing rod 15 to swing smoothly. The inner wall of the other end of the telescopic outer tube 20 is slidably connected to the outer surface of one end of the telescopic inner rod 21. The telescopic inner rod 21 and the telescopic outer tube 20 can contract when the pipeline cannot bear the applied tensile force, so that the swing rod 15 and the fixing claws 16 can smoothly move while maintaining the angle of fixing the pipeline when the pipeline cannot bear the applied tensile force, avoiding affecting the tensile test result of the pipeline. The other end of the telescopic inner rod 21 is fixedly connected to one side of the second positioning plate 22 through a fixing frame. One end of the other side of the second positioning plate 22 is rotatably connected to the inner wall of the middle part of the swing rod 15 through a rotating rod.

[0031] The electrical components appearing in this article are all electrically connected to the external main controller and the 220V mains power supply, and the main controller can be a conventional known device such as a computer for control.

[0032] During use, place the pipeline to be detected on the placement rack provided at the top of the base 1. The motor 2 starts to work, driving the threaded rod 3 to rotate, causing the two push plates 4 to move in opposite directions, and the distance between the two push plates 4 gradually begins to increase. When the push plate 4 moves, it drives the connecting plate 6 to move through the first spring 8, causing the connecting frame 7 to move through the slide rail mechanism at the top of the base 1, and the distance between the two connecting frames 7 gradually begins to increase. When the connecting frame 7 moves, it drives the first positioning plate 14 to move through the cooperation of the limiting rod 19 and the limiting frame 13, causing the swing rod 15 to swing with the second positioning plate 22 as the fulcrum. When the swing rod 15 swings, it drives the inner wall of the middle part of the limiting frame 13 to slide on the outer surface of one side of the middle part of the limiting rod 19, and then the connecting rod 12 swings. The limiting plate 11 starts to drive the outer surface of the middle part of the second positioning rod 10 to slide inside the inner wall of one side of the connecting frame 7, squeezing the second spring 18. Through the swing of the swing rod 15, the fixing claw 16 can be driven to move towards the pipeline until one side of the fixing claw 16 is in close contact with the outer surface of one side of the pipeline, enabling the corresponding upper and lower two fixing claws 16 to cooperate with each other to clamp and fix the pipeline. The motor 2 continues to work, causing the distance between the two push plates 4 to continue to increase. Since the fixing claw 16 has clamped and fixed the pipeline, when the push plate 4 moves, it will not drive the connecting plate 6 to move through the first spring 8, and will gradually squeeze the first spring 8. The extrusion force received by the first spring 8 will exert a thrust on the connecting plate 6, and then the fixing claws 16 corresponding to both ends of the pipeline will exert a pulling force on both ends of the pipeline. Determine the tensile force borne by the pipeline according to the distance between the push plate 4 and the connecting plate 6.
