[0021] The technical solution of the present utility model will be further explained below in conjunction with the accompanying drawings:

[0022] As Figures 1 - 4 shown, a winding wire tensile test device includes a workbench 1. A protection component is arranged on the workbench 1. The protection component includes a U-shaped through groove 12 opened on the workbench 1. A U-shaped protection plate 2 is slidably installed in the through groove 12. Limiting strips 21 are respectively fixed at the upper and lower ends of the protection plate 2. Such a setting avoids the protection plate 2 sliding out of the through groove 12. The two sides of the protection plate 2 are respectively connected to the two sides of the workbench 1 through limiting components.

[0023] The limiting component includes an ear wall plate 22 fixed on the side wall of the limiting strip 21. A threaded rod 7 is fixed at the lower end of the ear wall plate 22. A limiting nut 71 is threadedly sleeved on the threaded rod 7. The threaded rod 7 is sleeved on a limiting cylinder 8. The limiting cylinders 8 are respectively fixed on the two side walls of the workbench 1. A limiting disc arranged below the limiting cylinder 8 is fixed at the bottom of the threaded rod 7. Such a setting avoids the threaded rod 7 sliding out of the limiting cylinder 8. The outer diameter of the limiting nut 7 is larger than the outer diameter of the limiting cylinder 8. The upper end of the limiting cylinder 8 is higher than the upper end surface of the workbench 1. This can ensure that the two clamping components are on the same horizontal plane.

[0024] A tensile test component is arranged on the workbench 1 in the through groove 12. The tensile test component includes an electric push rod 3. A moving plate 4 is fixed at the telescopic end of the electric push rod 3. The moving plate 4 is a U-shaped plate body. The two sides of the moving plate 4 are slidably connected to sliding grooves 13. The sliding grooves 13 are opened on the two sides of the upper end surface of the workbench 1. A fixed block 11 is fixed on the workbench 1 on the side far from the electric push rod 3. The fixed block 11 is at the same height as the moving plate 4. Clamping components are respectively fixed on the fixed block 11 and the moving plate 4. The two clamping components are symmetrically arranged. The upper end of the limiting cylinder 8 is higher than the upper end surface of the workbench 1. This can ensure that the two clamping components are on the same horizontal plane.

[0025] The clamping component includes a clamping cylinder 5. The cavity 51 in the clamping cylinder 5 is arranged in a right trapezoid shape. The cross section of the clamping cylinder 5 is a right trapezoid. The right angle side is located at the bottom wall of the cavity 51, and the hypotenuse is located at the top wall of the cavity 51. A clamping block 6 is slidably installed in the clamping cylinder 5. The clamping block 6 is a block body in the shape of a right trapezoid. The clamping block 6 can be slidably installed into the cavity 51. The narrower ends of the openings of the two clamping components face each other.

[0026] A rack 52 is arranged on the bottom wall of the clamping cylinder 5. Tooth patterns 61 are opened at the bottom of the clamping block 6. The rack 52 and the tooth patterns 61 incline towards the wider part of the opening of the clamping cylinder 5. Such a setting can increase the friction force between the winding wire 9 and the clamping cylinder 5 and the clamping block 6, make the winding wire 9 clamped more firmly, and avoid falling off.

[0027] Working principle: During use, the staff place both ends of the winding wire 9 into the clamping cylinder 5, then snap the clamping block 6 into the clamping cylinder 5. The tooth pattern 61 at the bottom of the clamping block 6 contacts the winding wire 9. Then, the staff raise the protective plate 2 from the through groove 12 and fix the height of the threaded rod 7 with the limit nut 71. After that, the staff start the electric push rod 3 through the control device. The electric push rod 3 drives the moving plate 4 to move to one side. The two ends of the moving plate 4 slide in the sliding groove 13, and the moving plate 4 drives one end of the winding wire 9 to conduct a tensile test.

[0028] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
