[0021] Reference Figures 1 to 4 A fastener tensile test fixture includes a tensile plate 10 and a tensile assembly 20. There are two tensile plates 10. A through hole 11 matching the specifications of the fastener to be tested is opened at the center of the two tensile plates 10. The fastener to be tested passes through the through holes 11 on the two tensile plates 10 to connect and fix the two tensile plates 10. The tensile assembly 20 includes two sets of load-bearing mechanisms 21. Each set of load-bearing mechanisms 21 is connected to one tensile plate 10. The load-bearing mechanisms 21 can drive the two tensile plates 10 away from each other.

[0022] It can be understood that the stretching component 20 can drive the two stretching plates 10 away from each other, thereby realizing a stretching test on the fasteners connecting the two stretching plates 10. The fastener test data can be recorded by the force applied to the stretching component 20. By adjusting the thickness of the stretching plate 10, fasteners of various specifications can be tested.

[0023] Reference Figures 1 to 4 In some embodiments of the present invention, the stretching plate 10 is a square plate. The center of the through hole 11 is located at the intersection of the diagonals of the stretching plate 10.

[0024] It is worth noting that, in some other embodiments of the present invention, the stretching plate 10 may be circular and have a corner shape that is convenient for the stretching component 20 to grasp.

[0025] Reference Figures 1 to 4 , the two stretching plates 10 are placed crosswise and overlapped at a forty-five degree angle.

[0026] It is worth noting that the two stretching plates 10 are placed at a 45-degree angle to facilitate the two sets of stretching components to be hooked to the diagonal corners of the two stretching plates 10 to apply tension to the two stretching plates 10 .

[0027] Reference Figures 1 to 4The load-bearing mechanism 21 includes a load-bearing claw 211 and a connecting column 212. The load-bearing claw 211 can be hung on the diagonal of the tensile plate 10. The connecting column 212 is set on the load-bearing claw 211. The connecting column 212 can be connected to the tensile testing machine.

[0028] It is understandable that the load-bearing claws 211 can be hooked on the diagonal corners of the tension plate 10 .

[0029] It is worth noting that, in some embodiments of the present invention, the connecting column 212 is screwed onto the load-bearing claw 211 .

[0030] It is worth noting that, in some other embodiments of the present invention, the connecting column 212 is welded to the load-bearing claw 211 .

[0031] Reference Figures 1 to 4 The connecting column 212 is provided with a pin hole 212 a.

[0032] It is understandable that the pin hole 212a can be connected to the upper and lower clamps of the tensile testing machine using a "pin" hanging connection.
