However, the following embodiments are only the preferred embodiments of the present invention, not all of them. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work all belong to the protection scope of the present invention.

[0020] Embodiment

[0021] Please refer to Figures 1 - 3As shown in the figure, the utility model provides a strength detection device for stainless steel fasteners. The cross-sectional area of the pressing plate 12 is the same as that of the through hole 10, that is, the pressing plate 12 can pass through the through hole 10. A bracket 15 is fixedly connected to the upper end of the workbench 1. An electric telescopic rod 16 is arranged on the bracket 15. The output end of the electric telescopic rod 16 is provided with a pressure sensor 17. A pressing block 18 is arranged at the lower end of the pressure sensor 17. A controller 19 is fixedly connected to one side of the bracket 15. A display screen 20 is arranged on the controller 19. Support legs 21 are fixedly connected to the lower end corners of the workbench 1.

[0022] During use, place the stainless steel fastener on the workbench 1 and make it directly below the pressing block 18. Then start the electric telescopic rod 16. The electric telescopic rod 16 drives the pressure sensor 17 and the pressing block 18 to move downward until the pressing block 18 contacts the stainless steel fastener and applies a certain pressure to the stainless steel fastener. The pressure sensor 17 can detect the pressure applied by the pressing block 18 to the stainless steel fastener and transmit the measured value to the controller 19. The controller 19 displays the measured value on the display screen 20.

[0023] As a further implementation manner of this embodiment, as Figures 1 - 4 shown, a pair of fixing plates 2 are fixedly connected to the lower end of the workbench 1. A motor 3 is arranged on one side of the fixing plate 2. The output end of the motor 3 penetrates through the fixing plate 2 and is fixedly connected to a bidirectional lead screw 4. One end of the bidirectional lead screw 4 is rotatably connected to the fixing plate 2. A pair of limiting plates 5 are threadedly connected to the bidirectional lead screw 4. A pair of limiting holes 6 are formed in the workbench 1. The lengths of the two limiting holes 6 are the same. One end of each of the two limiting plates 5 penetrates through the limiting hole 6 and is fixedly connected to a placing block 7. A placing groove 8 is formed in the placing block 7. A connecting block 9 is placed in the placing groove 8. A through hole 10 is formed in the connecting block 9. A threaded rod 11 is fixedly connected to the placing block 7. A pressing plate 12 is threadedly connected to the threaded rod 11. A square clamping plate 13 and an arc-shaped clamping plate 14 are respectively arranged on the two connecting blocks 9.

[0024] During use, by starting the motor 3, the motor 3 drives the bidirectional lead screw 4 to rotate. The rotation of the bidirectional lead screw 4 drives the two limit plates 5 to move towards each other. And under the limiting action of the limit holes 6, the limit plates 5 can move more stably. The movement of the limit plates 5 drives the placement block 7, the connecting block 9 and the square clamping plate 13 to move together until the square clamping plate 13 clamps and fixes the stainless-steel fastener. When it is necessary to clamp and fix stainless-steel fasteners such as round nuts and round washers, the pressing plate 12 can be rotated 90 degrees so that the pressing plate 12 no longer presses and fixes the connecting block 9. At the same time, the pressing plate 12 coincides with the through hole 10 in the vertical direction. At this time, the connecting block 9 with the square clamping plate 13 can be moved upward, taken out from the placement groove 8 of the placement block 7, and the connecting block 9 with the arc-shaped clamping plate 14 is placed in its placement groove 8. Then rotate the pressing plate 12 90 degrees in the reverse direction so that the pressing plate 12 presses and fixes the connecting block 9, thereby realizing the replacement of the square clamping plate 13 with the arc-shaped clamping plate 14, and being able to clamp and fix the stainless-steel fasteners such as round nuts and round washers well, thus improving the scope of use of the device.

[0025] Specific working principle: During use, first place the stainless-steel fastener on the workbench 1 and make it directly below the pressing block 18. Then, by starting the motor 3, the motor 3 drives the bidirectional lead screw 4 to rotate. The rotation of the bidirectional lead screw 4 drives the two limit plates 5 to move towards each other. And under the limiting action of the limit holes 6, the limit plates 5 can move more stably. The movement of the limit plates 5 drives the placement block 7, the connecting block 9 and the square clamping plate 13 to move together until the square clamping plate 13 clamps and fixes the stainless-steel fastener. When it is necessary to clamp and fix stainless-steel fasteners such as round nuts and round washers, the pressing plate 12 can be rotated 90 degrees so that the pressing plate 12 no longer presses and fixes the connecting block 9. At the same time, the pressing plate 12 coincides with the through hole 10 in the vertical direction. At this time, the connecting block 9 with the square clamping plate 13 can be moved upward, taken out from the placement groove 8 of the placement block 7, and the connecting block 9 with the arc-shaped clamping plate 14 is placed in its placement groove 8. Then rotate the pressing plate 12 90 degrees in the reverse direction so that the pressing plate 12 presses and fixes the connecting block 9, thereby realizing the replacement of the square clamping plate 13 with the arc-shaped clamping plate 14, and being able to clamp and fix the stainless-steel fasteners such as round nuts and round washers well, thus improving the scope of use of the device. When the stainless-steel fastener is fixed, then start the electric telescopic rod 16. The electric telescopic rod 16 drives the pressure sensor 17 and the pressing block 18 to move downward until the pressing block 18 contacts the stainless-steel fastener and applies a certain pressure to the stainless-steel fastener. The pressure sensor 17 can detect the pressure applied by the pressing block 18 to the stainless-steel fastener and transmit the measured value to the controller 19. The controller 19 displays the measured value on the display screen 20, thereby finally realizing the detection of the strength of the stainless-steel fastener.
