[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Example 1

[0027] Reference Figure 1-Figure 3 A detection device includes a base 1, a placement plate 2, a first inverted U frame 5, a second inverted U frame 51, a clamping component, a moving component and an angle adjustment component.

[0028] A placement plate 2 is rotatably installed at the top of the base 1 for placing the leather to be tested. A second groove 9 is provided in the base 1, and two slide rods 12 are installed in the second groove 9, and a threaded plate 10 is slidably installed on the slide rod 12. A first screw rod 13 is also rotatably installed in the second groove 9, and the first screw rod 13 is threadedly connected to the threaded plate 10. One end of the first screw rod 13 extends out of the base 1 and is fixed with a turning handle 8. The top of the threaded plate 10 is connected to two support rods 11 through a hinge shaft, and the other end of the support rod 11 is connected to the bottom end of the placement plate 2 through a hinge shaft. By rotating the turning handle 8, the first screw rod 13 can be driven to rotate, thereby driving the threaded plate 10 to slide along the slide rod 12, and the inclination angle of the placement plate 2 can be adjusted by the leverage of the support rod 11 to adapt to different testing requirements.

[0029] The first inverted U-frame 5 is fixed to the side end of the placement plate 2, and the second inverted U-frame 51 is connected to the placement plate 2 through a movable component. A set of clamping components is provided in each of the first inverted U-frame 5 and the second inverted U-frame 51 for positioning the leather. Each set of clamping components includes two limit rods 17 slidably installed in the inverted U-frame, and the side ends of the limit rods 17 are fixed with the same clamping plate 16. The side end of the clamping plate 16 is provided with a bolt 15 threadedly connected to the inverted U-frame. By rotating the bolt 15, the clamping plate 16 can be pushed to slide along the limit rod 17, thereby clamping or loosening the leather. In order to increase the stability and anti-slip properties of the clamping, the side end of the clamping plate 16 is also provided with a rubber anti-slip pad.

[0030] The moving assembly includes a first groove 6 defined within the placement plate 2. A threaded block 18 is slidably mounted within the first groove 6. A second screw rod 14 is also rotatably mounted within the first groove 6, with the threaded block 18 threadedly connected to the second screw rod 14. One end of the second screw rod 14 extends outside the placement plate 2 and is secured to a knob 7. Rotating the knob 7 drives the second screw rod 14, which in turn drives the threaded block 18 to slide along the first groove 6, thereby adjusting the spacing between the second inverted U-frame 51 and the first inverted U-frame 5 to accommodate leather of varying sizes.

[0031] This application can be used for leather defect detection, and can also be used in other fields applicable to this application.
