[0028] There are two vertical plates 12, and mounting holes are opened on both sides of the vertical plates 12. The inner walls of the mounting holes opened in the vertical plates 12 are installed with a rotating fixing device 9, and the rotating fixing device 9 includes a rotating rod 91, a rotating disk 92, an abutment groove 93, a rotating handle 94, a connecting rod 95, an abutment block 96, a first spring 97, and a pressing handle 98.

[0029] A turntable 92 is fixedly installed on the outer wall of the rotating rod 91, a contact groove 93 is fixedly connected to one side of the rotating rod 91, a rotating handle 94 is fixedly connected to the side of the contact groove 93 away from the rotating rod 91, the rotating handle 94 is movably connected to the inner wall of the mounting hole opened in the vertical plate 12, an abutment block 96 is movably provided on the outer wall of the abutment groove 93, a connecting rod 95 is fixedly connected to the top of the abutment block 96, a pressing handle 98 is fixedly connected to the top of the connecting rod 95, the pressing handle 98 and the vertical plate 12 are elastically connected via a first spring 97, one end of the first spring 97 is fixed to the lower surface of the pressing handle 98 and the other end is fixed to the upper surface of the vertical plate 12.

[0031] The working principle of the seal imprint recognition device mainly involves steps such as image acquisition, image processing and feature extraction. First, the device uses an infrared scanning head 11 to scan the seal and obtain image information on the seal surface. The acquired image may be affected by factors such as lighting and angle, and needs to be preprocessed to improve the image quality. This includes operations such as removing noise, enhancing contrast, and adjusting brightness. When recognizing the seal imprint, the seal background and the imprint part need to be separated. Image segmentation technology can help accurately extract the seal imprint and pattern from the background. Next, the device will extract features of the segmented seal imprint. These features may include information such as the shape, size, and outline of the imprint, as well as features such as the stroke structure and color of the imprint. By comparing the extracted features with the features in the known seal imprint database, the identity and authenticity of the seal are determined. This usually involves the application of pattern recognition and machine learning algorithms. Finally, the device outputs the recognition result and displays or records the seal imprint content, pattern and other information on the display screen 8. In this way, the user can perform corresponding authentication, authorization and other operations on the electronic document.

[0032] Working principle: When the seal imprint recognition device of the utility model needs to be used, when the height needs to be adjusted, the first steel ball 411 and the second steel ball 412 are pressed at the same time, and under the action of the spring force of the second spring 413, the first movable rod 3 slides on the inner wall of the first fixed rod 2 until the first steel ball 411 and the second steel ball 412 are just engaged with the first card slot 4 to achieve height adjustment. When the horizontal length needs to be adjusted, the third steel ball 711 and the fourth steel ball 712 are pressed at the same time, and under the action of the spring force of the third spring 713, the second movable rod 3 slides on the inner wall of the first fixed rod 2 until the first steel ball 411 and the second steel ball 412 are just engaged with the first card slot 4 to achieve height adjustment. The rod 6 slides on the inner wall of the second fixed rod 5 until the third steel ball 711 and the fourth steel ball 712 are just engaged with the second slot 7 to achieve horizontal adjustment. When rotation scanning is required, press the pressing handle 98, and under the action of the spring force of the first spring 97, the abutment block 96 is no longer in contact with the abutment slot 93. At the same time, the rotating handle 94 in the rotating fixing device 9 is manually twisted to make the turntable 92 drive the infrared scanning head 11 to rotate, which can realize multi-angle scanning and the recognition of seals and imprints, ensure the accuracy of scanning, improve the recognition efficiency, and reduce paper waste.
