[0002] Face recognition technology is widely used in identity verification tools related to privacy or security, mainly including two parts: the facial feature extraction part and the feature comparison and matching part. In recent years, with the development of deep learning technology, in the facial feature extraction part, based on the artificial neural network model, the practice of guiding feature learning of the model through supervision signals has become increasingly common, effectively improving the accuracy of face recognition;

[0003] Existing devices are prone to failure to recognize due to position mismatch when recognizing faces, or one needs to often bend down to face the device. Therefore, we propose a height-adjustable face recognition device. Summary of the Invention

[0004] The purpose of the present invention is to provide a height-adjustable face recognition device, which solves the problems that existing devices are prone to failure to recognize due to position mismatch when recognizing faces, or one needs to often bend down to face the device, through a lifting mechanism and a shock absorption and buffering mechanism.

[0005] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0007] The lifting mechanism includes a concave chute, which is opened inside the protective housing. A moving rack is slidably connected to the inner wall of the concave chute. A fixed shaft rod is fixedly connected to the inner wall of the protective housing. A rotating gear is fixedly connected to the middle axis of the outer wall of the fixed shaft rod. The rotating gear meshes with the moving rack. A small shaft rod is rotatably connected inside the protective housing. The small shaft rod penetrates through the inner wall of the protective housing and extends to the outside. A small gear is fixedly connected to the outer wall of the small shaft rod. The small gear meshes with the rotating gear. A handle is fixedly connected to the outer wall of the small shaft rod on the side far from the protective housing. A shock absorption and buffering mechanism is arranged at the top of the connecting moving rack.

[0008] Further, the shock absorption and buffering mechanism includes a tray, the bottom of the tray is fixedly connected to the top of the moving rack, and a thickened frame is fixedly connected to the top of the tray.

[0009] Further, a hexagonal groove block is fixedly connected inside the thickened frame, and a long-axis smooth rod is fixedly connected to the inner wall of the hexagonal groove block.

[0010] Further, a shock-absorbing telescopic spring is sleeved on the outer wall of the long-axis smooth rod. The upper end of the shock-absorbing telescopic spring is fixedly connected with a pressing and reinforcing piece, and a compression module is fixedly connected to the top of the pressing and reinforcing piece.

[0011] Further, a circular chassis is fixedly connected to the top of the tray, a fixing block is fixedly connected to the upper surface of the circular chassis, and an empty groove is opened on the front surface of the fixing block.
