The performance evaluation device for human resource management according to claim 8, characterized in that: A person can push the mobile base (1) to a desired position as required, and then manually rotate the rotating handle (403), thereby driving the threaded sleeve (401) to rotate through the rotating handle (403), and driving the threaded support rod (402) to move up and down through the rotation of the threaded sleeve (401), and driving the lifting plate (5) to move up and down through the threaded support rod (402), and driving the clipping machine (6) to move up and down through the lifting plate (5), thereby adjusting the height of the clipping machine (6); When clocking in, a person can clock in by face recognition through a face recognition camera (601), or by entering a password through a numeric keypad (602), or by recognizing a fingerprint through a fingerprint reader (603); When the face recognition punch-in is performed, when the external light is weak, the fill light (10) can be turned on for fill light. When the external light is strong, the first motor (805) drives the first gear (806) and the driving wheel (808) to rotate, and the first gear (806) drives the second gear (807) and the second rotating shaft (804) to rotate. The rotation direction of the second rotating shaft (804) is opposite to the rotation direction of the output shaft of the first motor (805). The driving wheel (808) drives the driven wheel (809) and the first rotating shaft (803) to rotate. The rotation direction of the first rotating shaft (803) is opposite to the rotation direction of the output shaft of the first motor (805). The output shafts of the first motor (805) rotate in the same direction, and the first shading plate (801) is driven to rotate through the first rotating shaft (803), and the second shading plate (802) is driven to rotate through the second rotating shaft (804). The second shading plate (802) and the first shading plate (801) rotate in opposite directions, thereby adjusting the angle between the two second shading plates (802) and the first shading plate (801), and adjusting the side light through the second shading plate (802) and the first shading plate (801) to reduce reflections, so that the face recognition camera (601) can take clearer pictures; After a period of use, the second motor (901) is started to drive the third gear (902) to rotate, and the third gear (902) is used to drive the fourth gear (903) to rotate, and the fourth gear (903) is used to drive the transmission shaft (904) to rotate, and the transmission shaft (904) is used to drive the rotating plate (905) and the cleaning cotton (906) to rotate, so that the cleaning cotton (906) sweeps from the front side of the face recognition camera (601) to clean the dust accumulated on the face recognition camera (601). After long-term use, the cleaning cotton (906) can be removed for cleaning.
