[0036] A driving sprocket 109 meshing with the driven teeth 104 is arranged on the outside, and a transmission gear 111 is arranged in the class plate housing 1. The transmission gear 111 and the driving sprocket 109 are connected through a reversing transmission box 110. The interior of the reversing transmission box 110 is composed of structures such as gears and transmission shafts, which can transmit power. An inclined spring piece 112 is arranged on the surface of the rotating sleeve 6, and a one-way ratchet 113 meshing with the inclined spring piece 112 is arranged on the outside, and a ratchet center shaft 114 is fixedly arranged on the surface of the fulcrum seat 4.

[0039] When the present invention is in use, the class nameplate shell 1 is fixed at the classroom door through the installation ear 119, and the class nameplate information is displayed through the display screen 3. At this time, the information recognition lens 10 performs statistical recognition on the facial information of the students to complete automatic sign-in and personnel statistics. At the same time, the information recognition lens 10 detects the distribution of personnel on both sides of the class nameplate shell 1 in real time. When and only when there are personnel activities on one side of the information recognition lens 10, the electromagnet module 8 on the corresponding side is energized, so that the electromagnet module 8 has magnetic force. Through the magnetic attraction of the electromagnet module 8 and the magnetic metal plate 7, the display screen 3 overcomes the elastic force of the reset spring 9, and then the display screen 3 rotates around the swing fixed axis 5 and deflects toward the side where there are personnel activities, thereby improving the visibility of the display screen 3.

[0040] When the locking plate 303 is in the locked state, the locking plate 303 is locked in the locked state.

[0041] As the display screen 3 deflects back and forth, the rotating sleeve 6 reciprocates and rotates. When the rotating sleeve 6 rotates, the one-way ratchet 113 can be pushed to rotate by the inclined spring piece 112. When the rotating sleeve 6 reverses, the one-way ratchet 113 cannot rotate through the one-way meshing of the vertical plate bevel teeth 116 and the one-way ratchet 113. At this time, tooth jump occurs between the inclined spring piece 112 and the one-way ratchet 113, so that the one-way ratchet 113 exhibits one-way rotation; the one-way ratchet 113 drives the transmission gear 111 to rotate through the sleeve gear 118, and the transmission gear 111 transmits power to the drive gear 111 through the reversing transmission box 110. The movable gear plate 109 controls the rotation of the glass rotating cover 101; when the glass rotating cover 101 rotates, the elastic scraper 105 automatically cleans the surface of the glass rotating cover 101, so that the information recognition lens 10 can automatically keep a clean state and reduce maintenance; when the blocking protrusion 108 contacts the elastic scraper 105, the blocking protrusion 108 can push the elastic scraper 105 to bend and deform until the blocking protrusion 108 passes through the scraper notch 107, and the elastic scraper 105 elastically resets, so that the resetting elastic force of the elastic scraper 105 is used to remove the dust accumulated on the surface of the elastic scraper 105 and the contact cotton pad 106.
