The application relates to the technical field of teaching instruments, and discloses an interactive teaching instrument and a use method thereof, which comprise a supporting assembly, the top of the supporting assembly is provided with a fixing assembly, the top of the fixing assembly is provided with an adjusting assembly, one side of the adjusting assembly is provided with a display assembly, the display assembly is provided with a light-shielding assembly, the supporting assembly comprises a base, pressure sensors are arranged at the lower ends of the four corners of the base, the fixing assembly comprises a fixing plate, the adjusting assembly comprises a rotating motor arranged at the bottom of the fixing plate, the application can flexibly adjust the angle position, effectively reduce the reflection, avoid affecting the teaching effect, actively remove dust from the display component, improve the display definition, timely intervene when the whole is in an unstable state, improve the stability of the whole, effectively protect the display component when the whole is tilted, and prevent the display component from being damaged.

The invention discloses a medical orthopedic annular casing drill, and relates to the field of medical equipment, a drill bit is provided with an inclined cutting assembly, and chip removal assemblies are arranged between a drill body and the drill bit; the inclined cutting assembly comprises a tool face, a first auxiliary rear tool face, a second auxiliary rear tool face, a first main rear tool face, a front tool face and a second main rear tool face, wherein the first main rear tool face and the front tool face intersect to form a main cutting edge; the chip removal assembly comprises an inner cavity, an inner cavity face, an inclined opening and a vent hole, the inner cavity is formed in the drill bit, the inner cavity face is obliquely arranged in the inner cavity, and the inclined opening matched with the inner cavity face is formed in one end of the vent hole. The cutting edge inclination angle ensures the sharpness of the drill bit, the axial relief angle is formed by the reference plane included angle formed by the main cutting edge and the central axis of the drill body, the situation that a tool nose is broken due to large cutting resistance is effectively prevented, and fine bone chips generated during drilling are discharged through vacuum chip suction.

This light-emitting device is provided with: a proximity detecting light source that oscillates in a single horizontal mode; a 3D shape measuring light source that has a great optical output than the proximity detecting light source, configured so as to drive independently from the proximity detecting light source and oscillates in a multiple horizontal mode; and a diffusing plate provided on the emitting path of the 3D shape measuring light source.

This invention relates to a method and system for controlling rear ambient lighting in vehicles, and a computer-readable storage medium. The method includes: acquiring rear passenger occupancy status information and rear ambient lighting music rhythm enable status information detected by onboard sensors; if the rear passenger occupancy status information indicates no occupancy, the rear ambient lighting music rhythm enable status information is invalid; and if the vehicle speed exceeds a first preset speed threshold or the vehicle travel time exceeds a first preset duration, a first control command is generated, and the rear ambient lighting is gradually dimmed from normal brightness over a second preset duration according to the first control command. This invention allows the rear ambient lighting to be turned off when the driver does not require its use, reducing energy consumption.
