In the following, the applicant will refer to the attached drawings 1-4 and the specific composition of a rotatable crystal lamp of the present application described above to describe in detail a method of using the rotatable crystal lamp of the present application: When the crystal lampshade 23 needs to rotate, the motor 22 works to drive the transmission shaft 33 clockwise. The lower end of the flat key 25 is not located in the receiving groove 31. One end of the trapezoidal block 41 is located in the transmission groove 38. The rotation of the transmission shaft 33 drives the third pulley 36. With the rotation of the first pulley 17 on the left, through the transmission of the second belt 37 and the first belt 11, the second pulley 26 and the right first pulley 17 rotate, and the second pulley 26 drives the driven shaft 10 to rotate. Restricted by the lever 27, the inclined cylinder 7 does not rotate, and the rotation of the right first pulley 17 drives the connecting rod 18 to rotate, thereby driving the crystal lampshade 23 to rotate;
When the crystal lampshade 23 requires the angle between the cover surface and the crystal lamp 24, the motor 22 works to drive the transmission shaft 33 to rotate counterclockwise, and the third pulley 36 drives the second pulley 26 to rotate counterclockwise, thereby driving the inclined cylinder 7 to rotate, thereby making the left side The first pulley 17 rises, the telescopic spring 12 compresses, the connection plate 8 drops, and the compression spring 9 returns.
