The tension spring 33 pulls the sliding sleeve 32 to slide along the outer wall of the support rod 11, and the sliding sleeve 32 drives the rotating frame 3 to rotate through the power-assisting rod 31. The tension spring 33 is reset and stretched, driving the sliding sleeve 32 to slide upward along the outer wall of the support rod 11. The sliding sleeve 32 pushes the rotating frame 3 to rotate relative to the mounting frame 1 through the power-assisting rod 31, thereby completing the flipping and opening of the main cover 43.

Due to the principle that magnets of the same charge repel each other, the locking magnetic block 52 is pushed by the magnetic force to the elastic locking plate 51 to the locking chamber 5 moves inside to release the rotating arm. At this time, the tension spring 33 is reset and stretched, driving the sliding sleeve 32 to slide upward along the outer wall of the support rod 11. The sliding sleeve 32 pushes the rotating frame 3 to rotate relative to the mounting frame 1 through the power rod 31 to complete the flipping and opening of the mainframe cover 43.
