The two support rods 19 are slidably connected to the inner walls of the two finger ring built-in grooves 17. When the user needs to provide support for the tablet computer when using the protective shell, he first rotates the finger ring 15 to make the finger ring 15 slide out from the inside of the bottom groove 11 of the shell. At this time, the user can support the tablet computer by putting his finger into the finger ring 15, and the direction can be adjusted by rotating the transmission block 12, which is convenient for the user to use the tablet computer. After the finger ring 15 slides out of the bottom groove 11 of the shell, the user rotates the two transmission plates 16, and the two transmission plates 16 synchronously drive the two support rods 19 to slide out from the inner walls of the two finger ring built-in grooves 17.

At this time, the four first L-shaped buffer sheets 6 on the force-bearing surface are subjected to force first, the first telescopic rod 4 contracts, and the first spring 5 is deformed. The rebound force of the first spring 5 provides a buffering effect, reducing the impact force on the tablet computer, thereby protecting the tablet computer. Similarly, when one side of the outer surface of the tablet computer is subjected to impact force, the second L-shaped buffer sheet 10 is subjected to force first. At this time, the second telescopic rod 8 contracts, the second spring 9 is deformed, and the second telescopic rod 8 drives the limit slider to slide in the limit slide groove. The rebound force of the second spring 9 provides a buffering effect, further reducing the impact force on the tablet computer, thereby protecting the tablet computer. The protective shell has a protective effect, which greatly increases the safety of the user when using the protective shell. When the user needs to support the tablet computer when using the protective shell, the user first rotates the finger ring 15 to make the finger ring 15 slide out from the inside of the groove 11 at the bottom of the shell. At this time, the user can support the tablet computer by putting his finger into the finger ring 15, and the direction can be adjusted by rotating the transmission block 12, which is convenient for the user to use the tablet computer. After the finger ring 15 slides out from the groove 11 at the bottom of the shell, the user rotates the two transmission plates 16, and the two transmission plates 16 synchronously drive the two support rods 19 to slide out from the inner walls of the two finger ring built-in grooves 17.
