[0012] Beneficial Effects

[0013] In the prior art, due to the large size of the tablet computer, it is impossible to put it into a pocket or a small shoulder bag, and the user usually needs to hold it by hand. The size and weight of the tablet computer may affect the comfort of the user holding it with one hand for a long time. The larger screen size or the heavier tablet housing will also increase the size and weight of the device, causing hand fatigue and reducing portability. To address such problems, the utility model adopts a pull-type tablet computer housing, embeds the tablet computer into the side cover, closes the bottom cover, inserts the lock head on the connecting sleeve into the first lock groove and the second lock groove, squeezes the slide plate, rotates the pull ring 180 degrees, and the compression spring provides elastic force to make the lock head engage with the card slot. After the lock head enters the card slot, the limiting protrusion is squeezed into the limiting slide groove. After the limiting card slots on both sides of the lock head are aligned with the limiting protrusion, the limiting protrusion is engaged with the limiting card slot under the elastic force of the limiting spring, thereby improving the connection stability. The user can lift the tablet computer housing through the pull ring, thereby improving portability while preventing the housing connection from detaching, thereby reducing hand fatigue.
