The circular ring sleeve 32 is sleeved on the rotating arm 31, and the center of the circular ring sleeve 32 coincides with the rotation center of the rotating arm 31, so that the circular ring sleeve 32 can rotate freely 360° in the same area with the rotating arm 31, and the force-bearing area will not change, so as to ensure stable support for the protective cover 2. Secondly, the positioning device 33 is used to position the rotation of the rotating arm 31, so that the rotating arm 31 can be positioned at any position, so as to achieve support in different directions and meet the different viewing angles of the user.

[0026] The positioning device 33 includes an elastic positioning member 331 fixedly mounted on the rotating arm 31, a rotating sleeve 332 passing through the protective sleeve 2 and sleeved on the elastic positioning member 331, and a limiting cover plate 333 passing through the rotating sleeve 332 and fixed on the rotating arm 31, wherein the elastic positioning member 331, the rotating sleeve 332 and the limiting cover plate 333 are located at the rotation center of the rotating arm 31, and the outer side of the elastic positioning member 331 is in elastic contact with the inner wall of the rotating sleeve 332. The elastic positioning member 331 is installed on the rotating arm 31 so that the elastic positioning member 331 can rotate with the rotating arm 31, and the elastic positioning member 331 is elastically pressed against the inner wall of the rotating sleeve 332, so that the rotating arm 31 can be stably positioned after any rotation, thereby ensuring that the rotating support module 3 can stably support the protective sleeve 2 at any angle.

[0027] The rotating arm 31 is provided with a first installation slot 311 for installing the locking device 33 at the rotation center. The center of the first installation slot 311 is provided with a central positioning column 312 for sleeve-mounting the elastic locking member 331. The outer wall of the central positioning column 312 is provided with a plurality of first convex strips 312A for positioning and locking the elastic locking member 331. The elastic locking member 331 is sleeved on the central positioning column 312 and is clamped and fixed with the first convex strips 312A. The elastic locking member 331 is annular, and a plurality of first locking grooves 331A for locking and fixing with the first convex strips 312A are provided on the inner wall thereof. The outer wall of the elastic locking member 331 is provided with a plurality of first elastic force arms 331B that can elastically press against the inner wall of the rotating sleeve 332. The inner wall of the rotating sleeve 332 is provided with a plurality of second locking grooves 332A that can match and lock with the first elastic force arms 331B. The elastic locking member 331 is provided with a plurality of first elastic force arms 331B to press against the inner wall of the rotating sleeve 322, and a plurality of second locking grooves 332A are provided in the rotating sleeve 332 for matching and locking the first elastic force arms 331B, so that the rotating arm 31 can further achieve stable support at several commonly used angles, avoiding the deflection of the rotating arm 31 caused by long-term use or force, thereby greatly improving the stability of the support.

[0028] The elastic locking member 331 is provided with four first elastic force arms 331B on the periphery, and the number of the second locking grooves 332A on the inner wall of the rotating sleeve 332 is greater than the first elastic force arms 331B; the limit cover plate 333 is fixed to the central positioning column 312 by screws 334. One side of the circular ring sleeve 32 is disconnected and elastically buckled to one end of the rotating arm 31, and the rotating arm 31 is provided with a first hinge 34 and a second hinge 35 respectively for buckling with the two ends of the circular ring sleeve 32, and the first hinge 34 and the second hinge 35 can be positioned at any angle. The circular ring sleeve 32 and the rotating arm 31 are connected by the first hinge 34 and the second hinge 35, so that the circular ring sleeve 32 can be bent at any angle relative to the rotating arm 31, and the rotating arm 31 cannot be easily bent to swing, and it can be supported at multiple angles.

[0029] The first hinge 34 includes a hinge seat 341 fixed on the rotating arm 31, a hinge shaft 342 rotatably mounted on the hinge seat 341 and used to buckle with the end of the annular sleeve 32, a plurality of damping plates 343 sleeved on the hinge shaft 342, and a locking nut 344 used to fix the hinge shaft 342 on the hinge seat 341, wherein the locking nut 344 is located on one side of the damping plate 343 and can adjust the damping coefficient; the second hinge 35 has the same structure as the first hinge 34 and is symmetrically installed. The damping plates 343 are disc springs and are sleeved on the hinge shaft 342 in a symmetrical manner; the hinge shaft 342 passes through the hinge seat 341, and the hinge seat 341 is also sleeved with positioning gaskets 345 located on both sides of the hinge seat 341. One side of the protective cover body 2 is also provided with a second installation groove 21 for installing the pen 6. By sleeved a plurality of damping plates 343 on the hinge shaft 342 and using the locking nut 344 to squeeze the damping plates 343, the frictional resistance between the damping plates 342 and the hinge seat 341 is increased, resulting in an increase in the force required for the hinge shaft 342 to rotate. The frictional force brought by the damping plates 342 allows the annular sleeve 32 to remain stable after swinging at any angle, thereby achieving the annular sleeve 32 supporting the protective sleeve body 2 at any angle.

[0030] To sum up, when the utility model is working, the tablet computer 1 is transferred into the protective cover body 2, and the back panel and the frame of the tablet computer 1 are wrapped by the protective cover body 2 to play a protective role; further, when it is needed to support and use, the circular ring sleeve 32 of the rotating support assembly 3 is pulled, and then the rotating arm 31 is pushed to rotate by the circular ring sleeve 32, so that the circular ring sleeve 32 is in a suitable direction, and then the circular ring sleeve 32 is bent to make the tablet computer 1 at a suitable tilt angle; further, when it is necessary to fold the support, it is only necessary to bend the circular ring sleeve 32 to fit it to the back of the protective cover body 2. Since the circular ring sleeve 32 is mounted on the rotating arm 31, no matter how the rotating arm 31 rotates, it will always be in the circular ring sleeve 32, so the circular ring sleeve 32 can be folded in any direction without being affected by the position after rotation.
