The protective cover 1 is provided with jacks 9 at both ends of the corresponding sleeve 8. The rotating placement plate 2 drives the hand-drawing board body 4 to rotate. After adjusting to a suitable angle, the support rod 5 and the straight rod 6 are rotated. The straight rod 6 is clamped between two adjacent abutment blocks 7 to fix the position of the hand-drawing board body 4 after rotation. The rotating torsion block 15 drives the threaded rod 12 to rotate between the bottom plate 10 and the top plate 11. The rotation of the threaded rod 12 drives the moving block 13 to slide at the movable opening 14. The sliding of the moving block 13 drives the hand-drawing board body 4 to move in the accommodating groove 3. The height of the hand-drawing board body 4 can be adjusted to meet the viewing angle requirements of users of different heights. It is highly practical. Then the protective cover 1 is placed on the desktop for drawing operations. It has a simple structure and is easy to operate.

[0019] Furthermore, the lifting assembly includes a bottom plate 10, a top plate 11, a threaded rod 12 and a moving block 13. The bottom plate 10 and the top plate 11 are fixedly connected at the middle position of the placement plate 2. The top plate 11 is vertically located above the bottom plate 10. The threaded rod 12 is rotatably connected between the bottom plate 10 and the top plate 11. The moving block 13 is threadedly connected to the threaded rod 12. A movable opening 14 is opened at the position of the placement plate 2 corresponding to the moving block 13. One side of the moving block passes through the movable opening 14 and is fixedly connected to the hand-drawing board body 4.

[0020] Furthermore, one end of the threaded rod 12 passes through the bottom of the base plate 10 and is fixedly connected to a twisting block 15 to facilitate the rotation operation of the threaded rod 12 .

[0021] Furthermore, the limiting assembly includes a fixed block 16, a return spring 17, a limiting block 18, a movable rod 19, a connecting plate 20 and a plug plate 21. The fixed block 16 is fixedly connected in the sleeve 8, one end of the return spring 17 is fixedly connected on both sides of the fixed block 16, the other end of the return spring 17 is fixedly connected to the limiting block 18, the limiting block 18 is slidably connected in the sleeve 8, the side of the limiting block 18 away from the return spring 17 is fixedly connected to one end of the movable rod 19, the other end of the movable rod 19 passes through the outside of the sleeve 8 and is fixedly connected to the connecting plate 20, the bottom of the connecting plate 20 is fixedly connected to the plug plate 21, the plug plate 21 matches the socket 9, and when no operation is required When drawing, pull the connecting plate 20 to drive the plug plate 21 away from the socket 9, the movable rod 19 moves toward the outside of the sleeve 8, the limiting block 18 slides in the sleeve 8 to drive the reset spring 17 to be stretched, and the rotating placement plate 2 drives the hand-drawn board body 4 to fit inside the protective cover 1, and the force applied to the connecting plate 20 is cancelled. The reset spring 17 automatically contracts and drives the movable rod 19 and the limiting block 18 back to their original positions. The plug plate 21 passes through the socket 9 and fits on the surface of the hand-drawn board body 4, which can fix the hand-drawn board body 4 inside the protective cover 1, reducing the possibility of the hand-drawn board body 4 rotating again due to accidental pulling, thereby improving the protection of the hand-drawn board body 4.

[0022] Furthermore, the width of the limiting block 18 is greater than the width of the opening of the sleeve 8 , thereby preventing the return spring 17 from being stretched to the outside of the sleeve 8 .

[0023] Furthermore, a non-slip pad is fixedly connected to one side of the plug board 21 close to the hand-painted board body 4 , and the provision of the non-slip pad increases the anti-slip property between the plug board 21 and the hand-painted board body 4 .

[0024] Working principle: When in use, rotate the placement plate 2 to drive the hand-drawing board body 4 to rotate. After adjusting to a suitable angle, rotate the support rod 5 and the straight rod 6. The straight rod 6 is clamped between two adjacent abutment blocks 7 to fix the position of the hand-drawing board body 4 after rotation. Rotate the twisting block 15 to drive the threaded rod 12 to rotate between the bottom plate 10 and the top plate 11. The rotation of the threaded rod 12 drives the moving block 13 to slide at the movable opening 14. The sliding of the moving block 13 drives the hand-drawing board body 4 to move in the accommodating groove 3. The height of the hand-drawing board body 4 can be adjusted to meet the viewing angle requirements of users of different heights. It is highly practical. Then the protective cover 1 is placed on the desktop for drawing operations. It has a simple structure and is easy to operate.

[0025] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
