[0026] Example 1

[0027] See also Figures 1 to 6 As shown, a painting group tutoring box includes a box body 1, a propaganda board 2 and a flip cover 3 hinged on the top of the box body 1, shoulder straps 4 fixedly installed on both sides of the box body 1, a writing board 5 slidably installed inside the box body 1, a plurality of pull rods 6 hinged between the top of the box body 1 and the propaganda board 2, and a storage rack 7 fixedly installed inside the box body 1; the storage rack 7 includes slide rails 75 horizontally fixedly installed on both sides of the bottom of the box body 1, a plurality of connecting rods 72 hinged on the slide rails 75 through pins 73, the connecting rods 72 are cross-arranged through pins 73, a plurality of pencil boxes 71 hinged on the top of the plurality of connecting rods 72 through pins 73, a push plate 74 slidably installed inside the box body 1 and clamped with a plurality of pins 73 on one side, and tension springs 76 fixedly installed between the inside of the box body 1 and the push plate 74 at both ends.

[0028] The top sides of the box body 1 are provided with limiting grooves 11 having the same width as the push plate 74. The limiting grooves 11 have the same width as the push plate 74 so that the push plate 74 can slide in the limiting grooves 11.

[0029] A paper slot 31 having the same size as A4 paper is provided on one side of the flip cover 3. The paper slot 31 is used to store A4 paper, and the minimum depth of the paper slot 31 is to be able to store 100 A4 papers.

[0030] The pull rods 6 are hinged in pairs, and when the box body 1 and the publicity board 2 are at 90 degrees, the two pull rods 6 are in a line. This prevents the shelf 7 from rising when the publicity board 2 is turned over, and only when the publicity board 2 is turned over again after 90 degrees, the shelf 7 is raised through the pull rods 6, so as to prevent the shelf 7 from colliding with the publicity board 2.

[0031] The pencil case 71 includes two sides with slide grooves 711 whose height matches that of the pin 73, and a sponge block 712 disposed below the pencil case 71. The slide grooves 711 are used to limit the sliding of the pin 73 in the slide grooves 711, so that the pencil case 71 can be driven to rise when the connecting rod 72 is retracted to one side; and the sponge block 712 moves vertically downward after the pencil case 71 is retracted to fix the drawing pen in the pencil case 71 below.

[0032] The push plate 74 includes a U-shaped groove 741 in the middle, a hinge block 742 on one side, and a connection hole 743 on the hinge block 742; the connection hole 743 is hinged to the bottom of the pull rod 6. One end of the U-shaped groove 741 is open, and the U-shaped groove 741 is used to drive the connecting rod 72 to contract to one side through the pin 73, so that the connecting rod 72 drives the pen case 71 to rise, and the connection between the hinge hole and the pull rod 6 enables the movement of the push plate 74 to be driven by the action of opening the cover.

[0033] Example 2

[0034] The pencil case 71 of the present invention should be able to accommodate 36 color pencils, 36 color oil pastels, 60 color markers, 12 2B pencils, as well as an eraser and a pencil sharpener;

[0035] The publicity board 2 of the utility model is made of transparent material, and publicity papers can be placed inside;

[0036] The depth of the paper slot 31 of the present invention is set to 1 cm;

[0037] The size of the flip cover of the utility model is larger than that of the publicity board.

[0038] Example 3

[0039] Working principle: When the painter uses the utility model, the painter can pull out the writing board 5 from the lower part of the box body 1 as needed, then open the flip cover 3 to take out the A4 paper, and then open the publicity board 2. After the publicity board 2 is flipped to 90 degrees, the two pull rods 6 are in a straight state, and under the continuous flipping of the publicity board 2, the pull rod 6 pulls the push plate 74 to move through the hinge block 742. After the push plate 74 moves, the pin 73 on one side of the connecting rod 72 moves along one side of the slide rail 75 through the U-shaped groove 741. The squeezed two connecting rods 72 shrink and the top rises. At the same time, the pin 73 on one side of the top of the connecting rod 72 slides in the slide groove 711 of the pen box 71, driving multiple pen boxes 71 to rise at the same time;

[0040] After use, the user returns the paintbrush, and then the promotional board 2 and the flip cover 3 are closed. When the promotional board 2 is closed, the pull rod 6 is folded, and at the same time, the tension spring 76 at the bottom of the push plate 74 drives the push plate 74 to return to its original position, so that the push plate 74 drives the connecting rod 72 to expand to the other side of the slide rail 75 through the pin 73, thereby causing multiple pencil boxes 71 to shrink into the box body 1 at the same time, and the sponge block 712 under the pencil box 71 fixes the paintbrush in the pencil box 71.
