The rotating handle 7 is rotatably connected to the rotating shaft 8 at the "U"-shaped open end surface. The rotating shaft 8 is rotatably connected to the threaded tube 9. The inner wall of the threaded tube 9 is threadedly connected to the upper end of the threaded groove surface of the limiting rod 2. The bottom of the threaded tube 9 abuts against the top surface of the pressure plate 5. The other side surface of the bottom shell 3 abuts against the limiting frame 10. The limiting frame 10 is provided with a fixing block 11 near the end surface of the bottom shell 3. The fixing block 11 is engaged with the "L"-shaped longitudinal end surface of the bottom shell 3. The inner wall of the limiting frame 10 is sleeved on the surface of the draft paper body 1.

[0023] Preferably, two sets of circular through grooves are opened on one side surface of the draft paper body 1, and the shape and size of the through grooves are adapted to the limiting rod 2.

[0024] In practical use, when using the draft paper body 1, the limiting rod 2 provided on the bottom shell 3 passes through the circular through groove provided on the surface of the draft paper body 1, thereby adjusting and fixing the position of the draft paper body 1 on the bottom shell 3.

[0025] Preferably, a circular limiting groove 4 is longitudinally opened on the inner wall surface of the "U"-shaped end of the bottom shell 3, and the shape and size of the limiting groove 4 are adapted to the protrusions on both sides of the pressure plate 5, and a semi-circular rubber strip is provided at the bottom of the pressure plate 5.

[0026] In practical use, after placing a stack of draft paper body 1, the pressure plate 5 is slidably connected to the limiting groove 4 opened on the inner wall of the draft paper body 1, so that the pressure plate 5 presses on the header of the draft paper body 1 to fix it.

[0027] Preferably, the limiting rod 2, the pressure plate 5, and the threaded tube 9 form a threaded connection structure.

[0028] In practical use, the threaded tube 9 is threaded onto the top of the limiting rod 2, and the rotating shaft 8 connected to both sides of the threaded tube 9 is used to rotate the rotating handle 7 connected to both sides upwards and vertically to the top of the limiting rod 2.

[0029] Preferably, the handle 7 is a Y-shaped integrated structure, and the shape and size of the open end of the handle 7 are adapted to the threaded tube 9.

[0030] In practical use, the connection between the open end of the handle 7 and the rotating shaft 8 is fixed by abutting against each other.

[0031] Preferably, the limiting frame 10 is a U-shaped integrated structure, and two sets of fixing blocks 11 are located on the longitudinal end surface of the limiting frame 10. The fixing blocks 11 are rectangular blocks with rubber strips on both sides in the longitudinal direction, and the shape and size of the fixing blocks 11 are adapted to the through groove on the longitudinal end surface of the bottom shell 3 on the "L" side.

[0032] In practical use, the limiting frame 10 slides from the header to the foot of the draft paper body 1, and the fixing block 11 on the other side of the limiting frame 10 engages with the longitudinal end of the bottom shell 3 to compact the surface of the foot of the draft paper body 1.

[0033] Working principle: When using the draft paper body 1, the limiting rod 2 on the bottom shell 3 passes through the circular groove on the surface of the draft paper body 1, thereby fixing the position of the draft paper body 1 on the bottom shell 3. After placing a stack of draft paper bodies 1, the pressure plate 5 slides onto the limiting groove 4 on the inner wall of the draft paper body 1, thus pressing the pressure plate 5 against the header of the draft paper body 1 to fix it. Additionally, a threaded tube 9 is threaded onto the top of the limiting rod 2, and the rotating shafts 8 connected to both sides of the threaded tube 9 rotate the rotating handles 7 connected to both sides upwards to a vertical position on the top of the limiting rod 2, thereby gripping the rotating handles 7. The threaded tube 9 rotates on the limiting rod 2, allowing it to press down on the pressure plate 5 to make it tightly abut against the top of the draft paper body 1. After adjusting the position of the threaded tube 9, the rotating shaft 8 on its surface is placed horizontally, and the rotating handle 7 is rotated again so that its horizontal end is engaged with the limiting block 6, thereby fixing the position of the rotating handle 7. Then, the limiting frame 10 slides from the header to the foot of the draft paper body 1, and the fixing block 11 on the other side of the limiting frame 10 is engaged with the longitudinal end of the bottom shell 3 to press the foot surface of the draft paper body 1 firmly, preventing the draft paper body 1 from curling due to the arm rubbing back and forth on the foot during use, which would affect the neatness and aesthetics of the draft paper body 1.
