The placement platform 7 is used to place a notebook, but the notebook is easily shaken and dropped, so the notebook is limited by setting the elastic member 9.

[0025] The elastic member 9 is composed of a clamping section 11 and an inclined section 12, a vertical section 13, a horizontal section 14 and an arc section 15 arranged on both sides of the clamping section 11, and a positioning opening 16 is formed in the middle of the arc section 15. The clamping section 11 is in contact with the placement platform 7, and the inclined section 12 keeps the clamping section 11 on the placement platform 7, so that the clamping section 11 is forcefully arranged on the placement platform 7, which is convenient for clamping the notebook.

[0026] The positioning assembly 3 is installed on the moving seat 1, and is provided with a positioning seat 17, a positioning member 18 and a retaining member 19. The positioning seat 17 is installed on the moving seat 1, and a sliding area 20 is provided on the positioning seat 17. T-shaped grooves 21 are provided on both sides of the sliding area 20. T-shaped blocks 22 that cooperate with the T-shaped grooves 21 are provided on both sides of the positioning member 18, and the positioning member 18 is arranged in the middle of the positioning seat 17.

[0027] The positioning member 18 is provided with symmetrically arranged positioning blocks 23, and a positioning area 24 is formed between the positioning blocks 23. The middle of the retaining member 19 is installed in the sliding area 20 through a rotating shaft 25, and the rotating shaft 25 is located in the middle of the retaining sleeve 40. The two ends of the retaining member 19 are connected to the positioning member 18 through the retaining blocks 26. The positioning member 18 is also provided with a pushing portion 27, and the pushing portion 27 is used to push the positioning member 18 or pull the positioning member 18 to deform the retaining member 19. An active area 28 is formed between the pushing portion 27 and the positioning block 23, and the active area 28 is connected to the positioning area 24, and the width of the active area 28 is greater than the width of the positioning area 24.

[0028] Symmetrical fixing holes 29 are provided in the sliding area 20 . A blocking rod 30 is provided in the fixing hole 29 . The blocking rod 30 contacts the positioning block 23 .

[0029] A storage hopper 2 is provided on the positioning assembly 3, a storage chamber 31 is formed in the middle of the storage hopper 2, a discharge pipe 6 is provided at the lower end of the storage hopper 2, a fixed block 32 is provided on the discharge pipe 6, a baffle 33 is provided on the fixed block 32, a rotating rod 34 is provided at the lower end of the storage hopper 2, a rotating hole 35 for accommodating the rotating rod 34 is provided on the sliding area 20, and the rotating rod 34 is arranged in the positioning area 24 and limited by the positioning block 23.

[0030] The rotating rod 34 is composed of a connecting section 36 and a rotating section 37. A positioning notch 38 is provided between the connecting section 36 and the rotating section 37.
