[0082] When people need to raise the height of the table top 3, they manually turn the hand wheel 72 to rotate the first rotating shaft 71, which causes the bevel gear set 73 to rotate, and then the threaded sleeve 53 and the connecting nut 54 rotate upward at the same time, thereby achieving a rotation effect and reducing the operation of people manually turning the two connecting nuts 54. When the table top 3 moves to a suitable position, people stop turning the hand wheel 72. When people need to lower the height of the table top 3, people manually turn the hand wheel 72 in the opposite direction, thereby causing the first rotating shaft 71 to rotate in the opposite direction, which causes the bevel gear set 73 to rotate in the opposite direction, and then the threaded sleeve 53 and the connecting nut 54 rotate in the opposite direction and move downward at the same time. When the table top 3 moves to a suitable position, people stop turning the hand wheel 72.

[0083] When people need to sit on the seat 65, they move the seat 65 backward, so that the mounting plate 61 moves backward. At this time, the hinge block 84 blocks the block 86, so that the block 86 and the hinge block 84 move backward, and then the first slider 82 moves backward. When the seat 65 moves to a suitable position, people stop moving the seat 65. When people need to move the seat 65 forward, they move the seat 65 forward, so that the mounting plate 61 moves forward, so that the block 86 and the hinge block 84 move forward, and then the first slider 82 moves forward. When the seat 65 moves to a suitable position, people stop moving the seat 65. When people need to move the seat 65 elsewhere, they can manually turn the seat 65. The hinge block 84 causes the torsion spring 85 to twist and deform. When the hinge block 84 does not jam the block 86, people can manually move the seat 65 to another place, and then people release the hinge block 84, so that the torsion spring 85 is reset and drives the hinge block 84 to rotate in the opposite direction to reset. When people need to store the seat 65, people manually rotate the hinge block 84, so that the torsion spring 85 is twisted and deformed. Then people move the seat 65 and move the block 86. When the block 86 moves to the bottom of the hinge block 84, people release the hinge block 84, and the torsion spring 85 is reset and drives the hinge block 84 to rotate in the opposite direction to reset. At this time, the hinge block 84 jams the block 86, thereby achieving the storage effect.

[0084] When people need to put books into the storage frame 4, they manually rotate the second shaft 91 so that the second shaft 91 rolls up the rolling curtain 92 and the second slider 93 moves upward. Then people put the books into the storage frame 4. After the placement is completed, people manually rotate the second shaft 91 in the opposite direction so that the second shaft 91 releases the rolling curtain 92 and the second slider 93 moves downward. When the second slider 93 moves downward and contacts the mounting frame 2, people stop rotating the second shaft 91 in the opposite direction, thereby achieving a shielding effect and preventing dust from falling into the storage frame 4.

[0085] Initially, the connecting block 106 squeezes the third slider 103, the pressure spring 105 is in a stretched state, the first slider 82 moves backwards, driving the connecting block 106 to move backwards. At this time, the pressure of the connecting block 106 on the third slider 103 is relatively small, so that the pressure spring 105 slowly resets and drives the third slider 103 to move backwards. At this time, the pulling force of the pull rope 104 on the second slider 93 is relatively small, so that the torsionally deformed volute spring 107 resets and drives the second rotating shaft 91 to rotate, so that the second rotating shaft 91 rolls up the rolling curtain 92. Later people can sit on the seat 65 and put the books into the storage frame 4. The first slider 82 moves forward to drive the connecting block 106 to move forward. When the connecting block 106 contacts the third slider 103, the connecting block 106 drives the third slider 103 to move forward, so that the pressure spring 105 is stretched. At this time, the pull rope 104 pulls the second slider 93 to move downward, so that the second rotating shaft 91 rotates in the opposite direction to release the rolling curtain 92 to cover the storage frame 4, and then the spiral spring 107 twists and deforms, thereby achieving the effect of automatic covering.

A volute spring (107), wherein volute springs (107) are connected between the left and right sides of the second rotating shaft (91) and the table top (3), and the volute springs (107) are wound around the second rotating shaft (91); Initially, the connecting block (106) squeezes the third slider (103), the pressure spring (105) is in a stretched state, the first slider (82) moves backwards, driving the connecting block (106) to move backwards. At this time, the pressure of the connecting block (106) on the third slider (103) is relatively small, so that the pressure spring (105) slowly resets and drives the third slider (103) to move backwards. At this time, the pulling force of the pull rope (104) on the second slider (93) is relatively small, so that the torsionally deformed spiral spring (107) resets and drives the second rotating shaft (91) to rotate, so that the second rotating shaft (91) rolls up the rolling curtain (92). People can sit on the seat (65) and put books into the storage frame (4). The first slider (82) moves forward to drive the connecting block (106) to move forward. When the connecting block (106) contacts the third slider (103), the connecting block (106) drives the third slider (103) to move forward, thereby stretching the pressure spring (105). At this time, the pull rope (104) pulls the second slider (93) downward, causing the second rotating shaft (91) to rotate in the opposite direction to release the rolling curtain (92) to cover the storage frame (4), and then the spiral spring (107) is twisted and deformed, thereby achieving an automatic covering effect. The hinge block (84) is used to lock a clamping block (86) provided on the mounting plate (61) in the support mechanism (6). When people need to sit on the seat (65), they move the seat (65) backward, thereby causing the mounting plate (61) to move backward, the clamping block (86) and the hinge block (84) to move backward, and then the first slider (82) to move backward. When people need to move the seat (65) forward, they move the seat (65) forward, thereby causing the mounting plate (61) to move forward, the clamping block (86) and the hinge block (84) to move forward, and then the first slider (82) to move forward.
