Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-3 A height-adjustable modular student desk and chair includes a desk board 1 and a chair board 2. Both ends of the desk board 1 and the chair board 2 are supported by height-adjustable support legs. A table drawer is provided between the desk board 1 and the height-adjustable support legs. The height-adjustable support legs are composed of interlocking movable rods 3 and T-shaped support rods 4. The table drawer is composed of an interlocking upper drawer 10 and a lower drawer 11. Specifically, connecting sleeves 101 are fixed on both sides of the upper drawer 10 and are fixedly fitted on the outer wall of the movable rod 3. Connecting sleeves 111 are fixed on both sides of the lower drawer 11 and are fixedly fitted on the outer wall of the support rod 4. When the height-adjustable support legs are raised and lowered, the size of the internal space of the table drawer is adjusted to accommodate more books.

[0028] For further details, please refer to Figure 3-4A sliding plate 12 is slidably installed inside the lower compartment 11. Several protruding rails 112 are provided on the inner bottom surface of the lower compartment 11, and several sliding grooves 122 that match the protruding rails 112 are provided on the lower surface of the sliding plate 12. When the sliding plate 12 is pulled out from the lower compartment 11, the protruding rails 112 slide in the sliding grooves 122. Specifically, the protruding rails 112 and the sliding grooves 122 are designed in a T-shape. Books are placed on the sliding plate 12 so that the drawer can be pulled out to find the books. At the same time, the T-shape structure can prevent the tail of the sliding plate 12 from lifting up when the drawer is pulled out.

[0029] For details, please refer to Figure 4 To facilitate the use of the slide 12, the front end of the slide 12 is bent downward to form a protrusion 121, and the lower surface of the protrusion 121 is lower than the lower surface of the lower compartment 11, so that the protrusion 121 can be pried from the lower surface of the lower compartment 11 and the slide 12 can be pulled open. In addition, a magnetic block 123 is embedded in the inner wall of the protrusion 121 so that when the slide 12 is completely slid into the lower compartment 11, the magnetic block 123 can be magnetically attracted and attached to the front end of the lower compartment 11 to maintain the stability of the slide 12 in the compartment.

[0030] Please see Figure 2 and Figure 5 To facilitate adjustment of the height of the lifting support legs, a worm gear 7 is rotatably installed inside the support rod 4. The worm gear 7 is horizontally mounted, and a handle 5 is provided on the outer side of the support rod 4, coaxially connected to one end of the worm gear 7. A connecting rod 6 is also provided between the two support rods 4, coaxially connected to the other end of the worm gear 7, so that the worm gear 7 of the two support legs can rotate synchronously and be connected to the same hand crank handle 5. The middle edge of the worm gear 7 is engaged with a worm wheel 8, and a screw 9 is threaded through and threaded inside the worm wheel 8. The top end of the screw 9 is fixed to the top of the movable rod 3. Specifically, the bottom end of the worm wheel 8 is rotatably connected to a partition plate 81, which is fixed to the inner wall of the support rod 4. The screw 9 passes through the upper and lower surfaces of the partition plate 81, so that when the worm gear 7 drives the worm wheel 8 to rotate, a threaded action occurs between the worm gear 7 and the screw 9. Since the rotation of the screw 9 is restricted by the movable rod 3, it moves up or down relative to the worm wheel 8, thereby controlling the lifting and lowering of the movable rod 3 relative to the support rod 4.

[0031] Please see Figure 1 A storage compartment 13 is also provided between the chair board 2 and the lifting support leg. The opening of the storage compartment 13 faces the desk to further increase storage space.
