A secondary magnet (a2) that can form a magnetic attraction fit with the main magnet (612) is fixedly provided in the limiting groove (a1). The left sound-absorbing plate (2), the right sound-absorbing plate (3) and the rear sound-absorbing plate (4) are fixed on the side of the desktop plate (1) by the elastic force of the reset spring (62), the plug-in limit fit between the limiting groove (a1) and the limiting block (61) on the mounting frame (a) and the magnetic attraction fit between the main magnet (612) and the secondary magnet (a2).

4. The multifunctional sound-absorbing and height-adjustable table according to claim 3, characterized in that: The limiting block (61) has a guide slope (611) on the side facing outward, which can guide the limiting block (61) and the limiting groove (a1) to form a limiting fit during the sliding of the corresponding mounting frame (a). The lower end of the guide slope (611) extends towards the desktop (1), and the upper end of the guide slope (611) extends outward. There is a mounting groove between the upper end of the guide slope (611) and the surface of the limiting block (61) facing the limiting groove (a1) for the main magnet (612) to be installed. The main magnet (612) is fixedly installed in the mounting groove and flush with the opening of the mounting groove.

5. A multifunctional sound-absorbing and height-adjustable table according to claim 1, characterized in that: The positioning component includes a first magnetic block (51), a second magnetic block (52), a third magnetic block (53), and a fourth magnetic block (54). The first magnetic block (51), the second magnetic block (52), the third magnetic block (53), and the fourth magnetic block (54) can all form a magnetic attraction with each other. The mounting frames (a) of the left sound-absorbing plate (2) and the right sound-absorbing plate (3) are both fixedly provided with the first magnetic block (51) on the side facing the lower end of the desktop plate (1) after rotation. The lower end of the desktop plate (1) is fixedly provided with a second magnetic block (52) that corresponds one-to-one with the first magnetic block (51). The left sound-absorbing plate (2) and the right sound-absorbing plate (3) are connected by a magnetic attraction when rotated. The first magnetic block (51) and the second magnetic block (52) are magnetically attached to the lower end of the desktop panel (1). The mounting frames (a) of the left sound-absorbing plate (2) and the right sound-absorbing plate (3) are both fixed with the third magnetic block (53) on the side facing away from the lower end of the desktop panel (1) after rotation. The mounting frames (a) of the rear sound-absorbing plate (4) are both fixed with the fourth magnetic block (54) on the side facing the left sound-absorbing plate (2) and the right sound-absorbing plate (3) after rotation. The rear sound-absorbing plate (4) is fixed to the left sound-absorbing plate (2) and the right sound-absorbing plate (3) of the desktop panel (1) after rotation through the magnetic attachment of the third magnetic block (53) and the fourth magnetic block (54).

6. The multifunctional sound-absorbing and height-adjustable table according to claim 1, characterized in that: The lower end of the desktop panel (1) is still fixedly provided with lifting table legs (c). There are four lifting table legs (c). The four lifting table legs (c) are respectively fixedly installed on the first mounting block (11) on the left side of the desktop panel (1) and on the second mounting block (12) on the right side of the desktop panel (1).
