[0025] Working principle: When the size of the desktop of the conference table needs to be adjusted, the servo motor 91 can be started through an external controller to drive the worm 92 to rotate, and then the worm gear 93 can be used to drive the first threaded rod 3 to rotate. During the rotation of the first threaded rod 3, the two moving blocks 4 and the two first table boards 5 will be driven to move in opposite directions until they move to the limit distance. Then the dual-axis servo motor 181 can be started to drive the two driving bevel gears 182 to rotate, and then the two threaded sleeves 16 will be driven to rotate through the two driven bevel gears 183. During the rotation of the two threaded sleeves 16, the two second threaded rods 17 will be driven to move upward, and then the second table board 12 will be driven upward, so that the second table board 12 moves to the middle of the two first table boards 5. At this time, the two limit The tops of the blocks 15 are all in contact with the inner top walls of the U-shaped frame 10, and the servo motor 91 is then started to rotate it in the opposite direction, thereby driving the first threaded rod 3 to rotate in the opposite direction. At this time, the first threaded rod 3 will drive the two moving blocks 4 and the two first table boards 5 to move relative to each other during rotation, so that the first connecting block 8 is inserted into the interior of the second connecting groove 13, and the second connecting block 14 is inserted into the interior of the first connecting groove 7, until the opposite sides of the two first table boards 5 are tightly fitted with the left and right sides of the second table board 12, respectively, so that the two first table boards 5 and the second table boards 12 are pieced together to form a complete large table board, thereby expanding the size of the desktop of the conference table, and finally achieving the purpose of adjusting the size of the desktop, thereby improving the practicality of the conference table and facilitating the use of users.

[0026] In summary, the conference table with desktop adjustment function drives the worm 92 to rotate by starting the servo motor 91, and then drives the first threaded rod 3 to rotate through the worm gear 93. During the rotation of the first threaded rod 3, the two moving blocks 4 and the two first table boards 5 are driven to move in opposite directions until they move to the limit distance. Then, the dual-axis servo motor 181 is started to drive the two driving bevel gears 182 to rotate, and then the two threaded sleeves 16 are driven to rotate through the two driven bevel gears 183. During the rotation of the two threaded sleeves 16, the two second threaded rods 17 are driven to move upward, and then the second table board 12 is driven to move upward, so that the second table board 12 moves to the middle of the two first table boards 5, and then the servo motor 181 is started. The servo motor 91 makes it rotate in the opposite direction, thereby driving the first threaded rod 3 to rotate in the opposite direction. At this time, the first threaded rod 3 will drive the two moving blocks 4 and the two first table boards 5 to move relative to each other during the rotation, until the opposite sides of the two first table boards 5 are tightly fitted with the left and right sides of the second table board 12 respectively, thereby piecing together the two first table boards 5 and the second table boards 12 to form a complete large table board, thereby expanding the size of the desktop of the conference table, and finally achieving the purpose of adjusting the size of the desktop, thereby improving the practicality of the conference table, facilitating the use of users, and solving the problem that the size of ordinary conference tables is mostly fixed, and most of them do not have the function of adjusting the size of the desktop of the conference table, so they have certain limitations when used.
