[0027] An expansion mechanism is installed at the bottom of the first desktop 1, and is used to expand the desktop usage area of ​​the first desktop 1 and the second desktop 2. The expansion mechanism includes a plurality of fixed blocks 12 fixedly connected to the bottom array of the first desktop 1, a second traction plate 18 movably sleeved with the plurality of fixed blocks 12, and an expansion plate 19 fixedly connected to the second traction plate 18. The expansion mechanism also includes a connecting plate 13 fixedly connected to the fixed block 12, the bottom of the connecting plate 13 is symmetrically rotatably connected to two bidirectional threaded rods 14, and both ends of the two bidirectional threaded rods 14 are respectively threadedly sleeved with moving frames 15, and the two moving frames 15 are rotatably connected to the same telescopic fence 16, and the other end of the telescopic fence 16 is rotatably connected to a sliding block 17, and a trapezoidal slider is fixedly connected to the sliding block 17, and a trapezoidal slider is opened at the bottom of the expansion plate 19 corresponding to the trapezoidal slider, and the trapezoidal slider is movably sleeved inside the trapezoidal slider, and a guide slide 25 is symmetrically fixedly connected to one side of the top of the connecting plate 13, and guide grooves are respectively opened at the corresponding guide slides 25 inside the second desktop 2, and the guide slides 25 are respectively movably sleeved inside the guide grooves;

[0028] The driving mechanism is installed inside the first desktop 1 and the second desktop 2, and is used to output power to the expansion mechanism. A linkage mechanism is provided between the driving mechanism and the expansion mechanism. The driving mechanism includes a mounting groove opened on the connecting plate 13, and a driving motor 20 is fixedly connected to the inside of the mounting groove. The output shaft of the driving motor 20 is fixedly connected to the first gear 21.

[0029] In this embodiment, the linkage mechanism includes a double-headed worm gear 22 rotatably connected to the inside of the mounting groove, a second gear 23 is fixedly connected to the double-headed worm gear 22, one side of the second gear 23 is meshingly transmitted with the first gear 21, and a worm wheel 24 is fixedly connected to the bidirectional threaded rod 14, one side of the worm wheel 24 is meshingly transmitted with the double-headed worm gear 22.

[0030] In this embodiment, the push rod motor 10 is fixedly connected to the bottom of the first desktop 1 and the second desktop 2, respectively; a second extension plate 26 is fixedly connected to one side of the first desktop 1; movable grooves are respectively opened on one side of the second desktop 2 corresponding to the second extension plate 26; the second extension plate 26 is movably mounted inside the movable groove; a control panel is fixedly connected to one side of the first desktop 1; the control panel is electrically connected to the push rod motor 10 and the drive motor 20, respectively.

[0031] Working principle: When in use, when height adjustment is required, the power output of the push rod motor 10 is controlled through the control panel. When the push rod motor 10 is started, it drives the first traction plate 11 to move. When the first traction plate 11 moves, it drives the first traction arm 9 to flip and move. The movement and flipping of the first traction arm 9 drives the connecting frame 4 to move. The movement of the connecting frame 4 drives the first extension arm 3 and the second extension arm 5 to swing synchronously. When the first extension arm 3 and the second extension arm 5 swing, the height of the first desktop 1 and the second desktop 2 is adjusted.

[0032] When it is necessary to expand the usable area, the first desktop 1 is pulled outward and stretched. The pulling of the first desktop 1 drives the connecting plate 13 to move synchronously through the fixed block 12, and the connecting plate 13 moves smoothly along the guide slide groove through the guide slide plate 25. When the first desktop 1 and the second desktop 2 are completely separated, the driving motor 20 is controlled to start through the control panel. The start of the driving motor 20 drives the rotation of the first gear 21, and the rotation of the first gear 21 meshes and rotates with the second gear 23, thereby driving the double-headed worm 22 to rotate. The rotation of the double-headed worm 22 meshes and transmits with the worm wheel 24. The rotation of the worm wheel 24 drives the two-way threaded rod 14 to rotate. The rotation of the two-way threaded rod 14 drives the movement of the moving frames 15 at both ends. The movement of the moving frame 15 drives the telescopic fence 16 to extend and contract. The extension of the telescopic fence 16 drives the sliding block 17 to move, and the movement of the sliding block 17 drives the expansion plate 19 to move along the moving groove on the fixed block 12. When the expansion plate 19 is flush with the first desktop 1 and the second desktop 2, the driving motor 20 stops running.

[0033] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
