[0030] The coupling assembly 2 includes a push rod 21, which is convenient for adjusting the height of the table 13, so as to support items of different specifications. The connecting assembly 3 includes a hinge A31, which is installed at both ends of the push rod 21 by screws 39, so that the push rod 21 can be rotated as needed. The hinge A31 is provided with a mounting groove C32, and a bearing A33 is installed in the mounting groove C32, so that the central axis A34 can be rotated as needed to ensure that the entire device can support the operation normally. The inner surface of the bearing A33 is installed with the central axis A34, which connects the hinge A31 and the hinge B35. They are connected together so that they can work normally. A hinge B35 is provided on the outer surface of the central axis A34, which connects the base 11, the table 13 and the push rod 21 together to assemble them into a complete slide device. The hinge B35 is installed on the central axis A34 by a screw 39. A mounting groove D36 is provided on the hinge B35.
