The user can use a tool to rotate the adjusting screw 50 with the internal hexagonal hole, which is convenient for the user to use.

[0049] The specific adjustment process of this utility model is as follows: For example, when the adjusting screw 50 is rotated in the forward direction, since the adjusting screw 50 is threadedly engaged with the rear body 403, and the rear body 403 is constrained by the rear support upper arm 401 and the rear support lower arm 402 and cannot rotate synchronously with the adjusting screw 50, the rear body 403 moves in direction A along the axial direction of the adjusting screw 50. At this time, the rear support upper arm 401 rotates counterclockwise around the corresponding pivot 70, and the rear support lower arm 402 rotates clockwise around the corresponding pivot 70. Through the meshing of the rear upper toothed part 405 and the front upper toothed part 305, the rear support upper arm 401 drives the front support upper arm 301 to rotate clockwise around the corresponding pivot 70. Through the meshing of the rear lower toothed part 406 and the front lower toothed part 306, the rear support lower arm 402 drives the front support lower arm 302 to rotate counterclockwise around the corresponding pivot 70, thereby driving the front support unit 30 to move in direction B along the axial direction of the adjusting screw 50, so that the top plate 10 rises.

At this time, the rear support upper arm 401 rotates clockwise around the corresponding pivot 70, and the rear support lower arm 402 rotates counterclockwise around the corresponding pivot 70. Through the meshing of the rear upper toothed part 405 and the front upper toothed part 305, the rear support upper arm 401 drives the front support upper arm 301 to rotate counterclockwise around the corresponding pivot 70. Through the meshing of the rear lower toothed part 406 and the front lower toothed part 306, the rear support lower arm 402 drives the front support lower arm 302 to rotate clockwise around the corresponding pivot 70, thereby driving the front support unit 30 to move in direction A along the axial direction of the adjusting screw 50, so that the top plate 10 descends.
