In this way, when the moving platform 2 moves from the second position to the third position, the rod body 41 is stuck in the notch 31. Since the inner wall of the notch 31 is located on the moving path of the rod body 41 to return to the initial position, the driving rod 42 keeps the rod body 41 in the notch 31 under the action of gravity; since when the moving platform 2 moves from the second position to the third position, the sum of the first distance D1 and the second distance D2 is greater than the third distance D3, the first horizontal axis, the rod body 41 and the shaft body 52 can maintain a triangular shape; the swing arm 3 can be rotated from the down position to the upright position during the angle adjustment process; during the process of the swing arm 3 rotating from the down position to the upright position, the power of the swing arm 3 comes from the kinetic energy of the moving platform 2, and the reliability is high.

[0059] For further information, see Figures 1 to 7 As a specific embodiment of the automatic lifting device provided by the utility model, the inner wall of the notch 31 is parallel to the axis of the rod body 41.
