[0018] One end of the two connecting seats 4 is fixed on the other end of the two rotating shafts 1 respectively, specifically, key connection is adopted, and the rotating shaft 1 can drive the connecting seat 4 to rotate. The other end of the two connecting seats 4 is connected with the two ends of the bottom plate 5, under the action of natural gravity, the bottom plate 5 is in a horizontal state, in addition, the installation of the first rotating shaft seat 2 and the second rotating shaft seat 3 should also have a certain height, so that there is enough space for the bottom plate 5 to rotate around the axis line of the rotating shaft 1.

[0019] The fixed disc 6 is fixed outside the first rotating shaft base 2, and the fixed disc 6 is provided with a through hole corresponding to the position of the rotating shaft 1, and the disc surface of the fixed disc 6 is provided with a clamping groove 6a. The driving rod 7 is fixed at one end of the rotating shaft 1 through the through hole and can rotate with the rotating shaft 1. In other embodiments, the one end of the rotating shaft 1 can be extended and passed through the through hole of the fixed disc 6 to form the driving rod 7, and the driving rod 7 and the rotating shaft 1 are integrated to reduce the installation steps and increase the torsional strength.

[0020] The handle 8 is hinged with the driving rod 7, and the handle 8 has a part that can be clamped in the clamping groove 6a. In the embodiment, the bottom end of the handle 8 is Y-shaped, the bottom end of the handle 8 forks the driving rod 7 and is hinged with the driving rod 7, and the top end of the handle 8 is provided with a ball head for easy operation.
