The lower end of the connecting rod 3 is provided with a buoy 4 floating on the water surface, and the buoy 4 rises or falls along with the liquid level of the water level, so that the connecting rod 3 is driven to move up or down. The upper end of the connecting rod 3 is provided with a push rod 5 vertically connected with the connecting rod, and the lengths of the push rod 5, which are extended from the left end to the right end by taking the connecting rod 3 as a midpoint, are symmetrically equal. The cover 2 positioned on two sides of the connecting hole is respectively provided with a control plate 6 and a limiting plate 7 which are symmetrically arranged, and two ends of the push rod 5 are respectively movably sleeved on the control plate 6 and the limiting plate 7. The upper part and the lower part of the control panel 6 are respectively provided with an upper button switch 8 and a lower button switch 9, and the pressing directions of the upper button switch 8 and the lower button switch 9 are respectively aligned with the upper surface and the lower surface of the push rod 5. In addition, go up button switch 8 and button switch 9 down and all adopt normally open contact, when pressing the button promptly, normally open contact is closed, and series circuit intercommunication is electrically conductive, loosens the button, resumes original operating condition under the reset spring's of self effect, above for prior art's conventional means, no longer gives unnecessary details here. A T-shaped fixture block 10 is arranged at one end, connected with the limiting plate 7, of the push rod 5, a sliding groove 11 matched with the fixture block 10 is arranged on the side, facing the push rod 5, of the limiting plate 7, an upper spring 12 and a lower spring 13 are arranged at the upper end and the lower end of the limiting plate 7 respectively, and the upper spring 12 and the lower spring 13 are arranged right opposite to the upper side and the lower side of the push rod 5 respectively.
