In this embodiment, in the initial state, the conductive slider 35 is located between the two electric connecting pieces 36, and after the electromagnet 44 is turned on to control the switch, the electromagnet 44 is in the energized state;

when the motor 5 is started, the sliding block 12 contacts two conductive blocks 33 (i.e. moves downwards to a position where the bearing is completely immersed in the oil), at this time, the conductive spring 40 is energized, after the conductive spring 40 is energized, an opposite magnetic field is formed between every two adjacent turns of spring coils, so that the conductive spring 40 contracts integrally, the piston plate 39 is driven to move downwards instantly, gas in the bottom space of the vertical cavity 34 is sucked into the top space of the trigger box 38 instantly, at this time, because the diameter of the thin tube 43 is small, when a large amount of gas is sucked out instantly by the one-way air inlet tube 42, the thin tube 43 cannot supplement gas from the outside in time, so that the air pressure in the bottom space of the vertical cavity 34 becomes low instantly, the conductive sliding block 35 moves downwards instantly, and is separated from contact with the two electrical contact pieces 36, and at this time, the circuit where the electromagnet 44 is located is disconnected;

the rotation of motor 5 can't drive second dwang 10 and rotate, the screen frame 19 can take the bearing to rotate in fluid and soak oil in this period of time, receive the elastic action of recovery spring 37, electrically conductive slider 35 can constantly shift up (but because the setting of tubule 43, the speed of supplementing gas from the external world is slower, the speed that shown electrically conductive slider 35 shifted up is slower), after moving to two contact electricity pieces 36 on, electro-magnet 44 circular telegram, the rotation of motor 5 can drive second dwang 10 once more and rotate, make the continuous shift up of screen frame 19, it can to close electro-magnet 44 and motor 5 when the initial state that shifts up, only need start and close electro-magnet 44 once in the whole process can, make operating personnel operation more convenient.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
