New energy energy-saving charging pile for electric vehicle

The new energy energy-saving charging pile for the electric vehicle comprises a charging pile base and a charging pile fixedly installed on the top face of the charging pile base, supporting legs are fixedly connected to the two sides of the charging pile base, a groove is formed in the bottom face of the charging pile base, and a piston cylinder matched with the groove in shape is placed in the groove; when the bolt is rotated, the piston can be pushed to move downwards, at the moment, air in the lower cavity is discharged through the air guide hole, air in the suction cup can be sucked into the upper cavity in the top of the piston through the through hole, the hose and the air channel, and when the piston descends to a certain position, the air in the suction cup is sucked completely. And meanwhile, the hose is gradually bent along with descending of the piston and is finally flattened at the bottom end in the piston cylinder by the piston, at the moment, the hose does not communicate with the through hole
