The invention discloses a novel new energy electric vehicle charging device which comprises a charging part arranged in a charging pile and a charging gun matched with the charging part. The charginggun slot is arranged on the bottom end face of the charging part. First sliding grooves extending to the outside are arranged in the left and right sides of the charging gun slot. The outer head sideward wall of the first sliding groove is provided with a second sliding groove which is communicated with the first sliding groove. A screw rod through groove is formed between the first sliding grooveand the top of the second sliding groove. The charging gun is locked firmly and it is safe and stable. When the charging gun is inserted, the charging gun is locked before it is electrified. When thecharging gun is pulled out, the charging gun is powered off before unlocked. The whole device is convenient to operate. The locking stability of the charging gun is increased. The plug-in and the pulling-out efficiency of the charging gun are greatly increased. An electric shock accident occurring when the charging gun is inserted and pulled out is avoided.
