An inverted cone airfoil type backward stacking single-head electrical connection device, characterized in that The electrical connection device comprises a portion A of an inverted cone-shaped backward-nested single-head electrical connection device provided with a metal inverted cone-shaped wing body A having at least one inverted cone-shaped convex wing, at least one positioning auxiliary part A, and at least one rebound-type telescopic mechanism, and a portion B of an inverted cone-shaped backward-nested single-head electrical connection device provided with a metal inverted cone-shaped wing body B and at least one positioning auxiliary part B. The metal inverted cone-shaped backward-nested single-head electrical connection device A portion is provided with an inverted cone-shaped convex wing which corresponds to and matches the positioning guide groove on the metal inverted cone-shaped wing body B of the inverted cone-shaped backward-nested single-head electrical connection device B portion and can guide its rotation and accurately guide the positioning. The metal inverted cone-shaped wing body A is provided with a positioning guide groove which corresponds to the metal inverted cone-shaped wing body B of the inverted cone-shaped backward-nested single-head electrical connection device B portion. The inverted cone wing electric contact surface B arranged in a corresponding manner on the main body B corresponds to the matching inverted cone wing electric contact surface A. The number, relative positions and positions of the inverted cone wing electric contact surfaces A relative to the central axis of the metal inverted cone wing main body A are consistent and matched with the number, relative positions and positions of the inverted cone wing electric contact surfaces B on the metal inverted cone wing main body B relative to the central axis of the metal inverted cone wing main body B. The inverted cone wing electric contact surface A on the A part of the inverted cone wing type backward stacking type single-head electrical connection device and the inverted cone wing electric contact surface B on the B part of the inverted cone wing type backward stacking type single-head electrical connection device are connected and conducted by overlapping and wedging with each other through the action of the rebound force of the rebound telescopic mechanism arranged between the metal inverted cone wing main body A and the metal inverted cone wing main body B.

2. The inverted cone airfoil-shaped backward stacked single-end electrical connection device according to claim 1, characterized in that The resilient telescopic mechanism of the electric connection device is composed of a compression spring, a positioning guide sliding spacer sleeve plate, and a positioning guide ring sleeve column.
