Claim:
1. A miniaturization rechargeable capacitive stylus, comprising: a pen-shaped metal casing structure having a retaining convex portion disposed on a top side thereof; a support structure disposed inside the pen-shaped metal casing structure; a circuit substrate positioned on the support structure and disposed inside the pen-shaped metal casing structure; a sensor module positioned on the support structure and disposed inside the pen-shaped metal casing structure, wherein the sensor module is electrically connected to the circuit substrate; a pen head structure movably disposed on the support structure to selectively contact the sensor module, wherein the pen head structure has an exposed contact portion exposed from the pen-shaped metal casing structure; an electrical connector structure positioned on the support structure and disposed inside the pen-shaped metal casing structure, wherein the electrical connector structure includes a carrier substrate positioned on the support structure and an electrical connector disposed on the carrier substrate and electrically connected to the carrier substrate, and the electrical connector has an electrical connection portion exposed from the pen-shaped metal casing structure; and a power supply component disposed on the support structure and electrically connected between the circuit substrate and electrical connector structure; wherein the electrical connector includes two single needle spring connectors, each single needle spring connector includes a fixed casing fixed on the carrier substrate, a compression spring disposed inside the fixed casing, and a movable element abutting against the compression spring, one part of the movable element is disposed inside the fixed casing to abut against the compression spring, and the other part of the movable element is exposed from the pen-shaped metal casing structure.
