Claim:
1. A miniaturization rechargeable capacitive stylus, comprising: a pen-shaped casing structure having a retaining convex portion disposed on a top side thereof; a support structure disposed inside the pen-shaped casing structure; a circuit substrate positioned on the support structure and disposed inside the pen-shaped casing structure; a sensor module positioned on the support structure and disposed inside the pen-shaped 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 casing structure; an electrical connector structure positioned on the support structure and disposed inside the pen-shaped 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 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 pen-shaped casing structure is inserted into a receiving space of a portable electronic device, the pen-shaped casing structure is positioned inside the receiving space of the portable electronic device by matching the retaining convex portion of the pen-shaped casing structure and a retaining concave portion that is disposed inside the receiving space of the portable electronic device; wherein the support structure includes a first support element for supporting the circuit substrate, the sensor module, the pen head structure, and the power supply component, and a second support element separated from the first support element by a predetermined distance for supporting the electrical connector structure, and the first support element includes a first support body and a second support body mated with the first support body.
