1. A retractable test probe comprising:
- a main sleeve;
a needle rooted in the main sleeve; and
a conductive sleeve put around a conduction portion of the needle within the main sleeve to electrically connect with the needle;
a copper tube assembly including a first copper tube and a second copper tube, which are longitudinally connected to each other, the conductive sleeve being received in the second copper tube and sandwiched between the first copper tube and the second copper tubea rotation positioning mechanism, comprising an eccentric incoaxially fastened to the needle and a flexible sleeve around the eccentric and in the main sleeve;
wherein when the needle is turned towards a specific direction, the eccentric will be firmly fastened in the main sleeve through the flexible sleeve, when the needle is turned reversely, the eccentric will be released from the flexible sleeve to be retractably movable,wherein the conductive sleeve has a conductive elastic sheet nipped between the conduction portion and the conductive sleeve.
