The bottom of the conductive column penetrates the base. A first guide part is arranged on the base. A second guide part is arranged on the conductive column. At least one of the first guide part and the second guide part extends in the shape of spiral from bottom to top. The bottom of the conductive column is provided with a scraper. In the present application, the scraper at the bottom of the conductive column is used to clean crystals on a conductive piece, which ensures good contact and improves the stability of a current and voltage during an electroplating process. ## Claims ### Claim 1 An electroplating conductive fixture, comprising: a base, a top cover cooperating with the base, an accommodating cavity provided between the base and the top cover, and a lifting-type conductive column accommodated in the accommodating cavity, wherein a bottom end of the conductive column runs downward through the base and extends out of the accommodating cavity; the base is provided with a first guide part, and the conductive column is provided with a second guide part which cooperates with the first guide part, wherein at least one of the first guide part and the second guide part extends in a bottom-up spiral shape; and a scraper is provided at the bottom end of the conductive column; and the bottom end of the conductive column, when acted by an external force, moves towards the accommodating cavity; and the conductive column rotates in the movement process under an interaction between the first guide part and the second guide part, and moves so as to be restored after the external force is withdrawn. ### Claim 2 (depends on 1) The electroplating conductive fixture according to claim 1, wherein the accommodating cavity comprises an upper cavity body and a lower cavity body that are formed on the base, and the first guide part is formed on an inner wall surface of the lower cavity body and protrudes into the lower cavity body. ### Claim 3 (depends on 2) The electroplating conductive fixture according to claim 2, wherein the lower cavity body runs downward through a bottom surface of the base and forms a lower opening in the bottom surface; and the first guide part is a protruding rib extending in a spiral shape and extends from top to bottom to a position of the lower opening. ### Claim 4 (depends on 3) The electroplating conductive fixture according to claim 3, wherein the conductive column is provided with an upper cylinder body accommodated in the upper cavity body and a lower cylinder body accommodated in the lower cavity body; and the second guide part is a groove that extends in a spiral shape, and is formed on a circumferential surface of the lower cylinder body and extends from top to bottom. ### Claim 5 (depends on 2) The electroplating conductive fixture according to claim 2, wherein the conductive column is provided with an upper cylinder body, a lower cylinder body, an abutment seat connected between the upper cylinder body and the lower cylinder body, and a spring sleeving the upper cylinder body; and an annular supporting portion is formed at the bottom of the upper cavity body; the supporting portion supports the abutment seat upwards, and the abutment seat supports the spring upward. ### Claim 6 (depends on 5) The electroplating conductive fixture according to claim 5, wherein the conductive column further comprises a retractable guide rod accommodated in the upper cylinder body and the lower cylinder body, and an elastic member sleeves the retractable guide rod and is accommodated in the lower cylinder body. ### Claim 7 (depends on 6) The electroplating conductive fixture according to claim 6, wherein an accommodating groove and a through hole are also formed inside the lower cylinder body; the elastic member is accommodated in the accommodating groove, the through hole extends downward and penetrates to an end surface of the bottom of the conductive column; a bottom end of the retractable guide rod is accommodated in the through hole; and a top end of the retractable guide rod extends upward and protrudes to a top surface of the upper cylinder body. ### Claim 8 (depends on 1) The electroplating conductive fixture according to claim 1, wherein the scraper comprises three scraping strips, and the three scraping strips are formed as a trident star in shape; and a width of each scraping strip gradually decreases in a radial direction from inside to outside. ### Claim 9 (depends on 1) The electroplating conductive fixture according to claim 1, wherein the bottom end of the conductive column is provided with a circular bottom surface, and the scraper extends in a straight line and runs through a center of the circular bottom surface. ### Claim 10 An electroplating conductive fixture, comprising a base and a lifting-type conductive column mounted within the base, wherein the conductive column and the base cooperate with each other via a guide portion having a spiral shape, such that the conductive column rotates while being lifted; and a bottom end of the conductive column is provided with a scraper exposed below the base.
