Improved structure of take-up pulley

The utility model discloses an improved structure of take-up pulley, comprising a take-up pulley body whose two sides are provided with a first container and a second container which are connected with each other. A first wheel disc and a second wheel disc are combined respectively with the first container and the second container, a first elongation line is rolled on the first wheel disc, one end of the first elongation line is connected with the power switch of the first wheel disc and the conducting strip of the power source socket in conductivity, and another end of the first elongation line is a power plug which is exposed outward the bottom edge of the rear side of the take-up pulley body. A second elongation line is rolled on the second wheel disc, one end of the second elongation line is connected with the first elongation line in conductivity, and another end of the second elongation line is connected with an energy consumption product, which is exposed outward the bottom edge of the front side of the take-up pulley body. The first wheel disc and the second wheel disc work independently, without connection, so the first elongation line and the second elongation line are not connected. When the power source enters the power source socket through the power source socket of the first elongation line, the power source is transmitted to the electricity consumption product through the second elongation line, the electricity consumption product works, and the power source socket with power source on the first wheel disc is used for the user.
