[0014] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0015] 1. This solution limits the positions of multiple cable bodies to be wrapped between the circular self-rotating circles, and utilizes the circular self-rotating circles to rotate in the small winder to gradually wind the propylene packaging film body outside the film roller shaft around the cable body to be wrapped to play a wrapping and fixing role. In the process of the cable body to be wrapped in the circular self-rotating circle, two annular blocks for limiting the cable body to be wrapped are arranged on both sides of the small winder.

The propylene packaging film body that has been wound can be cut by a cutting knife to complete the entire winding operation.
