Further, the diameter of the rotating rod 4 is smaller than that of the lower sleeve 3, so that the rotating rod 4 can rotate in place.

Further, the lower casing 3 has a height smaller than the riser 12.

Further, the length of the upper casing 7 is any length greater than 10 cm.

Further, four angles of rubberizing board 8 are provided with two square hollow nut 81 respectively, through the fix with screw on rubberizing board 8, can be according to the position of the big or small regulation hollow nut 81 of rolling up core 9, and hollow nut 81 is the right angle and distributes.

Furthermore, the center of the four sides of the rubberizing plate 8 is a hollow structure 82, the width is 3-5cm, and the length is 8-10 cm.

The utility model has the advantages that: 1. the utility model can not slide in the process of stacking the winding cores, thereby avoiding the problem of asymmetrical pole ear; 2. the rubberizing board can rotate wantonly, and the experimenter accessible is fixed a position that needs to glue fast to this device, improves the fixed rubberizing efficiency of rolling up the core greatly.
