[0007] Furthermore, in order to facilitate the rotation operation of the inner top rotating plate, the inner side end of the inner top rotating plate is set to an arc structure.

[0008] Furthermore, in order to facilitate the rotation operation of the inner top rotating plate, a handle is provided at the outer end of the inner top rotating plate.

[0009] Furthermore, in order to prevent hot air from escaping from the larger gaps between the semi-arc-shaped pieces during the heat shrinking process, thereby affecting the heat shrinking effect, a pair of wing plates are provided on the outer periphery of the semi-arc-shaped pieces;

[0010] A waist-shaped hole is provided on a wing plate located on a semi-arc-shaped member;

[0011] The outer wall of the wing plate located on the other semi-arc-shaped member is formed with a right-angled trapezoidal platform, the inner side end of the right-angled trapezoidal platform is an inclined surface, and a moving hole is opened on the wing plate, the moving hole passes through the right-angled trapezoidal platform, and a pair of avoidance holes are opened on the moving hole;
