Specific embodiments

[0013] As Figure 1-2 shown, an embodiment of the present utility model provides a chemically cross-linked heat-shrinkable sleeve, which includes an I-shaped cylinder 1. A tube body 2 is wound around the surface of the I-shaped cylinder 1. A movable groove 3 is opened on the right side of the I-shaped cylinder 1. A rotating block 4 is movably connected inside the movable groove 3. A connecting plate 5 is fixedly connected to the right side of the rotating block 4. The left side of the connecting plate 5 abuts against the right side of the I-shaped cylinder 1. A vertical rod 8 is fixedly connected to the upper surface of the connecting plate 5. A horizontal rod 9 is fixedly connected to the left side of the vertical rod 8. A clamping cover 10 is fixedly connected to the left end of the horizontal rod 9. A spring 11 is fixedly connected to the inner top wall of the clamping cover 10. A pressing plate 12 is fixedly connected to the bottom end of the spring 11. The right side of the pressing plate 12 abuts against the right inner wall of the clamping cover 10. A threaded groove 7 is opened on the left inner wall of the movable groove 3.
