Two sets of connecting blocks 5 are symmetrically arranged at both ends of the lower clamping plate 4. A sliding groove 7 is formed at the center of the bottom end of each mounting block 2. Two sets of sliding rods 13 are symmetrically fixed at both ends inside the sliding groove 7. Springs are sleeved on the outer walls of the two sets of sliding rods 13. Spring 14, slider 8 is adapted to be connected inside the sliding groove 7, two sets of locking rods 9 are symmetrically fixed on both sides of the inner wall of slider 8, and a U-shaped pull handle 11 is fixedly connected to the middle of the outer wall of slider 8. Two sets of locking holes 15 are symmetrically opened on both sides of the outer wall of docking block 5. The upper clamping plate 1 and the lower clamping plate 4 can be adapted to be connected and clamped to hold the heat insulation cotton. When installing heat insulation cotton, the end of the heat insulation cotton can be quickly clamped, thereby enabling the heat insulation cotton to be quickly installed and disassembled, greatly improving the convenience of heat insulation cotton installation, maintenance and replacement.

[0024] like Figure 3 As shown, the slider 8 and the slide groove 7 are matched and connected. The two sets of slide rods 13 slide through the interior of the slider 8, and the slider 8 and the slide rods 13 form a sliding connection. The two ends of the spring 14 are respectively attached to the side wall of the slider 8 and the side wall of the slide groove 7. The slider 8 is adapted to the interior of the slide groove 7, and the slider 8 will slide on the two sets of slide rods 13 during the sliding process to ensure that the slider 8 slides stably on the two sets of slide rods 13. The spring 14 set on the slide rods 13 will give the slider 8 elasticity.
