[0024] Specifically, the base 1 is partially fixed by inserting the groove 14 inside the fixing block 13 into the groove 10 inside the fixing hole 16, and the base 1 is fixed as a whole by the self-adhesive hot-melt adhesive layer 2, so as to achieve the effect of firmly fixing the base 1. One end of the connecting rod 6 is nailed into the inside of the construction wall, which can effectively prevent the self-adhesive hot-melt adhesive layer 2 from aging and causing the base 1 to fall off, requiring frequent maintenance, thereby improving the practicality of the base 1.

[0025] Reference Figure 1 , Figure 2 and Figure 4The fixed component includes a limit block 3, the upper surface of the limit block 3 is fixedly connected to the lower surface of the base 1, a limit groove 4 is provided inside the limit block 3, a reinforcing rubber strip 5 is slidably connected inside the limit block 3, the outer wall of the reinforcing rubber strip 5 is slidably connected to the inner wall of the limit groove 4, a metal mesh layer 15 is fixedly connected inside the base 1, a sliding ring 8 is slidably connected to the outer wall of the connecting rod 6, a clamping block 9 is fixedly connected inside the sliding ring 8, a fixing hole 16 is provided inside the limit block 3, the outer wall of the connecting rod 6 is slidably connected to the inner wall of the fixing hole 16, a limit groove 2 17 is provided inside the limit block 3, the outer wall of the clamping block 9 is attached to the inner wall of the limit groove 2 17, and a self-adhesive hot melt adhesive layer 2 is fixedly connected to the upper surface of the base 1.

[0026] Specifically, by fixing the metal mesh layer 15 inside the base 1, the compressive resistance of the base 1 is increased, and the performance of the base 1 in preventing water from penetrating the structure is improved. By setting a reinforcing rubber strip 5 inside the limit block 3, the fixing block 13 is rotated to make the clamping block 1 9 fit into the limit groove 2 17 to achieve the effect of fixing the reinforcing rubber strip 5, thereby further extending the service life of the base 1.
