It improves the stability of the installation plate 13 sliding. When the installation plate 13 moves, the installation plate 13 drives the rotating sleeve 21 to move through the fixed column 20. The rotating sleeve 21 drives the twisting block 19 to move through the rotating block 28. The twisting block 19 which is provided as a waist-shaped block penetrates the waist-shaped hole opened in the middle of the protective sleeve 10. Then the operator rotates the twisting block 19 again. The waist-shaped block provided by the twisting block 19 is no longer aligned with the waist-shaped hole opened in the middle of the protective sleeve 10.
