[0029] In this embodiment, by setting up the installation mechanism 22, after the installation of the rectangular block 215 is completed, the operator can rotate the adjustment block 223 to make the adjustment block 223 rotate with the sleeve block 221. After the sleeve block 221 rotates, it will move with the limiting column 222.
