A top end of the column is formed with an inner thread section. The sleeve has an axial through hole corresponding to the column, whereby the sleeve can be fitted around the column. The sleeve is fixed on the subplate by a bolt corresponding to the inner thread section of the column. An outer diameter of the head section is larger than an inner diameter of the through hole. The bolt is downward fitted into the sleeve and screwed into the inner thread section of the column. The head section of the bolt is stopped at the top edge of the sleeve to fix the sleeve.
