A clamp structure for use on different diameter bars mainly structured to include upper clamp pieces, lower clamp pieces, a set of first spacers and a set of second spacers, wherein joining portions and through holes are located on the upper clamp pieces, and embedding grooves are defined in bottom edges of the upper clamp pieces. Corresponding positions of the lower clamp pieces are similarly disposed with through holes and binding embedding grooves. Clamping spaces are thus formed between the upper clamp pieces and the lower clamp pieces after lining the joining portions with the first spacers, which enable clamping a bar of relatively large diameter. Moreover, clamping spaces formed between the upper clamp pieces and the lower clamp pieces after additionally lining the joining portions with the second spacers enable clamping a bar of relatively small diameter. |
