The present invention relates to a multi-size tube holder. The multi-size tube holder according to an embodiment of the present invention comprises: a tube holder body (10); a first fixing unit (20) which includes a first elastic plate (21) having a symmetric shape inclined downward from the upper end of both side walls of the tube holder body (10) to the center, and a first support portion (22) disposed in the center of the lower face of the tube holder body (10) and having a forward-facing semi-circular groove at the upper center; and a second fixing unit (30) which includes a second elastic plate (31) having a symmetric shape inclined downward from the upper end of both side walls of the tube holder body (10) to the center, and a second support portion (32) disposed at the center of the lower face of the tube holder body (10) and having a forward-facing semi-circular groove at the upper center. According to the present invention, even when sizes of tubes are different, the tubes can be coupled by one tube holder, and thus it is possible to reduce development costs and production costs according to new development and production of a tube holder. In addition, it is possible to lower the defect occurrence rate caused by worker error. |
