The present invention relates to a learning tool having a straight flexible tube. The present invention provides a learning tool having a straight flexible tube, comprising: a straight tool connecting member (100) comprising a wrinkled tube (110), which is fabricated according to a predetermined specification in the shape of a circular pipe using a polypropylene (PP) material, and which has multiple winkles formed thereon to have a flexible function such that the same can bend freely in a 360° angular direction, and a pair of fastening tubes (120), which are connected to and integrated with both ends of the wrinkled tube, respectively, and to which a connecting member is fastened such that, when a learning tool is fabricated, the overall shape of the tool is formed; and a connecting member (200) comprising a pair of conical connectors (210) for connecting the straight tool connecting member (100) as a whole, the pair of conical connectors (210) being made of one selected from elastic rubber and synthetic resin and being bonded into a circular pipe of the connecting member (200) using an adhesive together with the pair of fastening tubes (120), the connecting member (200) comprising, at the center thereof, a circular flange (211) provided so as to distinguish the boundary between the straight tool connecting member and the connecting member and fastening portions (212) provided on the left and right sides, about the circular flange, respectively, threads being formed on the fastening members (212), such that the straight tool connecting member and the connecting member can be mounted/detached, the fastening portions having cones (213) provided such that the pair of conical connectors (210) can be easily inserted into the straight tool connecting member (100) and the connecting member (200) and markings (220) provided to indicate lengths ranging from a mm unit to a cm unit such that, when a learning tool is fabricated, the user can predict the size of the tool. The present invention has unique advantages in that, since bending is free in the 360° angular direction, it is possible to manufacture a learning tool in various contours/shapes desired by the user, and interest in mathematics and learning effects related to various figures can be multiplied. |
