The present invention relates to a detachable connection unit having flexibility due to a unique structure thereof and a cap having the same. To solve the above-mentioned problem, the detachable connection unit comprises: a first connection body connected to a first part; and a second connection body connected to a second part, wherein the first part and the second part are connected in a detachable manner. The first connection body comprises: a first frame portion which defines an outer circumference formed to be elongated, and which includes an upper frame and a lower frame; a plurality of first support portions of which both end portions are respectively connected to the upper frame and the lower frame of the first frame portion, form an oblique angle with respect to a longitudinal central axis of the first frame portion, and are arranged at regular intervals; a plurality of second support portions of which both end portions are respectively connected to the upper frame and the lower frame of the first frame portion, form an oblique angle with respect to the longitudinal central axis of the first frame portion, and are arranged at regular intervals, wherein the second support portions intersect with the first support portions; and a plurality of protruding portions which are formed at regular intervals, are arranged on a straight line that connects intersecting points of the first support portions and the second support portions, and are fixed to both the first support portions and the second support portions. The second connection body comprises a plurality of insertion holes formed in corresponding parts with the plurality of protruding portions. |
