Detailed Description

It should be noted that, without conflict, the embodiments of the present utility model and features of the embodiments may be combined with each other, and the present utility model will be further described in detail with reference to the drawings and the specific embodiments.

In the embodiment of the present utility model, if there is a directional indication (such as up, down, left, right, front, and rear … …) only for explaining the relative positional relationship, movement condition, etc. between the components in a specific posture (as shown in the drawings), if the specific posture is changed, the directional indication is correspondingly changed.

In addition, the description of "first," "second," etc. in this disclosure is for descriptive purposes only and is not to be construed as indicating or implying a relative importance or implying an indication of the number of features being indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature.

Referring to fig. 1 to 9, the portable chopstick assembly according to the embodiment of the present utility model includes a pair of chopsticks. The chopsticks consist of an upper chopstick and a lower chopstick.

The upper chopstick is tubular with two open ends, the outer diameter of the lower chopstick is matched with the inner diameter of the upper chopstick, the inner wall of the bottom of the upper chopstick is provided with internal threads, the top of the lower chopstick is correspondingly provided with external threads, and the periphery of the top of the lower chopstick is provided with a reverse taper surface which is used for being embedded with the inner wall of the top end of the upper chopstick. When in use, the bottom of the upper chopstick is connected with the top of the lower chopstick through threads; when the chopsticks are folded, the lower chopsticks are inserted into the upper chopsticks from the opening at the top of the upper chopsticks, the inverted conical surface is clung to the inner wall of the upper chopsticks, the inverted conical surface and the inner wall of the upper chopsticks can form good cooperation, the chopsticks are not easy to loose and deviate from, and no great force is needed when the chopsticks are pulled out. Preferably, the inverted cone is an inverted cone of less than 1 degree.

The lengths of the upper chopsticks and the lower chopsticks are approximate (namely the lengths are in the preset range), and the lengths of the upper chopsticks and the lower chopsticks are almost the same, so that the length after being folded is shorter, and the carrying is convenient.
