[0002] Chopsticks require complex hand coordination and fine finger control, which is particularly difficult for children. At the same time, learning to use chopsticks can exercise eye-hand coordination, promote brain development, and strengthen finger muscle strength. Therefore, children's training chopsticks are becoming more and more important. There are many types of training chopsticks on the market, but all of them have the problem of jamming when the chopsticks are clamped or opened, resulting in poor training results.

[0003] For example, the patent document with patent application number CN202223057595.3 and announcement date 2023.03.24 discloses a pair of detachable and easy-to-clean children's learning and training chopsticks, which includes two connecting bodies, which are limited between the front shell and the rear shell and can rotate, one connecting body and the first chopstick rod are a first detachable connecting structure, and the other connecting body and the second chopstick rod are a second detachable connecting structure, the first detachable connecting structure is a snap-fit ​​structure or a screw-fit structure, and the second detachable connecting structure is a snap-fit ​​structure or a screw-fit structure. In the above documents, the chopstick rods are connected to the connecting bodies by screw-fit structures or snap-fit ​​structures, so that The chopstick rod is easy to disassemble and firmly connected, and is suitable for children to use. The chopstick rod of the training chopsticks only moves in the space formed after the front shell and the rear shell are connected through the rotating shaft, and the rotating shaft can only limit the radial direction of the chopstick rod. When the training chopsticks fall or encounter an impact, the chopstick rod is likely to be separated from the rotating shaft direction and thus separated, so that the chopstick rod cannot be axially limited, and the structural reliability of the training chopsticks is poor. At the same time, the front shell and the rear shell are only clamped by edge clamping, and it is easy to be improperly assembled during the clamping process, which affects the problem of inconvenient assembly.
