This is especially true for beginners, as traditional chopsticks are not conducive to learning. Therefore, to facilitate and reduce the difficulty for young children in grasping chopsticks, training chopsticks specifically designed for beginners have been developed. These typically include a connecting section through which the two chopstick legs pass, securing them in place and preventing them from detaching, thus simplifying use. However, the connecting section of these training chopsticks is often a closed structure, secured either by clips or screws, making disassembly difficult and assembly relatively cumbersome. Adjusting the chopstick legs to different lengths also presents a relatively complex structural challenge. Summary of the Invention

For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0027] refer to Figure 1-5As shown, a flip-top training chopstick includes a connecting part 2 and two chopsticks 1. The connecting part 2 has two grooves 4 for the chopsticks 1 to pass through, and a fixing block 5 is provided between the two grooves 4. The sidewalls of the grooves 4 have elastic protrusions 6, and the chopsticks 1 have slots 7. When the slots 7 of the chopsticks 1 are aligned with the elastic protrusions 6, a portion of the elastic protrusions 6 is engaged in the slots 7, and the chopsticks 1 contact the fixing block 5. A cover plate 3 is hinged to the connecting part 2, covering the front end of the connecting part 2. The cover plate 2 is installed by rotation and can be flipped open, facilitating cleaning of the interior of the connecting part 2 and making it easier to install and remove the chopsticks, improving operational flexibility and reducing difficulty. The width of the grooves is greater than the width of the chopsticks to ensure that the chopsticks can swing left and right within the grooves, achieving clamping and opening. The cover plate conceals the elastic protrusions, grooves, and fixing block.

[0028] To facilitate positioning and engagement, the elastic protrusion 6 is cylindrical, and the groove 7 is formed in a ring around the radial direction of the chopstick 1. After the chopstick is adjusted to the required length, when the groove 7 is directly opposite the elastic protrusion 6, the elastic protrusion 6 is engaged in the groove 7 to form a fixed position. At this time, without any external force, the chopstick remains relatively fixed in the axial direction.

[0029] In addition, the top of the connecting part 2 is provided with a horizontally extending suspension arm 8, and the upper part of the cover plate 3 is provided with a mounting part. The mounting part is hinged to the suspension arm 8, so that the cover plate 3 can be flipped up and down.

[0030] The suspension arm 8 is provided with a receiving groove 9, and the mounting part of the cover plate 3 is a clearance groove 10. A fixed shaft 11 is provided in the clearance groove 10. The fixed shaft 11 is fitted in the receiving groove 9 and rotates in the receiving groove 9. By utilizing the clearance groove 10, the suspension arm 8 will not be blocked during rotation, thus realizing the flipping of the cover plate.

[0031] The connecting part 2 includes an outer shell 21 and an inner shell 22, which are fixedly connected to the outer shell 21. The suspension arm 8 is integrally formed on the outer shell 21. The sliding groove 4 and the fixing block 5 are provided on the inner shell 22, and the elastic protrusion 6 is provided on either the inner shell or the outer shell. The outer shell and the inner shell are installed and fixed using a snap-fit ​​structure, eliminating the need for screws and making installation more convenient. In this embodiment, the elastic protrusion is integrally formed on the outer shell, and then the elastic protrusion passes through the inner shell.

[0032] The fixing block 5, the elastic protrusion 6, and the inner shell 22 are all integrally molded from elastic rubber material. The fixing block abuts against the side wall of the chopsticks. To facilitate the adjustment of the chopsticks' length, the fixing block has a radial protrusion in the middle. In the sliding groove, the chopsticks contact the radial protrusion in the middle of the fixing block. There are gaps between the upper and lower parts of the fixing block and the chopsticks, which will not affect the clamping and opening of the chopsticks.

[0033] The width of the opening 12 of the receiving groove 9 is smaller than the diameter of the fixed shaft 11. The opening 12 of the receiving groove 9 refers to the axial opening of the receiving groove 9. The fixed shaft 11 enters the receiving groove 9 through the opening 12. When passing through the opening 12, it needs to be squeezed. After the fixed shaft 11 is installed inside the receiving groove 9, because the opening 12 is smaller than the fixed shaft 11, the fixed shaft 11 will not fall out of the opening 12. Both sides of the opening 12 are provided with guide inclined walls 13 that slope downwards outwards. The two guide inclined walls 13 form an "eight" shape, which is conducive to the installation of the fixed shaft and makes the assembly simpler and faster.

[0034] The fixing block 5 is provided with a locking key 14, and the cover plate 3 is provided with a through hole 15. The locking key 14 passes through the through hole 15 and is locked in place. A limiting baffle 16 is provided around the through hole 15 on the cover plate 3. The locking key 14 includes an integrally formed locking part 17 and an end 18. The locking part 17 is columnar, and the end 18 and the locking part 17 form a "T" shape. The width of the locking part 17 is smaller than the diameter of the end 18. A blocking wall 19 is formed between the end 18 and the locking part 17. The side wall of the through hole 15 of the cover plate 3 is locked onto the locking part 17, and the blocking wall 19 is attached to the limiting baffle 16, forming a stable assembly between the locking key 14 and the through hole 15, thus fixing the cover plate 3. When it is necessary to flip the cover plate 3, external force is required to press the locking key 14 or pull the cover plate 3 outward to disengage the locking key 14 from the through hole 15 of the cover plate 3, thereby allowing the cover plate 3 to flip smoothly. The locking key and the fixing block are molded as one piece and made of elastic rubber material.

[0035] In addition, the bottom of the fixing block 5 is provided with two limiting spring arms 20, which are inclined to both sides and respectively contact and abut against the two chopsticks 1. The two limiting spring arms are symmetrically arranged. When the two chopsticks are clamped together, they will squeeze the limiting spring arms. The limiting spring arms are deformed by the compression and generate a rebound force. When the chopsticks are released, the chopsticks will automatically open due to the rebound force of the limiting spring arms.

[0036] The outer shell 21 is provided with a support block 21 to facilitate the placement of the thumb and forefinger.

[0037] In this invention, multiple slots are pre-set on the chopsticks. The length of the chopsticks is adjusted according to the needs of different young children. The chopsticks move up or down in the connecting part, and after adjustment, an elastic protrusion engages in one of the slots, completing the axial positioning of the chopsticks. The cover plate and locking key are securely fastened, and the cover plate remains fixed in place. When two chopsticks are clamped together, the limiting spring arm is compressed. After releasing the clamping force, the limiting spring arm causes the two chopsticks to automatically reset and open. To adjust the length of the chopsticks, simply push or pull. Because the elastic protrusion is an elastic element, it will disengage from the slot when the external force is large. To open the top, pull the cover plate outwards to disengage the locking key, allowing the top to rotate around the fixed shaft.

[0038] It should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
