[0026] The following further elaborates on the invention in conjunction with the drawings and specific embodiments. The following description is merely exemplary and does not limit the protection scope of the invention.

[0027] Embodiment 1

[0028] As shown in Figures 1-4 the figure, a pair of chopsticks that can be used as both public and private chopsticks includes two chopstick handles 1 and two chopstick tips 2 that are correspondingly and movably connected to the lower ends of the two chopstick handles 1; the upper ends of the two chopstick handles 1 are connected by a connecting sleeve 3, and the inside of the chopstick handles 1 communicates with the inside of the connecting sleeve 3. Through this setting, the two chopstick handles 1 form an integral body to facilitate use and storage, etc.; a button 4 is provided on the side wall of one chopstick handle 1, and two drawstrings 5 arranged inside the two chopstick handles 1 are connected to the inside of the button 4; one end of each of the two drawstrings 5 is fixedly arranged, and the other ends of the two drawstrings 5 are correspondingly connected to two clamping mechanisms 6 respectively arranged on the two chopstick handles 1; the two clamping mechanisms 6 are correspondingly connected to two flipping mechanisms 7 respectively arranged on the two chopstick tips 2; two positioning parts 9 that are axially distributed along the chopstick tip 2 and symmetrically arranged and cooperate with a clamping mechanism 6 are provided on the side wall of each chopstick tip 2. By pressing the button 4, the drawstrings 5 drive the clamping mechanism 6 to be engaged or disengaged with the positioning part 9, and the two flipping mechanisms 7 are driven by the clamping mechanism 6 to realize the flipping and swapping of the two ends of the chopstick tip 2. Preferably, in order to facilitate picking up food, the two chopstick tips 2 are respectively arranged inside the two chopstick handles 1. In the present invention, by providing the chopstick tips 2 with two ends that can be flipped and swapped on the chopstick handle 1, people can freely swap the two ends of the chopstick tips 2, achieving the effect of combining public chopsticks and private chopsticks into one, and the chopstick tips 2 will not contact the chopstick handle 1 during the rotation process to prevent infection, thus greatly facilitating people's use and having strong practicability.

[0029] Specifically, a perforation is provided inside the button 4, and the two drawstrings 5 are both threaded through the perforation, so that when the button 4 is pressed, the two drawstrings 5 will be bent and deformed, thereby driving the clamping mechanism 6. At the same time, this setting method can facilitate assembly, that is, improve production efficiency.

[0030] Among them, the chopstick tip 2 includes a first end 21, a second end 22, and a connecting block 23 for connecting the first end 21 and the second end 22. Specifically, the two positioning parts 9 on each chopstick tip 2 are respectively arranged on the first end 21 and the second end 22; the flipping mechanism 7 is arranged on the connecting block 23. Setting the chopstick tip 2 in a three-section form can facilitate assembly. Specifically, when in use, the first end 21 can be the public chopstick end, and the second end 22 is the private chopstick end.

[0031] Each clamping mechanism 6 includes a slider 61, a first return spring 62, a second return spring 63 and a clamping strip 8; the clamping strip 8 can be turned upside down and arranged on the side wall of the chopstick handle 1, and its upper end passes through the chopstick handle 1, and the lower end of the clamping strip 8 is engaged with the clamping portion 9; the slider 61 can be moved up and down in the chopstick handle 1, one side of the slider 61 is connected to the upper end of the clamping strip 8, the upper end of the slider 61 is fixedly connected to one end of a pull rope 5, and the lower end of the slider 61 is connected to a flip mechanism 7. The first return spring 62 is vertically fixed to the top of the slider 61. Specifically, a block formed integrally with the chopstick handle 1 is also provided on the top of the first return spring 62, so that the first return spring 62 is clamped between the block and the slider 61. The second return spring 63 is transversely fixed to one side of the clamping strip 8 and one end thereof is connected to the upper end of the clamping strip 8. Specifically, a clamping column formed integrally with the chopstick handle 1 is provided in the chopstick handle 1, and the second return spring 63 is sleeved on the clamping column. As a specific embodiment, a first inclined surface 611 inclined from top to bottom and from outside to inside is provided on one side of the slider 61, and the first inclined surface 611 is connected to the upper end of the clamping strip 8. Specifically, the connection mode of the first inclined surface 611 and the clamping strip 8 is contact connection. By setting the first inclined surface 611, the clamping strip 8 can be driven to flip when the slider 61 moves upward. More specifically, a rotating column 80 is integrally formed on both sides of the clamping strip 8 and the two rotating columns 80 are rotatably clamped in the chopstick handle 1, so that the clamping strip 8 can be turned upside down;

[0032] Preferably, the lower end of the positioning strip 8 is block-shaped; the positioning portion 9 is groove-shaped to match the positioning strip 8, and the chopstick head 2 can be fixed by inserting the lower end of the positioning strip 8 into the positioning portion 9. However, it should be noted that there can be other ways to specifically set the lower end of the positioning strip 8 and the positioning portion 9, for example: 1. The lower end of the positioning strip 8 is fork-shaped, and the positioning portion 9 is an arc-shaped surface, so that the lower end of the positioning strip 8 can be directly forked at the position corresponding to the positioning portion 9 to fix the chopstick head 2; 2. The lower end of the positioning strip 8 is ring-shaped, and the positioning portion 9 is a convex block-shaped to match the positioning strip 8, so that the other end of the positioning strip 8 can also be clamped on the positioning portion 9 in a sleeve-shaped manner to fix the chopstick head 2. For ease of understanding, in this embodiment, the other end of the positioning strip 8 is block-shaped; the positioning portion 9 is groove-shaped to match the positioning strip 8.

[0033] like Figure 4 As shown, the side surfaces of the two locking portions 9 in each chopstick head 2 facing each other are second inclined surfaces 91; the bottom surface of the lower end of the locking strip 8 is an arc surface that matches the second inclined surface 91. The above arrangement enables the locking strip 8 to move more smoothly without causing jamming.

[0034] Each flipping mechanism 7 includes a spring (not shown in the figure), a rotating shaft 71, and a transmission rope 72; the spring is located between two clamping parts 9 and is fixed inside the chopstick head 2. Specifically, the spring is fixed inside a hollow structure of the connecting block 23; one end of the rotating shaft 71 is fixedly connected to the outer end of the spring, and the other end of the rotating shaft 71 is clamped inside the chopstick handle 1 so that the chopstick head 2 is connected to the chopstick handle 1. The side wall of the rotating shaft 71 is fixedly connected to the chopstick head 2. That is, because the side wall of the rotating shaft 71 is fixedly connected to the connecting block 23, when the rotating shaft 71 rotates, it can drive the chopstick head 2 to rotate; one end of the transmission rope 72 is wound around the other end of the rotating shaft 71 for several turns, and the other end of the transmission rope 72 is fixedly connected to the lower end of the slider 61. In order to make the connection between the rotating shaft 71 and the connecting block 23 better, a contact ring with an outer diameter larger than the diameter of the rotating shaft 71 is integrally formed on the side wall of the rotating shaft 71, and the rotating shaft 71 is connected to the connecting block 23 through this contact ring.

[0035] In each of the two chopstick handles 1, a limiting mechanism is further provided which is fixed below the slider 61 and is used to limit the slider 61. Specifically, the limiting mechanism includes a limiting block 10 fixed below the slider 61. Preferably, the limiting block 10 is integrally formed with the chopstick handle 1. By providing the limiting mechanism, the slider 61 can be prevented from deviating from the preset route, so that the slider 61 can move within a certain range.

[0036] As Figure 2 shown, two fixing blocks 11 are also fixed in one chopstick handle 1, which are respectively located above and below the button 4. One end of each of the two pulling ropes 5 is fixed to the two fixing blocks 11 respectively. Preferably, both of the two fixing blocks 11 are integrally formed with the chopstick handle 1. For the sake of easy understanding, the two pulling ropes 5 are respectively designated as the first pulling rope 51 and the second pulling rope 52. One end of the first pulling rope 51 passes upward through the through hole on the button 4 and is fixedly connected to the fixing block 11 located above the button 4, and the other end of the first pulling rope 51 is fixedly connected to a slider 61; one end of the second pulling rope 52 passes downward through the through hole on the button 4 and is fixedly connected to the fixing block 11 located below the button 4, and the other end of the second pulling rope 52 passes through the connecting sleeve 3 and penetrates into the other chopstick handle 1 and is fixedly connected to the other slider 61. Through the above structure, the button 4 can drive the first pulling rope 51 and the second pulling rope 52 to act synchronously, so that the first pulling rope 51 and the second pulling rope 52 can drive the two sliders 61 to act synchronously, and further drive the two flipping mechanisms 7 to act synchronously through the two sliders 61, with a clever design.

[0037] For the convenience of using the chopsticks, the connecting sleeve 3 has elasticity. When the user picks up vegetables, the fingers need to exert force to make the two chopstick heads 2 approach so as to pick up vegetables. When the fingers are released, the two chopstick heads 2 separate and are in a natural state.

[0038] The working principle of the present invention is introduced below for understanding the present invention:

[0039] First, when it is necessary to convert the first end 21 of the two chopstick heads 2 to the second end 22, press the button 4 to move it inward, so that the two draw ropes 5 are bent and deformed simultaneously and drive the slider 61 to move upward. During the movement of the slider 61, the first return spring 62 contracts. And because the first inclined surface 611 of the slider 61 contacts the upper end of the clamping strip 8, the first inclined surface 611 drives the upper end of the clamping strip 8 to flip upward during the movement and makes the second return spring 63 contract, while the lower end of the clamping strip 8 synchronously flips downward and leaves the clamping portion 9 of the first end 21 of the chopstick head 2. When the clamping strip 8 leaves the clamping portion 9, at this time the slider 61 just drives the transmission rope 72 to be pulled out upward, so that the rotating shaft 71 rotates. At the same time, the spring unwinds and the chopstick head 2 flips. When the chopstick head 2 flips 180° and reaches the preset position, the transmission rope 72 stops, that is, the first end 21 and the second end 22 of the chopstick head 2 have completed the flip and exchange. Then release the button 4, so that the first return spring 62 and the second return spring 63 reset and drive the clamping strip 8 and the button 4 to reset. Immediately afterwards, the lower end of the clamping strip 8 just snaps into the clamping portion 9 of the second end 22 of the chopstick head 2, making the chopstick head 2 unable to rotate. In this way, one flip and exchange of the two ends of the chopstick head 2 is completed. It should be noted that before the chopstick head 2 flips, the transmission rope 72 is in a non-tight state, so that the clamping strip 8 has enough position to leave the clamping portion 9 during the flip and will not damage the rotating shaft 71. When the clamping strip 8 leaves the clamping portion 9, the transmission rope 72 drives the rotating shaft 71 to rotate.

[0040] Similarly, when it is necessary to perform another flip and exchange of the two ends of the chopstick head 2, just press the button 4 again, so that the slider 61 moves upward, the first return spring 62 and the second return spring 63 contract, and the clamping strip 8 disengages from the clamping portion 9 of the second end 22 of the chopstick head 2. At this time, since there is no force acting on the spring, the spring winds up, thereby driving the rotating shaft 71 to reset and making the transmission rope 72 wind around the rotating shaft 71, and then driving the chopstick head 2 to flip 180° in the opposite direction. After the flip is completed, release the button 4. At this time, the first return spring 62 and the second return spring 63 reset, making the button 4 reset and the lower end of the clamping strip 8 snap into the clamping portion 9 of the first end 21 of the chopstick head 2 again. In this way, another flip and exchange of the two ends of the chopstick head 2 is completed.

[0041] Embodiment 2:

[0042] Such as Figure 5 and Figure 6As shown, the difference between this embodiment and the first embodiment is that the clamping position portion 9 is a convex post; the clamping mechanism 6 includes a slider 61 and a first return spring 62; the slider 61 is movably arranged up and down in the chopstick handle 1, the upper end of the slider 61 is fixedly connected to one end of a pull rope 5, the lower end of the slider 61 is connected to a flipping mechanism 7, and in this embodiment, the connection manner between the slider 61 and the flipping mechanism 7 is the same as that between the slider 61 and the flipping mechanism 7 in the first embodiment, which will not be specifically described here; the first return spring 62 is vertically fixed on the top of the slider 61; a clamping groove 64 for clamping the clamping position portion 9 is provided at the bottom of the slider 61, and a flipping through hole 101 for cooperating with the clamping position portion 9 and for the clamping position portion 9 to enter and exit is provided on the side wall of the chopstick handle 1.

[0043] Specifically, when in use, first, the clamping position portion 9 at the first end 21 of the chopstick head 2 is clamped in the clamping groove 64. By pressing the button 4, the pull rope 5 drives the slider 61 to move upward, so that the clamping groove 64 is separated from the clamping position portion 9, that is, the clamping position portion 9 is separated from the slider 61. During the upward movement of the slider 61, the flipping mechanism 7 drives the chopstick head 2 to flip 180°. When flipping, the clamping position portion 9 at the first end 21 of the chopstick head 2 leaves the flipping through hole 101 and the clamping position portion 9 at the second end 22 turns into the flipping through hole 101. When the button 4 is released, the slider 61 moves downward through the reset of the first return spring 62 so that the clamping groove 64 clamps the clamping position portion 9 at the second end 22 of the chopstick head 2, thereby fixing the chopstick head 2. In this way, one flipping and swapping of the two ends of the chopstick head 2 is completed.

[0044] Similarly, when it is necessary to perform another flipping and swapping of the two ends of the chopstick head 2, only need to press the button 4 again, so that the slider 61 moves upward and separates from the clamping position portion 9 at the second end 22 of the chopstick head 2. At this time, the flipping mechanism 7 resets, and then drives the chopstick head 2 to flip 180° in the opposite direction, so that the clamping position portion 9 at the first end 21 of the chopstick head 2 is re-turned into the flipping through hole 101. After the flipping is completed, release the button 4. At this time, the slider 61 resets so that the clamping position portion 9 is clamped into the clamping groove 64 again. In this way, another flipping and swapping of the two ends of the chopstick head 2 is completed.

[0045] The present invention is not limited to the above embodiments. If various changes or deformations to the present invention do not depart from the spirit and scope of the present invention, and if these changes and deformations belong to the scope of the claims of the present invention and equivalent technical scope, then the present invention also intends to include these changes and deformations.
