[0018] FIG1 is an exploded schematic diagram of the present invention. FIG2 is a schematic diagram of the three-dimensional appearance of the present invention after assembly. FIG3 is a partial enlarged schematic diagram of the assembly structure of the present invention. FIG4 is a cross-sectional view of the assembled device of the present invention. Implementation Method

[0019] As shown in Figures 1 to 4, the present invention provides a combination of chopsticks made of different materials, which mainly consists of a clamping rod 11, a gripping rod 21, and a combination member 31 disposed between the clamping rod 11 and the gripping rod 21, which are connected to each other to form a chopstick body structure, wherein:

[0020] The clamping rod 11 is made of metal. Preferably, the clamping rod 11 can be made of titanium in an elongated strip shape, which has the advantages of being non-toxic, lightweight, high in strength, corrosion-resistant, and having a low thermal conductivity. The clamping rod 11 is used to form the clamping section of the chopstick body that can clamp food relative to the chopstick body, and a circular hole 12 is formed at one end of the clamping rod 11.

[0021] The grip 21 is made of a long strip of non-metallic material. The non-metallic material can be made of plastic or wood, etc., which has a surface anti-slip property better than that of metal, and is used to form a grip section of the chopstick body that can be grasped by a human hand. The grip 21 is integrally extended at one end to form a cylindrical sleeve portion 22 protruding along its long axis, and the outer diameter of the sleeve portion 22 is smaller than the outer diameter of the grip 21, so that an abutment surface 23 is formed at the intersection of the grip 21 and the sleeve portion 22, and a first chamfered portion 24 is formed along the outer side corner of the abutment surface 23, and a first latch portion 25 is recessed on the outer circumferential surface of the sleeve portion 22 near its root. In this embodiment, the first latch portion 25 is composed of a slot surrounding the outer circumferential surface of the sleeve portion 22, and a second chamfered portion 26 is provided at the extended end of the sleeve portion 22.

[0022] The assembly 31 is made of a plastic material and is integrally injection molded. The assembly 31 has a cylindrical assembly portion 32 and a blocking portion 33 connected to the assembly portion 32 and having an outwardly expanding annular shape. The assembly portion 32 and the blocking portion 33 can respectively constitute the two ends of the assembly 31. The end 321 of the assembly portion 32 relatively away from the blocking portion 33 is tapered, and the assembly portion 32 is relatively inserted and fixed to the assembly hole of the clamping rod 11. 12, the end portion 321 of the assembly portion 32 is tapered to enhance assembly ease, and the maximum outer diameter of the assembly portion 32 is equal to or slightly larger than the inner diameter of the assembly hole 12, so that the outer peripheral surface of the assembly portion 32 (excluding the tapered end) can form a tight-fitting abutment engagement with the inner edge of the assembly hole 12. In addition, adhesive can be additionally applied between the assembly portion 32 and the assembly hole 12 to further enhance their bonding strength.

[0023] The blocking portion 33 of the assembly 31 is provided with a circular hole-shaped sleeve hole 331 extending in the direction of the assembly portion 32, and the sleeve hole 331 is relatively sleeved on the sleeve portion 22 of the grip 21, and a second latch portion 34 is formed on the inner edge of the sleeve hole 331 to be mutually locked with the first latch portion 25. In this embodiment, the second latch portion 34 is composed of two annular ridges arranged at intervals, so that when the sleeve hole 331 of the assembly 31 is relatively sleeved on the sleeve portion 22 of the grip 21, the two annular ridges can be correspondingly snapped into the first latch portion 25 composed of the slots, thereby achieving the positioning of the grip 21. The blocking portion 33 has a blocking surface 332 formed on two opposite sides facing the clamping rod 11 and the gripping rod 21. When the assembly hole 12 of the clamping rod 11 and the sleeve portion 22 of the gripping rod 21 are respectively engaged with the assembly portion 32 and the sleeve hole 331 of the assembly 31, the open end of the assembly hole 12 and the contact surface 23 of the gripping rod 21 are respectively abutted and positioned on the corresponding blocking surface 332, so that the assembly 31 can be used to combine and limit the clamping rod 11 and the gripping rod 21 to form the chopstick body structure. After the chopsticks are assembled into the chopstick body, the outer peripheral surface of the blocking portion 33 can directly constitute a marking portion exposed on the surface of the chopstick body.

[0024] The invention composed of the above structure has the following advantages:

[0025] 1. The heterogeneous material combination chopsticks provided herein have a clamping rod 11 and a gripping rod 21 made of metal and non-metallic materials, respectively. This allows the clamping section of the chopstick body to be hygienic and safe, while the gripping section provides a comfortable and non-slip grip.

[0026] 2. In this invention, the assembly portion 32 of the assembly 31 is fixedly connected to the assembly hole 12 of the clamping rod 11 in a tight fit. At the same time, the assembly 31 is made of plastic material and has a slight elasticity, which ensures that the connection between the assembly 31 and the clamping rod 11 is strong and not easily loosened. The grip rod 21 is connected by the first latch portion 25 on the sleeve portion 22 and the second latch portion 34 in the blocking portion 33. It has the effect of being quickly disassembled and conveniently replacing different grip rods 21.

[0027] 3. By connecting the clamping rod 11 with the assembly 31, the present invention simplifies the manufacturing process of the clamping rod 11. That is, the clamping rod 11 made of metal material only needs to be formed with the assembly hole 12 at one end, and no additional turning process (such as turning a concave and convex structure such as a thread) is required. Therefore, the manufacturing time and cost of the clamping rod 11 made of metal material can be greatly reduced, making the clamping rod 11 made of metal material easier to manufacture.

[0028] 4. In the heterogeneous material combination chopsticks provided by the present invention, when the assembly hole 12 of the clamping rod 11 and the sleeve portion 22 of the gripping rod 21 are respectively engaged with the assembly portion 32 and the sleeve hole 331 of the assembly member 31, the blocking surface 332 formed on the blocking portion 33 of the assembly member 31 not only provides a positioning function for the open end of the assembly hole 12 and the abutment surface 23 of the gripping rod 21 to abut against each other, but also, after the chopsticks are assembled into a body, the outer peripheral surface of the blocking portion 33 can be directly formed and exposed on the surface of the chopstick body, thereby providing an additional marking function. Therefore, it is only necessary to further manufacture the assembly member with a specific color to allow the user to intuitively and quickly identify the chopstick body (for example, to distinguish between male and female chopsticks, or to identify the owner of the chopsticks).

[0029] 5. The present invention further forms a first chamfered portion 24 at the outer corner of the abutment surface 23 of the grip 21. When the abutment surface 23 of the grip 21 abuts against the corresponding blocking surface 332 of the blocking portion 33, an annular groove 41 is formed between the grip 21 and the assembly 31 on the surface of the chopstick body. The annular groove 41 not only serves as a reminder of the docking position, but also allows the user to insert a fingernail to apply force, thereby making the grip 21 easy to disassemble and replace.

[0030] The above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Any replacement of equivalent elements should still fall within the scope of the present invention.

[0031] In summary, those familiar with the art will understand that the present invention can indeed achieve the aforementioned objectives and is in compliance with the provisions of the Patent Law, so an application can be filed in accordance with the law.
