[0028] The embodiments of the present utility model will be described below with reference to the accompanying drawings. In the process, to ensure the clarity and convenience of the description, we may exaggerate the width of the lines or the size of the components in the drawings.

[0029] In addition, the terms used below are defined based on the functions in the present utility model and may vary according to the intentions or conventions of users and operators. Therefore, these terms are defined based on the entire content of this specification.

[0030] As Figures 1 to 10 shown, an adjustable-length chopstick includes a chopstick body 1 and a chopstick head 2. The chopstick head 2 is threadedly connected to the lower end of the chopstick body 1 for easy disassembly and replacement. A rotating hole 101 is provided on the upper surface of the chopstick body 1. A placing hole 102 is provided at the bottom of the rotating hole 101. Two sliding grooves 105 are vertically provided on the inner wall of the placing hole 102. The structures of the two sliding grooves 105 are arc-shaped grooves. The two sliding grooves 105 are arranged opposite to each other. Three grooves 103 are evenly provided on the inner wall of the placing hole 102. The structures of the three grooves 103 are annular arc-shaped grooves. Two limiting holes 104 are provided at the bottom of the groove 103. The two limiting holes 104 are arranged opposite to each other, and the straight line connecting the centers of the two limiting holes 104 is perpendicular to the plane where the centers of the two sliding grooves 105 are located. The end of the limiting hole 104 is provided with a rounded corner. An anti-slip part 108 is provided on the outer circumferential surface of the upper end of the chopstick body 1. The structure of the anti-slip part 108 is a bamboo joint-shaped convex ring.

[0031] The placement hole 102 is provided with an extension rod 3, and the extension rod 3 includes a rotating portion 31, and the rotating portion 31 is rotatably arranged in the rotating hole 101. A connecting portion 32 is provided at the bottom of the rotating portion 31, and the connecting portion 32 is located in the placement hole 102. A sliding portion 33 is provided at the lower end of the connecting portion 32, and the sliding portion 33 is slidably arranged in the placement hole 102. Two mounting holes 34 are provided on the outer circumferential surface of the sliding portion 33, and the two mounting holes 34 are arranged opposite to each other. The limiting mechanism 6 slides along the slide groove 105 and the inner wall of the groove 103. The top of the rotating part 31 is provided with a rotating head 35. The extension rod 3 is inserted into the placement hole 102 of the chopstick body 1 through the rotating head 35. After the two limiting mechanisms 6 are aligned with the two slide grooves 105, they are continuously pressed down to make the head of the limiting mechanism 6 roll along the inner wall of the slide groove 105, and then the sliding part 33 slides into the placement hole 102. When the sliding part 33 slides to the bottom of the placement hole 102, the head of the limiting mechanism 6 is just aligned with the lowermost end. The grooves 103 are located at the same height. At this time, the rotating head 35 is rotated to make the head of the limiting mechanism 6 roll along the inner wall of the groove 103 until the head of the limiting mechanism 6 rolls into the limiting hole 104 to limit and fix the extension rod 3 in the chopstick body 1. When the overall length of the chopsticks needs to be adjusted, a certain force is applied to rotate the rotating head 35. Since the end of the limiting hole 104 is rounded, the head of the limiting mechanism 6 is more likely to roll along the rounded corner to break away from the limiting hole 104 when subjected to force. When the head of the limiting mechanism 6 rolls into the slide groove 105 When the chopsticks are in contact with the wall, pull the rotating head 35 upward until the head of the limiting mechanism 6 contacts the inner wall of another groove 103. At this time, rotate the rotating head 35 to make the head of the limiting mechanism 6 rotate along the inner wall of the groove 103 into the limiting hole 104, and limit and fix the extension rod 3 again. At this time, the upper end of the rotating part 31 extends above the rotating hole 101, thereby changing the overall length of the chopsticks. When the length of the chopsticks needs to be further increased, repeat the above steps to complete it. The adjustment is convenient and fast, and the adjustment range is large to adapt to the application of chopsticks in different scenarios.

[0032] like Figure 9 and Figure 10As shown, the limit mechanism 6 includes a fixed column 61 and a slider 62. The fixed column 61 is arranged at the bottom of the mounting hole 34. A sliding hole 611 and a through hole 612 are formed in the fixed column 61. The through hole 612 is located above the sliding hole 611 and the through hole 612 communicates with the sliding hole 611. The top of the through hole 612 is of a frustum-shaped structure, and the top of the fixed column 61 is of a spherical structure. The slider 62 is slidably arranged in the sliding hole 611. An installation groove 622 is formed at the bottom of the slider 62. A spring 63 is arranged between the installation groove 622 and the bottom of the sliding hole 611. A spherical groove 621 is formed at the top of the slider 62. A ball 64 is rollably arranged on the spherical groove 621. The top of the ball 64 extends to the outside of the fixed column 61, and the ball 64 can roll on the top of the through hole 612.

[0033] As Figures 3 to 7 As shown, a threaded hole 106 is formed at the center of the bottom of the chopstick body 1. A screw rod 21 is arranged at the top of the chopstick head 2. The screw rod 21 is threadedly connected in the threaded hole 106. A slot 107 is formed at the bottom of the chopstick body 1. A rubber ring 4 is embedded in the slot 107. A clamping head 5 is arranged at the top of the chopstick head 2. The structure of the clamping head 5 is a stepped shaft ring structure. The clamping head 5 is clamped in the slot 107 and the rubber ring 4 to prevent the chopstick head 2 from shaking during use and ensure stable connection.

[0034] The specific implementation method is as follows: the extension rod 3 is inserted into the placement hole 102 of the chopstick body 1 by rotating the head 35, and the two limiting mechanisms 6 are aligned with the two slide grooves 105 and then continued to be pressed down, so that the ball 64 rolls along the inner wall of the slide groove 105, and then the sliding part 33 slides into the placement hole 102. When the sliding part 33 slides to the bottom of the placement hole 102, the ball 64 is just at the same height as the groove 103 at the lower end. At this time, the rotating head 35 is rotated to make the ball 64 roll along the inner wall of the groove 103 until the ball 64 rolls into the limiting hole 104. The ball 64 extends into the limiting hole 104 under the action of the spring 63, and the extension rod 3 is limited and fixed in the chopstick body 1. When the overall length of the chopsticks needs to be adjusted, a certain force is applied to rotate the rotating head 35. Since there is a rounded corner at the end of the limiting hole 104, the ball 64 is subjected to force. When the ball 64 rolls to the inner wall of the slide groove 105, the rotating head 35 is pulled upward until the ball 64 contacts the inner wall of another groove 103. At this time, the rotating head 35 is rotated to make the ball 64 rotate along the inner wall of the groove 103 into the limiting hole 104, and the extension rod 3 is limited and fixed again. At this time, the upper end of the rotating part 31 extends above the rotating hole 101, thereby changing the overall length of the chopsticks. When the length of the chopsticks needs to be further increased, the above steps can be repeated. The adjustment is convenient and fast, and the adjustment range is large to adapt to the application of chopsticks in different scenarios. A screw 21 is set at the top of the chopstick head 2 and is threadedly connected to the chopstick body 1, which is convenient for disassembly and replacement of a new chopstick head. A rubber ring 4 and a clamp 5 are set to ensure the stability of the chopstick head 2 after installation to prevent the chopstick head 2 from shaking during use.

[0035] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
