[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] Please see Figures 1 to 2The fixture for rapidly processing multiple round needles according to an embodiment of the present invention includes: a base 1, wherein the base 1 has first sliding grooves 11 on both sides, a second sliding groove 12 in the middle of the base 1, and a third sliding groove 13 in the base 1 opposite to the second sliding groove 12; a length adjustment device 2, including a slider 21 and a locking block 22, wherein the slider 21 is U-shaped, and sliding blocks 23 matching the first sliding grooves 11 are provided at both ends of the slider 21; the locking block 22 is slidably disposed in the third sliding groove 13; the locking block 22 passes through the second sliding groove 12 and the slider 21 sequentially through a threaded rod 24; and a clamping device 3, including a fixing plate 31 and a clamping plate 32, wherein the fixing plate 31 is fixedly disposed on the base 1, and the fixing plate 31 is provided with a plurality of fixing grooves 33, the groove direction of the fixing grooves 33 being consistent with the sliding direction of the slider 21; and the clamping plate 32 covering the fixing plate 31.

[0019] In the above embodiment, firstly, the base 1 serves as the supporting structure for the entire fixture, and the first slide grooves 11 on both sides are used to install and guide the slider 21 in the length adjustment device 2. The slider 21 is U-shaped, and the sliding blocks 23 at both ends match the first slide grooves 11 to ensure that the slider 21 can slide smoothly on the base 1 along the direction of the first slide grooves 11.

[0020] The length adjustment device 2 achieves length adjustment through the cooperation of the slider 21 and the locking block 22. During sliding, the slider 21 can adjust its position on the base 1 as needed. The locking block 22 is slidably disposed in the third groove 13 of the base 1, and passes through the second groove 12 and the slider 21 sequentially via a threaded rod 24. After the slider 21 is adjusted, the threaded rod 24 is rotated so that its end presses against the slider 21, thereby fixing the position of the slider 21 and achieving precise length adjustment.

[0021] The clamping device 3 is used to clamp the round needle. The fixing plate 31 is fixedly mounted on the base 1, and the fixing groove 33 on its surface is aligned with the sliding direction of the slider 21. The clamping plate 32 covers the fixing plate 31, forming a clamping space together with the fixing plate 31. When the round needle is placed between the fixing plate 31 and the clamping plate 32, the needle can be stably clamped by adjusting the position of the clamping plate 32 or applying pressure.

[0022] In use, firstly, the position of the slider 21 is adjusted using the length adjustment device 2 according to the length and quantity of the round needles to adapt to different processing requirements. Then, the round needles are placed in the clamping device 3, and the clamping plate 32 is adjusted to hold the round needles. Finally, the processing operation of the round needles can be performed. The entire fixture has a compact structure, is easy to operate, and can achieve rapid processing of multiple round needles.

[0023] Please see Figures 1 to 2In another embodiment, one end of the clamping plate 32 and one end of the fixing plate 31 are provided with threaded holes 4, and the other end of the clamping plate 32 is provided with a notch, so that the clamping plate 32 can swing relative to one end of the fixing plate 31.

[0024] In the above embodiment, threaded fixing pins are provided at both ends of the fixing plate 31. The threaded fixing pin on the left side passes through the clamping plate 32, so that the clamping plate 32 can swing circumferentially around the threaded fixing pin. When the notch on the clamping plate 32 swings to the threaded fixing pin on the right side, the threaded fixing pin on the right side is tightened, so that the clamping plate 32 is fixed to the fixing plate 31.

[0025] Please see Figures 1 to 2 In another embodiment, the fixing groove 33 is V-shaped.

[0026] In the above embodiments, the V-groove design provides better guidance and stability, ensuring that the clamping plate 32 remains on the correct path during sliding. Simultaneously, the shape of the V-groove can accommodate needles of different diameters, improving the versatility and flexibility of the clamping device 3 and meeting diverse processing needs.

[0027] Please see Figures 1 to 2 In another embodiment, the width of the second groove 12 is 3mm to 5mm wider than the width of the threaded rod 24.

[0028] In the above embodiment, this design ensures that the threaded rod 24 has sufficient room to move within the second slide groove 12, facilitating the smooth insertion of the threaded rod 24 and adjustment of the slider 21 position. Simultaneously, it also ensures that the threaded rod 24 will not damage the fixing groove 33 or the slider 21 due to excessive tightening during locking, thus improving the durability and reliability of the fixture.

[0029] Please see Figures 1 to 2 In another embodiment, both the first groove 11 and the sliding block 23 are trapezoidal.

[0030] The trapezoidal structure effectively prevents the sliding block 23 from accidentally falling out of the fixed groove 33, improving the structural stability and safety of the fixture. At the same time, the cooperation between the trapezoidal fixed groove 33 and the sliding block 23 provides better guidance, ensuring that the slider 21 remains stable during sliding, reducing shaking and noise.

[0031] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
