Description

Technical Field

[0001] This utility model relates to a clamp mounting structure. Background Technology

[0002] On the market, needles with a diameter of 2.0mm or less do not have threads. They cannot be quickly disassembled or reassembled. The needle and handle are glued together. If the needle breaks, or if a different size hook needle is needed, a professional is required to carefully heat the joint between the needle tail and the handle to soften the glue, then use pliers to quickly pull the needle out.

[0003] Traditional methods are time-consuming and labor-intensive. Many crochet hook handles are made of wood, resin, or plastic, which can easily cause the handle to crack and become unusable during the baking process, resulting in significant waste. Moreover, micro crochet hooks with a tip smaller than 0.8mm are extremely prone to breakage during crocheting, making the replacement of hook tips a persistent problem.

[0004] Therefore, a clamp mounting structure is proposed to address the above problems. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figure 1-4As shown, a chuck mounting structure includes a needle bar clamping assembly and a wrench 11; a mounting hole 2 is opened at one end of the handle 1, the needle bar clamping assembly is disposed in the mounting hole 2, and the round rod 3 is mounted on the needle bar clamping assembly by the wrench 11. The round rod 3 can be a hook needle, but is not limited to a hook needle, and can also be a product such as a drill bit.

[0018] Specifically, the needle bar clamping assembly includes a threaded sleeve 4 and a spring-loaded chuck 5. The threaded sleeve 4 is disposed in the mounting hole 2. One end of the spring-loaded chuck 5 is threaded into the threaded sleeve 4, and the other end is connected to the spring-loaded chuck 5. A threaded hole 6 is formed in the middle of the threaded sleeve 4. One end of the spring-loaded chuck 5 is a threaded section 7, and the other end is a slotted chuck 8. The round rod 3 is inserted into the inside of the slotted chuck 8. A first inclined surface 9 is provided on the side of the slotted chuck 8 near the threaded sleeve 4, and a second inclined surface 10 is provided on the side of the threaded sleeve 4 near the spring-loaded chuck 5. The slotted chuck 8 clamps and fixes the round rod 3 by pressing the first inclined surface 9 through the second inclined surface 10. The threaded section 7 is threaded into the threaded hole 6.

[0019] Specifically, the slotted chuck 8 has multiple slots 12 evenly distributed around its circumference on the side facing away from the threaded sleeve 4; the wrench 11 has a through hole 13 in its middle, and multiple locking blocks 14 are evenly distributed around the inner wall of the through hole 13. The number of slots 12 is the same as the number of locking blocks 14, and one end of the locking block 14 protrudes to the side wall of the wrench 11. (Refer to...) Figure 2 , Figure 2 The example shows three. During installation, it can extend into the mounting hole 2, allowing the spring clamp 5 to be fully screwed into the mounting hole 2.

[0020] Specifically, the outer wall of the threaded sleeve 4 is provided with multiple anti-slip grooves 15, which makes the threaded sleeve 4 more securely installed in the mounting hole 2.

[0021] Specifically, during installation, the tail of the round rod 3 is inserted into the inside of the slotted chuck 8, and the threaded section 7 of the other end of the slotted chuck 8 is inserted into the threaded hole 6 of the threaded sleeve 4. The locking block 14 of the wrench 11 is used to lock the slot 12 of the slotted chuck 8. Then, the wrench 11 is rotated to move the spring chuck 5 towards the inside of the threaded sleeve 4. When the first inclined surface 9 of the slotted chuck 8 contacts the second inclined surface 10 of the threaded sleeve 4, the spring chuck 5 is rotated again, so that the second inclined surface 10 presses against the first inclined surface 9, causing the slotted chuck 8 to retract and clamp the round rod 3 on the inside, thus completing the installation of the round rod 3. To disassemble, the spring chuck 5 is rotated in the opposite direction by the wrench 11.

[0022] Specifically, the surface of the round rod 3 is coated with a hardening coating, which is one of titanium nitride, titanium carbonitride, titanium aluminum nitride, diamond-like carbon, or diamond. This makes the needle surface smoother, significantly improving the needle's wear resistance, bending strength, and fracture strength, and greatly extending the needle's lifespan.

[0023] Specifically, the needle bar clamping component can be exposed on the end face of the handle or hidden inside the handle. The clamping component is not exposed, which allows for more freedom in the design of the handle shape, perfectly fitting the shape of the fingers to grip, so that the hand will not get tired even after long-term use.

[0024] This chuck mounting structure, by setting up a threaded sleeve 4 and a spring-loaded chuck 5, allows the spring-loaded chuck 5 to clamp the round rod 3 by using a wrench 11 to move the spring-loaded chuck 5 inward towards the threaded sleeve 4. Even a weak weaver can easily and quickly, securely and reliably disassemble and replace needles using a wrench, making it convenient to use.

[0025] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
