Description

Technical Field

[0001] The utility model relates to the technical field of handmade wool crochet hooks, in particular to a handmade wool crochet hook with a needle that is easy to replace. Background Art

[0002] Crochet hooks are essential tools for crocheting and come in a wide variety of sizes, ranging from 3.5mm to 0.75mm. Aluminum and plastic are the most common materials, with the most commonly used hook sizes ranging from 2.5mm to 19mm. The more specialized, slender hooks are known as Tunisian hooks, also known as Afghan hooks. The weaving technique is a blend of crochet and needlework. However, most currently available crochet hooks utilize an integrated design. When knitting yarns of varying diameters, multiple hook sizes often require purchase, increasing the cost of the hook rods that connect them and leading to material waste. Furthermore, most hooks lack protective structures. For example, if a hook accidentally falls from your hand onto the ground, it can bend or even break, significantly increasing costs and impacting subsequent knitting.

[0003] In the prior art, for example, announcement No. CN215209894U proposes a crochet hook. The technical solution disclosed in this invention is as follows: it comprises a grip rod, wherein a hook rod is inserted into the interior of the grip rod, a mounting groove is provided on the inner left side of the grip rod, and grooves are provided on the inner walls of both sides of the mounting groove, and a positioning assembly is fixedly connected to the interior of the groove. By providing the positioning assembly, the traditional integrated connection is improved, so that the hook rod and the grip rod can be disassembled and assembled. When replacing hook rods of different diameters, one side of the hook rod passes through the positioning ring and enters the interior of the mounting groove. After the hook rod is pressed against the limit plate, due to the fitting groove provided on one side of the hook rod, the spring drives the positioning plate to move inwardly under the reaction force of the spring, so that the positioning plate is fixed in the interior of the fitting groove, thereby completing the replacement and fixing of the hook rod, thereby avoiding the waste of grip rod material costs of purchasing crochet hooks of different sizes, and the crochet hook is easy to install and disassemble, easy to operate, flexible in use, and has better use effect than the traditional method.

[0004] However, when the needle of the crochet hook of the prior art is replaced, the crochet hook will squeeze the spring inside the handle and bend it, which not only makes it inconvenient to disassemble and assemble the needle, but also easily damages the spring, thereby affecting the service life of the crochet hook.

[0005] In order to solve the above problems, the present application proposes a handmade wool crochet hook with easy needle replacement. Utility Model Content
