Description

Technical Field

[0001] The utility model relates to the technical field of hand-knitting tools, in particular to a crochet hook with adjustable length. Background Art

[0002] Crochet is a tool used for knitting. The earliest crochet hooks were probably made without hooks, but with fingers. Therefore, no traces of artificial tools were left, making it difficult to verify its specific history. Later, curved crochet hooks appeared. In the early days, they were nailed to wooden handles, which is a more common needle shape. There are also more expensive crochet hooks made of materials such as silver, brass, steel or bone, with many patterns carved on the handles, which are used by the upper class. In the 21st century, the materials used for crochet knitting are more diverse, including fine embroidery thread, lace thread, thick plush thread, rope, etc. Different thicknesses produce different crochet effects; the stitches are also more diverse. People flexibly arrange and combine basic stitches to derive a variety of compound stitches.

[0003] The crochet hook is mainly composed of a hook head, a hook body and a handle. The working principle of the crochet hook is to use the hook head to pass through the eye or loop of the fabric, and then pull the hook thread back for weaving or sewing.

[0004] The length of existing crochet hooks cannot be freely adjusted, resulting in them taking up more space when stored and carried. In addition, crochet hooks of fixed length cannot adapt well to different knitting projects and the knitter's body posture. Therefore, a crochet hook with adjustable length is proposed to solve the above problems. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a crochet hook with adjustable length, aiming to improve the problem in the prior art that the crochet hook cannot be adjusted in length and cannot adapt to different knitting projects and the knitter's body posture.

[0030] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 and Figure 2 The present invention provides an embodiment of a length-adjustable crochet hook, comprising a connecting rod 1, a fixed shell 2 fixedly connected to the side of the connecting rod 1, a fixing assembly 3 provided inside the fixing shell 2, a hook body 4 slidably connected to the inside of the connecting rod 1, a quick-disassembly assembly 5 provided on the top of the hook body 4, and a grip assembly 6 provided on the bottom of the connecting rod 1; the fixing assembly 3 includes a slide bar 7, which is slidably connected to the inside of the fixing shell 2, a spring 8 provided on the outer periphery of the slide bar 7, and a baffle 9 fixedly connected to one end of the slide bar 7, which applies inward pressure to the slide bar 7 through the spring 8 and the baffle 9. An insertion rod 10 is fixedly connected to the top of the slide bar 7, and the movement of the insertion rod 10 is controlled by the slide bar 7.

[0032] Reference Figure 1 and Figure 3The quick disassembly assembly 5 includes a connecting shell 12, which is fixedly connected to the top of the hook body 4 and is used to protect the internal structure. A spring telescopic rod 13 is fixedly connected to the top of the hook body 4, and a back plate 14 is fixedly connected to the top of the spring telescopic rod 13. A hook head 15 is slidably connected to the inside of the connecting shell 12, and a clamping block 16 is fixedly connected to the side of the hook head 15. The hook head 15 is fixed in the connecting shell 12 through the spring telescopic rod 13 and the back plate 14. A slide groove 17 is provided inside the connecting shell 12, and the clamping block 16 is slidably connected to the inside of the slide groove 17. The cooperation between the clamping block 16 and the slide groove 17 determines the trajectory of the hook head 15 entering the connecting shell 12. A clamping slot 18 is provided inside the connecting shell 12, and the clamping block 16 and the clamping slot 18 are clamped together. The position of the hook head 15 is fixed by the clamping block 16 and the clamping slot 18.

[0033] Reference Figure 1-Figure 3 The side of the hook body 4 is provided with a plurality of slots 11, and the insertion rod 10 and the slots 11 are engaged with each other. By inserting the insertion rod 10 into the slots 11 at different positions, the length of the crochet hook can be changed. Two fixed shells 2 are provided on the side of the connecting rod 1, and the interiors of the two fixed shells 2 are provided with fixed components 3. The two fixed components 3 are used to maintain the position of the hook body 4. The holding component 6 includes a handle 19, and the handle 19 is fixedly connected to the outside of the connecting rod 1. The bottom of the connecting rod 1 is rotatably connected to an auxiliary plate 20. By holding the handle 19 and placing the auxiliary plate 20 in the tiger's mouth, the crochet hook can be held more stably. The handle 19 is made of rubber material to increase the stability of the crochet hook.

[0034] Working principle: Pull out the insertion rod 10, adjust the hook body 4 to the appropriate length, align it with the slot 11 at the current position, release the insertion rod 10, and with the cooperation of the spring 8 and the baffle 9, the slide rod 7 receives inward pressure, and moves the insertion rod 10 inward, inserts it into the slot, fixes the position of the hook body 4, and completes the length adjustment. When the hook head 15 needs to be replaced, squeeze and rotate the hook head 15, slide it out of the connecting shell 12, and slide the block 16 of the new hook head 15 into the connecting shell 12 through the counter-rotating slide slot 17, squeeze the back plate 14, and then rotate the hook head 15 to align the block 16 with the slot 18 and then let go. Under the action of the spring telescopic rod 13 and the back plate 14, pressure is applied to the block 16 to fix it in the slot 18, and the work of replacing the hook head 15 is completed.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
