[0024] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "installed," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integrated connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances. Example 1
[0025] like Figure 1 Figure 2 The figure shows a practical and simple needle threader, comprising a handheld portion 1, one end of which is connected to a needle threading portion 2. The needle threading portion 2 comprises a needle threading arm 3, a thread feeder 4 (20 mm long), and a needle threading head 5 (10 mm long). The thread feeder 4 is a groove structure provided on the upper portion of the needle threading arm 3, and the needle threading head 5 is provided at the top of the needle threading arm 3. The groove is 1-3 mm long. The handheld portion 1 is a round plastic or stainless steel sheet with a diameter of 10-12 mm, which is convenient for holding. To facilitate the formation of the groove in the needle threading arm 3, the needle threading arm 3 should be made of iron or steel wire with a certain cross-section, such as a diameter of 0.5-0.7 mm.
[0026] When in use, you can first place the thread astride the groove and tighten it appropriately, then pass the needle threader 5 through the needle hole. After the groove of the thread feeder 4 also passes through the needle hole, the thread is clamped into the needle hole by the groove, and then remove the thread and exit the needle threader to complete the threading.
[0027] You can also pass the needle threader's needle head 5 through the needle hole and make the groove of the thread feed part 4 also pass through the needle hole, then place the thread astride the groove and tighten it appropriately, then pull the handheld part 1 in the opposite direction to make the thread feed part 4 and the needle threader 5 leave the needle hole, and the thread is clamped into the needle hole by the groove of the thread feed part 4, and the threading is successful.
[0028] In addition, the needle-threading portion 5 can be configured to have different sizes so as to be adaptable to needle holes of more sizes. The hand-held portion 1 can be configured to have other sizes or other shapes based on the principle of convenience. Example 2
[0029] like Figure 3 Figure 4 As shown, this embodiment differs from Example 1 in the structure of the thread feeder 4. This embodiment's thread feeder 4 (20 mm long) is an elastic ring connected between the needle threading arm 3 (5 mm long) and the needle threading head 5 (5 mm long). When passing through and exiting the needle hole, the elastic ring is compressed to allow for easy passage. Upon passing through the needle hole, it elastically recovers and expands the thread feeder hole, facilitating thread entry.
[0030] As a preferred embodiment of this embodiment, the elastic ring includes an upper bent portion 41 with a downward opening and a lower bent portion 42 with a downward opening. The ends of the upper bent portion 41 and the lower bent portion 42 are respectively connected to the needle threading arm 3 and the needle threading head 5. The upper bent portion 41 and the lower bent portion 42 are elastic steel wires. The upper bent portion 41 and the lower bent portion 42 are combined to form a diamond-shaped through hole for threading, which has better elasticity.
[0031] As a preferred embodiment of this embodiment, the needle threading arm 3 connected to the elastic ring includes an upper steel wire and a lower steel wire arranged in parallel, and the connected needle threading head 5 is a U-shaped steel wire; one end of the upper bend 41 is connected to the upper steel wire of the needle threading arm 3, and the other end is connected to the upper part of the U-shaped opening of the needle threading head 5; one end of the lower bend 42 is connected to the lower steel wire of the needle threading arm 3, and the other end is connected to the lower part of the U-shaped opening of the needle threading head 5. With this design, the upper bend 41 is more likely to tilt downward, and the lower bend 42 is more likely to tilt upward, which facilitates the thread feeder 4 to pass through the needle hole.
[0032] Furthermore, the folding positions of the upper bending portion 41 and the lower bending portion 42 form an angle of 150°.
[0033] When in use, the needle threader head 5 is passed through the needle hole. Under the restraining effect of the needle hole, the diamond-shaped through hole of the elastic ring is compressed and easily passes through the needle hole. After passing through, due to the loss of external force, the diamond-shaped through hole elastically recovers and expands, and the thread can easily pass through. Then, the hand-held part 1 is pulled in the reverse direction to withdraw the needle threader. The thread is clamped by the elastic ring and brought into the needle hole, and the threading is successful. Example 3
[0034] like Figure 5 Figure 6 As shown, this embodiment differs from Embodiments 1 and 2 in that the material and structure of the needle threader are changed. This embodiment provides a practical and simple needle threader, comprising a needle threading arm 3 (30 mm in length), one end of which is a needle threading head 5, and the other end of which is connected to a thread feeder 4, which is an elastic ring.
[0035] In a preferred embodiment of this embodiment, the needle threading arm 3 is a U-shaped steel wire, the closed end of which serves as the needle threading head 5. The upper portion of the open end of the U-shaped steel wire is connected to one end of an elastic ring, and the lower portion of the open end is connected to the other end of the elastic ring. The elastic ring is made of elastic nylon wire with a diameter of 0.2 mm.
[0036] When in use, before the needle threading arm 3 passes through the needle hole, the thread is passed through the elastic ring at the tail. After the entire needle threader passes through the needle hole, the thread is clamped and brought into the needle hole, and the threading is successful.
[0037] The needle threader described in the above embodiment can quickly thread soft, difficult to shape, rough and burred sewing thread into the needle hole. It is easy and efficient to operate, can greatly improve the efficiency of needle threading, and solves the problems of conventional needle threading difficulties and low efficiency. It is especially beneficial for people with poor eyesight.
[0038] The present invention is described in detail above through specific and preferred embodiments, but those skilled in the art should understand that the present invention is not limited to the embodiments described above. Any modifications, equivalent substitutions, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
