Description

Technical Field

[0001] This utility model belongs to the field of hand tool technology, and in particular relates to a multifunctional needle threader. Background Technology

[0002] In the fields of garment making, such as hand knitting and sewing, threading, unthreading, and thimble stitching are essential steps. Currently, users typically need to use various tools or perform these operations by hand, which is cumbersome and inefficient.

[0003] In the prior art, there are some specialized tools that can simplify the above operations. For example, Chinese patent application number 202321877171.3 discloses a "double-headed thread puller," which has one end for threading and the other end for pulling, providing convenience to some extent. However, the functions of such tools are still relatively limited, usually integrating only two functions. When performing knitting operations, users may still need to prepare additional tools such as thread pullers or needle pullers, or perform needle pulling and other operations by hand, failing to fully achieve the integration and efficiency of the operation, thus causing inconvenience to users. Utility Model Content

[0004] To address the shortcomings of existing technologies, a multifunctional needle threader is provided.

[0005] This utility model is achieved by the following technical solution: a multifunctional needle threader, comprising:

[0006] A U-shaped housing, comprising a first housing and a second housing connected by a connecting portion;

[0007] The end of the first housing is provided with a lead wire assembly;

[0008] The end of the second housing is provided with a thread removal assembly or a storage compartment for hand sewing needles;

[0009] The first housing and the second housing are respectively provided with a first clamping part and a second clamping part on the opposite sidewalls located at the opening end of the U-shaped housing;

[0010] The first and second housings can approach each other under the action of external force, so that the first clamping part and the second clamping part work together to clamp the hand sewing needle.

[0011] Lead wire operation:

[0012] When it is necessary to thread a suture through the eye of a hand-sewing needle, the user holds the U-shaped housing with one hand. Then, the thread guide assembly with the suture is passed through the eye of the needle; next, the thread guide assembly hooks the suture, and then the U-shaped housing is moved, causing the thread guide assembly to detach from the eye of the needle, allowing the suture to pass through the eye of the hand-sewing needle. Finally, the suture is removed from the thread guide assembly, completing the threading process.

[0013] Needle removal procedure:

[0014] When it is necessary to remove a hand-sewing needle from the fabric, the user places the needle between the first clamping part of the first housing and the second clamping part of the second housing. Then, the user pinches the first and second housings together with their fingers, causing the first and second clamping parts to move closer together, thus firmly holding the needle. At this point, the user simply needs to pull the tool along the needle's axis to easily and safely pull the needle out of the fabric.

[0015] Suture removal procedure:

[0016] When it is necessary to remove the sutures, the user can do so using the suture removal component located in the second housing.

[0017] The U-shaped design of the aforementioned U-shaped housing enables the needle removal function. Furthermore, the first and second shells of the U-shaped housing are equipped with a thread guide assembly and a thread removal assembly, or a storage compartment for hand sewing needles, resulting in a more concise and compact structure. Integrating the three components—thread guide, needle removal, and thread removal / needle storage—into a single unit can meet a wider range of user needs.

[0018] Preferably, the connecting part has a plurality of pin holes on the outer wall away from the first and second housings for pinning the hand sewing needle.

[0019] The above settings also add a pin function, thus enabling the entire needle threader to have four functions: threading, needle removal, thread unwinding, and pinning.

[0020] Preferably, the inner wall of the connecting part is formed with a contact surface adapted to the pressing of a human finger.

[0021] The above settings allow users to apply force by pressing the contact surface with their fingers when using the ejector pin. The contact surface can be either a flat surface or a curved surface.

[0022] Preferably, the connecting portion is integrally formed with the first housing and the second housing in an elastic manner.

[0023] The above method allows the first and second housings to approach each other under applied pressure, and automatically reset after the pressure is removed.

[0024] Preferably, the inner width of the connecting portion is greater than the gap width between the first housing and the second housing, and the inner width of the connecting portion is configured to allow a human finger to be inserted.

[0025] The fact that the inner width of the connecting part is greater than the gap width between the first and second shells ensures that the deformation energy of the U-shaped shell is more effectively transmitted to the first and second ends when pinching force is applied, driving the first and second clamping parts to move smoothly and powerfully towards each other. At the same time, the inner width of the connecting part needs to be wide enough to allow a human finger to be inserted, thereby realizing the pin operation.

[0026] Preferably, the connecting portion is hinged to the first housing and the second housing, respectively.

[0027] Preferably, the connecting portion includes a first connecting portion and a second connecting portion that are mutually plugged into each other;

[0028] The first connecting part is integrally formed with the first housing and is L-shaped;

[0029] The second connecting part is integrally formed with the second housing and is L-shaped.

[0030] The above method allows the first and second housings to be assembled together to form a U-shape via the first and second connecting parts. Both the first and second connecting parts are elastic, allowing the first and second housings to approach each other and thus enabling the needle removal function.

[0031] Preferably, the first housing has a first sliding member that slides with the first housing inside, and the outer side wall of the first housing has a clearance groove that extends through the inside and outside. The first sliding button passes through the clearance groove and is fixedly connected to the first sliding member.

[0032] The lead wire assembly is fixed to the first sliding member, so that the lead wire assembly can extend out of the first housing or retract into the first housing.

[0033] The above configuration allows users to extend or retract the lead assembly by sliding the first slider. When not in use, the lead assembly can be retracted into the first housing, thereby improving safety.

[0034] Preferably, the second housing has a second sliding member that slides with the second housing inside, and the outer side wall of the second housing has a clearance groove that extends through the inside and outside. The second sliding button passes through the clearance groove and is fixedly connected to the second sliding member.

[0035] The wire removal assembly is fixed to the second sliding member, so that the wire removal assembly can extend out of the second housing or retract into the second housing.

[0036] The above design allows users to extend or retract the detachment assembly by sliding the second slider. When not in use, the detachment assembly can be retracted into the second housing, thereby improving safety.

[0037] Preferably, both the first and second sliders are equipped with elastic elements, which apply an elastic force to the first and second sliders to cause the lead wire assembly and the wire disconnection assembly to retract into the first and second housings.

[0038] The above settings can improve safety by allowing the lead wire assembly and the disconnect assembly to automatically retract into the first and second housings in their natural state.

[0039] Compared with the prior art, the beneficial effects of this utility model are: through the above-mentioned arrangement, a needle threader can realize the functions of threading, unthreading, removing or retracting the needle, and thimble. In addition, the U-shaped shell with elastic recovery ability can optimize the structure and integrate the four components of threading, needle removal, unthreading or hand sewing needle storage compartment and thimble into one component.

Detailed Implementation

[0046] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0047] like Figure 1As shown, this embodiment discloses a multifunctional needle threader, which mainly includes a U-shaped housing 1. The U-shaped housing 1 includes a first housing 31 and a second housing 32 connected by a connecting part 2. The connecting part 2 is bent and integrally formed with the first housing 31 and the second housing 32, so that the whole structure is U-shaped. Because the overall structure is U-shaped and the connecting part 32 is made of elastic material, the first housing 31 and the second housing 32 can approach each other under an applied external force and return to their original position after the external force is removed. A first clamping part 51 and a second clamping part 52 are respectively provided on the opposite side walls at the ends of the first housing 31 and the second housing 32. The first clamping part 51 and the second clamping part 52 are made of stainless steel. When the first housing 31 and the second housing 32 approach each other, the first clamping part 51 and the second clamping part 52 work together to clamp the hand sewing needle, thereby allowing the needle to be pulled outward.

[0048] like Figure 1 and Figure 2 As shown, the outer wall of the connecting part 2, away from the first housing 31 and the second housing 32, is provided with a plurality of pin holes 21 for pinning a hand sewing needle. The inner wall of the connecting part 2 forms a contact surface adapted to the pressure of the fingertip of a human finger, and the inner width of the connecting part 2 is greater than the gap width between the first housing 31 and the second housing 32. The inner width of the connecting part 2 is D, where D≥1cm, so that a human finger can be inserted to apply force to the connecting part 2 and complete the pinning operation.

[0049] like Figures 2 to 5 As shown, the first housing 31 has a thread guide assembly 91 at one end, and the second housing 32 has a thread removal assembly 92 at one end. Both the thread guide assembly 91 and the thread removal assembly 92 are any existing components capable of guiding and removing thread from hand sewing needles, such as thread hooks and thread removal blades. Both the first housing 31 and the second housing 32 have through holes at their ends, allowing the thread guide assembly 91 and the thread removal assembly 92 to be telescopically connected to the first housing 31 and the second housing 32, respectively; that is, the thread guide assembly 91 and the thread removal assembly 92 can extend to the outside of the housing and retract to the inside of the housing.

[0050] The first housing 31 has a first sliding member 61 that slides within it, and the first sliding member 61 slides along the length of the first housing 31. The outer wall of the first housing 31 has a through-groove groove 8, through which a first sliding button 41 passes and is fixedly connected to the first sliding member 61. A lead wire assembly 91 is fixed to the end of the first sliding member 61, allowing the lead wire assembly 91 to extend outside or retract inside the first housing 31 by moving the first sliding button 41. The first sliding member 61 is cylindrical, and an elastic member 7, which is a spring, is fitted on its outer side. The elastic member 7 applies an elastic force to the first sliding member 61, causing the lead wire assembly 91 to retract into the first housing 31.

[0051] The second housing 32 has a second sliding member 62 that slides within it, and the second sliding member 62 slides along the length of the second housing 32. The outer wall of the second housing 32 also has a through-groove 8, through which the second sliding button 42 passes and is fixedly connected to the second sliding member 62. The wire removal assembly 92 is fixed to the end of the second sliding member 62, allowing the wire removal assembly 92 to extend outside or retract inside the second housing 32 by moving the second sliding button 42. The second sliding member 62 is also cylindrical, and an elastic member 7, which is a spring, is fitted on its outer side. The elastic member 7 applies an elastic force to the second sliding member 62, causing the wire removal assembly 92 to retract into the second housing 32.

[0052] Lead wire operation:

[0053] When it is necessary to insert thread into the eye of a hand sewing needle, the user grasps the U-shaped housing 1. Then, the user pushes the first sliding button 41 with their finger, causing the thread guide assembly 91 to extend and pass through the eye of the hand sewing needle; next, the thread guide assembly 91 hooks the thread, and then the user releases the first sliding button 41. Under the action of the elastic element 7, the thread guide assembly 91 retracts, causing the thread guide assembly 91 to exit from the eye of the hand sewing needle; finally, the thread is detached from the thread guide assembly, thus completing the entire threading process.

[0054] Suture removal procedure:

[0055] When it is necessary to remove the sutures, the user grasps the U-shaped housing 1. Then, the user pushes the second sliding button 42 with their finger to extend the suture removal component 92 and perform the suture removal operation.

[0056] Needle removal procedure:

[0057] When it is necessary to remove a hand sewing needle from the fabric, the user places the needle between the first clamping part 51 of the first housing 31 and the second clamping part 52 of the second housing 32. Then, the user pinches the first housing 31 and the second housing 32 with their fingers, causing the U-shaped housing 1 to elastically deform, driving the first clamping part 51 and the second clamping part 52 to move closer together, thus firmly clamping the hand sewing needle. At this point, the user only needs to pull the tool along the axis of the hand sewing needle to easily and safely pull the needle out of the fabric.

[0058] In some other embodiments, a portion of the suture removal assembly 92 can be replaced with a storage compartment (not shown) for storing hand sewing needles. This storage compartment can be constructed using any existing needle storage compartment design.

[0059] In some other embodiments, the connecting portion 2 may also be hinged to the tail portions of the first housing 31 and the second housing 32, respectively. (Not shown in the figure)

[0060] Alternatively, the connecting part 2 includes a first connecting part and a second connecting part that interlock with each other; the first connecting part is integrally formed with the first housing and is L-shaped; the second connecting part is integrally formed with the second housing and is L-shaped. Both the first and second connecting parts are elastic, thereby allowing the first clamping part 51 and the second clamping part 52 to move closer together for needle removal. The fixing after interlocking can be achieved by a snap-fit, screw fixing, etc.
