Description

Technical Field

[0001] This utility model relates to the field of sewing tool technology, and in particular to a pair of tweezers for auxiliary sewing. Background Technology

[0002] In plush toy manufacturing, tweezers are considered an "extension of the fingertips," especially adept at solving two major challenges: "plush obstructing vision" and "operating in confined spaces." From installing facial features to filling with cotton, from plush finishing to safety inspection, tweezers are used throughout the entire process, serving as a behind-the-scenes hero in enhancing the toy's exquisiteness and safety.

[0003] In the manufacturing process of plush toys, such as the sewing of ears, two pieces of fabric, one side with plush and the other smooth, are sewn together. Because the ears are small and almost entirely rounded, it's impossible to use both hands steadily during manual sewing. Therefore, tweezers are almost always used for positioning. Pointed tweezers are used to hold the ear's pointed corners and curved edges, aligning them with the fabric's notch marks to ensure right-side-to-right alignment. However, during use, it's observed that workers need to use their index finger and thumb to grip and open the tweezers for extended periods. This step ensures the quality of the ear's processing and prevents workers from moving away from the moving needle, increasing operational safety. However, in practice, the following issues still arise:

[0004] 1. Because tweezers are small, the index finger and thumb may become concave, leaving marks and causing damage to the sewing worker's fingers. Novices may even experience bruising or bleeding around the area. Therefore, most operators now use a bandage to cover the area where the tweezers are used. While the bandage provides some protection, it also causes the area to remain closed for a long time, and the sweat can make the area uncomfortable.

[0005] 2. Prolonged use can reduce the clamping force, leading to insufficient clamping force, fabric detachment during sewing, or substandard quality after processing. Utility Model Content

[0006] In view of this, the present invention proposes a pair of tweezers for assisting sewing.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A sewing aid tweezers includes a tweezers body, which consists of two tweezer blades fixedly connected at their rear ends and open at their front ends. The front end of each tweezer blade is a gripping part, and the gripping part is provided with a magnetic attraction component for magnetically attracting the two gripping parts together. The tweezers body is also provided with an auxiliary opening and closing component for controlling the distance between the gripping parts.

[0009] As a further improvement to the above technical solution:

[0010] An optimized version of the above technical solution is that the magnetic suction assembly includes a magnet placed at the front end and located on opposite surfaces of the two tweezers, and a covering that surrounds the gripping part and the magnet.

[0011] An optimized version of the above technical solution is that the covering is a rubber sleeve.

[0012] An optimized version of the above technical solution is that the auxiliary opening and closing assembly includes an opening and closing roller located between the two tweezers, a limiting roller located on the opposite sides of the two tweezers, and both the opening and closing roller and the limiting roller are rotatably mounted on the connecting piece.

[0013] An optimized version of the above technical solution is that the diameter of the opening and closing roller is smaller than the gap between the two tweezers when the gripping part of the tweezers body is closed.

[0014] An optimized version of the above technical solution is that the sum of the shortest distances between the opening and closing rollers and the two limiting rollers is equal to the gap between the two tweezers when the gripping part of the tweezers body is closed.

[0015] An optimized version of the above technical solution is that an auxiliary push rod is provided on the connecting piece.

[0016] An optimized version of the above technical solution is that roller stripe friction grooves are provided on the opposite surfaces of the two tweezers.

[0017] An optimized version of the above technical solution is that the gripping portions on the opposing surfaces of the two tweezers are provided with gripping stripe friction grooves.

[0018] Compared with existing technologies, the beneficial effects of this utility model are:

[0019] (1) The tweezers provided by this utility model open and close by using an auxiliary opening and closing component, which reduces the need for finger force, significantly reduces the frequency and intensity of finger force, avoids skin indentation and soft tissue damage, and solves the problem of stuffiness and discomfort caused by bandage wrapping. At the same time, it uses a magnetic suction method to pick up the gripping part, further improving the clamping force. It also avoids the situation where the clamping force cannot meet the standard due to the assembly gap generated by the auxiliary opening and closing component, and avoids the situation where the clamping force is insufficient due to long-term manual operation. This ensures that the fabric is accurately aligned during the sewing process, especially the rounded edges and the cut marks, reducing the rework rate and improving the exquisiteness of the toy.

[0020] (2) The auxiliary opening and closing component and the magnetic suction component of this utility model are both added components, which makes it convenient to directly modify the tweezers used in the existing factory, thereby avoiding waste and saving the factory's modification costs.

[0021] (3) This utility model uses a rubber sleeve, which makes the magnet very stable by the restoring force of the rubber, and at the same time, the friction groove of the clamping part is squeezed out to achieve the fixing effect. The rubber sleeve also increases the friction of the clamping part, thereby improving the clamping force. The presence of rubber is also beneficial to protect the fabric.

[0022] (4) The opening and closing roller and the limiting roller designed in this utility model make it convenient for the operator to move back and forth to open and close the tweezers, and transform the pinching action of the fingers into rolling friction, thereby reducing the frequent opening and closing action of the fingers, reducing operator fatigue, and increasing the safe distance between the hand and the needle during sewing.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] like Figure 1 With appendix Figure 2 As shown, the main structure of this technical solution is a common tweezers body 1, which consists of two tweezer blades 11 fixedly connected at their rear ends and open at their front ends. At the front end of each tweezer blade 11 is a gripping part 111 (the gripping part 111 should form a certain angle with the central holding part to provide greater pressure and achieve the gripping purpose; in the attached figure, it is a straight line with a small angle). By pressing the opposite sides of the two tweezer blades 11, the distance between the two gripping parts 111 decreases, achieving the purpose of gripping the object. Considering the existing problems with tweezers in the sewing process of plush toys, this technical solution designs two components, specifically as follows:

[0031] One of them is a tweezers auxiliary opening and closing component used to replace manual finger pressing. The structure specifically consists of an opening and closing roller 5 in the middle position and limiting rollers 6 on both sides. The three rollers are rolled on the connecting piece 7 on both sides. In order to achieve the closing function of the gripping part 111 of the two tweezers 11, there are certain limitations on the size of the rollers, as follows:

[0032] 1. From the appendix Figure 3 As can be seen from the closed state of the tweezers, there is a certain gap between the opposing surfaces of the two tweezer blades 11 when the tweezers are closed. Therefore, the diameter of the opening and closing roller 5 in the middle position needs to be smaller than the minimum gap when the gripping part 111 at the front end of the tweezers body 1 is closed, and at most equal to. However, considering the actual error, it is best to choose less than.

[0033] 2. In order to achieve the closed state of the tweezers body when the tweezers auxiliary opening and closing component acts on the tweezers body, the distance between the two limiting rollers 6 should be equal to the gap between the two tweezers 11 when the gripping part 111 at the front end of the tweezers body 1 is closed, whether it is the maximum gap or the minimum gap.

[0034] Although the tweezers appear large in the schematic diagram in the attached figure, they are actually quite small. This is to make it easier for the operator to push them. Therefore, an auxiliary push rod 8 is installed on the connecting piece 7. Although it is located on the outside of the connecting piece 7 in the attached figure, it can also be provided at the top and bottom ends of the connecting piece 7.

[0035] Meanwhile, roller stripe friction grooves 9 are provided on the opposite surfaces of the two tweezers 11. They mainly serve two purposes: first, to increase the friction of the limiting roller to prevent rolling after closing, which would cause the gripping part 111 of the tweezers body 1 to open; second, to provide a gripping position and increase the friction at the gripping position.

[0036] Second, another part is the magnetic attraction part of the gripping part 111. Considering that the gripping is not performed by human force, and that the gripping part 111 may not be able to close completely due to the assembly gap of the tweezers auxiliary opening and closing parts, a magnet 2 is placed on the outer surface of the tweezers body 1. When the two magnetic attraction parts are close together, the two magnets 2 will attract each other within the movement gap of the tweezers auxiliary opening and closing parts, so that the two gripping parts 111 are tightly attached to each other, thereby achieving the function of clamping the item.

[0037] Meanwhile, a rubber sleeve 3 is placed on the clamping part 111 to fix the magnet 2. Secondly, in order to ensure stability during the clamping process, a clamping strip friction groove 4 is provided on the surface of the opposite side of the clamping part. The rubber sleeve 3 can wrap the clamping strip friction groove 4, so that it is squeezed out. On the basis of ensuring the friction of the clamping strip friction groove 4, the friction of the rubber further improves the friction on the plush fabric, and can also protect the surface of the plush fabric and avoid damage caused by excessive clamping force.

[0038] Other wrapping methods are also acceptable, such as straps, as long as they can achieve the basic function of fixing magnet 2.

[0039] Installation process of this utility model:

[0040] Since the two components of this technical solution are external components, there is no need to modify the existing tweezers body 1; only installation is required. This avoids replacing the existing tweezers body 1 in the factory, thus preventing waste and saving modification costs. Therefore, the installation process includes:

[0041] 1. Remove the connecting piece 7 on one side of the tweezers-assisted opening and closing component, push the tweezers 11 horizontally and insert it between the opening and closing roller 5 and the limiting roller 6, and then install the connecting piece 7 securely.

[0042] 2. Place the magnet 2 outside the clamping part 111, expand the rubber sleeve 3 to include the clamping part 111 and the magnet 2. After releasing, the rubber sleeve 3 tightly wraps the magnet 2 and the clamping part 111 under the action of elastic restoring force, which also causes the clamping strip friction groove 4 to be squeezed out.

[0043] The process of using this utility model:

[0044] 1. In the initial state, the tweezers auxiliary opening and closing component is located at the rear end of the tweezers body 1, and the tweezers body 1 is in the open / closed state;

[0045] 2. When it is necessary to clamp the plush fabric, align the clamping part 111 with the corresponding position, wrap the palm around the rear end of the tweezers body 1, and push it forward by the auxiliary push rod 8. As a result, due to the distance limit between the opening and closing roller 5 and the limiting roller 6, the gap between the two clamping parts 111 becomes smaller, reaching a near-closed state.

[0046] 3. Under the action of magnet 2, the gap between the clamping parts 111 is closed, thereby clamping the plush fabric;

[0047] 4. After completion, push the auxiliary push rod 8 backward. The force of the magnet 2 is canceled out by the pushing action, and the tweezers body 1 is pushed back to the initial position and opens.

[0048] 5. Repeat steps 2 to 4 to perform multiple clamping operations.

[0049] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
