[0028] Embodiment:

[0029] Referring to the drawings Figure 1 and the drawings Figure 3 , the present embodiment provides a new type of tweezers, including tongs handle, tongs arm and tongs head;The tongs handle includes integrally formed and bendable V-shaped structure first handle part 1 and second handle part 2;The tongs arm includes first tongs arm 3 and second tongs arm 4, first tongs arm 3 is integrally connected at the end of first handle part 1, second tongs arm 4 is integrally connected at the end of second handle part 2;The tongs head includes first tongs head 5 and second tongs head 6, first tongs head 5 is integrally connected at the end of first tongs arm 3, second tongs head 6 is integrally connected at the end of second tongs arm 4. After the production of tweezers, only the tongs handle is bent into V type, which can be shaped and used, convenient operation, avoids the tedious production and assembly, and, compared with the assembly structure, the integrated structure has better elasticity, and the clamping is more convenient.

[0030] Referring to the drawings Figure 1 and the drawings Figure 2As shown, the connection between the first handle 1 and the second handle 2 includes a connecting rib 7, the thickness of which is less than the thickness of the structures on both sides. This facilitates bending of the connecting rib 7 and ensures elasticity between the first handle 1 and the second handle 2. The thickness of the connecting rib 7 is 0.7mm to 1.2mm. The thickness of the connecting rib 7 can be 0.7mm, 0.8mm, 1.0mm, or 1.2mm. See Appendix. Figure 3 and attached Figure 4 As shown, the connecting stiffener 7 forms an open ring structure 8 when bent. When the first handle 1 and the second handle 2 need to be clamped, the ring structure 8 here can not only better avoid displacement, but also prevent the material from forming concentrated stress at this point, thus achieving better springback.

[0031] See appendix Figure 2 As shown, the connecting stiffener 7 has a first arc-shaped groove 701 on the side near the first handle 1 and a second arc-shaped groove 702 on the side near the second handle 2. Both the first arc-shaped groove 701 and the second arc-shaped groove 702 are arc-shaped structures that bend in the bending direction, so that the connecting stiffener 7 can form an unclosed circular structure 8 after bending. The arc-shaped groove design allows for better forming. The thickness of the connecting section 703 between the first arc-shaped groove 701 and the second arc-shaped groove 702 before bending is greater than the thickness of the locations of the first arc-shaped groove 701 and the second arc-shaped groove 702, and the thickness of the connecting section 703 after bending is equal to the thickness of the first arc-shaped groove 701 and the second arc-shaped groove 702. This allows space for the thickness change caused by the bending and stretching of the connecting section 703, making the overall thickness of the connecting stiffener 7 more uniform after bending.

[0032] See appendix Figure 1 As shown, a first mounting ring 9 and a second mounting ring 10 are respectively provided on the inner side of the first handle 1 and the inner side of the second handle 2, and a return spring is provided between the first mounting ring 9 and the second mounting ring 10. Since the return spring is a later-installed component, its structure is not shown in the accompanying drawings. During installation, one end of the return spring is first connected to the first mounting ring 9, bent, and then the other end of the return spring is connected to the second mounting ring 10. The return spring allows the tweezers arm to spring back to its initial state after gripping, facilitating repeated gripping operations.

[0033] In some implementations, see Appendix Figure 1 As shown, ribs 11 are provided on the inner side of both the first handle 1 and the inner side of the second handle 2. The ribs 11 can improve the strength of the tweezer handle. The ribs 11 extend to the tweezer arm, which also improves the strength of the tweezer arm.

[0034] In some implementations, see Appendix Figure 3As shown, the inner and outer sides of the first handle 1 and the outer side of the second handle 2 are provided with anti-skid lines 12. The design of the anti-skid lines 12 can increase the friction between the first handle 1 and the second handle 2 and the hands.

[0035] In some embodiments, referring to the accompanying drawings Figure 1 and the accompanying drawings Figure 3 As shown, the inner side of the first forceps head 5 and the inner side of the second forceps head 6 are provided with tooth surfaces 13. The provision of the tooth surfaces 13 can increase the friction between the clamping surface and the article, so that the clamping is more firm and less likely to slip.

[0036] In some embodiments, the inner side of the first handle 1 is provided with a first guide block, the inner side of the second handle 2 is provided with a second guide block corresponding to the position of the first guide block, and the second guide block is provided with a guide clamping groove corresponding to the structure of the first guide block. When the first handle 1 and the second handle 2 are clamped and approached, the guide blocks enter the guide clamping groove. Through the cooperation of the guide structure between the first guide block and the second guide block, the accuracy of the approaching of the forceps handles to each other is improved, and the misalignment affecting the clamping is prevented.

[0037] The novel forceps designed in the utility model can be used after being bent into a V-shaped structure, which is convenient to operate and has good elasticity, and the clamping is more convenient. The connecting rib plate 7 in the form of an unsealed circular ring structure 8 after being bent is arranged, so that the concentrated stress of the material at the bending position is avoided, and the resilience can be better achieved. The problems of troublesome assembly and poor elasticity of the forceps are solved.

[0038] The above embodiments are only for illustrating the technical concept and characteristics of the utility model, and the purpose is to enable those skilled in the art to understand the content of the utility model and implement it, and it cannot limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit and essence of the utility model should be covered within the protection scope of the utility model.
