Detailed ways

In order to facilitate the understanding of the present invention, a more comprehensive description of the present invention will be given below. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that a thorough and complete understanding of the present disclosure is provided.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which the present invention belongs. The terms used in the description of the present invention herein are only for the purpose of describing specific embodiments, and are not intended to limit the present invention.

It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" another element, there are no intervening elements present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for illustrative purposes only.

Please refer to FIG. 1 to FIG. 4 , which is a tweezers according to a preferred embodiment of the present invention, including a tweezer handle 10 , two tweezer arms 20 connected to the tweezer handle 10 , and a tweezer head 30 connected to the tweezer arms 20 ; the two tweezer arms 20 are oppositely arranged The tweezers head 30 is connected to the end of the tweezers arm 20 away from the tweezers handle 10, and the two tweezers heads 30 are relatively spaced apart; , please refer to FIG. 2, the thickness of the tweezers head 30 gradually decreases from one end of the tweezers arm 20 to the direction away from the tweezers arm 20, and the maximum thickness of the tweezers head 30 is less than or equal to one third of the thickness of the tweezers arm 20; need to be explained The width of the tweezer head 30 is the width between the two sides of the tweezer head 30, the thickness of the tweezer head 30 is the distance between the inner side of the tweezer head 30 and the outer side of the tweezer head 30, and the thickness of the tweezer arm 20 is the tweezer arm The distance between the inner side and the outer side of the 20, and the inner side of the tweezers head 30 is the face of the two tweezers heads 30, and the outer side of the tweezers head 30 is the opposite side of the two tweezers heads 30; similarly, and the tweezers The inner side of the arm 20 is the face of the two tweezers arms 20 facing each other, and the outer side of the tweezers arm 20 is the face of the two tweezers arms 20 that are opposite to each other.

The inner side of the tweezers head 30 is the clamping surface 31, that is, when clamping the object, the clamping surface 31 is used for contacting the object, and the two corners of the clamping surface 31 are provided with outwardly protruding arc-shaped chamfers, thereby When clamping an item, the edges and corners of the clamping surface 31 can effectively prevent the item from being pinched. Further, the clamping surface 31 and the surface of the arc-shaped chamfer are both smooth surfaces, that is, when the tweezers are processed, the clamping surface 31 and the surface of the arc-shaped chamfer are polished to prevent the clamping surface 31 and the arc-shaped chamfer. The surface of the chamfer has concave and convex points to pinch items.

Please refer to FIGS. 1 and 3 , in this embodiment, the tweezers handle 10 , the tweezers arm 20 and the tweezers head 30 are integrally formed; in one embodiment, the tweezers handle 10 and the tweezers arm 20 are integrally formed, the tweezers The head 30 is detachably connected to the tweezers arm 20, so that when the tweezers are severely worn during long-term use of the tweezers, it is only necessary to disassemble the tweezers head 30 and replace it with a new tweezers head 30, instead of replacing the entire tweezers, which is beneficial to saving cost. Specifically, one end of the tweezers arm 20 away from the tweezers handle 10 is provided with a button hole, and one end of the tweezers head 30 is provided with a buckle hook, and the buckle hook is correspondingly buckled with the button hole; out of the hole.

The tweezers handle 10 is a flat body; in this embodiment, the inner side of the tweezers arm 20 and the inner side of the tweezers head 30 are on the same plane, and in one embodiment, the outer side of the tweezers arm 20 is provided with anti-slip lines, The anti-slip pattern includes a plurality of protruding strips arranged at intervals, and the anti-slip pattern is used for anti-slip effect to prevent slippage when the tweezers are used to pick up the article. One end of the tweezers arm 20 connected with the tweezers head 30 has a transition portion 21, and the transitional portion 21 is inclined; the provision of the transitional portion 21 is beneficial to improve the strength of the connection between the tweezers head 30 and the tweezers arm 20, and prevent the tweezers head 30 from breaking.

Please refer to FIG. 3 again, the width of the tweezer arm 20 gradually decreases from the tweezer handle 10 to the tweezer head 30. It should be noted that the width of the tweezer arm 20 is the width between the two sides of the tweezer arm 20; the maximum width of the tweezer head 30 The width is smaller than the minimum width of the tweezer arms 20 . 2 and FIG. 4 again, in this embodiment, the end of the tweezers head 30 away from the tweezers arm 20 is a tapered portion 32, and in other embodiments, the end of the tweezers head 30 away from the tweezers arm 20 may also be a square portion or arc.

The width of the tweezers head 30 of the tweezers of the present invention gradually decreases from one end of the tweezers arm 20 to the direction away from the tweezers arm 20. Therefore, when the tweezers are used to pick up small objects, the tweezers head 30 is used to grip the objects. The force is more concentrated, so that the article can be clamped stably; and the two corners of the clamping surface 31 are provided with outwardly protruding arc-shaped chamfers, so as to effectively prevent the corners of the clamping surface 31 when clamping small articles. Pinch the item, that is, to effectively ensure the quality of the item.

The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity, all possible combinations of the technical features in the above-described embodiments are not described. However, as long as there is no contradiction between the combinations of these technical features, All should be regarded as the scope described in this specification.

The above-mentioned embodiments only represent several embodiments of the present utility model, and the descriptions thereof are specific and detailed, but should not be construed as a limitation on the scope of the utility model patent. It should be pointed out that for those of ordinary skill in the art, some modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent for this utility model shall be subject to the appended claims.
