Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully below. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

It will be understood that when an element is referred to as being "secured 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 the like as used herein are for illustrative purposes only.

Referring to fig. 1 to 4, the forceps according to a preferred embodiment of the present invention includes a forceps handle 10, two forceps arms 20 connected to the forceps handle 10, and a forceps head 30 connected to the forceps arms 20; the two forceps arms 20 are oppositely arranged; the forceps heads 30 are connected to one end of the forceps arm 20 far away from the forceps handle 10, and the two forceps heads 30 are arranged at intervals; referring to fig. 4, the width of the forceps tip 30 gradually decreases from one end of the forceps arm 20 to a direction away from the forceps arm 20, referring to fig. 2, the thickness of the forceps tip 30 gradually decreases from one end of the forceps arm 20 to a direction away from the forceps arm 20, and the maximum thickness of the forceps tip 30 is less than or equal to one third of the thickness of the forceps arm 20; it should be noted that the width of the forceps head 30 is the width between two sides of the forceps head 30, the thickness of the forceps head 30 is the distance between the inner side of the forceps head 30 and the outer side of the forceps head 30, the thickness of the forceps arm 20 is the distance between the inner side of the forceps arm 20 and the outer side, the inner side of the forceps head 30 is the opposite surface of the two forceps heads 30, and the outer side of the forceps head 30 is the opposite surface of the two forceps heads 30; similarly, the inner side surface of the forceps arm 20 is the surface of the two forceps arms 20 facing each other, and the outer side surface of the forceps arm 20 is the surface of the two forceps arms 20 facing each other.

The inner side surface of the forceps head 30 is a clamping surface 31, namely when clamping an article, the clamping surface 31 is used for contacting the article, and two corners of the clamping surface 31 are provided with arc chamfers protruding outwards, so that when clamping the article, the article can be effectively prevented from being damaged by the corners of the clamping surface 31. Further, the surfaces of the clamping surface 31 and the arc-shaped chamfer are smooth surfaces, namely when the tweezers are machined, the surfaces of the clamping surface 31 and the arc-shaped chamfer are polished, so that the clamping of articles caused by the concave and convex points on the surfaces of the clamping surface 31 and the arc-shaped chamfer is prevented.

Referring to fig. 1 and 3, in the present embodiment, the forceps handle 10, the forceps arm 20 and the forceps head 30 are integrally formed; in one embodiment, the forceps handle 10 and the forceps arm 20 are integrally formed, and the forceps head 30 is detachably connected with the forceps arm 20, so that when the forceps head 30 is seriously worn in long-term use of the forceps, the forceps head 30 only needs to be detached to replace a new forceps head 30, the whole forceps does not need to be replaced, and the cost is saved. Specifically, a buckle hole is arranged at one end of the forceps arm 20 far away from the forceps handle 10, and a buckle hook is arranged at one end of the forceps head 30 and correspondingly buckled with the buckle hole; so that the clasp hook is pulled out of the clasp hole when the forceps head 30 needs to be disassembled.

The forceps handle 10 is arranged in a flat shape; in this embodiment, the inner side surface of the tweezer arm 20 and the inner side surface of the tweezer head 30 are located on the same plane, and in one embodiment, the outer side surface of the tweezer arm 20 is provided with anti-slip patterns, which include a plurality of raised strips arranged at intervals, and the anti-slip patterns are used for playing an anti-slip role to prevent the occurrence of slippage phenomenon when the tweezers are used to clamp an article. One end of the forceps arm 20 connected with the forceps head 30 is provided with a transition part 21, and the transition part 21 is inclined; the arrangement of the transition part 21 is beneficial to improving the strength of the connection between the forceps head 30 and the forceps arm 20, and preventing the forceps head 30 from breaking.

Referring to fig. 3 again, the width of the forceps arm 20 gradually decreases from the forceps handle 10 toward the forceps head 30, and it should be noted that the width of the forceps arm 20 is the width between the two sides of the forceps arm 20; the maximum width of the forceps head 30 is smaller than the minimum width of the forceps arm 20. Referring again to fig. 2 and 4, in the present embodiment, the end of the forceps head 30 away from the forceps arm 20 is a tapered portion 32, and in other embodiments, the end of the forceps head 30 away from the forceps arm 20 may also be a square portion or an arc portion.

The width of the tweezers heads 30 of the tweezers of the utility model is gradually reduced from one end of the tweezers arms 20 to the direction far away from the tweezers arms 20, therefore, when the tweezers are used for clamping fine objects, the clamping force of the tweezers heads 30 for clamping the objects is more concentrated, and the objects can be stably clamped; and the two corners of the clamping surface 31 are provided with arc chamfers protruding outwards, so that when small articles are clamped, the articles are effectively prevented from being damaged by the corners of the clamping surface 31, and the quality of the articles is effectively guaranteed.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
