[0002] The head of a conventional pair of tweezers is relatively sharp and the stress point is relatively concentrated. When sampling and clamping with a traditional pointed tweezer or round tweezer, it is often easy to damage the integrity of the organism. For example, the head or tail of a polychaete of the annelid is clamped off, or the limb segment of a crustacean of the arthropod is clamped off. These often cause great trouble for subsequent identification.
[0003] Secondly, when studying large benthic organisms, it is often necessary to sample large benthic organisms in various environments. The friction force of traditional tweezers is small after getting wet. After clamping with tweezers for a long time, it is easy for the tweezers to fall off. Content of the Utility Model
[0004] The purpose of the utility model is to solve the problem that the friction force of the tweezers is small after getting wet and it is easy for the tweezers to fall off after clamping with the tweezers for a long time as mentioned in the above background technique, and to provide a pair of tweezers which is conducive to clamping large benthic organisms.

One end of the tweezer body is slidably sleeved with a rubber sleeve head.
[0007] Preferably, the rubber sleeve head includes two parts, a front end and a rear end. The front end of the rubber sleeve head is triangular, and the front end of the rubber sleeve head is a rectangular extension with a certain area. The thickness of the rectangular extension is less than that of the triangle, and the thickness difference is 2 mm - 3 mm.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0023] Referring to Figure 1 , a pair of tweezers that is conducive to clamping large benthic organisms, including two tweezer bodies symmetrically arranged. One end of the two tweezer bodies is fixedly connected. The tweezer body includes an integrally arranged triangular head 1, a rectangular extension 2 after the triangle, a curved front arm 3, an anti-slip groove 4, equidistant vertical friction lines 5, a rear arm 6, and a tweezer handle 7;
[0024] In this embodiment, the curved front arm 3 is designed with an upward arc, and the opening between the two tweezer bodies is 20 mm - 25 mm. The distance between the lowest point of the anti-slip groove 4 and the highest point on the curved front arm 3 is 10 mm - 15 mm. The distance between the equidistant vertical friction lines 5 is 1.0 mm - 1.5 mm. The horizontal length of the rear arm 6 and the highest point on the curved front arm 3 is 20 mm - 25 mm;
[0025] In this embodiment, a rubber sleeve head 8 is slidably sleeved at one end of the tweezer body. The thickness of the triangle in the rubber sleeve head 8 is 5 mm - 8 mm. The total length of the rubber sleeve head 8 is 20 mm - 25 mm. The rubber sleeve head 8 includes two parts, a front end and a rear end. The front end of the rubber sleeve head 8 is triangular. The front end of the rubber sleeve head 8 is a rectangular extension with a certain area. The thickness of the rectangular extension is less than the thickness of the triangle, and the thickness difference is 2 mm - 3 mm.
[0026] In this embodiment, as Figure 2 and 3 shown, this is the main part of the tweezer (without the rubber head sleeve). The curved design of the curved front arm 3 can make the head of the tweezer fit better during clamping. The curved front arm 3 is used to connect the tweezer head part and the holding part. The part behind the curved front arm 3 is the holding part. The arc-shaped depression of the hand and the holding part and the equidistant vertical friction lines 5 can fit; the rear arm 6 integrally connects the front part and the tweezer handle. The tweezer head part can be used to clamp items, or can be used to clamp items after installing the rubber sleeve head 8.
[0027] In this embodiment, as Figures 4 - 6 shown, the rubber sleeve head 8 can be connected to the tweezer body. After connection, press down the holding part with the hand. After the tweezer head is closed, as Figure 6As shown, the forceps body is made of stainless steel, which is inexpensive, corrosion-resistant, and has high strength. It is suitable for underwater operations and will not pollute the water quality. The triangular part in the front can easily pick up small polychaete annelids, small mollusks, etc., and the rectangular part in the back can increase the contact area with the organism when picking up larger organisms, thus facilitating picking. The rubber sleeve 8, due to its rubber material, often does not damage the object itself when picking up objects compared with traditional forceps. In this application, the forceps are not limited to picking up large benthic organisms, but can also be used to pick up hard objects, medical supplies, mechanical parts, and so on.
[0028] In this embodiment, the rubber sleeve 8 is divided into two parts. The front is triangular, and the back is a rectangular extension with a certain area. The rectangular part is a little thinner, and the thickness difference from the triangle is 2 mm - 3 mm. In this way, the integrity of the biological form can be better protected when picking up. The front arm bends upward with a certain arc. The distance between the lowest point of the concave arc of the hand-holding part and the highest point on the front arm is 10 mm - 15 mm. In this way, the picking part of the forceps head can better fit. The spacing of the vertical equidistant friction lines 5 in the hand-holding part is 1.0 mm - 1.5 mm, and the horizontal length of the hand-holding part is 20 mm - 25 mm. In this way, when using this forceps for operation, the forceps are not easily dropped from the hand. Finally, the front part of the rear arm is integrally connected to the forceps handle. This structure is novel and practical.
[0029] In this embodiment, after the front end of the forceps is equipped with the detachable rubber sleeve 8, when picking up organisms, compared with the sharp metal head of traditional forceps, the force application points are more uniform, and the rubber material better protects the integrity of the biological form; the curved design adopted by the forceps in the front arm is beneficial for the forceps head to better fit and is not easily dropped when picking up organisms.
[0030] In this embodiment, the hand-holding part of the forceps adopts an arc-shaped concave and is added with vertical equidistant friction lines, which enhances its anti-slip property and makes the forceps not easily dropped from the hand; the concave design of the hand-holding part enables the hand to better fit the forceps and enhances its controllability; the forceps body is made of stainless steel, which is inexpensive, corrosion-resistant, and has high strength and is suitable for underwater operations. The rubber sleeve is detachable and easy to clean.
[0031] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
