Description
Technical Field
The utility model relates to an experimental apparatus technical field especially relates to an arc clip.
Background
The tool for taking the cell sample in the small liquid nitrogen container does not have a tool which is definitely used in the current experimental operation, most laboratories use traditional long-handle tweezers and long-handle hemostatic forceps as tools, the tool is not specially used for clamping the low-temperature sample in the design, and the tool is inconvenient to use in the design of the appearance. When traditional long-handle tweezers and long-handle hemostatic forceps are clamped, the hands can be right above the opening of the liquid nitrogen container, so that the hands cannot completely avoid low-temperature nitrogen and risk of low-temperature frostbite is caused. Further, if the liquid nitrogen container is opaque, human eyes must observe the object through the container opening, so that the object is clamped by using the traditional long-handle forceps or long-handle hemostatic forceps, but the hands can block the vision of the human eyes and are not favorable for clamping the object. And when traditional long handle tweezers or long handle hemostatic forceps got the object, need press from both sides traditional long handle tweezers or long handle hemostatic forceps with the hand to it drops to avoid traditional long handle tweezers or long handle hemostatic forceps not hard up object that leads to, uses inconveniently.
Accordingly, the prior art is deficient and needs improvement.

Further, the included angle of the two ends of the first arc-shaped clamping rod is 120 degrees, and the included angle of the two ends of the second arc-shaped clamping rod is 120 degrees.
Further, the arc-shaped clamp further comprises: the rubber rings are respectively sleeved on the inner sides of the first finger ring and the second finger ring. The rubber ring can provide buffering for fingers and provide better use feeling.
Furthermore, the first barb strip and the second barb strip are both provided with a plurality of barbs. The plurality of barbs are arranged, so that objects with different sizes can be conveniently clamped.
By adopting the scheme, the utility model provides an arc-shaped clamp, which adopts the arc-shaped first arc-shaped clamping rod and the arc-shaped second arc-shaped clamping rod, after the arc-shaped first arc-shaped clamping rod and the arc-shaped second arc-shaped clamping rod extend into a liquid nitrogen container, the hand is not positioned right above the mouth of the liquid nitrogen container, so that low-temperature nitrogen can be completely avoided, and the risk of low-temperature frostbite is avoided; and meanwhile, the sight of human eyes cannot be blocked. Set up first barb strip and second barb strip, clip the object after, alright also keep the state of cliping the object under the condition of not using the finger to exert oneself, very big user's use of having made things convenient for.
