Abstract
The utility model discloses arc-shaped forceps for clamping a tubular utensil in a biological or medical experiment, which are used for solving the problem of frequent slip phenomenon during clamping of tubular plastic or a glass utensil in the biological or medical experiment or breakage of a tube wall caused by excessive force during unscrewing of a tube cover existing in the conventional forceps. The arc-shaped forceps comprise two forcep handles (1), wherein the root ends of the two forcep handles (1) are fixedly connected into a whole; the two forcep handles (1) are arranged in a V shape; the clamping end of each forcep handle (1) is provided with an arc-shaped chuck (2); the arc-shaped chuck (2) is fixedly connected with the forcep handle (1) into a whole; the inner wall of each arc-shaped chuck (2) is provided with a rubber layer (3); and the two arc-shaped chucks (2) are arranged opposite to each other. The arc-shaped forceps are used for clamping tubular glass or plastic utensils in the biological or medical experiment or unscrewing tube covers.
Description
Technical field
The utility model relates to a kind of tweezers, is specifically related to the arc tweezers of gripping tubulose vessel in a kind of biology or the medical experiment.
Background technology
At present employed tweezers mainly are two kinds of straight forceps and curved tweezers in biology or the medical experiment, can not be with hand directly contact or outward winding cell cryopreservation pipe or glass centrifuge tube in the operation of some experiment, need to use straight forceps or curved tweezer gripping or the pipe lid of outwarding winding, but because tube wall is smooth, slip phenomenon often appears in the process of the gripping or the pipe lid of outwarding winding, if yet gripping or the pipe lid outwarded winding will cause tube wall damaged even broken energetically, thereby cause the failure of an experiment, especially just cell cryopreservation pipe or the glass centrifuge tube that takes out in the refrigerating chamber, because process cryogenic freezing tube wall becomes fragile and is frangible, the gripping or the pipe of outwarding winding firmly will cause slippage when covering, exert oneself excessively will cause the tube wall breakage, thereby cause the failure of an experiment.
The utility model content
The utility model is in order to solve existing tweezers in gripping biology or medical experiment when tubular plastic or glassware, slip phenomenon often appears, the pipe of outwarding winding covers the excessive problem that causes the tube wall breakage of exerting oneself, and then proposes the arc tweezers of gripping tubulose vessel in a kind of biology or the medical experiment.
The utility model is to address the above problem the technical scheme of taking to be: the utility model comprises two tweezers handles, the root end of two tweezers handles is affixed to be integral, the setting that is in the shape of the letter V of two tweezers handles, the bare terminal end of each tweezers handle is provided with the arc chuck, described arc chuck and the tweezers handle is affixed is integral, the inwall of each arc chuck is provided with one deck rubber layer, and two arc chucks are oppositely arranged.
The beneficial effects of the utility model are: the utility model is when gripping tubular glass vessel, because the outer wall profile of arc chuck inner surface contour and tubular glass vessel likeness in form, therefore gripping tubular glass vessel that can be firm, rubber layer in the arc chuck has increased the frictional force of arc chuck and tube wall, and because rubber layer hardness is lower, effectively prevented the tube wall breakage, when the pipe of outwarding winding covers, saw-toothed projections energy inlay card on the rubber layer is in the groove in the pipe lid outside, made things convenient for outwarding winding of pipe lid, prevented simultaneously owing to the excessive tube wall disrepair phenomenon that causes of exerting oneself.
Description of drawings
Fig. 1 is a front view of the present utility model, and Fig. 2 is the cutaway view of the left view of Fig. 1, and Fig. 3 is the enlarged drawing of arc chuck.
The specific embodiment
The specific embodiment one: as Figure 1-3, the arc tweezers of gripping tubulose vessel comprise two tweezers handles 1 in described a kind of biology of present embodiment or the medical experiment, the root end of two tweezers handles 1 is affixed to be integral, the setting that is in the shape of the letter V of two tweezers handles 1, the bare terminal end of each tweezers handle 1 is provided with arc chuck 2, described arc chuck 2 and tweezers handle 1 affixed being integral, the inwall of each arc chuck 2 is provided with one deck rubber layer 3, and two arc chucks 2 are oppositely arranged.Present embodiment has guaranteed when gripping tubular glass vessel, because the outer wall profile of arc chuck inner surface contour and tubular glass vessel likeness in form, therefore gripping tubular glass vessel that can be firm, rubber layer in the arc chuck has increased the frictional force of arc chuck and tube wall, and, effectively prevented the tube wall breakage because rubber layer hardness is lower.
The specific embodiment two: as Figure 1-3, the rubber layer 3 of the arc tweezers of gripping tubulose vessel is provided with several saw-toothed projections 3-1 in described a kind of biology of present embodiment or the medical experiment.Present embodiment increases the frictional force of rubber layer 3 and tubular glass vessel outside tube wall, prevents to take place in the clamping process slip phenomenon, when the pipe of outwarding winding covers, and in the groove of saw-toothed projections 3-1 inlay card outside the pipe lid, the pipe lid of being convenient to outward winding.Other composition and annexation are identical with the specific embodiment one.
The specific embodiment three: as Figure 1-3, the tweezers handle 1 that the tweezers handle 1 of the arc tweezers of gripping tubulose vessel is made for stainless steel in described a kind of biology of present embodiment or the medical experiment.Present embodiment has guaranteed that the utility model can carry out autoclaving, is suitable for carrying out sterile working, and because the stainless steel good toughness, tweezers handle 1 uses not yielding for a long time or fractures, and has prolonged service life of the present utility model.Other composition and annexation are identical with the specific embodiment one.
The specific embodiment four: as Figure 1-3, the arc chuck 2 that the arc chuck 2 of the arc tweezers of gripping tubulose vessel is made for stainless steel in described a kind of biology of present embodiment or the medical experiment.Present embodiment has guaranteed that the utility model can carry out autoclaving, is suitable for carrying out sterile working, and because the stainless steel good toughness, arc chuck 2 uses not yielding for a long time or fractures, and has prolonged service life of the present utility model.Other composition and annexation are identical with the specific embodiment one.
The specific embodiment five: as Figure 1-3, the height L of several saw-toothed projections 3-1 of the arc tweezers of gripping tubulose vessel is 0.01mm ~ 0.1mm in described a kind of biology of present embodiment or the medical experiment.Present embodiment guaranteed in the process of pipe lid of outwarding winding, serration 3-1 can clamp in the groove in the pipe lid outside, increased the frictional force of rubber layer 3 with the pipe lid outside.Other composition and annexation are identical with the specific embodiment two.
