Technical Field
The utility model relates to a holding pincers field especially relates to a holding pincers.
Background
At present, in a laboratory, people need to take test containers such as beakers, crucibles, cylindrical cups, triangular flasks and the like which are heated to high temperature for testing or analyzing samples frequently back and forth for many times. Especially when the chemical test is used for analyzing the batch samples, the batch samples are often firstly digested by strong acid on an electric hot plate, in order to ensure that the samples are heated uniformly in the digestion process, the placing positions of containers containing the samples must be changed frequently, and the containers need to be taken out to observe the digestion conditions of the samples, wherein the temperature of the containers is often up to 150-300 ℃ during digestion.
The material of holding pincers used in laboratory is all metal or wooden, because can use the strong acid in the experimentation, and the flue gas of strong acid can corrode holding pincers with the strong acid gel bead of digesting the container outer wall, and the sample that pollutes and digests in the container can fly into under the influence of the part that receives the corruption air current in the fume hood to digest, influences the accuracy of test analysis result. And clear up often can use beaker or crucible in the process, their outer wall is smooth, clear up the container and hold the in-process that the pincers were pressed from both sides with traditional thing very easy landing, and then the solution that disappears in the container splashes or is extravagant, endangers experiment operating personnel's safety, still extravagant experiment resource and time.

Further conduct the utility model discloses technical scheme's improvement, two the inboard of getting the portion of clamp is provided with the skid resistant course.
Further conduct the utility model discloses technical scheme's improvement, the skid resistant course is for setting up and pressing from both sides the recess or the bump or the screw thread of getting the inboard increase frictional force of portion.
Further as an improvement of the technical scheme of the utility model, the included angle range between the hand-held part and the supporting part is 45-135 degrees, and the included angle range between the supporting part and the clamping part is 45-135 degrees.
Further conduct the utility model discloses technical scheme's improvement, handheld portion and supporting part the supporting part is the arc with the junction of pressing from both sides between the portion of getting.
Further conduct the utility model discloses technical scheme's improvement, the tip of handheld portion is provided with the ring structure.
The utility model has the advantages that: this holding pincers, it includes two tong arms, two tong arms include handheld portion in proper order, supporting part and clamp are got the portion, two supporting parts are through round pin axle cross symmetric connection, it is concave arc to press from both sides the portion of getting, two concave arc centre grippings of getting the portion of getting are on test containers such as beaker, crucible, handheld portion and supporting part, the supporting part becomes the contained angle setting with pressing from both sides between the portion of getting, it has the polytetrafluoroethylene layer all to wrap up on two tong arms, thereby the position of having avoided holding pincers and test container contact contains the sample that awaits measuring in the sample container that receives the corruption pollution test container such as metallic element.
Drawings
The present invention will be further explained with reference to the accompanying drawings:
fig. 1 is a schematic view of the overall structure of the embodiment of the present invention.
Detailed Description
This section will describe in detail the embodiments of the present invention, preferred embodiments of the present invention are shown in the attached drawings, which are used to supplement the description of the text part of the specification with figures, so that one can intuitively and vividly understand each technical feature and the whole technical solution of the present invention, but they cannot be understood as the limitation of the protection scope of the present invention.
In the description of the present invention, it should be understood that the orientation or positional relationship indicated with respect to the orientation description, such as up, down, front, rear, left, right, etc., is based on the orientation or positional relationship shown in the drawings, and is only for convenience of description and simplification of description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
In the description of the present invention, a plurality of means are one or more, a plurality of means are two or more, and the terms greater than, less than, exceeding, etc. are understood as not including the number, and the terms greater than, less than, within, etc. are understood as including the number. If the first and second are described for the purpose of distinguishing technical features, they are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated or implicitly indicating the precedence of the technical features indicated.
