Clear up and use crucible tongs

(A) technical field

The utility model relates to a device for testing, in particular relates to a crucible for offsetting.

(B) background art

Crucible is a nickel-iron alloy or is made of stainless steel materials jawset, when the heating and digestion the need to heat the crucible or triangular flask is removed from the electric hot plate or electric furnace, the crucible must be used. The digestion was found in the practice of, in particular, when the digestion of the sample more, arranged and relatively dense and suddenly when carbonizing, the original structure of the crucible used for rear the pliers clamp take the object, often touch the adjacent digestion vessel, or even its overturning, can not rapidly taken off the object in a timely manner, sometimes the cover or the watch glass is removed first, then the container below. Because the clamping not timely enough, or carbide is easy to cause damage of the sample, so that to naught.

(C) the content of the invention

The utility model in order to compensate for the defects of the prior art, provides a simple structure, convenient use of the crucible for offsetting.

The utility model is realized through the following technical scheme:

A crucible for offsetting, including through the bottom of the two handles are hinged together, characterized in that the wrench handle including fore-stockaxis stock and the shaft, the shaft for hangs the straight handlefore-stock the front end of the, vertical the front suddenly handle , and threaded, the shaft of the vertical handle fore-stock vertical, the vertical the front suddenly handle and vertical haft vertical, the vertical the front suddenly handle , and cap are located in the same one plane, and the radian of the arc-shaped part is matched with radian of the crucible.

The inner side of the jaw is provided with an anti-skid pattern.

The beneficial effect of the utility model is:

1, the original straight -like two bent and through the crucible to open with a certain radian, is more favorable for the digestion of the specimen, digestion of clamping, the target object is not easy to fall off.

2, frame is arranged on the inner side of the jaw, clamping of the cover more conducive to the crucible.

Combined with the Figure below the utility model further note:

Figure 1 is the front view structure diagram of the of the present utility model;

Figure 2 is the over-looking structure diagram of the of the present utility model;

Figure 3 is the structure diagram of skid pliers jaws.

In the Figure, 1 shaft fore-stock , 2 axis stock , 3 hangs the straight handle , 4 the front vertically suddenly handle , 5 threaded, 6 jaw, 7-skid, 8 forcep shaft.

(E) specific embodiment

The utility model to the specific embodiment. As shown in Figure 1, Figure 2, Figure 3 shows, the crucible for offsetting, including through the bottom 8 of the two handles are hinged together, each clamp handle including axis stock 2 and axis fore-stock 1, handle in front of the shaft 1 is perpendicular to the front end of the shank 3, vertical the front suddenly handle 4, arc-shaped part 5 and the jaw 6, handle in front of the shaft 1 and the vertical handgrip 3 vertical, vertical the front suddenly handle 4 and the vertical handgrip 3 vertical, handle in front of the shaft 1 and the vertical the front suddenly handle 4 parallel, vertical the front suddenly handle 4, arc-shaped part 5 and the jaw 6 is located in a same plane, the arc-shaped part 5 and the radian of phase with the radian of the crucible, the jaw 6 is provided with the inner side of the frame 7, as shown in Figure 3, frame 7 preferably with the jaw 6 is vertical to the plane of the, such convenient clip crucible cover.

When the digestion of the sample very many, when arranged and relatively intensive, the utility model of the jaw of the 6 open, fall down slowly from the upper part of the crucible, the jaw 6 and the clamp to two sides of the crucible, at this moment axis stock 2 and axis fore-stock 1 is still located in the upper part of the other crucible, the crucible will not affect the other, gradually lifting the the utility model can be.

In addition to the technical characteristic specification, the remaining technical characteristics are the technicians of this field already known technology.
