Abstract

The utility model discloses a Z-shaped holding forcep, which comprising left and right forcep bodies. The Z-shaped holding forcep is characterized in that: each forcep body comprises a hand holding part, a supporting rod and a holding part; the supporting rods of the left and right forcep bodies are connected through a forcep shaft; each holding part is of an arc shape or a lambda shape; the handholding parts, the supporting rods and the holding parts of the forcep bodies are of a Z-shape as a whole. Because each holding part of the Z-shaped holding forcep is of an arc shape or a lambda shape, the Z-shaped holding forcep can flexibly take various containers, such as copples, beakers, cylindrical cups and the like. Moreover, the Z-shaped holding forcep are of a Z-shape as the whole, thereby the Z-shaped holding forcep can flexibly stretch into from above to take any one of the cylindrical containers closely arranged one by one. The utility model is especially applicable for high-temperature digestion tests.

Description

Z type holding forceps

Technical field

The utility model relates to holding forceps, and especially a kind of Z type holding forceps can make things convenient for, safety, food containers such as test chamber such as gripping beaker, crucible, cylindrical cup and cylindrical tank, hemispherical jar securely.

Background technology

At present, all there are the instrument pincers in most of field, and as operating forceps, medicine bottle Kaifeng pincers, crucible tongs etc., its structure is all unified mutually with its function or performance, by its function of its structures shape.

Along with the continuous development of technology and improving constantly of people's life requirement, people have done multiple improvement to the instrument pincers: the thing of holding of the multi-functional holding forceps below of number of patent application 93233491 partly is divided into pole, pincers end arc and occlusal surface, pole is symmetrical internal hook shape tangent line arc with the front of pincers end arc, and the middle part of pole to occlusal surface expands into long and narrow ellipse (ovum) shape; The birth control device forceps of number of patent application 200620136134.7, has scale, length to be controlled at 65 to 70 millimeters, jaw head end draw-in groove is arranged jaw forearm lateral bending.

Processed food in micro-wave oven runs into through regular meeting and repeatedly to take food containers such as the cylindrical tank that has been heated to high temperature and hemispherical jar back and forth.

In the laboratory, people are in order to test or analytic sample also often will repeatedly be taken test chambers such as the beaker that has been heated to high temperature, crucible, cylindrical cup, triangular flask back and forth.Particularly carry out an experiment in chemistry when carrying out the batch sample analysis, often on electric hot plate, clear up sample in batches earlier with strong acid, in the digestion process for sample is heated evenly, also must often change the putting position of the container that fills sample, simultaneously also need to take out the container observation sample and clear up situation, when clearing up, vessel temp is often up to 150～300 ℃, use common crucible tongs can only be by row from front to back or left and right directions by gripping container outside to inside, directly gripping comes in the middle of the electric hot plate and the specimen cup of the inside, often is to put on one's gloves with hand to grasp.But, because high temperature, the specimen cup outer wall often hangs with excessive strong acid pearl, gloves meet the very fast charing perforation of sour pearl of high temperature, not only hindered skin but also may be starved of a kind of convenience, safety this moment because the charing chip be fallen into the accuracy that container influence the analysis of experiments result, can just stretch into the holding forceps of containers such as firm gripping crucible, beaker, cylindrical cup, triangular flask from container.

The utility model content

The purpose of this utility model is to provide the Z type holding forceps of food containers such as test chambers such as the flexible gripping crucible of a kind of energy, beaker, cylindrical cup, triangular flask and cylindrical tank, hemispherical jar.

The technical scheme that realizes the utility model purpose is as follows:

A kind of Z type holding forceps comprises left and right caliper, it is characterized in that: caliper comprises hand grip portion, pole successively and holds thing portion; The pole of left and right caliper links to each other by pincers axles, and the described thing portion of holding is arc or " Λ " shape, the hand grip portion of described caliper, pole and to hold thing portion Z-shaped on the whole.

Further, the hand grip portion of caliper is provided with finger ring.

Further, the hand grip portion of caliper and its pole angulation are 45 °～135 °, and the pole of caliper is held thing portion angulation with it be 45 °～135 °.

The hand grip portion of caliper and the junction of its pole be knuckle linearly, also can be curved.

The pole of caliper is held thing portion with it junction is knuckle linearly, also can be curved.

The beneficial effects of the utility model are as follows:

Because the thing portion of holding of Z type holding forceps is arc or " Λ " shape, therefore containers such as gripping crucible, beaker, cylindrical cup flexibly, because it is Z-shaped on the whole, for the cylindrical container that closely is emitted on together, can hold wherein any of the square from container gripping of pincers flexibly.The utility model is specially adapted to the high temperature of batch sample and clears up test.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further detailed description.

As shown in Figure 1, a kind of Z type holding forceps comprises that left and right caliper caliper comprises hand grip portion 1, pole 2 successively and holds thing portion 3; The pole 2 of left and right caliper links to each other by pincers axle 21, holds thing portion 3 and is arc, the hand grip portion of described caliper, pole and to hold thing portion Z-shaped on the whole.

Be arc owing to hold thing portion 3, therefore containers such as the flexible gripping crucible of energy, beaker, cylindrical cup, triangular flask.

As shown in Figure 2, the hand grip portion 1 of caliper also is provided with finger ring 11.It is to operate for more convenient one hand that hand grip portion 1 is established finger ring 11.

As shown in Figure 9, hold thing portion 3 and be " Λ " shape.Such two thing portions of holding that constitute in opposite directions are containers such as gripping crucible, beaker, cylindrical cup, triangular flask flexibly also.
