Abstract

The utility model discloses multipurpose gripping pliers for gripping various beakers, conical flasks, and crucibles in control laboratories and laboratories. The multipurpose gripping pliers are characterized in that the shape of the gripping pliers is a V-shaped body; a small circular arc and a big circular arc are arranged on one section of the opening of the V-shaped body. The multipurpose gripping pliers can grip each type beaker, conical flask of 50 ml-800 ml, each type crucible and evaporating dish. The utility model has the advantages of high safety, simple structure and simple manufacture.

Description

Multipurpose gripping pliers

The utility model is the multipurpose clamping device that a kind of laboratory, laboratory are used, and is used for the various types of beakers of clamping, conical flask and crucible.

Existing laboratory, breadboard clamping device purposes are single, clamping beaker beaker tongs, this beaker tongs have two shortcomings: the one, and the beaker jaw is oversize, when a plurality of beakers heat on electric furnace together, use this beaker tongs to tend to run into or even knock other beakers, inconvenient operation over; The 2nd, this beaker tongs can not clamping 100 milliliters, 50 milliliters small beaker, therefore, the clamping small beaker is used another instrument--beaker clamp again.Clamping crucible crucible tongs, the clamping conical flask does not have specific purpose tool, uses the crucible tongs clamping more, but exist easily rock, unsafe problem.

Task of the present utility model provides the multipurpose gripper clamp of the various types of beakers of a kind of energy clamping, conical flask and crucible.

Task of the present utility model is to adopt the stalloy band to make one section of opening to have the V-type of big or small circular arc to clamp to finish.

Characteristics of the present utility model: the one, all types of beakers that the energy clamping is 50～800 milliliters; The 2nd, all types of conical flasks that the energy clamping is 50～500 milliliters; The 3rd, energy various types of crucibles of clamping and evaporating dish; Four are to use convenience, safety; The 5th, simple in structure, make easily.

Below in conjunction with accompanying drawing embodiment is described:

Accompanying drawing is these many front views with gripper clamp.

With reference to this gripper clamp of accompanying drawing be shaped as the V-arrangement body, on the opening one section (AB) of V-arrangement body, a little circular arc (R1) and an orthodrome (R2) are arranged, the V-arrangement body has a variable angle (BOB).This gripper clamp is with flexible thin steel band manufacturing, chrome-faced.

The use principle of this gripper clamp is: when taking gripper clamp firmly not hold with a firm grip with hand, included angle B OB is a maximum, the A end is dehisced also maximum, at this moment, little circular arc (R1) or orthodrome (R2) are enclosed within conical flask, small beaker or large beaker outside, the OB section of firmly holding with a firm grip then, angle (∠ BOB) is diminished, circular arc clamps conical flask or beaker, after putting down cup, bottle, loosen the OB section, under the elastic force effect, angle (∠ BOB) recovers maximum again, just can hold conical flask or beaker to be placed on Anywhere.With little circular arc (R1) but all types of Erlenmeyer flasks of 50 milliliters～500 milliliters of clampings and 50 milliliters～400 milliliters all types of beakers, with orthodrome (R2) but the beaker of 400 milliliters～800 milliliters of clampings.But with all types of crucible and the evaporating dishes of A end clamping.

Claims

1, the multipurpose gripper clamp of a kind of clamping beaker, conical flask and crucible, what it is characterized in that this gripper clamp is shaped as the V-arrangement body, on the opening one section (AB) of V-arrangement body a little circular arc (R1) and an orthodrome (R2) are arranged, the V-arrangement body has a variable angle (∠ BOB).
