Description
Technical field
The present invention relates to a kind of resolution pincers more particularly to a kind of resolutions heated in resolution experiment for graphite electric heating plate
Pincers, belong to technical field of experiment equipment.
Background technique
When testing, often cleared up using the heating that graphite electric heating plate carries out sample.Such as when surveying total soil nitrogen,
The heating that Erlenmeyer flask need to be used to carry out pedotheque on graphite heating plate is cleared up, and the temperature of graphite heating plate need to reach
300 degree of high temperature wants the conical flask that rocks of discontinuity, is on the one hand to make solid-like though graphite heating plate is placed in draught cupboard
Product are sufficiently reacted with solution (sulfuric acid), are on the other hand the color change for observing sample, the degree carried out so as to judgment experiment.When
When needing to handle compared with Multi-example, the limited area of graphite electric heating plate just seems more crowded, and when rocking, temperature is very high, heat-insulated
Gloves are often ruined and cause to be easy to knock over other samples, sample outflow, experiment when taking and placing triangular flask because gloves are too thick
Failure operates extremely inconvenient.And since graphite heating plate temperature is excessively high, when rocking multiple samples, required time is longer, hand
It can't stand and operating under high temperature environment for a long time.Sample when sometimes for using big graphite heating to clear up plate, close to the inside
Product bottle, which is not easily taken out, to be rocked and observes, and need to be careful, to prevent being scalded by graphite electric heating plate and being knocked over sample, and may
Acid burn skin in the sample outflowed.
Summary of the invention
The technical problem to be solved by the present invention is providing a kind of resolution heated in resolution experiment for graphite electric heating plate
Pincers, by the way that hinged grips pincers and adjustable clamp are arranged, conical flask can be clipped in the curved rod one and arc of grips pincers and adjustable clamp
Between bar two, rubber plays the role of anti-burn and anti-skid, the above-mentioned problem of effective solution.
The technical solution of the present invention is as follows: a kind of heat the resolution pincers in resolution experiment for graphite electric heating plate, it includes
Claw beam, fixed handle and movable handle, the claw beam are hollow rod-like structure, and fixed handle is fixedly connected on the top of claw beam, activity
Handle is located at the lower section of fixed handle and is hinged on the lateral wall of claw beam, end plate is fixedly connected in the bottom end of claw beam, in end plate
Bottom end is fixedly connected with grips pincers and pin shaft, is hinged with adjustable clamp in pin shaft bottom end, is connected between grips pincers and adjustable clamp
Spring is fixedly connected with tightrope on movable handle, and the cord hole that the other end of tightrope passes through on claw beam and grips pincers is connected to activity
The end of pincers.
The through-hole that tightrope passes through is equipped on the upper and lower part hand hay cutter wall of the claw beam.
The grips pincers are two sections of fixed rod-like structures, and it is arcuate structure curved rod that one section, which is another section of straight-bar structure,
One, cord hole is located at the end of straight bar section, the one layer of heat resistant rubber layer covered on the lateral wall of curved rod one.
The adjustable clamp is two sections of fixed rod-like structures, and it is arcuate structure curved rod that one section, which is another section of straight-bar structure,
Two, the one layer of heat resistant rubber layer covered on the lateral wall of curved rod two.
The beneficial effects of the present invention are: by the way that hinged grips pincers and adjustable clamp are arranged, conical flask can be clipped in grips pincers
Between the curved rod one and curved rod two of adjustable clamp, rubber plays the role of anti-burn and anti-skid, when not pressing from both sides conical flask, adjustable clamp and
Grips pincers are to open under the action of the spring, and at this moment very easily conical flask can be placed between adjustable clamp and grips pincers
Arc space in, be at this moment lifted up movable handle again, tightrope moves up, so that adjustable clamp and grips pincers be furthered
Conical flask is clamped, one layer of heat resistant rubber is cased in curved rod one and curved rod two, anti-scald and anti-skidding work can be played
With achieving good using effect.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention；
Fig. 2 is top view of the present invention.
Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below with reference to illustrate attached drawing will to the present invention make
It is described in further detail.
Embodiment 1: as shown in attached drawing 1~2, a kind of to heat the resolution pincers in resolution experiment for graphite electric heating plate, it is wrapped
Containing claw beam 4, fixed handle 1 and movable handle 2, the claw beam 4 is hollow rod-like structure, and fixed handle 1 is fixedly connected on claw beam 4
Top, movable handle 2 are located at the lower section of fixed handle 1 and are hinged on the lateral wall of claw beam 4, be fixedly connected in the bottom end of claw beam 4
End plate 5 is fixedly connected with grips pincers 6 and pin shaft 8 in the bottom end of end plate 5, adjustable clamp 7 is hinged in 8 bottom end of pin shaft, in grips pincers
