Description
Technical field
This utility model relates to a kind of use for laboratory clamping device, particularly relates to a kind of orient flexible Crucible tongs.
Background technology
Crucible tongs is a kind of common chemical apparatuses, is generally used for clamping crucible heating or taking, putting crucible in thermal source gas burner, electric furnace, Muffle furnace, alcohol burner, and during heating crucible, gripping crucible or crucible cover are used.It is mainly composed of rustless steel.At present, general Crucible tongs has long handle, has the jaw of a circular arc in the front end of long handle, Crucible tongs typically will use in the environment of extreme temperatures, operator is faced with work in hot environment, and when blow-on takes crucible, in-furnace temperature is high, operator must assure that and takes out crucible at short notice, the most not only high temperature furnace there is is infringement, owing to the operating time is long, operator is also brought along harm such as being burned, burn, this just requires that Crucible tongs must be easy to operate, and can take out rapidly clamping target.
Due to work in hot environment, operator must wear asbestos gloves, but asbestos gloves is the most excessive, does not mates with clamp handle size, operates highly inconvenient, and operator faces the overlong time of high-temperature region, thus increases the danger being burned, burning.
Summary of the invention
The purpose of this utility model is to provide and can orient flexible Crucible tongs more rapid stable clamping a kind of of crucible of high temperature.
For achieving the above object, the technical solution adopted in the utility model is: a kind of orient flexible Crucible tongs, including clamp handle, tong arm and jaw, it is characterized in that: be designed with guide slot in clamp handle, in clamp handle, lower end is provided with spring button, and spring button is provided with spring, spring upper end is fixedly connected with tong arm, tong arm top connects has jaw, tong arm bottom to be designed with stop button, and the lower external face of clamp handle is designed with high-temperature-resistant layer.
In this structure, described jaw includes arc chela.
In this structure, described jaw and described tong arm are for removably connecting.
In this structure, described high-temperature-resistant layer is asbestos layer or high temperature resistant enamelled coating.
In this structure, described tong arm upper end has screwed hole, and described jaw lower end is designed with stud, and stud is corresponding with screwed hole.
In this structure, the internal diameter of described jaw is 3cm, and external diameter is 1cm.
In this structure, the internal diameter of described jaw is 5cm, and external diameter is 3cm.
In this structure, the internal diameter of described jaw is 8cm, and external diameter is 5cm.
The utility model has the advantages of and be: due to this structure of the present utility model, corresponding jaw can be changed according to the overall dimensions of clamping heating utensil, operator can free-hand contact clamp handle, so using this utility model to facilitate clipping operation, it is possible at the clamping crucible that high temperature is the most more stable.

Detailed description of the invention
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings:
This utility model is as shown in Figure 1, 2, a kind of orient flexible Crucible tongs, including clamp handle 4, tong arm 2 and jaw 1, it is characterized in that: be designed with guide slot in clamp handle 4, in clamp handle 4, lower end is provided with spring button 6, and spring button 6 is provided with spring 5, spring 5 upper end is fixedly connected with tong arm 2, tong arm 2 top connects has jaw 1, tong arm 2 bottom to be designed with stop button 3, and the lower external face of clamp handle 4 is designed with high-temperature-resistant layer 7.In the present embodiment, described jaw 1 includes arc chela 8.In the present embodiment, described jaw 1 and described tong arm 2 are for removably connecting.In the present embodiment, described high-temperature-resistant layer is asbestos layer or high temperature resistant enamelled coating.In the present embodiment, described tong arm 2 upper end has screwed hole, and described jaw 1 lower end is designed with stud 9, and stud 9 is corresponding with screwed hole.In the present embodiment, the internal diameter 10 of described jaw is 3cm, and external diameter 11 is 1cm.In the present embodiment, the internal diameter 10 of described jaw is 5cm, and external diameter 11 is 3cm.In the present embodiment, the internal diameter 10 of described jaw is 8cm, and external diameter 11 is 5cm.
When using this utility model, start spring button and tong arm is stretched out by guide slot.
Arc chela 8 has radian, makes curved surface preferably to fit with crucible, and jaw has different sizes, in order to the crucible of folder different model.
Distance between two arc chela 8 upper ends is external diameter, and distance maximum between arc chela 8 is internal diameter.
This utility model clamps variously-shaped crucible at high temperature.
Embodiment described above is only to be described preferred implementation of the present utility model; not design of the present utility model and protection domain are defined; on the premise of without departing from this utility model design concept; various modification that in this area, the technical solution of the utility model is made by ordinary skill technical staff and improvement, all should fall into protection domain of the present utility model.
