Specific embodiment
1. further to illustrate that the utility model is to reach technological means and the work(that predetermined purpose of utility model is taken
Effect, below in conjunction with attached drawing and preferred embodiment, to according to specific embodiment of the present utility model, structure, feature and its effect,
Detailed description are as follows：
A kind of high temperature-proof crucible tongs as shown in Figs. 1-2, including two handle rings 1, further include two handles and block cover 3, in order to just
In explanation, handle is included to be divided into clamping part 21, connecting portion 22, extension 23 and afterbody 24 successively from front end to rear end, below
This four parts are described respectively.
The clamping part 21 of handle includes arc shape board 211 and sharp plate 212 for clamping crucible, two arc shape boards 211 for from
The side gripping crucible of crucible, referring again to Fig. 3, since the side of crucible is arcuation, in order to accurately grip, arc shape board
Indent, i.e. the relative inner face of two arc shape boards 211 are harmonious to grip crucible from the top down in 211 relative inner face；In order to prevent
Crucible drops, and sets sharp plate 212 in the lower inside of arc shape board 211, the opposite face of two sharp plates 212 is arranged like the sword of blade
Item, convenient for " scooping up " crucible from the bottom surface of crucible, two in the figure sharp plates 212 that are harmonious just form a full circle, it is necessary to explanation
It is that two sharp plates 212 there may be gap；In order to increase radiating efficiency, in the plate face of the side of arc shape board 211 and sharp plate 212
