[0025] The following will describe the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present disclosure, and are not used to limit the present disclosure.

[0026] In the present disclosure, unless otherwise stated, the orientation terms such as "left, right" are defined for facilitating the description of the drawing direction according to the corresponding drawings, and "inner, outer" are defined according to the contour of the corresponding components itself. The "end wall" refers to one side of the mouth of the crucible when the crucible is clamped in the clamping cavity, and the liquid in the crucible is poured out through the mouth. The "bottom wall" refers to the side away from the mouth of the crucible when the crucible is clamped in the clamping cavity. The terms such as "first, second" used in the present disclosure are used to distinguish one element from another, and do not have sequence and importance. In addition, when the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0027] Please refer to Figure 1 , a crucible tongs provided by an embodiment of the present disclosure includes a first clamping arm 110, a second clamping arm 120, and a limiting component 200. Among them, the second clamping arm 120 can be hinged to the first clamping arm 110. Both the first clamping arm 110 and the second clamping arm 120 can include a clamping part 111, and the two clamping parts 111 can enclose to form a clamping cavity 130 for clamping the crucible. The limiting component 200 can be arranged on the clamping part 111 to limit the crucible (not shown in the figure) in the clamping cavity 130. The limiting component 200 can be directly fixed on the clamping part 111, or the limiting component 200 can be connected to the clamping part 111 through male and female buckles, which is convenient for disassembly and replacement.

[0028] In the related art, in order to prevent the crucible from slipping out of the clamping cavity 130 during the process of pouring liquid through the mouth of the crucible, technicians will firmly clamp the crucible with the two clamping arms, which will cause clamping marks on the side wall of the crucible and affect the subsequent use of the crucible.

[0029] In this embodiment, the limiting component 200 is arranged on the clamping part 111. During the process of pouring the liquid in the crucible, the limiting component 200 can prevent the crucible from moving relative to the clamping cavity 130, avoiding the crucible slipping out of the clamping cavity 130 during the liquid pouring process, ensuring the stability and reliability of the operation of the crucible tongs, eliminating the need for technicians to clamp the crucible with excessive force, preventing the crucible from deforming, and also saving manpower, providing convenience for users.

[0030] In one embodiment, please refer to Figure 1 and Figure 2 , the limiting component 200 can be arranged on one of the two clamping parts 111. Combining Figure 2 with the drawing direction, for example, the limiting component 200 can be arranged on the right clamping part 111. When the crucible is clamped in the clamping cavity 130 and the technician drives the crucible to tilt to the left without the limiting component 200 by using the crucible tongs, when the liquid in the crucible flows out through the left side wall of the crucible, the limiting component 200 can limit the right side wall of the crucible to prevent the crucible from slipping out of the clamping cavity 130.

[0031] In another embodiment, the number of the limiting components 200 can be two, and they are respectively arranged on the left and right clamping parts 111. If the crucible needs to pour the liquid to the left, the limiting component 200 on the left clamping part 111 can be located near the right clamping part 111 of the left clamping part 111 to prevent the liquid from adhering to the left limiting component 200 when pouring the liquid, ensuring the stability of the operation of the left limiting component 200.

[0032] In one embodiment, combining Figure 1 , the limiting component 200 can include a limiting member 210 and a connecting member 220. One end of the connecting member 220 can be arranged on the clamping part 111, and the other end can extend in the first direction to be used for fitting against the side wall of the crucible. One end of the limiting member 210 can be connected to the connecting member 220, and the other end can extend in the second direction to be used for abutting against the end wall of the crucible. The first direction is the extending direction of the side wall of the crucible when it is clamped in the clamping cavity 130, and the second direction is the extending direction of the end wall (i.e., the bottom wall) of the crucible when it is clamped in the clamping cavity 130. The limiting member 210 can abut against the end wall of the crucible to prevent the crucible from slipping out of the clamping cavity 130 along the first direction during the liquid pouring process.

[0033] Combining Figure 1 , when the limiting component 200 is arranged on the right clamping part 111, when the technician pours the liquid to the left, the limiting member 210 can abut against the right end wall of the crucible to limit the crucible from sliding down along the first direction, eliminating the need for the technician to clamp the crucible with force and preventing the crucible from deforming due to excessive clamping force, facilitating the clamping by the technician.

[0034] Further, the limiting member 210 can be configured to be mounted on the connecting member 220 in a position-adjustable manner along the second direction, and / or the limiting member 210 can be configured to be mounted on the connecting member 220 in a position-adjustable manner along the first direction, ensuring that the limiting assembly 200 can adapt to crucibles of various sizes and improving the clamping and limiting range of the crucible tongs. For example, a plurality of limiting holes can be provided on the limiting member 210, and the plurality of limiting holes can be arranged at intervals along the second direction on the limiting member 210. Through holes can be provided on the connecting member 220. When it is necessary to limit a crucible with a smaller size, at this time, the limiting member 210 can move away from the connecting member 220, so that one end of the limiting member 210 can be close to the end wall of the small crucible. The limiting member 210 and the connecting member 220 are fixed by bolts passing through the through holes and the limiting holes corresponding to the positions of the through holes.

[0035] In another embodiment, the bottom wall of the crucible extends circumferentially, and the limiting assembly 200 is a plurality of straight rods. One end of the straight rod is arranged at the bottom of the clamping portion 111, and the other end extends along the first direction so as to be able to abut against the extending portion of the bottom wall of the crucible, preventing the bottom wall of the crucible from sliding downward along the first direction during the tilting process, thereby preventing the crucible from sliding down.

[0036] In one embodiment, the inner side of the clamping portion 111 can be configured as an inclined wall to match the outer wall of the crucible. By increasing the contact area between the clamping portion 111 and the crucible, it can be ensured that the side wall of the crucible can be uniformly stressed, avoiding deformation of the crucible. Further, the clamping portion 111 is made of a plate, so that the contact area between the clamping portion 111 and the crucible is large, and the pressure received by the crucible is small.

[0037] Further, the inner side of the clamping portion 111 is configured as an arc shape to match the outer wall of the crucible. By increasing the contact area between the clamping portion 111 and the crucible, it can be ensured that the side wall of the crucible can be uniformly stressed, avoiding deformation of the crucible.

[0038] In one embodiment, please refer to Figure 1 and Figure 2 , the middle parts of the first clamping arm 110 and the second clamping arm 120 can be hinged. Two clamping portions 111 can be respectively formed at the first ends of the first clamping arm 110 and the second clamping arm 120. Gripping portions 112 are formed at the second ends of the first clamping arm 110 and the second clamping arm 120. Driving the two gripping portions 112 to open enables the two clamping portions 111 to open. The crucible is placed in the clamping cavity 130. The limiting assembly 200 can be used to limit the crucible in the clamping cavity 130. Operating the gripping portions 112 to make the two clamping portions 111 approach each other enables the crucible to be limited in the clamping cavity 130. When the crucible is tilted to pour liquid to one side, the limiting assembly 200 can limit the movement of the crucible in the clamping cavity 130, avoiding the slipping of the crucible.

[0039] For example, in combination with Figure 1 , open the two clamping parts 111, abut the limiting part 210 against the right end wall of the crucible, close the two clamping parts 111, so that the crucible is clamped in the clamping cavity 130, operate the crucible tongs to drive the crucible to pour liquid, and the limiting part 210 will limit the right side wall of the crucible from sliding downwards, without the need for technicians to clamp the crucible with excessive force, avoiding deformation of the crucible.

[0040] In another embodiment, one end of the first clamping arm 110 and the second clamping arm 120 is hinged, and the technician holds the middle parts of the first clamping arm 110 and the second clamping arm 120 to control the opening and closing of the two clamping arms.

[0041] In one embodiment, please refer to Figure 2 , the inner side of the end of the clamping part 111 far from the holding part 112 can be configured as a flat section 1111, that is, the ends of the two clamping parts 111 far from the holding part 112 are bent outwards at the same time, making it difficult for the two clamping parts 111 to fit together, increasing the clamping volume of the clamping cavity 130, facilitating clamping of a larger crucible. When the two clamping parts 111 fit together, the contact area between them is large, avoiding the two clamping parts 111 from being squeezed and damaged.

[0042] In this embodiment, please refer to Figure 1 and Figure 2 , a heat insulation baffle 300 can be provided on the side of the holding part 112 close to the clamping part 111, avoiding liquid splashing onto the technician's hand during pouring, preventing the technician from being scalded, and at the same time, it can also block the heat radiation of the crucible, improving the comfort of the technician's operation.

[0043] In this embodiment, the holding part 112 can be wrapped with a heat insulation member, and the heat insulation member is a high-temperature resistant material, such as nickel-based alloy, cobalt-based alloy or iron-based alloy, etc. Through the heat insulation member, the heat conduction of the crucible can be reduced, avoiding the technician from being scalded. The plate size of the holding part 112 is large, facilitating the technician to hold.

[0044] In one embodiment, both the first clamping arm 110 and the second clamping arm 120 can be made of stainless steel material, and the stainless steel material has the advantages of wear resistance and corrosion resistance, ensuring the reliability of the use of the crucible tongs.

[0045] The preferred embodiments of the present disclosure have been described in detail above in combination with the accompanying drawings. However, the present disclosure is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0046] In addition, it should be noted that, in the above specific embodiments, the various specific technical features described can be combined in any appropriate manner without conflict. To avoid unnecessary repetition, the present disclosure will not separately describe various possible combinations.

[0047] In addition, any combination can be made between various different embodiments of the present disclosure, as long as it does not violate the idea of the present disclosure, and it should also be regarded as the content disclosed by the present disclosure.
