[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1

[0026] A medium frequency electric furnace fixture, such as Figure 1-Figure 3 As shown, it includes a medium frequency electric furnace 1 and a crucible 2 placed in the medium frequency electric furnace 1 for holding metal materials. After the metal materials are held in the crucible 2, they are placed in the medium frequency electric furnace 1 and melted by electromagnetic heating.

[0027] Among them, the edge of the crucible 2 is integrally formed with two groups of skirt plates 3, and also includes a rotating shaft 4. The outer wall surface of the rotating shaft 4 is sleeved with two groups of connecting rings 10 that can rotate around the rotating shaft 4. Two groups of first cross arms 5 are fixedly installed on the upper connecting ring 10 in a centrally symmetrical manner, and two groups of second cross arms 6 are fixedly installed on the lower connecting ring 10 in a centrally symmetrical manner. Clamp rods 7 are fixedly installed at the ends of the first cross arms 5 and the second cross arms 6. The lower part of the clamp rod 7 is circumferentially bent to form an upper plate 9. The two groups of upper plates 9 on the same side of the first cross arms 5 and the second cross arms 6 extend in opposite directions. The sum of the arc lengths of the two groups of upper plates 9 on the same side of the first arm 5 and the second arm 6 is less than the sum of the arc lengths between the two groups of skirt plates 3, that is, the two groups of upper plates 9 on the same side of the first arm 5 and the second arm 6 can slide down along the outer wall of the crucible 2 to under the skirt plate 3, and then rotate the first arm 5 and the second arm 6 to slide the upper plate 9 under the skirt plate 3 to clamp the skirt plate 3, and then pull the crucible 2 out of the medium frequency electric furnace 1, and through the cooperation of the four clamping rods 7 and the upper plate 9, the crucible 2 is stably clamped, and the first arm 5 and the second arm 6 are rotated at the same time, and the clamping is smooth and stable.

[0028] Furthermore, the first cross arm 5 and the second cross arm 6 are both arc-shaped rods, and the middle parts of the two groups of first cross arms 5 and second cross arms 6 on the same side are concave surfaces that are away from each other, which is convenient for users to hold.

[0029] Furthermore, in order to clamp more stably, a lower plate 8 is integrally formed at a position above the clamping rod 7 corresponding to the upper plate 9 , and the lower plate 8 overlaps with the upper plate 9 and the distance between the lower plate 8 and the upper plate 9 is the same as the thickness of the skirt plate 3 .

[0030] Furthermore, the outer diameter of the skirt plate 3 is the same as the inner diameter of the medium frequency electric furnace 1, and the bottom end surface of the skirt plate 3 is an inclined surface. When the crucible 2 is placed in the medium frequency electric furnace 1, the crucible 2 slides along the bottom end inclined surface of the skirt plate 3 into the center of the medium frequency electric furnace 1, thereby preventing the crucible 2 from deviating from the position in the medium frequency electric furnace 1 and affecting the heating efficiency.

[0031] Furthermore, the lower end of the end of the lower plate 8 is tilted upward to form a guide portion 11. When the clamping rod 7 is close to the skirt plate 3, the guide portion 11 can assist in smoothly clamping the skirt plate 3 between the lower plate 8 and the upper plate 9.

[0032] Furthermore, straight handles 12 are fixedly installed on the first cross arm 5 and the second cross arm 6 which are far away from each other. The straight handles 12 are vertically fixedly installed on the first cross arm 5 and the second cross arm 6. By holding the two sets of straight handles 12, the two sets of straight handles 12 are brought close to each other, so that the first cross arm 5 and the second cross arm 6 on the same side are separated, and an arc motion with the rotating shaft 4 as the center is made, driving the clamping rod 7 to clamp the skirt plate 3.

[0033] In this embodiment, the clamping rod 7 is extended into the gap between the two groups of skirt plates 3 until the upper plate 9 slides under the skirt plate 3, and then the two groups of straight handles 12 are brought close to each other by holding the straight handles 12, and then the first cross arm 5 and the second cross arm 6 are diverged, so that the two groups of clamping rods 7 and the upper plate 9 can be used to clamp the skirt plate 3. Through the cooperation of the four clamping rods 7 and the upper plate 9, the crucible 2 is stably clamped, and the first cross arm 5 and the second cross arm 6 are rotated at the same time, and the clamping is smooth and stable.

[0034] Embodiment 2:

[0035] A clamp in a medium frequency electric furnace 1, as shown in the rotating shaft 4 of the figure, is different from the embodiment 1 in that a bending handle 13 is fixedly installed on the first crossing arm 5 and the second crossing arm 6 which are far away from each other, and the bending handle 13 is horizontally bent at the top to form an L-shaped structure. The horizontal part of the bending handle 13 is sleeved with a ring 14 that can rotate around the bending handle 13. Through the bent bending handle 13, during the clamping process, the crucible 2 can be easily tilted sideways to pour out the molten metal liquid in the crucible 2.

[0036] In this embodiment, the crucible 2 can be easily tilted sideways during the clamping process by means of the bent handle 13 to pour out the molten metal in the crucible 2.

[0037] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
