[0032] A crucible is used as a container for holding the material, and the stability of the crucible is poor. Therefore, a base 4 for supporting and limiting the holding container is provided in the heating chamber 3, and a slideway 41 for sliding a slide seat 5 is provided on the base 4. The slide seat 5 is slidably connected to the base 4, and a groove 52 for placing the holding container is provided on the slide seat 5. A limiting rod 8 for initially limiting the holding container is provided on the slide seat 5. With the cooperation of the groove 52 and the limiting rod 8, the crucible can be placed in the groove 52, and the crucible is initially pressed and limited by the limiting rod 8; the limiting rod 8 adopts a telescopic rod, including a pressing rod 81 and an inner rod 82, and the inner rod 82 is connected by The hinged seat 54 is rotatably connected to the sliding seat 5, and the pressure rod 81 is slidably connected to the inner rod 82. The pressure rod 81 is L-shaped and includes a sliding portion and a clamping portion. The sliding portion is provided with a sliding hole that matches the size of the pressure rod 81. The clamping portion is responsible for clamping and limiting the top edge of the crucible, and the pressure rod 81 is engaged with a bolt 83 for limiting the inner rod 82. The bolt 83 is arranged on the sliding portion, and the sliding portion is provided with a threaded hole engaged with the bolt 83. The threaded hole is connected to the sliding hole on the sliding portion to ensure that the end of the bolt 83 can contact the inner rod 82, so that the inner rod 82 and the pressure rod 81 can be limited by the bolt 83.

[0033] Slide blocks 51 are provided on the left and right sides of the slide seat 5, and the base 4 is also provided with slide rails 42 corresponding to the positions of the slide blocks 51. The length of the slide rails 42 is smaller than the length of the slide rails 41. The slide rails 42 and the slide blocks 51 are provided to enable the slide seat 5 to slide on the base 4 while avoiding excessive pulling force on the slide seat 5, resulting in complete separation of the slide seat 5 from the base 4, causing the crucible to fall and be damaged along with the slide seat 5.

[0034] A limiting mechanism is provided between the slide seat 5 and the base 4, and the limiting mechanism includes a sliding pin 9 and a pin hole 43. A limiting ring 53 is provided on the front side of the slide seat 5, and the limiting ring 53 is C-shaped. The slide pin 9 is slidably connected in the limiting ring 53. The base 4 is provided with the pin hole 43 corresponding to the position of the slide pin 9. The slide pin 9 can only slide in the vertical direction under the limitation of the limiting ring 53. When the bottom of the slide pin 9 is embedded in the pin hole 43, the slide seat 5 and the base 4 can be limited.

[0035] The front side of the slide seat 5 is also provided with a pin 55 for limiting the sliding pin 9. The pin 55 is located above the limiting ring 53. The sliding pin 9 is provided with a waist-shaped hole 91 for the pin 55 to slide. The waist-shaped hole 91 is provided so that when the slide seat 5 is pulled toward the furnace cover 2, the sliding pin 9 can be pulled upward first to separate it from the limiting ring 53, and then rotated 90 degrees around the pin 55 to make it in a horizontal state to avoid affecting the sliding of the slide seat 5; the sliding pin 9 and the base 4 are also provided with an inclined surface 92 for one-way limiting. The inclined surface 92 is provided so that when the slide seat 5 is pushed backward, the inclined surface 92 contacts with a group of pin holes 43, so that the sliding pin 9 can slide upward. When corresponding to the other group of pin holes 43, the sliding pin 9 is embedded in the pin holes 43 under the action of its own gravity, thereby realizing real-time limiting between the slide seat 5 and the base 4.

[0036] The base 4 is provided with a clamping mechanism for holding the container through the mounting seat 6, and the clamping mechanism corresponds to the position of the slide 5. The clamping mechanism includes a clamping jaw 7 and a rack 10, and a mounting groove 61 is provided on the facing surfaces of the mounting seat 6 and the slide 5, and a rotating shaft is rotatably connected in the mounting groove 61, and the clamping jaw 7 is installed on the rotating shaft. The clamping jaw 7 is provided with two groups and symmetrically arranged, and the mounting seat 6 is also slidably connected with the rack 10 for driving the two groups of the clamping jaws 7, and teeth are provided on the facing surfaces of the rack 10 and the clamping jaw 7. The rotating shaft is also provided with a gear 11 meshing with the rack 10, and the gear 11 is coaxially arranged with the rotating shaft. The mounting seat 6 is provided with a through hole for the rack 10 to slide, and the through hole is communicated with the mounting groove 61. End blocks are also provided on the front and rear end surfaces of the rack 10. The rack 10 is pushed by the sliding seat 5 to drive the container to be placed, thereby driving the clamping claw 7 to clamp and limit the container.

[0037] The working principle of the utility model is as follows: when in use, the staff opens the furnace cover 2, pushes the sliding pin 9 upward, makes the bottom of the sliding pin 9 slide out from the pin hole 43, releases the limit between the base 4 and the slide seat 5, and the sliding pin 9 is slidably connected with the limit ring 53. When the sliding pin 9 slides, the waist-shaped hole 91 and the pin 55 are slidably connected. When the pin 55 is located at the bottom of the waist-shaped hole 91, the sliding pin 9 is separated from the limit ring 53. At this time, the sliding pin 9 can be rotated to rotate around the pin 55, so that it can be rotated from a vertical state to a horizontal state.

[0038] The staff can pull the limiting ring 53 to make the slide seat 5 slide in the slideway 41, and the slider 51 slides in the slide rail 42. When the slider 51 slides to the front end of the slide rail 42, it cannot slide further. At this time, according to the height of the container, the height of the limiting rod 8 is adjusted, the bolt 83 is turned clockwise to release the limit between the pressure rod 81 and the inner rod 82, and the pressure rod 81 is slid upward to make the top of the pressure rod 81 higher than the height of the container. Then the staff places the container (crucible) in the groove 52, presses the pressure rod 81 downward to press it against the edge of the container, and turns the bolt 83 counterclockwise to limit the pressure rod 81 and the inner rod 82, so as to achieve the initial limit of the container and place the material to be heated in the container.

[0039] Push the slide 5 backward to reset it, rotate the slide pin 9 to make it in a vertical state and embed it in the limit ring 53, push the slide 5 backward, the inclined surface 92 on the slide pin 9 is released from the pin hole 43, due to the setting of the inclined surface 92, after contacting the inner wall of one group of pin holes 43, the inclined surface 92 is squeezed to drive the slide pin 9 to move upward, and when it moves to another group of pin holes 43, the slide pin 9 is embedded in the other group of pin holes 43 under the action of gravity. Under the action of the slide pin 9, the slide 5 and the base 4 are always in a limited state;

[0040] When the container contacts the rack 10, the slide 5 continues to be pushed, driving the container to squeeze the rack 10, driving the rack 10 to slide backward in the through hole of the mounting seat 6. Since the rack 10 has double teeth and meshes with the gear 11, the gear 11 is driven to rotate in the mounting groove 61, thereby driving the two sets of jaws 7 to rotate around the rotating shaft, clamping and limiting the container, and completing the feeding and limiting of the container.
