A lead screw is penetrated through one end of the cylinder. One end of the lead screw is fixedly installed with a plug. A jack is opened on the side surface of the support plate. One end of the lead screw is fixedly installed with a handle.

[0005] Preferably, the radius of the jack and the plug is the same, and the number of the support plates is two groups.

[0006] Preferably, relief grooves are opened on the surface of the disc, and the relief grooves are symmetrically distributed on the surface of the disc.

[0007] Preferably, the inner wall of the cylinder is provided with threads, and the threads are engaged with the lead screw.

[0008] Preferably, a diversion mechanism is provided on the top surface of the melting furnace. The diversion mechanism includes a vertical block fixedly installed on the top surface of the melting furnace. A rotating rod is rotatably connected to the inner side of the vertical block. A connecting block is fixedly installed on the surface of the rotating rod. A diversion plate is fixedly installed on the top surface of the connecting block.

[0013] Preferably, the bottom plate is made of austenitic stainless steel. Here, the service life of the bottom plate can be improved.

[0014] Compared with the prior art, the advantages and positive effects of the present invention are as follows.

[0015] 1. In the present invention, during actual use, when the staff needs to pour out the molten iron, they only need to rotate the handle. The handle then drives the disc to rotate. The disc then drives the rotating shaft to rotate. The rotating shaft can then drive the melting furnace to rotate. After the melting furnace is rotated to an inclined angle, the molten iron can flow out naturally. And the staff can also rotate the lead screw. At this time, since the inner wall of the cylinder is provided with threads, the lead screw moves in the cylinder at this time. The lead screw then drives the handle to move. At this time, the handle can be pulled out, so that the distance of the handle can be pulled far, enabling the staff to perform the rotation operation away from the melting furnace, reducing the probability of scalding, improving work efficiency. And when the handle is not in use, the lead screw can be retracted into the cylinder, which can reduce the occupied space of the handle and the lead screw. At the same time, after the lead screw is retracted into the cylinder, the lead screw can drive the insertion rod to insert into the insertion hole, which can limit the melting furnace at this time and prevent the melting furnace from tipping over, with high practicality.

[0016] 2. In the present invention, during actual use, when the melting furnace is rotated to an inclined angle and the molten iron flows out, the molten iron can fall on the deflector plate and finally flow out from the deflector plate. This can avoid the residue of molten iron on the top surface of the melting furnace. At the same time, the staff can also adjust the angle of the deflector plate according to the actual position where the molten iron needs to be poured out. When adjusting, only need to pull the pulling block, and then the limiting rod will be driven by the pulling block to leave the limiting hole. At this time, the deflector plate is released from the limit. Then the deflector plate can be rotated. After rotating the deflector plate to the required angle, release the pulling block. Subsequently, due to the pulling force of the tension spring, the tension spring pulls the pulling block, and then the pulling block drives the limiting rod to move until the limiting rod is inserted into the limiting hole. At this time, the deflector plate can be limited, improving the versatility.

[0017] 3. In the present invention, during actual use, the clamping plate provided can protect the melting furnace, prevent the melting furnace from tipping over, further ensure the stability of the melting furnace, and improve the safety. When it is necessary to tilt the melting furnace for feeding, only need to rotate the threaded rod. Then the threaded rod drives the moving plate to move. At this time, the moving plate slides in the through groove, and the moving plate then drives the clamping plate to move until the clamping plate is far away from the melting furnace. At this time, the limit can be released, and then the melting furnace can be tilted normally for feeding. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Please refer to Figure 1-7 , one end of the cylinder 6 is penetrated with a lead screw 7, the inner wall of the cylinder 6 is provided with threads, and the threads are engaged with the lead screw 7. One end of the lead screw 7 is fixedly installed with an insert rod 8, and the side of the support plate 1 is provided with an insertion hole 9. After the lead screw 7 is retracted into the cylinder 6, the lead screw 7 can drive the insert rod 8 to insert into the insertion hole 9. At this time, the furnace 3 can be limited. The radii of the insertion hole 9 and the insert rod 8 are the same. The number of support plates 1 is two groups. One end of the lead screw 7 is fixedly installed with a handle. Rotating the handle, the handle then drives the disc 5 to rotate, the disc 5 then drives the rotating shaft 2 to rotate, and the rotating shaft 2 can then drive the furnace 3 to rotate. After the furnace 3 is rotated to an inclined angle, the molten iron can flow out naturally, and the staff can also rotate the lead screw 7. At this time, since the inner wall of the cylinder 6 is provided with threads, the lead screw 7 moves in the cylinder 6 at this time, and the lead screw 7 then drives the handle to move. At this time, the handle can be pulled out, so that the distance of the handle can be pulled far, so that the staff can rotate the furnace 3 away, reducing the probability of scalding.

[0032] Embodiment 2

[0033] Please refer to Figure 3-6 Figure 3-6 , a diversion mechanism is provided on the top surface of the melting furnace 3. The diversion mechanism includes a vertical block 11, which is fixedly installed on the top surface of the melting furnace 3. A rotating rod 12 is rotatably connected to the inner side of the vertical block 11. A connecting block 13 is fixedly installed on the surface of the rotating rod 12, and a diversion plate 14 is fixedly installed on the top surface of the connecting block 13. When the melting furnace 3 is rotated to an inclined angle and the molten iron flows out, the molten iron can fall on the diversion plate 14 and finally flow out from the diversion plate 14. This can avoid the residue of molten iron on the top surface of the melting furnace 3. At the same time, the staff can also adjust the angle of the diversion plate 14 according to the actual position where the molten iron needs to be poured out. One end of the rotating rod 12 is fixedly installed with a round block 15, and a limiting rod 16 is arranged through the surface of the round block 15. The limiting rod 16 is slidably connected with the round block 15. One end of the limiting rod 16 is fixedly installed with a pulling block 17. A pulling spring 18 is sleeved on the surface of the limiting rod 16. One end of the pulling spring 18 is fixedly connected with the pulling block 17, and the other end of the pulling spring 18 is fixedly connected with the round block 15. A limiting hole 19 is opened on the surface of the vertical block 11. Pull the pulling block 17, and the pulling block 17 then drives the limiting rod 16 to leave the limiting hole 19. At this time, the diversion plate 14 is released from the limit. At this time, the diversion plate 14 can be rotated. After rotating the diversion plate 14 to the required angle, release the pulling block 17. Then, due to the pulling force of the pulling spring 18, the pulling spring 18 pulls the pulling block 17, and the pulling block 17 then drives the limiting rod 16 to move until the limiting rod 16 is inserted into the limiting hole 19. At this time, the diversion plate 14 can be limited. The limiting holes 19 are arranged in a circular shape on the surface of the vertical block 11.

[0034] Embodiment Three

[0035] Please refer to Figure 7 Figure 7 , a bottom plate 20 is fixedly installed on the bottom surface of the support plate 1. The material of the bottom plate 20 is austenitic stainless steel. A protection mechanism is provided on the top surface of the bottom plate 20. The protection mechanism includes a threaded rod 21, which is rotatably connected to the top surface of the bottom plate 20. A through groove 22 is opened on the side surface of the support plate 1. A moving plate 23 is slidably connected to the inner wall of the through groove 22. Threads are opened inside the moving plate 23, and the threads are engaged with the threaded rod 21. A clamping plate 24 is fixedly installed on the side surface of the moving plate 23. By providing the clamping plate 24, the melting furnace 3 can be protected, and the melting furnace 3 can be prevented from tipping over, further ensuring the stability of the melting furnace 3 and improving the safety. When it is necessary to tilt the melting furnace 3 for feeding, only need to rotate the threaded rod 21. The threaded rod 21 then drives the moving plate 23 to move. At this time, the moving plate 23 slides in the through groove 22. The moving plate 23 then drives the clamping plate 24 to move until the clamping plate 24 is far away from the melting furnace 3. At this time, the limit can be released.

[0036] Working principle: When the staff needs to pour out the molten iron, they only need to rotate the grip. The grip then drives the disc 5 to rotate, the disc 5 then drives the rotating shaft 2 to rotate, and the rotating shaft 2 can then drive the furnace 3 to rotate. After the furnace 3 is rotated to an inclined angle, the molten iron can flow out naturally. And the staff can also rotate the screw rod 7. At this time, since the inner wall of the cylinder 6 is provided with threads, the screw rod 7 moves in the cylinder 6 at this time, and the screw rod 7 then drives the grip to move. At this time, the grip can be pulled out, so that the distance of the grip can be pulled farther, enabling the staff to perform the rotation operation away from the furnace 3, reducing the probability of burns and improving work efficiency. And when the grip is not in use, the screw rod 7 can be retracted into the cylinder 6, which can reduce the occupied space of the grip and the screw rod 7. At the same time, after the screw rod 7 is retracted into the cylinder 6, the screw rod 7 can drive the insertion rod 8 to insert into the insertion hole 9, and at this time, it can play a limiting effect on the furnace 3. When the furnace 3 is rotated to an inclined angle and the molten iron flows out, the molten iron can fall on the guide plate 14 and finally flow out from the guide plate 14, which can avoid the residual molten iron on the top surface of the furnace 3. At the same time, the staff can also adjust the angle of the guide plate 14 according to the actual position where the molten iron needs to be poured out. During adjustment, only need to pull the pull block 17, and the pull block 17 then drives the limit rod 16 to leave the limit hole 19. At this time, the guide plate 14 is released from the limit, and then the guide plate 14 can be rotated. After rotating the guide plate 14 to the required angle, release the pull block 17. Subsequently, due to the pulling force of the tension spring 18, the tension spring 18 pulls the pull block 17, and the pull block 17 then drives the limit rod 16 to move until the limit rod 16 is inserted into the limit hole 19, and at this time, the guide plate 14 can be limited. The protection effect on the furnace 3 can be achieved through the provided clamping plate 24, which can prevent the furnace 3 from tipping over, further ensuring the stability of the furnace 3 and improving safety. And when it is necessary to tilt the furnace 3 for feeding, only need to rotate the threaded rod 21, and the threaded rod 21 then drives the moving plate 23 to move. The moving plate 23 slides in the through groove 22 at this time, and the moving plate 23 then drives the clamping plate 24 to move until the clamping plate 24 is far away from the furnace 3. At this time, the limit is released, and then the furnace 3 can be tilted normally for feeding.

[0037] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields.
