[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present invention sets a hinge assembly. After the pin is inserted into the third slide groove, the knob is turned.

[0017] 3. The present invention sets a limit assembly, and the connecting ring is detachably installed on one end of the heating ring body through the insertion groove. When the part needs to be heated, the staff inserts the part to be processed into the connecting ring, and the four telescopic rods clamp and limit the processed part through the limit roller under the action of the second spring. On the one hand, it can free the hands of the staff and eliminate the need for the staff to hold the parts for a long time, thereby reducing the workload of the staff. At the same time, the limit roller can ensure that the processed part is always in the center position of the heating ring, avoiding contact between the processed part and the inner wall of the heating ring, causing damage to the heating ring and the processed part.

[0029] The specific implementation method is as follows: by setting a cable duct seat 5, the cable duct seat 5 evenly arranges the heating coil 4 outside the heating ring body 1 to avoid the entanglement of the heating coil 4 and improve safety. By setting a connecting component 2, the clamping rod 207 slides into the groove 204 under the action of the elastic force of the first spring 205 and limits the clamping block 203. By controlling the clamping rod 207 to limit and separate the clamping block 203, the two heating ring bodies 1 can be quickly opened and closed.

[0031] The specific implementation method is as follows: by setting the ball 617, the ball 617 rotates on the top of the slide rod 603, which can reduce the friction between the slot 616. While ensuring the limiting effect of the pin 611, the rotation between the two heating ring bodies 1 can be smoother. Through the hinge assembly 6, through the convenient disassembly and assembly between the first connecting column 601 and the second connecting column 610, the disassembly and assembly process between the two heating bodies can be simplified, making the heating ring easy to disassemble and carry.

[0032] The limiting assembly 3 includes a connecting ring 301, a connecting groove 306 is provided at the bottom of the connecting ring 301, and the connecting ring 301 is inserted and connected to one end of the heating ring body 1 through the connecting groove 306. Telescopic rods 303 are fixedly connected to the inner wall of the connecting ring 301 all around, and one end of the telescopic rod 303 away from the inner wall of the connecting ring 301 is fixedly connected to a connecting seat 304, and one side of the connecting seat 304 is rotatably connected to a limiting roller 305 through a rotating shaft. A second spring 302 is sleeved on the outer surface of the telescopic rod 303, and both ends of the second spring 302 are respectively fixedly connected to one side of the inner wall of the connecting ring 301 and one side of the connecting seat 304.

[0033] The specific implementation method is as follows: by setting a limiting roller 305, the limiting roller 305 can rotate, thereby reducing the friction between the processing parts and the processing parts, making it easier to insert the processing parts into the connecting ring 301, and reducing the friction damage to the outer surface of the processing parts. By setting a limiting component 3, the four telescopic rods 303 clamp and limit the parts through the limiting roller 305 under the action of the second spring 302. On the one hand, it can free the hands of the staff and eliminate the need for the staff to hold the parts for a long time, thereby reducing the workload of the staff. At the same time, the limiting roller 305 can ensure that the processing parts are always in the center position of the heating ring, avoiding contact between the processing parts and the inner wall of the heating ring, causing damage to the heating ring and the processing parts.

[0034] Working principle: When in use, the staff assembles the two heating ring bodies 1, inserts the pin 611 into the third slide groove 613, and then turns the knob 609, which drives the movable lead screw 608 to rotate, and the movable lead screw 608 drives the lead screw seat 607 to move on the outer surface of the movable lead screw 608, and the movable lead screw 608 drives the internal second triangular plate 606 to move, and the second triangular plate 606 is attached to the first triangular plate 604 and exerts pressure on the first triangular plate 604, and the second triangular plate 606 drives the first triangular plate 604 to move downward, and the first triangular plate 604 is brought The movable slide rod 603 slides in the slide sleeve 615, and the slide rod 603 drives the ball 617 to embed into the slot 616 and fit with the inner wall of the slot 616. At this time, the hinge between the two heating ring bodies 1 is completed. When disassembly is required, the knob 609 is rotated in the opposite direction to separate the second triangular plate 606 from the first triangular plate 604. The slide rod 603 moves upward under the action of the third spring 614 and drives the ball 617 to separate from the slot 616, releasing the limit on the pin 611, so that the pin 611 can be separated from the third slide groove 613, thereby realizing the splitting between the first connecting column 601 and the second connecting column 610.

[0035] After the hinge between the two heating ring bodies 1 is completed, the assembly and closure between the two heating ring bodies 1 are realized through the connecting component 2. During this process, the staff brings the upper connecting block 201 and the lower connecting block 202 closer to each other, so that the block 203 at the bottom of the upper connecting block 201 is inserted into the groove 204. During this process, the block 203 slides down in the groove 204 and gradually fits with the clamping rod 207. The block 203 exerts pressure on the clamping rod 207 and drives the clamping rod 207 to move outward. At this time, the first spring 205 contracts. When the block 203 completely enters the groove 204, the clamping rod 207 slides into the groove 204 under the action of the elastic force of the first spring 205 and limits the block 203. When disassembly is required, the staff pulls the clamping rod 207 to both sides, and the clamping rod 207 releases the limit on the block 203. At this time, the staff moves the upper connecting block 201 upward, and the upper connecting block 201 is separated from the lower connecting block 202, realizing the disassembly between the two heating ring bodies 1.

[0036] After completing the assembly of the two heating ring bodies 1, the connecting ring 301 is detachably installed on one end of the heating ring body 1 through the insertion groove. When the parts need to be heated, the staff inserts the parts to be processed into the connecting ring 301, and the four telescopic rods 303 clamp and limit the parts under the action of the second spring 302.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
