They are indispensable new functional materials in information technology, energy technology, modern ultra-precision processing technology, aerospace technology, military technology and other fields. Currently, the synthesis of gem-grade synthetic large-grain diamonds has become a trend in the development of the industry.

[0003] After searching, a Chinese patent with a patent announcement number of CN206127482U discloses a composite insulation device for gem-grade large single crystal synthesis, including a double-layer composite structure arranged outside a graphite column, the double-layer composite structure includes an insulation layer 1 and an insulation layer 2 arranged in sequence, the insulation layer 1 is arranged in contact with an external heating element, and the insulation layer 2 is arranged in contact with the graphite column. The utility model has a simple structure, a novel and reasonable design, and a double-layer composite insulation structure is arranged on the periphery of the graphite column, which can effectively prevent the diamond from absorbing impurities during synthesis, while ensuring the stability of the insulation performance of the large single crystal for a long time synthesis, and improving the quality of gem-grade diamond products.

[0004] However, the above design still has some shortcomings. In the above design, double-layer composite insulation is used to cover the gem-grade large single crystal, thereby achieving the insulation effect of the gem-grade large single crystal. However, since the double-layer composite insulation is not effectively fixed, the double-layer composite insulation is likely to shift in position during operation, which is not conducive to the synthesis of gem-grade large single crystals.

Both sides of the rotating rod 902 are fixedly connected with screw rods 904, and the outer wall of the screw rods 904 is threadedly connected with a moving block 909. Positioning holes 907 are provided on the sides of the two moving blocks 909 that are away from each other. Positioning rods 908 are movably provided inside the positioning holes 907, and the positioning rods 908 are fixedly connected with the moving blocks 909. Slide grooves 905 are provided on the top and bottom of the moving blocks 909. The inner wall of the slide groove 905 is slidably connected with a slider 906, and the slider 906 is fixedly connected with the moving blocks 909;

[0027] Specifically, Figure 1 , Figure 2 and Figure 4As shown, when it is needed to cover the gem-grade large single crystal with the double-layer insulating body 1, the gem-grade large single crystal is first placed on the placement plate 2, and then the double-layer insulating body 1 is placed just above the placement plate 2, and the mounting block 5 is aligned with the mounting groove 6, and then the double-layer insulating body 1 is moved downward until the mounting block 5 is inserted into the mounting groove 6, and then the hexagonal screw head 8 is rotated by a tool, and the rotation of the hexagonal screw head 8 drives the worm 903 to rotate, and the rotation of the worm 903 drives the rotating rod 902 to rotate through the worm gear 901, and the rotation of the rotating rod 902 drives the two screws 904 to rotate, and the rotation of the two screws 904 drives the two moving blocks 909 to move in a direction away from each other, and the movement of the two moving blocks 909 drives the two positioning rods 908 to approach the positioning hole 90 7, until the positioning rod 908 is inserted into the positioning hole 907, thereby completing the fixation of the mounting block 5, and then completing the fixation of the double-layer insulating body 1. Similarly, the hexagonal screw head 8 is rotated in the opposite direction by the tool, and finally the positioning rod 908 is driven to disengage from the positioning hole 907, and then the double-layer insulating body 1 is moved upward until the mounting block 5 is disengaged from the mounting groove 6, thereby completing the separation of the double-layer insulating body 1 and the placement plate 2. The operation is simple and practical, and the problem of covering the gem-grade large single crystal with the double-layer composite insulation is solved, thereby achieving the insulation effect of the gem-grade large single crystal. However, since the double-layer composite insulation is not effectively fixed, the double-layer composite insulation is likely to be displaced during operation, which is not conducive to the synthesis of gem-grade large single crystals.

[0028] A double-layer insulating body 1 is fixedly connected to the top of the mounting block 5, and the double-layer insulating body 1 includes a first insulating layer 101, and a second insulating layer 102 is fixedly arranged on the inner side of the first insulating layer 101.

[0029] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, when in use, after the double-layer insulating body 1 is fixed, the threaded cover 4 is then screwed into the protective tube 3. During this process, the abutment block 7 will move toward the direction close to the hexagonal screw head 8 until it contacts the hexagonal screw head 8 and exerts a certain extrusion pressure on it, thereby effectively preventing the hexagonal screw head 8 from rotating, thereby improving the stability of the double-layer insulating body 1 after being fixed.

[0030] Working principle: In the present application, when it is necessary to cover a gem-grade large single crystal with a double-layer insulating body 1, the gem-grade large single crystal is first placed on the placement plate 2, and then the double-layer insulating body 1 is placed directly above the placement plate 2, and the mounting block 5 is aligned with the mounting slot 6, and then the double-layer insulating body 1 is moved downward until the mounting block 5 is inserted into the mounting slot 6, and then the hexagonal screw head 8 is rotated by a tool, and the rotation of the hexagonal screw head 8 drives the worm 903 to rotate, and the rotation of the worm 903 drives the rotating rod 902 to rotate through the worm gear 901, and the rotation of the rotating rod 902 drives the two screws 904 to rotate, and the rotation of the two screws 904 drives the two moving blocks 909 to move in a direction away from each other, and the movement of the two moving blocks 909 drives the two positioning rods 908 to a direction close to the positioning hole 907 Move until the positioning rod 908 is inserted into the positioning hole 907, thereby completing the fixation of the mounting block 5, and then completing the fixation of the double-layer insulating body 1. Similarly, the hexagonal screw head 8 is rotated in the opposite direction by a tool, and finally the positioning rod 908 is driven to disengage from the positioning hole 907, and then the double-layer insulating body 1 is moved upward until the mounting block 5 is disengaged from the mounting groove 6, thereby completing the separation of the double-layer insulating body 1 and the placement plate 2. Secondly, when the double-layer insulating body 1 is fixed, the threaded cover 4 is then screwed into the protective tube 3. During this process, the abutment block 7 will move toward the direction close to the hexagonal screw head 8 until it contacts the hexagonal screw head 8 and exerts a certain extrusion pressure on it, thereby effectively preventing the hexagonal screw head 8 from rotating, thereby improving the stability of the double-layer insulating body 1 after fixation.
