[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3 This utility model provides an embodiment of a composite pressure transmitting block for synthesizing ultrafine diamond particles, comprising an outer cylinder 1, which provides a stable mounting base for the overall structure. A connecting component 2 is provided on the side wall of the outer cylinder 1, which stably connects the outer cylinder 1 to an inner cylinder 21, facilitating the replacement of the inner cylinder 21. A heating component 3 is provided below the connecting component 2, which ensures uniform heating of the inner cylinder 21. The connecting component 2 includes an inner cylinder 21 slidably connected inside the outer cylinder 1, which is used for composite pressure transmission of ultrafine diamond particles. A convex... Strip 22, the convex strip 22 and the outer cylinder 1 cooperate to facilitate the sealing of the connection between the outer cylinder 1 and the inner cylinder 21. The inner cylinder 21 has positioning grooves 23 on opposite side walls, which provide precise connection points for the inner cylinder 21. The top of the outer cylinder 1 has a groove 24, which provides a stable connection space for the convex strip 22. The opposite side walls of the outer cylinder 1 are fixedly connected to mounting boxes 25. The mounting boxes 25 are slidably connected to pull rods 26, which provide stable guidance and space for the pull rods 26. The surface of the pull rods 26 is fitted with springs 27, with the springs 27 near the outer cylinder 1. All are fixedly connected to a slide plate 28. A spring 27 provides stable elastic support for the slide plate 28, allowing the slide plate 28 to compress the spring 27 after movement. The spring 27 can drive the slide plate 28 to automatically return to its original position. A protrusion 22 is slidably connected inside a groove 24. A sealing ring is provided inside the groove 24. The protrusion 22 enters the groove 24 and, together with the sealing ring, seals the connection between the outer cylinder 1 and the inner cylinder 21, preventing heat loss during heating. A pull rod 26 is fixedly connected inside the slide plate 28, and the slide plate 28 is slidably connected inside the mounting box 25. The pull rod 26 can drive the slide plate 28. Synchronous movement is achieved, causing the pull rod 26 to slide the slide plate 28 inside the mounting box 25. The slide plate 28 ensures more stable movement of the pull rod 26. One end of the pull rod 26 near the slide plate 28 passes through the outer cylinder 1 and is slidably connected inside the outer cylinder 1. The other end of the pull rod 26 near the slide plate 28 is slidably connected inside the positioning groove 23. The pull rod 26 enters the positioning groove 23 through the outer cylinder 1 to fix the inner cylinder 21, so that the outer cylinder 1 and the inner cylinder 21 are stably connected. The slide plate 28 abuts against the side wall of the outer cylinder 1, and the outer cylinder 1 limits the slide plate 28, thereby limiting the pull rod 26.

[0032] Reference Figure 1 and Figure 4The heating assembly 3 includes a motor 31 fixedly connected to the side wall of the outer cylinder 1. A gear 32 is fixedly connected to the output end of the motor 31, and the motor 31 can provide stable rotational power to the gear 32. A gear ring 33 is rotatably connected inside the outer cylinder 1. A mixing rod 34 is fixedly connected to the inner wall of the gear ring 33. The gear ring 33 can drive the mixing rod 34 to rotate, disturbing the airflow. A heating plate 35 is fixedly connected to the inner wall of the bottom end of the outer cylinder 1, and the heating plate 35 can heat the inside of the outer cylinder 1. At least one connecting rod 36 is fixedly connected to the side wall of the outer cylinder 1. The connecting rod 36 reinforces the outer cylinder 1 and prevents the outer cylinder 1 from rotating with the gear ring 33. The gear 32 and the gear ring 33 mesh with each other. The rotation of the gear 32 can drive the gear ring 33 to rotate. The heating plate 35 abuts against the bottom end of the inner cylinder 21. The mixing rod 34 is located between the outer cylinder 1 and the inner cylinder 21. The mixing rod 34 disturbs the heating airflow of the heating plate 35, so that the hot airflow is evenly distributed between the outer cylinder 1 and the inner cylinder 21, maintaining the uniformity of heating.

[0033] Working principle: When the inner cylinder 21 needs to be replaced, pull the lever 26 outward. The lever 26 drives the sliding plate 28 to slide within the mounting box 25, compressing the spring 27. At this time, the lever 26 disengages from the positioning groove 23 on the side wall of the inner cylinder 21, releasing the restriction on the inner cylinder 21. Then, lift the inner cylinder 21 upward. The protrusion 22 on the side wall of the inner cylinder 21 slides along the groove 24, allowing the inner cylinder 21 to be removed from the outer cylinder 1, completing the disassembly. When installing a new inner cylinder 21, align the inner cylinder 21 with the outer cylinder 1, so that the protrusion 22... Strip 22 is embedded in groove 24, pushing inner cylinder 21 downward to a suitable position. Releasing pull rod 26 causes spring 27 to elastically return to its original position, pushing slide plate 28 and pull rod 26 to move. Pull rod 26 inserts into positioning groove 23, achieving a fixed connection between inner cylinder 21 and outer cylinder 1. When heating, motor 31 starts, transmission gear 32 rotates, and gear ring 33 rotates within outer cylinder 1 along with gear 32. Gear ring 33 drives mixing rod 34 to rotate synchronously, stirring the airflow between outer cylinder 1 and inner cylinder 21. Simultaneously, heating plate 35 at the bottom of outer cylinder 1 continuously heats up, transferring heat to the bottom of inner cylinder 21. The rotation of mixing rod 34 causes the medium to flow, allowing heat to be evenly distributed between outer cylinder 1 and inner cylinder 21, achieving uniform heating of inner cylinder 21 and its internal space.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
