[0002] In operations such as cutting stone, walls, or grooving concrete, ring saws are a commonly used deep-cutting tool. They employ a ring-shaped saw blade, which is positioned and supported by a positioning device, and the saw blade is driven to rotate by a drive wheel to achieve cutting. However, most existing ring saws are driven by internal combustion engines such as gasoline engines. For example, a new type of ring saw with publication number CN223013568U uses an engine as a power source. However, compared with electric motors, this drive method has unstable output speed, resulting in difficulties in control and poor control precision.

[0003] Therefore, it is necessary to propose a dual-lithium battery type circumferential saw to solve the above-mentioned technical problems. Summary of the Invention

The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0023] like Figures 1-7 As shown, this utility model embodiment specifically provides a dual-lithium battery type circumferential saw, including: The drive motor 1 and the lithium battery pack 2 are respectively mounted on the frame 3, and the drive motor 1 is powered by the lithium battery pack 2. The belt drive mechanism 4 is installed on the cutter head holder 5. The power of the drive motor 1 is transmitted to the ring saw blade 6 through the belt drive mechanism 4 to drive the ring saw blade 6 to perform rotational cutting. The ring saw blade 6 is rotatably mounted on the cutter head holder 5 on the side away from the drive motor 1.

[0024] Lithium battery pack 2 consists of two 36V lithium battery packs connected in series. Power is supplied through lithium battery pack 2, eliminating the need for an external power source.

[0025] The belt drive mechanism 4 includes: a driving pulley 41, a driven pulley 42, a transmission belt 43, and a pinion 44. The driving pulley 41 and driven pulley 42 are rotatably mounted at both ends of the cutter head 5, respectively. The transmission belt 43 is wound between the driving pulley 41 and driven pulley 42. The pinion 44 is sleeved on the shaft end of the driven pulley 42, serving as the power output end of the belt drive mechanism 4. The driving pulley 41 is driven to rotate by the drive motor 1, and under the transmission action of the transmission belt 43 and driven pulley 42, the pinion 44 is synchronously driven to rotate.

[0027] It also includes an adjusting rod 77, an adjusting nut 78, and a limiting groove 79. The adjusting rod 77 is movably inserted into the cutter head holder 5. The limiting groove 79 is opened below the embedded groove 71, and the adjusting nut 78 is engaged in the limiting groove 79. The adjusting rod 77 is threaded into the adjusting nut 78. An adjusting block 72 is sleeved on the upper end of the adjusting rod 77, and a spring 75 is sleeved on the adjusting rod 77 between the adjusting block 72 and the moving block 74. When the above-mentioned tensioning mechanism 7 is in use, the tension force applied to the transmission belt 43 by the tensioning wheel 76 can be adaptively adjusted by the spring 75. Moreover, by rotating the adjusting rod 77, the adjusting rod 77 moves up and down under the action of the adjusting nut 78, thereby driving the adjusting block 72 on the adjusting rod 77 to move up and down.
