[0024] like Figures 1-6 As shown, a fabric cutting machine includes a drive motor 1, a fabric cutting roller 2, a housing 3, and an assembled mobile battery 4. The drive motor 1 is locked inside the front end of the housing 3, and the output end of the drive motor 1 is connected to the fabric cutting roller 2. A control circuit board is installed inside the rear end of the housing 3, and a control switch 5 is soldered on the control circuit. The trigger end of the control switch 5 is located on the surface of the housing 3. The assembled mobile battery 4 is assembled and installed at the rear end of the housing 3. A conductive sheet is soldered to one end of the control circuit board near the assembled mobile battery 4. The assembled mobile battery 4 is locked to the housing 3 by a locking fastener 7 and is connected to the conductive sheet for power supply. A matching frame 8 for stabilizing the rotation of the fabric cutting roller 2 is locked and installed at the front end of the housing 3. A hollow structure 81 for heat dissipation is formed between the matching frame 8 and the housing 3.

[0025] Furthermore, a heat sink 9 is coaxially mounted on the output end of the drive motor 1.

[0026] Furthermore, the inner surface of the housing 3 is provided with several guide grooves 10.

[0027] Furthermore, the housing 3 has a bent structure with a bending angle of 120°-150°, preferably 130°.

[0028] Furthermore, a heat dissipation plate 31 is nested in the housing 3 on the side of the control circuit board.

[0029] Furthermore, the heat dissipation plate 31 is symmetrically mounted on the casing 3.

[0030] Furthermore, the radius of the bend in the housing 3 is smaller than the radius of the housing 3 at both ends.
