DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] As Figure 1-Figure 5As shown in the figure, a cutting machine includes a front end cover 1, an output end protective housing 2, a motor protective housing 3, a heat dissipation rear cover 4, a control motor 5, a transmission gear 6, and a cutting head 7. The control motor 5 is nested and installed inside the motor protective housing 3. A heat dissipation rear cover 4 is fixedly installed at the rear end of the motor protective housing 3. The motor protective housing 3 is fixedly connected to the output end protective housing 2. The front end cover 1 is fixedly connected to the output end protective housing 2. The power output end of the control motor 5 extends through the front end cover 1, and a cutting head 7 is installed at the end of the power output of the control motor 5. After disconnecting the connection between the output end protective housing 2 and the motor protective housing 3, the output end of the control motor 5 is exposed. A number of support seats are provided on the motor protective housing 3 and the output end protective housing 2.

[0026] Further, the front end cover 1 is fixedly connected to the output end protective housing 2 through a connecting member, the output end protective housing 2 is fixedly connected to the motor protective housing 3 through a connecting member, and the heat dissipation rear cover 4 is fixedly connected to the motor protective housing 3 through a connecting member.

[0027] Further, the front end cover 1 is fixedly connected to the output end protective housing 2 by screws, the output end protective housing 2 is fixedly connected to the motor protective housing 3 by screws, and the heat dissipation rear cover 4 is fixedly connected to the motor protective housing 3 by screws.

[0028] Further, a front support seat 21 is provided at the bottom end of the output end protective housing 2.

[0029] Further, a rear support seat 31 is provided at the bottom end of the motor protective housing 3.

[0030] Further, an auxiliary support seat 32 is also provided at the bottom end of the motor protective housing 3, and the auxiliary support seat 32 is located between the rear support seat 31 and the front support seat 21.

[0031] Further, the bottom surface of the front support seat 21 is larger than the bottom surface of the rear support seat 31.

[0032] Further, a number of strip-shaped heat dissipation grooves 41 are integrally provided on the heat dissipation rear cover 4, and the heat dissipation grooves 41 dissipate heat through side openings. That is, when looking at the heat dissipation rear cover 4 from the front, only the heat dissipation grooves 41 are presented on the heat dissipation rear cover 4, and no openings for heat dissipation are found. When looking from the side end, the openings for heat dissipation can be seen; to a certain extent, it can prevent external debris from entering the heat dissipation rear cover 4. Since a certain inclined surface can be set in the structure of the heat dissipation rear cover 4, it is beneficial to efficient lateral heat dissipation.

[0033] Further, an output gear 51 is nested on the output end of the control motor 5. A rotating shaft 53 is rotatably installed on the front end cover 1. A transfer gear 52 is provided at one end of the rotating shaft 53 close to the output gear 51, and the transfer gear 52 meshes with the output gear 51. That is, the transmission gear 6 includes the output gear 51 and the transfer gear 52.

[0034] Furthermore, the cutting head 7 is installed at one end of the rotating shaft 53 away from the output gear 51.

[0035] The control motor 5 specifically includes a stator and a rotor. A bearing is usually provided at the connection and cooperation between the rotor and the heat dissipation rear cover 4. The control motor 5 leads out a power plug for supplying energy to the motor. Taking the cutting machine including the structure of the intermediate gear 52 as an example for illustration, after the control motor 5 is started, the output gear 51 at the output end of the control motor 5 rotates, the output gear 51 meshes with the intermediate gear 52 to rotate, the rotating shaft 53 rotates stably on the front end cover 1, and the cutting head 7 on the rotating shaft 53 rotates for cutting.

[0036] The overall structure is compact. The cutting machine housing is composed of the front end cover 1, the output end protection shell 2, the motor protection shell 3, and the heat dissipation rear cover 4. If the heat dissipation effect of the cutting machine decreases, the heat dissipation rear cover 4 can be independently removed for maintenance; when cutting, if there is abnormal noise in the cutting machine, it can be considered whether the output gear 51 is abnormally worn. Separate the output end protection shell 2 from the motor protection shell 3 to expose the output end of the control motor 5 for maintenance. Since the rotating cutting part is at the front end of the cutting machine, the bottom surface of the front support seat 21 is set as a large-area bottom surface to improve the stability during support, which is beneficial to improving the cutting effect; the rear support seat 31 is provided to ensure the balance of front and rear support; the auxiliary support seat 32 is provided to improve the support effect of the cutting machine.
