[0026] A second cooling assembly 5 is provided on the outer wall of the outer casing 1;

[0027] A connection hole 101 is provided on one side of the outer casing 1.

[0028] The first cooling component 4 includes a ventilation slot 401, which is formed through one side of the inner wall of the housing 1.

[0029] The second cooling assembly 5 includes two heat sinks 501, both of which are disposed on one side of the outer wall of the housing 1, and both of the heat sinks 501 are provided with a silicone grease layer 502 on one side.

[0030] The operator inserts the motor output shaft through the shaft hole 3 and installs the motor inside the housing 1. The transition shaft is installed at the connection hole 101 of the housing 1. By setting the ventilation slot 401, outside air can enter the housing 1 through the ventilation slot 401, allowing the outside air to exchange with the internal hot airflow. At the same time, by setting the heat dissipation plate 501 with the base oil silicone grease layer 502, the heat accumulated inside the housing 1 is transferred to the heat dissipation plate 501 through the silicone grease layer 502, so that the heat dissipation plate 501 can dissipate this heat and prevent the motor from being damaged due to working in a high-temperature environment for a long time.

[0031] In another embodiment of this utility model, a number of heat dissipation fins 6 are fixedly installed on the side of the two heat dissipation plates 501 away from the silicone grease layer 502.

[0032] By setting the heat dissipation fins 6, the heat dissipation area of the heat dissipation plate 501 is increased, and the heat dissipation effect is enhanced.

[0033] In another embodiment of the present application, two heat dissipation plates 501 are provided with two mounting holes 7 on one side, and a connecting rod 8 is fixedly installed in each mounting hole 7.

[0034] A plurality of stepped holes 9 are formed through the inner wall of the shell 1 on one side surface, and each connecting rod 8 is inserted into the corresponding stepped hole 9.

[0035] Each stepped hole 9 is provided with a threaded hole 11, and each connecting rod 8 is provided with a threaded hole 11 at one end surface.
