[0023] The above scheme is adopted: by starting the rotation of the rotating shaft 301 and energizing the control coil 204 at the same time, the magnetic powder clutch is operated to generate heat, and the internal heat is absorbed by the heat sink 302. The fan blades 304 are driven to rotate by natural wind, and the natural wind can be sucked into the shell to dissipate the heat of the heat sink 302. The effect of cooling the inside of the shell can be achieved without using electricity, thereby reducing the use cost, greatly extending the use time of the magnetic powder clutch, and improving the service life.

[0024] refer to Figure 1 and Figure 4 A fixing mechanism 4 is fixedly installed at the bottom of the support frame 1, and the fixing mechanism 4 includes a first support platform 401, a first fixed seat 402, a through groove 403, a second fixed seat 404, a return spring 405, a block 406 and a second support platform 407. The first support platform 401 is fixedly installed at the bottom of the support frame 1, the first fixed seat 402 is fixedly installed on the top of the first support platform 401, the through groove 403 is opened inside the first support platform 401 and the first fixed seat 402, the second fixed seat 404 is movably installed inside the through groove 403, one end of the return spring 405 is fixedly installed on the side of the second fixed seat 404, the block 406 is fixedly installed on the end of the return spring 405 away from the second fixed seat 404, and the second support platform 407 is fixedly installed at the bottom of the second fixed seat 404.

[0025] The above scheme is adopted: by bringing the second support platform 407 close to the lower mounting shell 201, the second fixing seat 404 enters the interior of the through groove 403, and the clamping block 406 can be squeezed through the inner wall of the through groove 403, and the clamping block 406 first enters the interior of the second fixing seat 404, and the reset spring 405 is tightened. When the second fixing seat 404 completely enters the interior of the through groove 403, the reset spring 405 resets and opens, and the clamping block 406 is moved out of the through groove 403, so that the first fixing seat 402 and the second support platform 407 can be fixed, and the clamping block 406 is sent into the interior of the second fixing seat 404 by pressing the clamping block 406, so that the first fixing seat 402 and the second fixing seat 404 are separated, so that the clutch body 2 is convenient to remove, and the fixing mechanism 4 ensures the stability of the magnetic powder clutch connection.

[0026] Working principle:

[0027] When in use, the second support platform 407 is brought close to the lower mounting shell 201, so that the second fixing seat 404 enters the interior of the through slot 403, and the block 406 is squeezed by the inner wall of the through slot 403 and first enters the interior of the second fixing seat 404, and the reset spring 405 is tightened. When the second fixing seat 404 completely enters the interior of the through slot 403, the reset spring 405 is reset and opened, and the block 406 is moved out of the through slot 403, and the first fixing seat 402 and the second support platform 407 are fixed. By pressing the block 406, the block 406 is sent into the interior of the second fixing seat 404, and the first fixing seat 402 and the second fixing seat 404 is separated, which makes it convenient to remove the clutch body 2. The fixing mechanism 4 ensures the stability of the magnetic powder clutch connection. Then, when the shaft 301 rotates, the control coil 204 is energized. After the magnetic powder clutch has worked for a period of time, heat is generated inside the shell, and the internal heat is absorbed by the heat sink 302. When the fan blades 304 encounter natural wind, they can rotate through the outer bearing 303 and suck the natural wind into the shell to dissipate the heat of the heat sink 302. The effect of cooling the inside of the shell can be achieved without using electricity, which reduces the cost of use, greatly extends the use time of the magnetic powder clutch, and improves its service life.

[0028] To sum up: this kind of magnetic powder clutch with good heat dissipation effect, through the setting of the heat dissipation mechanism 3, the fan blade 304 is installed on the outside of the outer bearing 303, the natural wind can drive the fan blade 304 to rotate, and the natural wind is sucked into the clutch for heat dissipation, and heat dissipation can be achieved without using electricity, which reduces the cost of use, and the clutch is installed with a heat sink 302, which has the function of absorbing heat. After the clutch is used for a long time, the heat generated is absorbed by the heat sink 302, and then the heat is dissipated by the natural wind sucked by the fan blade 304, which greatly improves the service life of the magnetic powder clutch, through the setting of the fixing mechanism 4, the clutch body 2 is close to the second support platform 407, and the clutch body 2 and the second support platform 407 can be quickly fixed and disassembled by extrusion, which not only ensures the stability of the connection of the magnetic powder clutch, but also facilitates its inspection and maintenance. At the same time, the magnetic powder clutch can be assembled quickly and conveniently, extending the service life of the clutch.
