In this embodiment, the slider 521 is slidably connected inside the groove 520, and the slider 521 is connected to the limit plate 51 through a connecting member 522. By pulling the handle 54 upward, the handle 54 pulls the position-limiting plate 51 upward, and the position-limiting plate 51 drives the slider 521 via the link 522 to compress the spring 531 in the groove 520. The handle 54 drives the limiting plate 51 to move upwards, when the limiting plate 51 is far away from the magnetorheological damper body 2, the handle 54 is manually rotated, the handle 54 drives the limiting plate 51 to rotate, the limiting plate 51 drives the sliding piece 521 to rotate in the groove 520 through the connecting piece 522, and when the limiting plate 51 is separated from the side face of the magnetorheological damper body 2, the magnetorheological damper body 2 can be taken out, so that the magnetorheological damper body 2 can be conveniently replaced. The rotating member 52 can also be formed by a rotating disc and a connecting rod, the rotating disc is rotatably connected in the groove 520, so that the limiting plate 51 is conveniently driven to position the magnetorheological damper body 2, and the only limitation is not required here.

The working principle of the invention is as follows: when the magnetorheological damper body 2 operates, heat is generated, the motor 3121 is started, the output end of the motor 3121 drives the transmission shaft 3122 to rotate, the transmission shaft 3122 drives the fan blades 311 on the surface of the transmission shaft to rotate, the transmission shaft 3122 can drive the half gear 3221 on the surface of the transmission shaft to rotate while rotating, the half gear 3221 is connected with the rack 3223 on the inner side of the movable frame 3222 to drive the movable frame 3222 to move, and when the movable frame 3222 rotates, the guide groove 32242 can guide and limit the movable frame 3222 through the limit block 32241, so that the base 1 is cooled. When the heat in the base 1 is discharged, the motor 3121 is turned off, and the baffle 321 can be fixed in the limiting groove 325 under the action of the magnetic forces of the first magnetic block 3271 and the second magnetic block 3272, so that the ventilation opening 326 on the surface of the limiting groove 325 can be blocked, and further, external dust can be prevented from entering the base 1 through the ventilation opening 326. When the transmission shaft 3122 rotates, the transmission shaft 3122 can drive the incomplete gear 441 at the end portion thereof to rotate, when the incomplete gear 441 contacts the first gear 443, the incomplete gear 441 drives the rotation shaft 442 to rotate in the forward direction through the first gear 443, the rotation shaft 442 drives the two clamp plates 43 to slide in the sliding groove 42 to the left, so that the two clamp plates 43 drive the magnetorheological damper body 2 to slide in the left on the placement plate 41, when the incomplete gear 441 contacts the second gear 444, the incomplete gear 441 drives the rotation shaft 442 to rotate in the reverse direction through the second gear 444, the rotation shaft 442 drives the two clamp plates 43 to slide in the sliding groove 42 to the right, so that the two clamp plates 43 drive the magnetorheological damper body 2 to slide in the left and right on the placement plate 41, so that the magnetorheological damper body 2 reciprocates in the left and right on the placement plate 41, and the magnetorheological fluid inside the magnetorheological damper body 2 is driven to shake, the magnetorheological fluid which is precipitated can be uniformly dispersed, so that the damping effect of the magnetorheological damper body 2 is kept in a better state, and the condition that the damping effect of the magnetorheological damper body 2 is reduced due to the deposition of the magnetorheological fluid is avoided.
