In order to prevent the adjusted fan from changing position again, the operator can additionally set limiting mechanism, in the embodiment, bottom plate 308 below main plate 301 can provide horizontal locking effect, when operating, the operator rotates bidirectional screw rod 305, at this time, second nut 306 at both ends moves towards each other, and drives bottom plate 308 to move outward under the drive of connecting rod until the friction block 309 at the edge of bottom plate 308 contacts with the inner wall of slide groove, generates friction and realizes fixation.

[0033] The positioning mechanism 5 comprises a guide pipe 501, a third nut 502 and the like, the guide pipe 501 is fixedly installed in the inner support 4, the third nut 502 is rotatably installed at the end of the guide pipe 501, the inner side of the third nut 502 is provided with a second screw rod 503, and the end of the second screw rod 503 is provided with a supporting plate 504; in order to guarantee the stability of the fan during use, the positioning mechanism 5 is further added in the design to provide additional fixing effect for the fan body. When positioning the fan in the inner support 4 after moving, the operator needs to rotate the third nut 502 on the side of the second screw rod 503 under the condition that the second screw rod 503 does not self-rotate, and then locks after the supporting plate 504 at the end thereof contacts the outer frame of the inner support 4.

[0034] In the embodiment, the end of the first screw rod 303, the bidirectional threaded screw rod 305 and the second screw rod 503 is detachably installed with a locking nut 6. By arranging the locking nut 6, the components can be effectively locked, the loosening of the threads is prevented, the stability and reliability of the structure are further enhanced, the fastening state of the components can be maintained during long-time use, and the loosening phenomenon caused by vibration or other external forces is avoided.

[0038] When the support for the fan of the embodiment is used, first, the whole outer support 2 is fixed at the predetermined installation position through the suspender 1. The inner support 4 is firmly combined with the fan through the plurality of fixing rods, so as to ensure the stability of the fan. In the initial state, the bottom plate 308 does not contact the inner side wall of the sliding groove of the outer support 2, and the moving mechanism 3 can move horizontally in the sliding groove. The operator can push the moving mechanism 3, so as to adjust the position of the fan in the horizontal direction, and ensure that the fan is in the best position.

[0039] When the height of the fan needs to be adjusted, the operator holds the fan to prevent it from self-rotating, then rotates the first nut 302, thereby driving the fan to move up and down along the vertical direction, and finally locks through the locking nut 6 after the height is determined, so as to complete the adjustment of the height of the fan.

[0040] After the fan position adjustment is completed, in order to prevent the fan from shifting during operation, the operator can rotate the bidirectional threaded screw 305 to drive the second nuts 306 at both ends to move towards each other. At this time, the second nuts 306 promote the bottom plate 308 to slide outward through the connecting rod until the rubber friction blocks 309 at the edge of the bottom plate 308 contact the inner wall of the sliding groove of the outer support 2 to provide friction, thereby locking the moving mechanism 3 and realizing the fixation of the fan in the transverse direction.

[0041] In addition, the positioning mechanism 5 further stabilizes the fan through the guide pipe 501, the second screw 503 and the support plate 504 at the end of the second screw 503. When positioning the fan, the operator can rotate the third nut 502 to push the second screw 503 and the support plate 504 to contact the outer frame of the inner support 4 to provide additional fixed support.
