The interference between the limiting part 33 and the second interference part 212 makes the resistance of the limiting part 33 larger in the process that the hook part 30 is separated from the accommodating space 20, indirectly causes the hook part 30 not to be easily separated from the accommodating space 20, and is beneficial to avoiding the unexpected separation of the hook part 30 from the accommodating space 20 when the hook 3 is not pulled. Further, when the hook 30 moves out of the accommodating space 20 from the accommodating position, the limiting portion 33 interferes with the second interference portion 212 as the limiting portion 33 slides over the second interference portion 212. The second interference portion 212 may be disposed at the first rib 221 and/or the second rib 231, and in this embodiment, one of the first rib 221 and one of the second rib 231 are respectively disposed with one second interference portion 212. During the process of pulling out the hook 3 to the pulled-out position, the limiting part 33 moves towards the yielding groove 24 along the interval 2510 between the at least one first rib position 221 and the at least one second rib position 231; the first rib 221 and the second rib 231 are parallel to the straight bar 31.

The support frame 2 is further provided with a first stop portion 280 and a second stop portion 281, the first stop portion 280 and the second stop portion 281 are adjacent to the yielding groove 24 respectively, the first stop portion 280 is spaced from the second stop portion 281, the first stop portion 280 and the second stop portion 281 are used for limiting the rotation angle range of the limiting portion 33, and in this embodiment, the rotation angle range of the hook 3 is about 180 degrees; when the hook 3 is in the pulled-out position, the stopper 33 can be rotated from a state of abutting against the first stopper 280 to a state of abutting against the second stopper 281. Further, the limiting portion 33 may rotate 180 degrees from a state of abutting against the first stopping portion 280 to a state of abutting against the second stopping portion 281. In this embodiment, the first stop portion 280 and the second stop portion 281 are respectively disposed on the second housing 23.

The support frame 2 is further provided with a third interference portion 282 adjacent to the yielding groove 24, and when the hook 3 moves to the pulled-out position, the limiting portion 33 rotates relative to the yielding groove 24, the limiting portion 33 interferes with the third interference portion 282 as the limiting portion 33 slides over the third interference portion 282. The limiting part 33 promotes the limiting part 33 to rotate through the third interference part 282, so that the hook 3 is not easy to rotate, and the position after rotation is promoted to be maintained. The third interference portion 282 is in the shape of a boss.

The support frame 2 is also provided with an opening 252, the opening 252 is positioned at the outer side of the outer section channel 250, the opening 252 is communicated with the outer section channel 250 and the outside, and the straight rod part 31 always penetrates through the opening 252 and the outer section channel 250 in the moving process of the hook 3 between the storage position and the pulling-out position; the relief groove 24 and the opening 252 are located on both the inner and outer sides of the outer channel 250. The design is favorable for the straight rod part 31 of the hook 3 to move stably along the opening 252 and the outer section channel 250.

When the hook 3 is at the pull-out position and rotates to any angle relative to the support frame 2 (any angle is within the range of the rotation angle of the hook 3 on the premise of not damaging the hook 3 and the support frame 2), the limiting part 33 can be hooked on the support frame 2 so that the hook 3 does not fall out of the support frame 2. In this embodiment, when the hook 3 is in the pulled-out position and rotates to an arbitrary angle with respect to the support frame 2, the limiting portion 33 selectively hooks on each of the gear plate 283 and the third interference portion 282 at the position of the yielding groove 24.

The limiting part 33 is formed by bending and extending from the straight rod part 31, and in this embodiment, the direction of the free end of the limiting part 33 is perpendicular to the straight rod part 31; the limiting part 33, the straight rod part 31 and the hook part 30 are positioned on the same plane, and the limiting part 33 and the hook part 30 are positioned at the opposite ends of the straight rod part 31 and at the same side of the straight rod part 31; the hook 3 is formed by bending a metal strip (such as a steel strip), and the limiting part 33 is integrally connected to one end of the straight rod part 31 away from the hook part 30 and is bent and extended from one end of the straight rod part 31 away from the hook part 30. So designed, the hook 3 is easier to bend and shape and has high strength and durability.

The upper end of the support frame 2 is rotatably connected to the machine head 10, the fan can be placed on the ground based on the support of the support frame 2, the bottom side of the support frame 2 is provided with a bottom wall 29 for being attached to the ground, the accommodating space 20 comprises an opening 200, the opening 200 is formed in the bottom wall 29 of the support frame 2, the opening 200 is directly communicated with the accommodating space 20 and the outside, the first interference part 210 is adjacent to the opening 200, and the hook part 30 enters and exits the accommodating space 20 through the opening 200. When the hook 3 is in the storage position, the first straight section 300 is located in the opening 200.
