After the air supply direction of the electric fan 11 is adjusted, the position of the rotating seat 17 is fixed by the positioning assembly, thereby achieving the adjustment of the air supply direction of the electric fan 11. When there is no other object for the clamping assembly to clamp, the clamping assembly clamps the fixing plate 27, and the clamping assembly is used to position the clamping assembly, so that the base 15 is used to support the electric fan 11, which is flexible to use.

[0040] like Figure 2As shown, as a preferred embodiment of the utility model, the clamping assembly includes:

[0041] An upper clamping plate 13, wherein the fixing seat 18 is fixedly disposed on the upper clamping plate 13;

[0042] The lower clamping plate 14 is rotatably connected to the upper clamping plate 13 via a connecting shaft;

[0043] The torsion spring 19 is sleeved on the connecting shaft of the upper clamping plate 13 and the lower clamping plate 14 , and the two ends of the torsion spring 19 are respectively against the upper clamping plate 13 and the lower clamping plate 14 .

[0044] In the embodiment of the utility model, the clamping assembly can be opened by pressing the upper clamping plate 13 and the lower clamping plate 14. After the clamping assembly is clamped on a designated object, the upper clamping plate 13 and the lower clamping plate 14 are released, and the torsion spring 19 is reset to complete the fixation.

[0045] like Figure 2 and Figure 3 As shown, as a preferred embodiment of the utility model, a fixing ring 25 is fixedly connected to the rotating seat 17, and the fixing ring 25 is slidably connected to the fixing seat 18. A positioning tooth 26 is fixedly connected to the bottom of the fixing ring 25, and an inclined wall is provided on the tooth groove of the positioning tooth 26.

[0046] In the embodiment of the utility model, a groove for the fixing ring 25 to rotate and a receiving groove 29 are formed in the fixing seat 18 , and the positioning tooth 26 is disposed in the receiving groove 29 .

[0047] like Figure 1-4 As shown, as a preferred embodiment of the utility model, the positioning component includes:

[0048] A positioning block 31, wherein the positioning block 31 is provided with an inclined wall, wherein the inclined wall of the positioning block 31 fits with the inclined wall on the tooth groove of the positioning tooth 26, and the positioning block 31 abuts against the tooth groove of the positioning tooth 26;

[0049] A positioning rod 32 is fixedly connected to the positioning block 31, and the positioning rod 32 is slidably connected to the fixing seat 18;

[0050] The limiting head 33 is fixedly arranged at the end of the positioning rod 32;

[0051] The spring 34 is sleeved on the outer ring of the positioning rod 32 , one end of the spring 34 is fixedly connected to the fixing seat 18 , and the other end of the spring 34 is fixedly connected to the limiting head 33 .

[0052] In the embodiment of the utility model, when the clamping assembly is clamped on a specified object and the air supply direction of the electric fan 11 needs to be adjusted, Figure 4Taking the direction as an example, the rotating seat 17 is rotated counterclockwise, and the rotating seat 17 drives the positioning tooth 26 to rotate counterclockwise through the fixing ring 25. At this time, the inclined wall on the tooth groove of the positioning tooth 26 squeezes the inclined wall of the positioning block 31, so that the positioning block 31 moves away from the positioning tooth 26. After the air supply direction of the electric fan 11 is adjusted to the specified air supply direction, the rotating seat 17 is stopped, and the spring 34 drives the positioning rod 32 to move in the opposite direction through the limit head 33, and the positioning block 31 is against the tooth groove of the positioning tooth 26, thereby completing the positioning.

[0053] like Figure 3 As shown, as a preferred embodiment of the utility model, the clamping assembly includes:

[0054] The screw rod 16 is threadedly connected to the base 15;

[0055] A pressing plate 28, the top of which is movably connected to the end of the screw rod 16;

[0056] The slide bar 21 is fixedly connected to the pressing plate 28 , and the slide bar 21 is slidably connected to the base 15 .

[0057] In the embodiment of the utility model, when there is no other object for the clamping assembly to clamp, the clamping assembly clamps the fixing plate 27 and screws in the screw 16, so that the clamping plate 28 moves toward the upper clamping plate 13, and the slide rod 21 guides until the clamping plate 28 presses the upper clamping plate 13 and stops screwing in the screw 16, thus completing the positioning of the clamping assembly and realizing the support of the base 15 for the electric fan 11.

The slide groove 22 is opened in the rotating seat 17, and an electric cylinder 24 is fixedly connected in the rotating seat 17. The output end of the electric cylinder 24 is fixedly connected to the bottom of the fixed rod 12.

[0059] In the embodiment of the utility model, when the height of the electric fan 11 needs to be adjusted, the electric cylinder 24 is started, the electric cylinder 24 drives the fixing rod 12 to move, and the slider 23 moves in the slide groove 22 to play a limiting role.

[0060] The working principle of the utility model is:

[0061] The new electric fan can be opened by pressing the upper clamping plate 13 and the lower clamping plate 14. After the clamping assembly is clamped on the specified object, the upper clamping plate 13 and the lower clamping plate 14 are released, and the torsion spring 19 is reset to complete the fixation. When the air supply direction of the electric fan 11 needs to be adjusted, the rotating seat 17 is rotated counterclockwise, and the rotating seat 17 drives the positioning tooth 26 to rotate counterclockwise through the fixing ring 25. At this time, the inclined wall on the tooth groove of the positioning tooth 26 squeezes the inclined wall of the positioning block 31, so that the positioning block 31 moves away from the positioning tooth 26. After the air supply direction of the electric fan 11 is adjusted to the specified air supply direction, the rotating seat 17 is stopped, and the spring 34 drives the positioning rod 32 to move in the opposite direction through the limit head 33, and the positioning block 31 is against the tooth groove of the positioning tooth 26, thereby completing the positioning. When there is no other object for the clamping assembly to clamp, the clamping assembly clamps the fixing plate 27 and screws in the screw 16, so that the clamping plate 28 moves toward the upper clamping plate 13, and the slide rod 21 guides until the clamping plate 28 presses the upper clamping plate 13 and stops screwing in the screw 16, thus completing the positioning of the clamping assembly and realizing the support of the base 15 for the electric fan 11.

[0062] The above are only preferred implementations of the utility model. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the utility model. These should also be regarded as the protection scope of the utility model. These will not affect the effect of the implementation of the utility model and the practicality of the patent.
