[0027] Referring to Figure 1 as shown, the present utility model provides a technical solution: a desktop electric fan, including a base 1, a fan body 2 and an adjustment structure 4. The fan body 2 is installed on the base 1 by means of the adjustment structure 4. The surface of the fan body 2 is electrically connected to a power cord 3. An adjustment structure 4 is provided on one side of the base 1.

[0028] Specifically describe the specific settings and functions of its adjustment structure 4 below.

[0029] Refer to Figures 2 to 4As shown in the figure, in this embodiment: The adjustment structure 4 includes a fixed plate 401, the fixed plate 401 is fixedly connected to the base 1, an adjustment rod 402 is threadedly inserted on the surface of the fixed plate 401, the lower end of the adjustment rod 402 is rotatably connected to a clamping plate 403, and two round rods 404 are fixedly connected to the side of the clamping plate 403 close to the base 1. The arc surfaces of the two round rods 404 are slidably connected to the fixed plate 401. A support frame 406 is fixedly connected to the upper surface of the base 1. A connection block 407 is rotatably connected to the inner wall of the support frame 406. A limiting frame 408 is slidably connected to one side of the connection block 407. One end of the limiting frame 408 is fixedly connected to a spring 409. The end of the spring 409 away from the limiting frame 408 is fixedly connected to the connection block 407. A limiting rod 410 is fixedly connected to the end of the limiting frame 408 close to the support frame 406. A number of limiting holes 411 are opened on the side of the support frame 406 close to the limiting rod 410. The inner wall of one of the limiting holes 411 is slidably connected to the limiting rod 410. A support rod 413 is fixedly connected to the side of the connection block 407 away from the base 1. A moving frame 414 is slidably connected to the surface of the support rod 413. One side of the moving frame 414 is fixedly connected to the fan body 2. A positioning rod 415 is threadedly inserted on the side of the moving frame 414 away from the fan body 2. The clamping plate 403 and the base 1 can be used to fix the fan body 2 on the edge of a table or a workbench partition. By operating the connection block 407, the angle orientation of the fan body 2 can be adjusted. By means of the moving frame 414, the height of the fan body 2 can be adjusted. It has many applicable scenarios and can meet various usage requirements. Anti-slip pads 405 are fixedly connected to the sides of the base 1 and the clamping plate 403 close to each other. The anti-slip pads 405 are rubber pads. The friction of the clamping surface between the clamping plate 403 and the base 1 is increased through the anti-slip pads 405, so that the clamping effect of the clamping plate 403 and the base 1 is better. A pull ring 412 is rotatably connected to the surface of the limiting frame 408. By operating the pull ring 412 to drive the limiting frame 408 to move, it is convenient for the user to move the limiting frame 408. The end of the limiting rod 410 close to the limiting hole 411 is arc-shaped, and the insertion end of the limiting rod 410 is arc-shaped, which is convenient for the limiting rod 410 to slide into the limiting hole 411. Anti-slip grooves 416 are opened on the side of the support rod 413 close to the positioning rod 415. A number of anti-slip protrusions are fixedly connected to the inner wall of the anti-slip grooves 416. The friction between the positioning rod 415 and the support rod 413 is increased through the anti-slip grooves 416, so that the limiting effect of the positioning rod 415 is better. A number of pulleys 417 are rotatably connected to the inner wall of the moving frame 414. The arc surfaces of the pulleys 417 are slidably connected to the support rod 413. The friction between the inner wall of the moving frame 414 and the support rod 413 is reduced through the pulleys 417, so that the moving frame 414 moves more smoothly along the support rod 413. An auxiliary frame 418 is fixedly connected to the side of the moving frame 414 away from the positioning rod 415. The arc surface of the auxiliary frame 418 is slidably connected to the moving frame 414. The moving frame 414 is further limited through the auxiliary frame 418, so that the moving frame 414 moves more stably along the support rod 413.

[0030] Detailed usage method: By setting the adjustment structure 4, when it is necessary to fix the fan body 2 on the workstation partition, first rotate the adjusting rod 402. The adjusting rod 402 moves downward along the fixing plate 401 by means of the thread. The adjusting rod 402 drives the clamping plate 403 to move away from the base 1. During this process, the round rod 404 always slides along the fixing plate 401. After the clamping plate 403 moves away from the base 1 by a certain distance, move the base 1 and the clamping plate 403 closer to the partition so that the partition is located between the base 1 and the clamping plate 403. Then rotate the adjusting rod 402 in the reverse direction. The adjusting rod 402 moves along the fixing plate 401 by means of the thread. The adjusting rod 402 drives the clamping plate 403 closer to the base 1 until the clamping plate 403 cooperates with the base 1 to be clamped and fixed on the partition, thereby fixing the fan body 2 on the workstation partition. When it is necessary to adjust the tilting angle of the fan body 2, first slide the limit frame 408 away from the connecting block 407. During this process, the limit frame 408 drives the limit rod 410 to slide out of the limit hole 411, and the spring 409 is in a stretched state. Then rotate the connecting block 407 and the support rod 413 to make the fan body 2 face the appropriate angle. Then release the limit frame 408. The limit frame 408 slides into the connecting block 407 under the action of the elastic force of the spring 409. During this process, the limit frame 408 drives the limit rod 410 to move towards the support frame 406 until the limit rod 410 slides into the corresponding limit hole 411 to fix the angle of the connecting block 407 and the support rod 413. When it is necessary to adjust the height of the fan body 2, rotate the positioning rod 415. The positioning rod 415 moves along the moving frame 414 away from the support rod 413 by means of the thread to release the limit on the moving frame 414. At this time, the moving frame 414 can be lifted along the support rod 413 to an appropriate height. The moving frame 414 drives the fan body 2 to rise. Then rotate the positioning rod 415 in the reverse direction. The positioning rod 415 moves towards the support rod 413 by means of the thread until the positioning rod 415 tightly presses the support rod 413 to fix the position of the moving frame 414. Among them, the anti-slip pad 405 increases the friction between the clamping surface of the clamping plate 403 and the base 1, so that the clamping effect of the clamping plate 403 and the base 1 is better. By operating the pull ring 412 to drive the limit frame 408 to move, it is convenient for the user to move the limit frame 408. The insertion end of the limit rod 410 is arc-shaped, which is convenient for the limit rod 410 to slide into the limit hole 411. The anti-slip groove 416 increases the friction between the positioning rod 415 and the support rod 413, so that the limiting effect of the positioning rod 415 is better. The pulley 417 reduces the friction between the inner wall of the moving frame 414 and the support rod 413, so that the moving frame 414 moves more smoothly along the support rod 413. The auxiliary frame 418 further limits the moving frame 414, so that the moving frame 414 moves more stably along the support rod 413.
