[0009] Preferably, a push shaft is provided inside the through hole, and the push shaft is located on the outer wall of the limiting hole and connected to a limiting block, the limiting block fits with the limiting hole, a buffer spring is connected to the outer wall of the limiting block, the other end of the buffer spring is connected to the inner wall of the limiting hole, and the buffer spring is sleeved on the outer wall of the push shaft.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] 1. By setting up the mounting frame and rubber pad, it is effectively prevented that children will bump into the electric fan and cause injuries. The base connected to the lower end of the mounting frame can effectively fix the electric fan on the desktop to avoid bumping or the desktop being tilted, so as to solve the existing safety hazards.

[0012] 2. By setting a protective pad, the base is placed on the desktop to prevent the base from moving, and the base is adsorbed on the desktop with a suction cup to facilitate the base to be adsorbed on the desktop to avoid bumps or the desktop being tilted and unable to be stably placed on the desktop;

[0013] 3. By pressing the push shaft into the through hole, the telescopic block is pushed so that the telescopic block extends into the step hole. When the telescopic block stops, the tension spring compressed by the fixed block rebounds, causing the suction cup to move and adsorb on the desktop, thereby increasing the adsorption force of the suction cup on the desktop and improving the stability between the base and the desktop.
