They are usually used in applications that require high flow but relatively low pressure, such as ventilation, air conditioning systems and air circulation.

[0003] A Chinese patent discloses an axial flow fan that is easy to adjust (publication number: CN218377004U). The device includes a base, a universal ball assembly and an axial flow fan body. One end of the universal ball assembly is mounted on the base, and the other end extends upward. The axial flow fan body is mounted on the end of the universal ball assembly away from the base. The universal ball assembly is used to adjust the direction and angle of the axial flow fan body. The axial flow fan body is mounted on the base through the universal ball assembly. The universal ball assembly is adjusted to adjust the height and direction of the axial flow fan body. However, the device still has the following defects:

[0030] The adjustment mechanism 2 also includes an outer frame 201. The main body of the outer frame 201 is hemispherical. An air inlet 202 is provided at one end of the outer wall of the outer frame 201. A bottom support 213 is fixedly connected to the bottom of the outer wall of the outer frame 201. Figure 1 As shown, bolts or screws can be inserted into the inner wall of the bottom support 213 to connect the lower support point;

[0031] The upper end of the inner wall of the outer frame 201 is rotatably connected to the upper clamping frame 203, and the lower end of the inner wall of the outer frame 201 is rotatably connected to the lower clamping frame 204.
