Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The utility model discloses the motor model who mentions in does: 39BYG201-B-50 may be available in a market place or a private subscription.

Referring to fig. 1-4, an electric fan for offices comprises a box body 1, a grid 2 is arranged at one end of the box body 1, a connecting frame 3 is arranged at the bottom end of the box body 1, a motor 13 is connected to the inner wall of the box body 1, a rotating shaft 12 is arranged at the output end of the motor 13, a connecting disc 7 is arranged at one end of the rotating shaft 12, fan blades 6 are arranged on the outer side of the connecting disc 7, a connecting column 11 is arranged at the bottom of the motor 13, a baffle 8 is arranged on the outer surface of the connecting column 11, an adjusting screw 4 is arranged on the penetrating property of the connecting column 11, a base 5 is arranged on the penetrating property of the connecting frame 3.

Please refer to fig. 1, the width of the connecting frame 3 is equal to that of the box 1, so as to increase the contact area between the connecting frame 3 and the box 1, thereby facilitating the better support of the connecting frame 3 on the box 1.

Please refer to fig. 2, two bases 5 are provided, one of the bases 5 and the limiting plate 10 is connected to the surface of the limiting plate 10 through the internal thread of the rotating screw 9, and the two bases 5 are combined with each other by rotating and pressing the rotating screw 9.
