It should be noted that the size of the first through hole 206b and the second through hole 206c is smaller than that of the cavity 206a, and the cavity 206a may be a cylindrical hole slot, wherein the second through hole 206c penetrates through the side plate 205, and it should be noted that the motor shaft 102 is disposed in the second through hole 206c, and the square column 103 is located in the fixing block 206.

A hexagonal groove 208a is arranged in the connecting shaft piece 208, and a first slot hole 208b and a second slot hole 208c which are communicated with the hexagonal groove 208a are respectively arranged at two ends of the connecting shaft piece 208; the first slot 208b interfaces with the first through-hole 206b, and the second slot 208c interfaces with the second through-hole 206 c.

The first slot 208b is provided with an auxiliary block 208d, and the auxiliary block 208d is provided with a first hexagonal slot 208 e.

The connecting piece 207 comprises a hexagonal block 207a and a third hexagonal column 207b, the hexagonal block 207a is arranged in the hexagonal groove 208a, and the hexagonal block 207a is connected with the side wall of the hexagonal groove 208a through a spring 207 c;

the third hexagonal column 207b is connected to the fan main body 202.

The hexagonal groove 208a and the hexagonal block 207a are configured to cooperate with each other, preferably, the cross section thereof is a regular hexagon, and it may also be a shape other than a circle, which makes the hexagonal block 207a only move along the length direction of the hexagonal groove 208a and not rotate relative to the hexagonal groove 208 a.

Furthermore, the side of the hexagonal block 207a facing the second slot 208c is provided with a square groove 207d, and the square groove 207d matches with the shape and size of the square column 103.

Preferably, the square groove 207d and the square column 103 are both square rectangles, and the central lines thereof correspond to each other.

Preferably, the spring 207c connects the hexagonal block 207a to the side of the hexagonal slot 208a where the first slot 208b is located, and the spring 207c tends to push the hexagonal block 207a toward the side of the hexagonal slot 208 c.

Specifically, when the motor main body 101 is fixed on the side plate 205, the motor shaft 102 is inserted into the second through hole 206c, and then the through holes on the connecting plate 104 are connected with the thread grooves on the side plate 205 in a one-to-one correspondence manner; during the process of inserting the motor shaft 102 into the second through hole 206c, the square column 103 has two situations, one is that the position of the square column 103 completely corresponds to the position of the square groove 207d on the hexagonal block 207a, the square column 103 is directly inserted into the square groove 207d, and the motor shaft 102 rotates to drive the hexagonal block 207a and the coupling member 208 to rotate together.

Secondly, if the position of the square column 103 does not completely correspond to the position of the square groove 207d of the hexagonal block 207a, the square column 103 pushes the hexagonal block 207a to move, compressing the spring 207 c.

The fan main body 202 comprises a middle column 202a and fan blades 202b, wherein the fan blades 202b are distributed on the side surface of the middle column 202 a; the middle post 202a is provided with a first hexagonal post 202c on one side, the first hexagonal post 202c being sized to mate with the first hexagonal slot 208 e.

The guard 203 includes an outer band 203a, a center plate 203b disposed at the center of the outer band 203a, and spokes 203c connecting the center plate 203b and the outer band 203 a.

A second hexagonal column 202d is arranged on the other side of the middle column 202a, and a fourth hexagonal groove 202e is arranged on the fan main body 202 in a penetrating manner; specifically, the fourth hexagonal groove 202e extends through the second hexagonal post 202d, the middle post 202a, and the first hexagonal post 202 c.

The second hexagonal post 202d is disposed at its end in the second hexagonal slot 203f, the third hexagonal post 207b passes through the fourth hexagonal slot 202e, and the third hexagonal post 207b is disposed at its end in the third hexagonal slot 203 g.

During the assembly of the fan main body 202, the fourth hexagonal groove 202e is sleeved on the third hexagonal column 207b from the end where the first hexagonal column 202c is located, and the fan main body 202 is close to the fixing block 206 until the first hexagonal column 202c is inserted into the first hexagonal groove 208 e; it should be noted that when the third hexagonal column 207b and the fourth hexagonal groove 202e are completely corresponding in position, the first hexagonal column 202c and the first hexagonal groove 208e are also completely corresponding simultaneously.

At this time, when the fan main body 202 is rotated, the first hexagonal pillar 202c drives the connecting shaft 208 to rotate, and the connecting shaft 208 drives the connecting member 207 to rotate, if the position of the square pillar 103 does not completely correspond to the position of the square groove 207d, in the process, when the position of the square pillar 103 rotates to completely correspond to the position of the square groove 207d, the hexagonal block 207a moves under the action of the spring 207c and is sleeved on the square pillar 103.

In this process, the third hexagonal pillar 207b provides a positioning shaft for the placement of the fan main body 202, so that the positioning shaft can be connected to the connecting member 207 and the connecting shaft 208, and on this basis, the rotation of the motor shaft 102 drives the connecting shaft 208 to rotate, and further drives the fan main body 202 to rotate under the cooperation of the first hexagonal pillar 202c and the first hexagonal groove 208e, and the third hexagonal pillar 207b and the fourth hexagonal groove 202 e.

The first hexagonal post 202c and the first hexagonal slot 208e are larger in size than the third hexagonal post 207b and the fourth hexagonal slot 202e, increasing torque and making the transmission more stable.

Finally, the shielding member 203 is fixed at the opening of the placing cavity 204, and the third hexagonal groove 203g is sleeved on the third hexagonal column 207b, and simultaneously, the second hexagonal groove is sleeved on the second hexagonal column 202d corresponding to the second hexagonal groove 203 f.

So far, when the motor shaft 102 rotates, the shaft connecting piece 208, the connecting piece 207 and the fan main body 202 are driven to rotate, and the whole of the shaft connecting piece 208, the connecting piece 207 and the fan main body 202 is connected with the fixed shell 201 through the first bearing 209 and the second bearing 203d, so that the rotating wear is small, and the efficiency is high.

It should be noted that, after the fan main body 202 is put in place, the third hexagonal column 207b protrudes from one end of the second hexagonal column 202 d.

It should be noted that the mating structures of the first hexagonal column 202c and the first hexagonal groove 208e, the second hexagonal column 202d and the second hexagonal groove 203f, and the third hexagonal column 207b and the third hexagonal groove 203g are all matched, and they cannot rotate relatively, but can move along a straight line.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; while the invention has been described in detail and with reference to the foregoing embodiments, it will be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; and the modifications or the substitutions do not make the essence of the corresponding technical solutions depart from the scope of the technical solutions of the embodiments of the present invention.
