A pressing part 13 is arranged outside the shaft sleeve 11, and a wiring channel 111 is arranged between the pressing part 13 and the shaft sleeve 11. As shown in fig. 2, when the shaft sleeve 11 and the mounting tube 1211 are assembled in place, a portion of the sidewall of the adjusting box 12, which is provided with a first wire hole 1212, is located on a side of the pressing member 13 away from the wire channel 111, and the first wire hole 1212 is located between an inlet and an outlet of the wire channel 111.

The above solution provides a fan head assembly 10, wherein the first wire hole 1212 and the wire channel 111 are used for passing a power wire 20. The portion of the side wall of the adjusting box 12, which is provided with the first wire hole 1212, is located on a side of the pressing part 13, which is away from the wire channel 111, and the first wire hole 1212 is located between an inlet and an outlet of the wire channel 111. Further, the advancing direction of the power cord 20 from the first wire hole 1212 to the entrance of the wire routing channel 111 during the assembling process is different from the advancing direction of the entrance to the exit of the wire routing channel 111, so that as shown in fig. 2, one end of the power cord 20 on the pressing member 13 close to the entrance of the wire routing channel 111 is pressed and bent by the pressing member 13. Therefore, a large friction force exists between the power cord 20 and the pressing piece 13 as well as between the power cord and the side wall of the adjusting box 12, and the purpose of fixing the power cord 20 is achieved. The shaft sleeve 11 is assembled with the installation tube 1211 in place, and meanwhile, the fixing process of the power line 20 is achieved, and the overall assembly efficiency is improved.
