The shaking head device 10 is generally provided with a power cord, and the traditional power cord is complex to assemble when being assembled, so that the assembly efficiency is influenced. In view of this, referring to fig. 2 and 3, in one embodiment, the adjusting member 100 is provided with an insertion hole 120 communicating with the first mounting cavity 110 and into which the lead wire 500 is inserted. In this embodiment, the conductive line 500 is a power line, and in other embodiments, the conductive line 500 may also be a line playing other roles, such as a data line. Referring to fig. 4, the mounting sleeve 200 is provided with a first mounting portion 212 for mounting the wire 500, and when assembling, the mounting sleeve 200 is inserted into the first mounting cavity 110, and at this time, the first mounting portion 212 and the side wall of the first mounting cavity 110 are spaced apart to form a fixing structure for fixing the wire 500. Specifically, the interval between the first mounting part 212 and the sidewall of the first mounting cavity 110 is set according to the size parameter of the wire 500, as long as the interval can fix the wire 500.
