Upper shaft sleeve is mounted in the middle part of the lower end of pedestal, is fixed with stepper motor in the pedestal, is pacified on the output shaft of the stepper motor
Equipped with gear, the gear is engaged with fluted disc, and the upper end of the pedestal is symmetrically arranged with support frame, after being equipped on the inside of support frame
Shell, the sidewall symmetry of the rear shell are embedded with steel ball sleeve, on support frame as described above and fixed equipped with angle with steel ball sleeve intersection
Bit slice, the angle positioning sheet are set as the sheet metal being made of annular circular hole, and rear shell is bolted in support frame as described above.
Preferably, the side wall of support frame as described above and be located at bolt on the outside of be connected with trim.
Preferably, the bottom on the chassis is equipped with Slippery proof foot pad.
The technical effect and advantage of the utility model:The fan, structurally reasonable, practical, steel ball sleeve and angle are fixed
The setting of bit slice can position the pitch angle of rear shell, keep angular adjustment more convenient, and stepper motor passes through gear and fluted disc, band
Dynamic base rotation keeps stepper motor rotating load more uniform to make fan head swinging, improves motor service life, Er Qiexiang
Existing head shaking structure for fan is more simplified.
