When being transported to the fan class product such as stand fan, slide fan, wherein the fan blade and guard component of composition fan
Generally be packaged with, and fan blade be fixed in guard component, wherein, guard component generally fastened by two parts guard and
Into, fan blade is fixed therein on a guard, be typically fixed to positioned at rear portion guard (be after herein with respect to user and
Speech, in fan blow-through user, before the side close to user is, the side away from user is rear) on, to prevent fan blade from transporting
During collided with guard component.In order to more easily fix fan blade and guard, this application provides one kind to be used for
The fixture of fixed fan blade and guard.The structure of guard and fan blade is as shown in figure 1, existing guard 4 is typically provided with middle part
Centre bore 41, the wheel hub 21 of fan blade 2 including middle part and the blade 22 being arranged on wheel hub 21, drive shaft is provided with wheel hub 21
Hole 23, drive shaft hole 23 are non-circular hole, such as D-shaped hole, the circular hole with keyway, square opening etc., so as in fan in use,
The drive shaft of the drive device of fan can drive fan blade 2 to rotate.Usually, as shown in figure 5, being provided with the middle part of wheel hub 21 logical
Hole, mounting sleeve 24 in through hole, axle sleeve 24 is interior to form drive shaft hole 23.As shown in Figures 2 and 3, fixture 1 includes stopper section
11 and the elastic clamping hook 12 that is arranged on stopper section 11, elastic clamping hook 12 include elastic arm 122 and be arranged on elastic arm 122
On hook part 121, in this way, elastic clamping hook 12 through guard 4 centre bore 41 and fan blade 2 drive shaft hole 23, hook part 121 is worn
Go out, in this way, fan blade 2 and guard 4 are positioned between stopper section 11 and hook part 121.It is understood that elastic clamping hook 12 herein
