Connector 142 is crossed to be rotatably installed on propeller hub.The both ends of the connector 142 are arranged mounting groove, and connector 142 passes through the of blade
The second connecting portion of one interconnecting piece and propeller hub completes installation from both ends insertion mounting groove by fixing buckle 144.
The fastener 158 includes the interconnecting piece and buckling parts extended from propeller hub, and multiple fastener 158 is distributed in this
150 bottom of propeller hub.Multiple fastener 158 is angularly that 360/n ° (n is fastener number) is distributed in propeller hub bottom.
The articulated part 140 is metalwork, and is connected as one with blade injection molding, which further includes corresponding blade
The limiting groove 154 of setting, each limiting groove 154 are consistent with corresponding root of blade shape.
The articulated part 140 is in " I " fonts, which forms pivoted hole, the blade of each blade 100 and the pivot joint
140 integrated injection molding of part.The articulated part 140 and blade are integrated by mold injection molding, wherein the articulated part 140
Pivoted hole and propeller hub axial centerline parallel.The pivoted hole is set in 142 periphery of connector when installation, so that the blade can phase
Second connector 156,157 is rotated, which is metal copper sheathing or aluminium alloy workpiece.
In use, the fastener 158 of propeller is aligned with the biggish registration holes of the guide hole of installation part opening, so that spiral
Multiple fasteners 158 of paddle are also cross registration holes.Foldable propeller is pressed, so that spring-compressed, fastener enters installation
Part is rotated, directly when being depressed into elastic parts minimal compression amount according to the locking direction of rotation prompted on blade or spinner
The first retaining wall that installation part is touched to multiple fasteners 158 of propeller, slowly looses one's grip, this is more in the presence of elastic parts
A fastener 158 is engaged in the mounting groove of the installation part, that is, completes the installation of propeller.As shown in figure 12, when folding blade,
This is pushed both to complete to fold when turning to limiting groove 154 so that blade is rotated around articulated part 140 to blade.Wherein, paddle
Blade on hub can not be pushed towards the side of not limiting groove, and when reset, rotatable blade, which is unfolded, compresses root of blade
Propeller hub.
Similarly when dismantling propeller, user gently firmly pushes propeller.When being depressed into elastic parts minimal compression
When amount, counter-rotating is carried out according to the locking direction of rotation prompted on blade or spinner, when multiple fasteners 158 of propeller touch
When contacting the guide hole biggish contraposition wall surface of the hole of opening of installation part, propeller is lifted up, that is, completes the disassembly of propeller.
