Further, the blade positioning column does not connect one end with the paddle pressing plate or paddle fixed seat and is provided with threaded hole,
The position that the paddle pressing plate or paddle fixed seat correspond to the blade positioning column threaded hole is provided with connecting hole, tight by a paddle clamp lock
Screw links together the paddle pressing plate, blade positioning column and paddle fixed seat.
Further, the blade limited post is integrally formed with the paddle pressing plate.
Further, one group is symmetrically arranged in the middle part of the paddle pressing plate for paddle folder to be mounted on unmanned plane Power Component
Mounting hole, be provided in the middle part of the paddle fixed seat for mitigate overall weight and allow screw by engraved structure, pass through
Paddle mounting base lock-screw presss from both sides paddle in integral installation to unmanned plane.
The beneficial effects of the utility model are, increase the structure design of positioning column and limited post, limitation by being pressed from both sides to paddle
The fit clearance of blade and paddle folder increases the reliability of blade and paddle folder connection, improves what propeller was freely waved at work
The stability of reliability and working efficiency.

Specific implementation mode
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, is explained in further detail the utility model.It should be appreciated that specific embodiment described herein is only used for explaining this
Utility model is not used to limit the utility model, and forward and backward described in embodiment is subject to attached drawing, is only used for clear position
Relationship is set, is not used to limit.
On the contrary, the utility model cover it is any be defined by the claims do in the spirit and scope of the utility model
Replacement, modification, equivalent method and scheme.Further, right below in order to make the public have a better understanding the utility model
It is detailed to describe some specific detail sections in the datail description of the utility model.
As shown in Figs 1-4, it is the structural schematic diagram of the utility model one embodiment, which provides a kind of band positioning
The folding propeller paddle of column presss from both sides, including paddle pressing plate 1, paddle fixed seat 2, blade positioning column 3 and blade limited post 4, and the blade is fixed
Position column 3 and blade limited post 4 are arranged between the paddle pressing plate 1 and paddle fixed seat 2.
As shown in Figure 1,3, the setting of blade positioning column 3 at 1 both ends of paddle pressing plate or is arranged in the paddle fixed seat 2
Both ends, the blade positioning column 3 and the paddle pressing plate 1 or the paddle fixed seat 2 are integrally formed, the blade positioning column 3 not with
The paddle pressing plate 1 or paddle fixed seat 2 connect one end and are provided with threaded hole, and the paddle pressing plate 1 or paddle fixed seat 2 correspond to the blade
The position of 3 threaded hole of positioning column is provided with connecting hole, and lock-screw 5 is pressed from both sides by the paddle pressing plate 1, blade positioning column 3 by a paddle
It links together with paddle fixed seat 2.Blade positioning column 3 limits the installation adapted space of paddle folder and propeller, and paddle presss from both sides locking screw
Nail 5 can be locked arbitrarily, and the height of the blade positioning column 3, by machining accurate control, is adapted to corresponding model with diameter
Blade installs pore size with blade and height dimension is kept fixed gap and matches, and blade is waved not by lock-screw coupling mechanism force
Influence；Purpose is to ensure there is suitable gap between blade and paddle folder after blade is mounted on blade positioning column 3 so that
Blade is freely waved during the work time, is not influenced by installation error and uncertain factor.
As shown in Figs 1-4, the blade limited post 4 is symmetricly set on 1 bottom of paddle pressing plate, the blade limited post 4
It is arranged on 3 side of the blade positioning column and close to the position at 1 middle part of the paddle pressing plate, the blade limited post 4 and the paddle pressure
Plate 1 is integrally formed, and for the blade limited post 4 for propeller in folded state, limit sets the distance of two blades, avoids because of two
A blade is leaned on too close or is freely acted, and is destroyed under external force, plays the function of protection blade, while facilitating guarantor
Pipe preserves.
As shown in Figs 1-4,1 middle part of the paddle pressing plate, which is symmetrically arranged with one group, can allow paddle mounting base lock-screw 6 to pass through
Through-hole, 2 middle part of the paddle fixed seat are provided with the engraved structure for mitigating overall weight, and the engraved structure both sides correspond to logical
The position in hole is provided with mounting hole, is pressed from both sides paddle in integral installation to motor by paddle mounting base lock-screw 6.
When assembly, folding blade is first loaded onto paddle fixed seat 2 on paddle positioning column, paddle is locked with paddle folder lock-screw 5
Fixed seat 2, the fit clearance that blade is pressed from both sides with paddle is controlled by blade positioning column 3, highly consistent, is not pressed from both sides screw elasticity by paddle
Influence, ensure that blade freely wave at work with good dynamic balance performance, while ensure that the stabilization of working efficiency
Property.
The utility model structure avoids the defect for directly using screw lock blade, does not have loosened screw at work
Hidden danger；Avoid caused by loosened screw propeller gap increase caused by vibrations and blade work dynamic balancing difference lack
It falls into and the hidden danger such as working efficiency is unstable；It avoids during the work time, because screw generates tension when propeller rotates
And propeller and paddle is caused to press from both sides cooperation tension, cause blade that cannot freely wave, influences propeller whole dynamic balance poor performance
Hidden danger.
The beneficial effects of the utility model are, increase the structure design of positioning column and limited post, limitation by being pressed from both sides to paddle
The fit clearance of blade and paddle folder increases the reliability of blade and paddle folder connection, improves what propeller was freely waved at work
The stability of reliability and working efficiency.
