There is the screwed hole matched with pin, there is spring installation position between its other end and housing, spring is through the end of fixator
On, it is connected in spring installation position；With the housing of fixator screwed hole relative position on be provided with the loose slot of pin；Pin is worn
In loose slot on housing, it is fixed in fixator screwed hole；Described bridle is T-shaped, and T-shaped cross wall is fixed to stop
On ring, raised on perpendicular wall to have the projection matched with the Y-piece of the fixator of lock, the Y-piece of fixator is inserted in when in projection,
Locking is scheduled on bridle, prevents locating snap ring from rotating；When Y-piece departs from raised, lock is opened, and locating snap ring can rotate.The structure
Simply, use, locking reliability is high.
The spinner of spinner can be detachably fixed in its mounting disc using the present invention, carry out spiral
During oar flight-line service, as long as lock is opened, locating snap ring is rotated, locking pin is held displacement, removed from the smallest end of locking hole to big
Spinner, can carry out the flight-line service of propeller, after the completion of maintenance, then the locking pin on spinner is inserted in into mounting disc and stop
On ring, after moving locking to the smallest end of locking hole, then lock is fixed on bridle.Present invention dismounting is simple easily,
So that propeller flight-line service becomes simple and convenient, and parts are not damaged.

Specific embodiment
The present invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6 and Fig. 7, the present embodiment include locating snap ring 1, bridle 2, lock 3,
Multiple locking pins 6 and multiple screws 4.Bridle 2 is fixed on locating snap ring 1, and lock 3 is fixed in mounting disc 5, each locking pin
6 are fixed on spinner 7.The screw receiving hole of each screw 4, mounting disc are provided with the same circumference of the spinner 7 between locking pin 6
5 with spinner 7 on locking pin 6 and screw receiving hole correspondence position on be provided with screw fixed hole and locking pin fixing hole,
