First fool proof portion 25a and the second fool proof portion 25b can be mutually butted, so as to increase the propeller 20a and the interlocking
Mounting distance between portion 14a, so that both can not connect.
During assembling, first the drive shaft 15 is assembled in the connecting hole 2311a by way of interference fit, it is first fixed
Concentricity and perpendicularity between the propeller 20a and driving means 10a, the blend stop 232a of the blade seat 21a leads to
The clamping part 140a for crossing the lock-joining part 14a is stretched in described group of entrance 26a, subsequently, pushes the oar of the propeller 20a
Trichidium 21a, the resilient member 13 is entered direction and is rotated the propeller 20a by compressive strain under the connecting hole 2311a to group
The blend stop 232a groups are made to enter under the ladder block 146 of the lock-joining part 14a.And release when pushing the propeller 20a, due to
The resilient member 13 is flexibly supported on the blade seat 21a, the effect of the elastic force of the resilient member 13, each blend stop
232a correspondences are fastened on the ladder block 146, and the propeller 20a is in the lock state.
When needing to pull down the propeller 20a from driving means 10a, the blade seat 21a is pushed, it is described
Resilient member 13 pushes contraction by the blade seat 21a, makes the blend stop 232a leave the ladder block 146, then to group
Enter direction in opposite direction and rotate the propeller 20a, now, the propeller 20a is in released state, the blend stop 232a
Depart from from the side of the ladder block 146, the blend stop 232a is retracted into described group of entrance 26a, so as to realize the propeller 20a with
The separation of driving means 10a.
Those skilled in the art are it should be appreciated that the embodiment of the above is intended merely to illustrate that this practicality is new
Type, and be not used as be to restriction of the present utility model, if within spirit of the present utility model, it is real to more than
Apply appropriate change that example made and change all falls within the scope of this utility model is claimed.
