213, two the 4th springs 237 are respectively sleeved on corresponding spring base 213, and its both ends contradicts in corresponding cunning respectively
In the side wall of block and the first cover plate.
When needing to be installed to impeller on motor shaft, motor shaft alignment axis hole is inserted into connection component, motor shaft contradicts
To the bottom surface of closing piece, closing piece is pushed up, second spring is squeezed compression, and closing piece is from the first sliding block and the second sliding block
Centre abjection, is cancelled to the spacing of the first sliding block and the second sliding block；The effect of first sliding block and the second sliding block in the 4th spring
Under inward against slip, the teeth groove on the first sliding block and the second sliding block is meshed with the latch of motor power output shaft, from
And locking motor power output shaft, motor install.
When needing to disassemble motor shaft from impeller, pushing hands is promoted, the 3rd spring is squeezed, and pushing block is pushed into
Into passage, inclined-plane extruding is domatic, the first sliding block and the second sliding block is extruded to the sidewall direction of the first cover plate, neck takes off
From latch, motor shaft departs from between two sliding blocks.
After motor shaft departs from, the active force revocation below closing piece, in the presence of second spring, closing piece moves down, and enters
To between the first sliding block and the second sliding block, stop to contradicting on two steps, two pieces of sliding blocks are spacing.
Revocation is applied to the active force in pushing hands, and pushing hands automatically resets in the presence of the 3rd spring, pushing block abjection passage.
Remaining content is same as Example 1.
