Conflicting on the first cover plate 211 base and flange 247, flange 247 is separately positioned on the first wiper arm 242 and the second wiper arm 243
On sidewall.
First wiper arm 242 and the second wiper arm 243 head are provided with pushing block 248, and pushing block 248 has inclined-plane 249.
Accordingly, the first slide block 231 and the second slide block 232 are respectively equipped with the passage 234 that can house pushing block 248, passage
234 have domatic 236 corresponding with inclined-plane 249；By inclined-plane 249 with domatic 236 coordinate promote first and second sliding
Block slides in and out.
When wiper arm length is shorter, the first through hole passed through for lock dog 221 can be provided with in pushing hands 241
248’。
It is provided with two spring bases corresponding to the first slide block 231 and the second slide block 232 on the sidewall 214 of the first cover plate 211
213, two the 4th springs 237 are respectively sleeved on the spring base 213 of correspondence, conflict respectively at corresponding slide block and the in its two ends
On the sidewall of one cover plate.
When needing to be installed on motor shaft impeller, motor shaft being directed at axis hole and is inserted in connection assembly, motor shaft supports
Contacting the bottom surface of lock dog, by lock dog upwardly, the second spring is squeezed compression, and lock dog is from the first slide block and the second slide block
Between deviate from, that cancels the first slide block and the second slide block is spacing；First slide block and the second slide block under the effect of the 4th spring to
Interior slip relatively, makes the teeth groove on the first slide block and the second slide block be meshed with the latch of motor power output shaft, thus locks
Motor power output shaft, motor i.e. installs.
When motor shaft is disassembled from impeller by needs, promoting pushing hands, the 3rd spring is squeezed, and pushing block is pushed into
In passage, inclined-plane extruding is domatic, the first slide block and the second slide block is extruded to the sidewall direction of the first cover plate, and draw-in groove departs from card
Tooth, motor shaft departs between two slide blocks.
After motor shaft departs from, the active force below lock dog is cancelled, and under the effect of the second spring, lock dog moves down, and enters
To between the first slide block and the second slide block, stop, by spacing for two pieces of slide blocks on two steps to conflicting.
Cancelling the active force being applied in pushing hands, pushing hands automatically resets under the effect of the 3rd spring, pushing block abjection passage.
Remaining content is same as in Example 1.
