Lock firm ironware 146 due to the press active force of the first elastic slice 145 slide to the right and with lock 149 lock fit of tooth, at this point, detent seat
118 are in the lock state, that is, convergence part 200 is in the lock state, and then, the first generator 136 of starting drives the first electricity-supplying piece
105 glide until bottom end is fully inserted into second into electric chamber 202, at this point, blower is powered, connection is finished.
When blower energization use, which finishes, to be needed to take out convergence part 200, the first generator of reverse starting 136 drives first
Sliding until returning to original state on electricity-supplying piece 105, then, the second generator of reverse starting 138 drives adjusting seat 135 to return to initially
State, at this point, electromagnet 144 be powered drive lock firm ironware 146 slide to the left and with the lock disengaging of tooth 149, then, reverse starting the
One generator 136 drive detent seat 118 be clockwise to original state, then, manually to the left pull convergence part 200 can gram
The elastic acting force for taking third elastic slice 115, which makes to slide pearl 116, to be skidded off card chamber 204 and pulls out convergence part 200.
The beneficial effects of the present invention are: due in the initial state, adjusting seat is in adjustment chamber left side wall, the 4th gear with
First gear engagement, the second electricity-supplying piece insertion first is intracavitary into electricity, at this point, electromagnet is in energized state and adsorbs the firm ironware of lock
It being detached from lock tooth, inserts chamber opening towards a left side, the first electricity-supplying piece is fully inserted into second sliding slot and on the upside of separation plate, at this point, every
It opens plate to completely enclose the first electricity-supplying piece since the pressure on top surface of the second elastic slice protrudes into second sliding slot, to increase the present apparatus not
Safety when use prevents accidental shock accident from occurring.
When needing that plate is aligned and is inserted into slotting chamber in use, picking up convergence part manually into electricity for blower, sliding pearl blocks
It is intracavitary to enter card, at this point, hand can be unclamped to convergence part, then, the first generator of starting drives detent seat to rotate counterclockwise, until
Convergence part is transferred to completely in intrusion slot and closing piece is transferred to completely and puts intracavitary, and then, the second generator of starting drives adjusting seat
Slide into adjustment chamber right side wall, at this point, the 4th gear is engaged with third gear, meanwhile, the second electricity-supplying piece disengaging first into electric chamber,
Electromagnet power-off, at this point, lock firm ironware due to the press active force of the first elastic slice slide to the right and with lock tooth lock fit, this
When, detent seat is in the lock state, that is, convergence part is in the lock state, and then, the first generator of starting drives the first electricity-supplying piece
Glide until bottom end be fully inserted into second into electricity it is intracavitary, at this point, blower be powered connection finish, be blower energization attended operation letter
Folk prescription just, increases safety in utilization, and when surprisingly touching convergence part, convergence part will not be undesirably fallen off, and increases stability in use,
Increase service life of fan.
When blower energization use, which finishes, to be needed to take out convergence part, the first generator of reverse starting drives the first electricity-supplying piece
Upper cunning is until return to original state, and then, the second generator of reverse starting drives adjusting seat to return to original state, at this point, electromagnetism
Tie Tong electricity drives the firm ironware of lock to slide and be detached to the left with lock tooth, and then, the first generator of reverse starting drives detent seat up time
Needle turns to original state, then, pulls convergence part that the elastic acting force of third elastic slice can be overcome to make to slide pearl to the left manually
