Referring to Fig. 9 and Figure 10, laser printer host driven axis 4 can be along its axial stretching, when handle box 1 is placed to printing
Before machine inside, the other end of connector 31 is socketed on the free end on the head 331 that driving force receives head 33, i.e. connector 31
Internal gear 312 engaged with the external gear 334 on head 331.Then, handle box 1 is placed to printer, while pressing pushes away
The forced section 61 of compression bar 6 makes lug boss 62 receive 332 ground of bar portion of head 33 along the axis perpendicular to bar portion 332 towards driving force
Direction is mobile, so that lug boss 62 forces bar portion 332 that head 331 and connector 31 is driven to move together towards driving 34 direction of gear
It is dynamic, until the boss 333 of bar portion 332 is resisted against on the outer end face of axial limiting part 32, thus laser printer host driven axis 4
Driving head 41 can swimmingly into connector 31 inclusion cavity 311 in, reset spring 36 and return springs 7 are at this time
Confined state.
After placement to the printer completely of handle box 1, cancel the pressing active force of forced section 61, in reset spring 36
Under the rebound effect of return springs 7, bar portion 332 drives head 331 and connector 31 together far from driving 34 side of gear
To movement, until spacer pin 35 is resisted against on the inner face of axial limiting part 32, return springs 7 force lug boss 62 remote at this time
From bar portion 332, so that inclusion cavity 311 fully accommodates the driving head 41 of laser printer host driven axis 4, thus laser printing
Machine host drive shaft 4 is stably driven with the rotation of connector 31, and connector 31 drives head 331 and the rotation of bar portion 332 until limit
The both ends of pin 35 respectively with 322 abutting contact of the first position limit arm 321 and the second position limit arm, so that gear 34 be driven steadily to revolve
Turn.During the placement of handle box 1 to printer, even if the biography of connector 31 and laser printer host driven axis 4
Dynamic head 41 has the contact of part, and connector 31 can also force the driving head 41 of laser printer host driven axis 4 along its axial direction
Inside contract, make handle box 1 not will receive during falling machine certain components obstruction and interference and generate stuck phenomenon.
After the carbon dust in handle box 1 has printed, need to take out handle box 1, the processing of pulling outward from printer
The forced section 61 that push strut 6 is pressed while box 1 makes lug boss 62 towards 332 ground of bar portion along the axis side perpendicular to bar portion 332
To movement, so that lug boss 62 forces bar portion 332 that head 331 and connector 31 is driven to move together towards driving 34 direction of gear
It is dynamic, until the boss 333 of bar portion 332 is resisted against on the outer end face of axial limiting part 32, thus laser printer host driven axis 4
Driving head 41 can swimmingly be disconnected the inclusion cavity 311 of part 31, can swimmingly take out handle box 1.
Driving head 331 and connector 31 together by bar portion 332 can move along the axial reciprocating of driving gear 34, and
Cooperated using the inclusion cavity 311 of connector 31 and the driving head 41 of laser printer host driven axis 4, while connector 31 is removable
It is connect with head 331 with unloading, to make handle box 1 that can swimmingly fall machine and remove from host.Also, the containing of connector 31
Chamber 311 can fully contain the driving head 41 of laser printer host driven axis 4, and it is more stable that handle box 1 falls machine, print more steady
It is fixed, the compatibility of handle box 1 is improved, cost performance is higher.
Handle box second embodiment:
As the explanation to handle box second embodiment of the present invention, below only to the difference with handle box first embodiment into
Row explanation.
Referring to Figure 11 to Figure 13, one end of the cylindrical setting of the present embodiment connector 8, connector 8 has removably
The inclusion cavity 81 of the driving head 41 of laser printer host driven axis 4 is accommodated, offers Y type groove on the other end of connector 8
82, driving force receive head 37 head 371 free end face on be provided with Y type dog 374, Y type dog with axially protruding
In 374 pluggable Y type grooves 82.
Laser printer host driven axis 4 can be along its axial stretching, when handle box (not indicating) places to printer
Before, one end of connector 8 is socketed on the driving head 41 of laser printer host driven axis 4, i.e. the inclusion cavity 81 of connector 8
Fully contain the driving head 41 of laser printer host driven axis 4.Then, handle box is placed to printer, simultaneously
The forced section 61 for pressing push strut 6 moves lug boss 62 along the axis direction perpendicular to bar portion 372 towards 372 ground of bar portion, from
And lug boss 62 forces bar portion 372 to drive head 371 mobile towards driving 34 direction of gear together, until the boss of bar portion 372
373 are resisted against on the outer end face of axial limiting part 32, so that the Y type dog 374 on head 371 can swimmingly can be inserted into connector 8
Y type groove 82 in, reset spring 36 and return springs 7 are in confined state at this time.
After handle box is placed completely to printer, cancel the pressing active force of forced section 61, in reset spring 36
Under the rebound effect of return springs 7, bar portion 372 drives head 371 mobile far from driving 34 direction of gear together, until
Spacer pin 35 is resisted against on the inner face of axial limiting part 32, and return springs 7 force lug boss 62 far from bar portion 342 at this time,
To head 371 Y type dog 374 axially be completely inserted into connector 8 Y type groove 82 in, thus laser printing machine host
Drive shaft 4 is stably driven with connector 8 and head 371 is driven to rotate, while driving the rotation of bar portion 372 up to the both ends of spacer pin 35
Respectively with 322 abutting contact of the first position limit arm 321 and the second position limit arm, so that gear 34 be driven to be stably rotated.In handle box
During placing to printer, even if having the contact of part between the Y type dog 374 and connector 8 on head 371,
The Y type dog 374 on head 371 can also force connector 8 to drive the driving head 41 of laser printer host driven axis 4 along its axial direction
Inside contract, make handle box not will receive during falling machine certain components obstruction and interference and generate stuck phenomenon.
After the carbon dust in handle box has printed, needs to take out handle box from printer, pull handle box outward
While press push strut 6 forced section 61, make lug boss 62 towards 372 ground of bar portion along perpendicular to bar portion 372 axis direction
It is mobile, so that lug boss 62 forces bar portion 372 to drive head 371 mobile towards driving 34 direction of gear together, until bar portion 372
Boss 373 be resisted against on the outer end face of axial limiting part 32, so that the Y type dog 374 on head 371 can be swimmingly disconnected
The Y type groove 82 of part 8, can swimmingly take out handle box.
Connector 8 is removably mounted on the driving head 41 of laser printer host driven axis 4 as individual part,
Driving head 371 together by bar portion 372 can move along the axial reciprocating of driving gear 34, to make handle box that can swimmingly fall
It machine and is removed from host.Also, the Y type dog 374 on head 371 can be fully inserted into the Y type groove 82 of connector 8, processing
It is more stable that box falls machine, prints more stable, improves the compatibility of handle box, cost performance is higher.
