The material of the easy consumption used in equipment is generally called printing consumables.In general, carbon dust consumed by developing generally is mentioned by handle box
For, after the carbon dust in handle box is finished, then the handle box more renewed.
Existing handle box, generally include powder cabin, be arranged in powder cabin with developing cell cooperation driving part, development
Conductive contact in roller, powder outlet cutter, transmission gear and conducting end and conducting end on handle box end cap, and comprising useless
The developing device of powder cabin and photosensitive drums.Handle box is placed in imaging device, the driving part of handle box with setting by existing
Rotating driving element coupling in imaging device, driving part rotate to realize in handle box with imaging device actuated element
Developing cell rotates in a circumferential direction movement.The conductive contact of handle box conducting end is contacted with conductive site on imaging device, makes handle box
Internal development component is according to the carbon dust inside the positively charged pressure of design feature or negative voltage powder cabin in developer roll and other components electricity
To photosensitive drums powder supply under field force effect, to develop to photosensitive drums, then carbon dust is transferred on paper by transferring.Work as processing
When carbon dust in box exhausts, handle box need to be unloaded from imaging device.
A kind of driving part of existing handle box is the drive connection structure using sphere type universal joint, in the process of transport
In, driving assembly is easily separated from, and is caused photosensitive drums or developer roll that can not receive driving force, is caused handle box can not normal use.
In addition there are also a kind of handle box, the driving body of rod in driving assembly passes through the gear positioning component of Locating driver,
And it can be slided relative to gear axial reciprocating, during mounting and dismounting handle box, driving assembly is easy and imaging
The driving head of device is stuck, and driving assembly is caused to damage, and can not work normally handle box.
Summary of the invention
In order to realize that the main object of the present invention, the present invention provide a kind of handle box, it is intended to improve handle box in the machine that falls and

Referring to Fig. 6 and Fig. 7, the driving head 8 of printer can be along its axial stretching, when handle box 1 needs to place to printer
When internal, the handle portion 21 that user holds handle box 1 places handle box 1 to printer.During user holds, draw
The forced section 51 of bar 5 receives with the holding active force movement of accommodating chamber side wall 211 towards handle portion 21, is driven by interconnecting piece 52
Pushing part 53 is moved along the axis direction perpendicular to bar portion 311, i.e., the lug boss 532 of pushing part 53 is mobile towards lead ring 33, from
And the axis direction that lug boss 532 forces lead ring 33 to receive head 31 along driving force is moved close to the end 312 that driving force receives head 31
It is dynamic, while driving spacer pin 32 that mandril 35 is driven to move along the outside of the axis direction nose portion 312 of driving force reception head 31,
The first return springs 6 and the second return springs 7 are in confined state at this time.It places in handle box 1 to printer
During portion, the top of 35 nose portion 312 of mandril acts on the driving head 8 of printer, forces 8 edge of driving head of printer
It is axially retracted, so that the driving head 8 of printer and two dogs 313 of end 312 be avoided to interfere, and handle box 1 is made to exist
It falls during machine the obstruction that not will receive certain components and interference and generates stuck phenomenon.
After handle box 1 is placed to printer completely, user's release treatment box 1, in the first return springs 6 and the
Under the rebound effect of two return springs 7, the forced section 51 of pull rod 5 is mobile far from the accommodating chamber side wall 211 of handle portion 21, leads to
Crossing interconnecting piece 52 drives pushing part 53 to move along the axis direction perpendicular to bar portion 311, i.e. the lug boss 532 of pushing part 53 is separate
Lead ring 33 is mobile, and the driving head 8 of printer forces mandril 35 along the axis of driving force reception head 31 axially extendedly along its at this time
Retraction end 312 is mobile in direction, while the axis direction for driving spacer pin 32 that lead ring 33 is driven to receive head 31 along driving force is remote
It is mobile from end 312, so that two dogs 313 of end 312 be made steadily to be engaged with the driving head of printer 8, at this moment dog
313 may be implemented steadily to be rotatably assorted with the driving head 8 of printer.
After the carbon dust in handle box 1 has printed, need to take out handle box 1 from printer, user holds handle box 1
Handle portion 21 pull handle box 1 outward.During user holds, the forced section 51 of pull rod 5 is received with holding active force
Accommodating chamber side wall 211 towards handle portion 21 is mobile, drives pushing part 53 along the axis perpendicular to bar portion 311 by interconnecting piece 52
Direction is mobile, i.e., the lug boss 532 of pushing part 53 is mobile towards lead ring 33, so that lug boss 532 forces lead ring 33 along driving force
The axis direction for receiving head 31 is mobile close to the end 312 that driving force receives head 31, while spacer pin 32 being driven to drive mandril 35
It is moved along the outside that driving force receives the axis direction nose portion 312 of head 31, the first return springs 6 and second reset at this time
Elastic component 7 is in confined state.During handle box 1 is removed out of printer, the top of 35 nose portion 312 of mandril
End acts on the driving head 8 of printer, and the driving head 8 of printer is forced to axially retract along it, realizes two dogs of end 312
313 disengage with the driving head 8 of printer, can swimmingly take out handle box 1.
It controls lead ring 33 using pull rod 5 to move back and forth along the axis direction that driving force receives head 31, to pass through lead ring 33
It moves or interior retraction the outside for the axis direction nose portion 312 for driving mandril 35 to receive head 31 along driving force with spacer pin 32
End 312 is mobile, to make handle box 1 that can swimmingly fall machine and remove from host.Also, it is more stable that handle box 1 falls machine, beats
Print more stable, the driving head 5 of printer receives head 31 with the driving force of handle box 1 and can correctly and fully be engaged, and improves place
The compatibility of box 1 is managed, cost performance is higher.
