It is formed with the guide groove 38d of guiding guide part 31d.
Below in conjunction with a kind of installation process for handle box that Fig. 5-7 the present invention is described in detail provides.
Referring to Fig. 5, for handle box 1 of the present invention in disengaged orientation, the second elastic element 37 applies elastic force to engaging section
Part is at disengaged orientation.
Installation process is referring to Fig. 6, when the installation of handle box 1 of the present invention is into image forming apparatus, before machine driving head 100
End has arc surface 102 and plane 101, and arc surface 102 is contacted with the compression zone 31a of extensible member 31 first, with handle box
Further installation, machine driving head 100 apply extruding force F to extensible member 31, and extruding force F overcomes the reply of the first elastic element
Power F1, so that in axial direction X's extensible member 31 bounces back, deformation component 32 edge of the installation into extensible member 31 in retraction process
Axial direction X squeezes meshing part 34, and 34 stress of meshing part is rotated around mounting post card hole 38a, when putting down for machine driving head 100
When face 101 contacts extensible member 31, the engagement column 34a of meshing part 34 is fully rotating to the position of engagement, with machine driving head
Two projections mesh, so as to receive the driving force from machine driving head 100.
Disassembly process is referring to Fig. 7, when needing to take out handle box 1 of the present invention, along opposite with installation direction-direction disassembly
Box is managed, the plane 101 of machine driving head 100 is radially moved relative to extensible member 31, due to engaging column 34a at this time still
It is engaged with machine driving head, machine driving head 100 radially squeezes single engagement column 34a, extruded engagement column 34a rotation
Turn be squeezed and deformed component 32, due to deformation component 32 have deformable radial direction the deformations 32a, radial deformations 32a of stress by
Power radial deformation, so that single meshing part 34 has a small amount of radial displacement, the circular arc of subsequent machine driving head 100
Face 102 contacts compression zone 31a and makes extensible member 31 axially extending under the action of the restoring force F1 of the first elastic element 33,
As extensible member 31 is axially extended, extensible member 31 no longer squeezes meshing part 34, in 37 twisting force of the second elastic element
Under, it drives the rotation of meshing part 34 to disengaged orientation, can not be handled at this time with the taking-up that machine driving head 100 interferes
Box 1.
Since telescopic extensible member 31 is arranged on the driving assembly of handle box of the present invention and is driven by extensible member
The meshing part 34 engaged with machine driving head is rotated, meshing part 34 comes from the control of machine driving head 100 engaged to be stretched
Contracting component 31 stretches, and extruding of the extension and contraction control of extensible member 31 from machine driving head, such structure setting to drive
Dynamic head 100 can engage well transmitting power with meshing part, be not in the defect for falling off with not engaging.
Deformation component 32 has radial deformations 32a, is squeezed in disassembly and provides the position of radial direction for meshing part
It moves, handle box is efficiently removed.
Finally, it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
Present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: it still may be used
To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features；
And these are modified or replaceed, technical solution of various embodiments of the present invention that it does not separate the essence of the corresponding technical solution spirit and
Range.
