As shown in figure 4, the driving head 50 in image forming apparatus is provided with front end cylinder 50b, in front end, cylinder 50b's is upper
Side is provided with recess 50a, and along the circumferentially equidistant from arrangement of driving head 50, recess 50a prolongs recess 50a along the axis of driving head 50
It stretches and is closed in the upper end of front end cylinder 50b.When handle box is installed in image forming apparatus, before driving head 50
The press-side 13a of newel post body 50b pressing coupling pawls 13 may be such that coupling pawl 13 is rotated and engaged with driving head, this will below
Detailed description.
In the following, elaborating handle box with reference to Fig. 4 and Fig. 5 is installing into detailed forming apparatus is schemed drive component 10 with driving
Drive component 10 and driving head 50 is disengaged from when first 50 engagement process and handle box are dismantled from image forming apparatus
Process.As shown in figure 4, handle box is installed along X-direction substantially parallel with the axis of driving head 50 in image forming apparatus,
Before coupling pawl 13 is contacted with driving head 50, coupling pawl 13 is opened by the biasing force bias of elastic component 15 in rotating outward
The position opened, for the convenience of description, the position for hereinafter rotating coupling pawl 13 outward and opening is known as coupling beating for pawl 13
Open position.When coupling pawl 13 is in an open position, the front end cylinder 50b of driving head 50 will extend over the power reception end of coupling pawl
13c, and abuts to apply pressure with coupling the press-side 13b of pawl 13, press-side 13b are after the pressing force of reception driving head 50 gram
The elastic force for taking elastic component 15 rotates inwardly, and after handle box is installed to final position, power reception end 13c is caught in driving
It completes in first 50 recess 50a to engage with driving head 50, it, will coupling pawl 13 in the present embodiment in order to obtain smaller torque
Rotational trajectory described in be arranged in plane it is parallel with the axis direction of flange components 11.For the convenience of description, hereinafter by coupling
Pawl 13 is closed to rotate inwardly and eventually stop at the closed position of position referred to as coupling pawl 13 engaged with recess 50a.Driving head
50 transmit rotary driving force by recess 50a with engaging to drive component 10 for power reception end 13c, and drive component 10 again will
Rotary driving force passes to each stressed member in handle box.Power reception end 13c has inside guide part 13c2.When needing to dismantle
During handle box, inside guide part 13c2 is abutted with recess 50a by the closed end of front end cylinder 50b sides can force coupling pawl 13
Open position is moved to from closed position and is finally disengaged from driving head 50.In order to enable the installation process of handle box is more
Stablize, position opposite with inside guide part 13c2 on the power reception end 13c of coupling pawl 13 is provided with outer in the present embodiment
Side guide part 13c1, even if the setting of outside guide part 13c1 when coupling the position deficiency that pawl 13 rotates outward so that still may be used
It couples pawl 13 with the cooperation by outside guide part 13c1 and front end cylinder 50b and rotates further out, front end cylinder
50b is able to smooth cross power reception end 13c.
In the present embodiment, since the driving head 50 in image forming apparatus has certain elastic expansion range in itself.
Therefore, in the installation process of handle box, though occur coupling pawl 13 power reception end 13c in a rotational direction with recess 50a
The state not being aligned, after image forming apparatus starts, with the rotation of driving head 50, when the recess 50a of driving head 50 revolves
Can also be coupled when going to coupling position that pawl 13 is aligned by the press section 13b to pressing coupling pawl 13 pawl 13 rotate to
Closed position completes engagement action with driving head 50.
In the present embodiment, have been shown in particular and realize coupling pawl 13 and driving head 50 using the rotary motion for coupling pawl 13
The structure for engaging and being disengaged from.It will be appreciated by those skilled in the art that the motion mode of coupling pawl 13 not only may be used
Moving in rotation can also be realized by the way of translation, for example, will the press-side of pawl and the split of power reception end can be coupled
Setting when press-side is pressed, realizes the translation at power reception end so that power using the translation of press-side
The recess engagement of receiving terminal also driving head, can equally reach the technique effect of the utility model.
Drive component and handle box provided by the utility model, the structure for coupling pawl is simple, and flexibility ratio is high, and will not go out to deposit
In the situation of the thin material in part, mechanical performance is strong, and connection may be damaged when transferring a driving force to wheel hub by solving coupling part
Portion and the problem of lead to that driving force cannot be transmitted.
Above example is only to illustrate the technical solution of the utility model, rather than its limitations；Although with reference to aforementioned reality
Example is applied the utility model is described in detail, it will be understood by those of ordinary skill in the art that：It still can be to preceding
The technical solution recorded in each embodiment is stated to modify or carry out equivalent replacement to which part technical characteristic；And these
Modification is replaced, the spirit and model of various embodiments of the utility model technical solution that it does not separate the essence of the corresponding technical solution
It encloses.
