As shown in fig. 9 a and fig. 9b, power reception part 21 is located at first position relative to power output member 30, at this point, power
Receiving element 21 is not combined with power output member 30, and the rotation axis L2 and L3 of the two are parallel to each other, along direction of rotation r, rotary shaft
Line L2 is located at the upstream of rotation axis L3.
Power transmission 20 is rotated with Delevoping cartridge shell 10 along direction shown in r, and power transmission 20 moves closer to
Power output member 30, as shown in figs. 10 a and 10b, power reception part 21 are gradually combined with power output member 30, in the knot of the two
It is possible that two kinds of situations during conjunction:
The first situation, the camber line where the r of direction of rotation pass through space S, then power reception part 21 can be with power output
Part 30 smoothly combines；
Second situation, the camber line where the r of direction of rotation are not passed through space S, then power reception pawl 212 can be to power reception
The combination of part 21 and power output member 30 forms interference.
When there is above-mentioned second situation, power reception part 21 will receive the active force from power output member 30, with
Further rotating for Delevoping cartridge D, the active force force power reception part 21 to move to close to the direction of Delevoping cartridge shell 10, together
When, power reception part 21 drives engaging member 22 to be directed to the guiding of part 126, and engaging member 22 starts the first end from guide member 126
126a is moved to second end 126b, and since guide member 126 is distorted shape, the motion profile of engaging member 22 is also twisting curve,
In turn, engaging member 22 forces power reception part 21 to do curvilinear motion while close to Delevoping cartridge shell 10 again.
With the rotation of Delevoping cartridge D, when power reception pawl 212, which is no longer formed power output member 30, interferes, power is connect
Addressee 21 is combined with the completion of power output member 30, as shown in Figure 10 B, the rotation axis L21 and power output of power reception part 21
The rotation axis L3 of part 30 is conllinear, and power reception part 21 is located at the second position relative to power output member 30；Thus, power reception
For part 21 during moving to the second position from first position, power reception part 21 does song under the action of the first control mechanism
Line movement, and power reception part 21 do curvilinear motion direction it is opposite with the direction of rotation of Delevoping cartridge D.
As described above, sliding part 23 is configured to cross-shaped chute coupling, the power reception part 21 combined with sliding part 23 can
In the planar movement vertical with rotation axis L2, therefore, no matter which kind of curvilinear motion power reception part 21 does, in sliding part 23
Under effect, the movement of power reception part 21 can be realized.In above-mentioned second situation, power reception part 21 is carried out ultromotivity
After the active force of output 30, under the guide function of guide member 126, on the r of direction of rotation, power reception part 21 is moved closer to
Outlet 124, meanwhile, power reception part 21 will force compressed spring 24 to be compressed close to the movement of Delevoping cartridge shell 10.
As seen in figs. 11a and 11b, power reception part 21 is in the third place relative to power output member 30, at this point, dynamic
Power receiving element 21 is combined with the disengaging of power output member 30.The mistake of combination is progressively disengaged in power reception part 21 and power output member 30
Cheng Zhong, power reception part 21 are gradually no longer influenced by the active force from power output member 30, in the elastic reset of compressed spring 24
Under power effect, power reception part 21 drives engaging member 22 gradually to reset under the guide function of guide member 126, thus, power connects
During moving to the third place from the second position, power reception part 21 is done addressee 21 under the action of the first control mechanism
Curvilinear motion, and power reception part 21 do curvilinear motion direction it is identical as the direction of rotation of Delevoping cartridge D；When power reception part 21
When completely disengaging combination with power output member 30, as shown in Figure 11 B, power output member 30 moves to outlet 124, along rotation axis
R, rotation axis L21 are located at the downstream of rotation axis L3.
As the transformation of the embodiment of the present invention, the guide member (guide projections) 126 can also exchange with guide channel 223,
I.e. guide channel 223 is arranged on fixed part 128, and guide member 126 is arranged on engaging member 22.
[shape of power reception pawl]
Figure 12 A is that the position in power reception part of the present invention on the inside of power reception pawl between power output member is closed
System's figure；Figure 12 B is the positional relationship in power reception part of the present invention between power reception pawl top and power output member
Figure；Figure 12 C is the location diagram in power reception part of the present invention on the outside of power reception pawl between power output member.
As described above, power reception pawl 212 has opposite inner surface 212a and outer surface 212b, it is as shown in Figure 4 A, interior
Surface 212a and outer surface 212b is curved surface, and being respectively provided with inner vertex P1 and outer dead centre P2, the inner vertex P1 is interior table
Near the point of rotation axis L21 on the 212a of face, outer dead centre P2 is the point on the 212b of outer surface farthest away from rotation axis L21, because
And inner vertex P1 relative to outer dead centre P2 closer to rotation axis L21, in the embodiment of the present invention, along rotation axis L21, interior top
Point P1 and outer dead centre P2 is different with a distance from rhabodoid 211, as shown, inner vertex P1 is than outer dead centre P2 further from rhabodoid
211, in other words, inner vertex P1 is than outer dead centre P2 closer to power reception pawl top surface 214.
As illustrated in fig. 12, rotary shaft 31 includes integrally formed first part 31a and second part 31b, first part
The diameter of 31a is greater than the diameter of second part 31b, has on the intersection of first part 31a and second part 31b from rotary shaft
Line L3 farthest outermost point P3.When power reception part 21 is combined with power output member 31, along rotation axis L3, outermost point P3 ratio
Inner vertex P1 is further from rhabodoid 211, as shown in Figure 12 B, when being observed along the direction perpendicular to rotation axis L21, power reception
Pawl top surface 214 is no more than power output rod 32, it is preferred that power reception pawl top surface 214 is flushed with power output rod 32.
When power reception part 21 needs to be combined with the disengaging of power output member 30, power output member 30 is easier to connect to power
Addressee 21, which applies, forces power reception part 21 to the active force far from power output member 30, i.e., power reception part 21 is to close to development
The direction of box shell 10 moves, thus, power reception part 21 and power output member 30 are easier to get detached combination.
Along rotation axis L3, outermost point P3 is than outer dead centre P2 further from rhabodoid 211, thus, above-mentioned outermost point P3, interior top
The positional relationship of point P2 and outer dead centre P3 may be summarized to be: along rotation axis L3/L21, outermost point P3 is than inner vertex P1 and outer top
Any one in point P2 is further from rhabodoid 211；As indicated in fig. 12 c, when power reception part 21 moves closer to power output member
When 30, power output member 30, which is easier to apply to power reception part 21, forces power reception part 21 to separate power output member 30
Active force, i.e. power reception part 21 are moved to the direction close to Delevoping cartridge shell 10, thus, it is defeated in power reception part 21 and power
During part 30 combines out, power reception pawl 212 is less to the interference of power output member 30, is more advantageous to power reception part 21
It is combined faster with power output member 30.
