From combination, and gradually move along direction shown in d1, by the second through hole end face 224a and contacting of inserting block 32, induced effect bar
Lifting portion 32 the most gradually move along direction shown in d1, treat that lid door completely disengages from pressure surface 31a and contact, actuating rod 3 and power
Receiving element 21 returns to the original state shown in Fig. 6 A, it follows that the retraction process of power reception part 21 is in the resilience of extension spring 24
Can realize under power effect.At power reception part 21 by stretching out in the motor process retracted, the rotation axis L1 of photo-sensitive cell,
The rotation axis L2 of power reception the part 21 and rotation axis L3 of gear part 25 is coaxial.
[other explanations]
The present inventor is in practice, it has been found that owing to extension spring 24 is chronically at extended state, handle box C is through one section
After the use of time, the pulling force of extension spring 24 may weaken, and causes lid door during opening, and the pulling force of extension spring 24 is not enough to
Make power reception part 21 depart from power output member to combine, and then make power reception part 21 can not return to initial retraction shape
State.
The work more stable for ensureing handle box C, it is also possible to auxiliary reset part is set on handle box C, it is preferred that described
Auxiliary reset part 14 is elastic component.As shown in Figure 6A, auxiliary reset part 14 is arranged on end cap 11, and concrete is positioned at guide groove 110
In, when device cover door is closed, actuating rod 3 contacts with auxiliary reset part 14, and compresses auxiliary reset part 14.
As it has been described above, the free terminal face 31c of forced section to rotating part midpoint distance t1 with insert block 321 terminal surface arrive
Distance t2 at rotating part midpoint meets: t1 ＞ 5t2, i.e. actuating rod 3 can essentially regard a force amplification mechanism as, or
The laborsaving lever of person, when forced section 31 is by a less active force, a bigger active force will feed back in lifting portion 32.
When device cover door is opened, if the pulling force of extension spring 24 is not enough, then the insertion block 321 in lifting portion will be at auxiliary reset part 14
Restoring force effect under abut with the second through hole basal surface 224b, and in the middle of the bigger active force compressing fed back by lifting portion 32
Part 22 connects power reception part 21 and moves along direction shown in d1 together with support member 23, thus ensures that power reception part can be smooth
Return to initial retracted mode, it follows that when the pulling force deficiency of extension spring 24, the retraction process of power reception part 21 is being drawn
The common effect of spring 24, auxiliary reset part 14 and actuating rod 3 is lower to be realized.
Further, for preventing power reception part 21 during flexible, there is beat in middleware 22, the present invention implements
In example, described handle box C also includes the fixed part being disposed therein, and described fixed part supports middleware 22 for fixing, and then
The whole power transmission 2 of fixing support, it is ensured that middleware 22 keeps coaxial with power reception part 21 always.Preferably, described
Fixed part is the rib 121a being arranged on support 12, as shown in FIGURE 3 E, rib 121a along the inwall of third through-hole 124 to inwardly projecting
Going out, along the installation direction A of handle box C, described rib 121a is in the downstream of breach 120, after handle box assembles, and rib
121a is adjacent with described joint portion 222, it is furthermore preferred that described rib 121a has two and relative at the inwall of third through-hole 124
Arrange；Certainly, described fixed part is not limited to the rib 121a being arranged on support 12, it is also possible to be to revolve along it from gear part 25
Shaft axis L3 is multiple raised to extend away from photosensitive cylindrical direction, and middleware 22 is clamped between the plurality of projection, from
And ensure that middleware 22 keeps coaxial with power reception part 21 always.
As it has been described above, the actuating rod 3 in the present invention is to put in the plane including handle box longitudinal direction X and horizontal Y place
Dynamic, the initial forces of actuating rod 3 is from device cover door, when needs take out handle box C, it is only necessary to opening lid door, power connects
Addressee 21 can return to initial retracted mode in extension spring 24 or extension spring 24 under the effect with auxiliary reset part 14.
Power reception part in the embodiment of the present invention is fitted without spheroid, its rotation axis and the rotation axis of photosensitive cylinder
The most coaxial, and power reception part is integrally forming by connector with gear part, therefore, when handle box or photo-sensitive cell are in
Time in transportation, power reception part of the present invention does not haves and departs from, with gear part, the possibility combined, thus effectively protects
