As shown in Figure 3D, poke rod 242 and and poke rod that shifting part 24 includes standard shaft 241, connect with standard shaft 241
The clicking section 243 of 242 connections, standard shaft 241 are rotatably installed on shell 10, and position is distinguished in standard shaft 241 and clicking section 243
In the both ends of poke rod 242；Under the action of the second elastic component, shifting part 24 is forced to be pushed into first close to rotary shaft 211
It sets, at this point, shifting part 24 is nearest from rotary shaft 211；When shifting part 24 applies active force by force protrusion 213, shifting part 24
The active force of the second elastic component is overcome to rotate to the second position far from rotary shaft 211, at this point, shifting part 24 is from rotary shaft 211
Farthest；That is, shifting part 24 can close to rotary shaft 211 first position and far from rotary shaft 211 the second position it
Between rotate, since the standard shaft 241 of shifting part 24 is rotatably installed on shell 10, clicking section 243 is centered on standard shaft 241
Rotation, specifically, the clicking section 243 of shifting part 24 is in the first position close to rotary shaft 211 and second far from rotary shaft 211
It is rotated between position；When shifting part 24 is located at close to the first position of rotary shaft 211, clicking section 243 is most from rotary shaft 211
Closely, the frizzen in equipment is oppressed in clicking section 243, and the optical path in equipment is not shielded, measure loop connection；When shifting part 24
When the second position of separate rotary shaft 211, clicking section 243 is farthest from rotary shaft 211, and clicking section 243 is no longer oppressed in equipment
Frizzen, the optical path in equipment is shielded, and measure loop is disconnected.
When the protrusion 213 that exerts a force applies active force to shifting part 24, force protrusion 213 can directly contact clicking section 243, right
For the equipment of different model, the location of frizzen in equipment is not exactly the same, therefore, if force protrusion 213
Directly contact clicking section 243, it is possible that even if clicking section 243 be pushed to by force protrusion 213 it is farthest from rotary shaft 211
When position, the frizzen in equipment is still struck the compressing of portion 243, and the optical path in equipment is still in not shielded state, also
It is to say, stroke of the clicking section 243 far from rotary shaft 211 is inadequate, leads to equipment detection failure.
As shown in Figure 3D, shifting part 24 further includes and the protruding portion 244 that contact of force protrusion 213, it is preferred that relative to group
Dynamic portion 243, protruding portion 244 closer to standard shaft 241, thus, the force protrusion 213 in rotation will first contact protruding portion 244, and
By pushing protruding portion 244 that clicking section 243 is driven to rotate to the second position far from rotary shaft 211, meanwhile, protruding portion 244
It is rotated around rotation axis L2, that is to say, that in the section vertical with rotation axis L2, clicking section 243 and protruding portion 244 are to revolve
Point where shaft axis L2 is that the center of circle constitutes concentric circles, under the premise of rotating same angle, the arc length ratio of the rotation of clicking section 243
The arc length that protruding portion 244 rotates is longer, increases the purpose that clicking section 243 rotates arc length to play, that is to say, that clicking section
2423 strokes far from rotation axis 211 are increased.
Protruding portion 244 is prominent from poke rod 242, including adjacent stress surface 244a and retaining surface 244b, when force protrusion
213 with protruding portion 244 contact when, force surface 213a is contacted with stress surface 244a first, with force protrusion 213 rotation, apply
Power face 213a is gradually disengaged with stress surface 244a, and shifting part 24 gradually moves to the second position, is completely disengaged and is connect to the two
After touch, retaining surface 244b is contacted with outer surface 213c, and shifting part 24 reaches the second position, and clicking section 243 is most from rotary shaft 211
Far；Since outer surface 213c is arcwall face, during retaining surface 244b and outer surface 213c is contacted, clicking section 243
It is always held at the position farthest from rotary shaft 211；Further, it thus can also obtain, clicking section 243 is maintained at from rotation
The time of 211 highest distance position of shaft and the arc length of outer surface 213c are positively correlated, that is to say, that and the arc length of outer surface 213c is longer,
The time that clicking section 243 is maintained at from 211 highest distance position of rotary shaft is longer, accordingly, the time that can be detected according to optical path in equipment
Length determines the arc length of outer surface 213c.
The counting process of Delevoping cartridge D is described below with reference to figure attached drawing 4A, Fig. 4 B, Fig. 5 A, Fig. 5 B, Fig. 6 A and Fig. 6 B, for more

First position, at this point, an end of the frizzen in equipment is under the contention effect of clicking section 243, another end is no longer
Optical path in screening arrangement.Before counting, tooth 233 is engaged with driving gear holding, and top surface 213a and the cover board 112 for the protrusion that exerts a force connect
Touching, spring 22 are compressed, and are counted part 21 and are in retracted mode, and force surface 213b is not contacted with stress surface 244a, at this point, combining prominent
214 entrance are played to be combined in hole 235；When starting counting, tooth 233 receive driving gear drive force gear mass 231 around
Rotation axis L1 is rotated along direction shown in r1, by the combination for combining protrusion 214 and being combined hole 235, counts part 21 by gear
The driving of body 231 is also rotated around rotation axis L1 along direction shown in r1, and force surface 213b moves closer to stress surface 244a；Work as force surface
When 213b and stress surface 244a are contacted, shifting part 24 is whole to be started to rotate around rotation axis L2 along direction shown in r2, clicking section 243
It is gradually distance from rotary shaft 211, torsional spring gradually deforms and energy accumulation.
As fig. 5 a and fig. 5b, it is kept as force surface 213a as counting part 21 is rotated to after crossing stress surface 244a
Face 244b is contacted with force protrusion outer surface 213c, and clicking section 243 reaches the second position farthest from rotary shaft 211, and is protecting
It holds in the state that face 244b contacts with outer surface 213c, the position of clicking section 243 is maintained, and shifting part 24 no longer rotates；This
When, the frizzen in equipment is no longer oppressed in clicking section 243, and frizzen returns to the position of optical path in screening arrangement, in outer surface
In the time that 213c is contacted with retaining surface 244b, spring 22 is still within compressed state, counts part 21 and remains in contracting
The state of returning.
As shown in Figure 6 A and 6 B, with the rotation for counting part 21, as the outer surface 213c and retaining surface of force protrusion
When 244b is disengaged, shifting part 24 under the elastic reset power effect of torsional spring around rotary shaft L2 along direction shown in r3 from second
