Conventionally, for the quartz watch only with two gear adjusting functions of time-division second hand, as shown in Figure 1, only a clutch comprised arbor 1, trip(ping) lever 2, stopped a second electrode 3, minute wheel 62, second wheel 63, third wheel 4, back gear 41, trip(ping) lever limited post 71, bottom plate 91, train wheel bridge 92 and control circuit board 93 second for it, wherein:

The indication of arbor 1 minute hand during for adjusting timekeeper, as Fig. 1, shown in 2, arbor 1 is shaped as rod major axis, encircle its major axis circumferential wall and be interval with two grooves 12, each groove 12 is one grade, during adjusting, transmission wheel 13 used is nested with on arbor 1, when needs regulate the time, arbor 1 is pulled out outward and (take Fig. 1 as reference direction along its axle sleeve, to upper left for pushing, to bottom right for pulling out outward), arbor back stop 14 with regard to holding in corresponding groove 12, simultaneously, outer arbor 1 front end and transmission wheel 13 wringing fits of dialling, the swing handle 11 of rotation arbor 1 outer end is rotatable corresponding transmission wheel 13 adjustings that realize time-division pointer indicating position by the back gear 41 being meshed with transmission wheel 13, when completing adjusting and do not need to adjust again, arbor 1 is pushed in along its axle sleeve to watchcase, transmission wheel 13 departs from wringing fit state with arbor 1 front end, state while recovering normally to walk, now, even if rotate the swing handle 11 of arbor 1 outer end, can not make transmission wheel 13 rotate with it yet, that is to say and can not make described time-division pointer position change thereupon.

Trip(ping) lever 2 is in movement system, all the time keep being electrically connected to arbor 1, positive plate and anode, trip(ping) lever 2 is also used for when adjusting time-division pointer, make the only second end of control circuit board 93 chips in set state, make chip stop sending and driving electric pulse (being that motor stops operating) to the motor of controlling second wheel 63 rotations, when adjusting time-division pointer position, second wheel 63 stops operating; When not needing to regulate the time-division during pointer, state when arbor 1 is recovered normally to walk, the only second end of control circuit board 93 chips is just in original reset state, and chip recovers to send and drive electric pulse (being that motor starts to rotate) to described motor, now, second wheel 63 recovers again to rotate.

Trip(ping) lever 2 is by the rotary power spring 21 that produces elastic force, with trip(ping) lever limited post 71 or principal arm 22 that only second electrode 3 touches mutually, drive to stop second clutch banking stop 23 of arm 27 rotational displacement and can be pushed away the only second arm 27 that touches and be shifted by arbor 1 front end and form, described clutch banking stop 23 is a complete slice, a described only second arm 27 is atresia strip, trip(ping) lever 2 is disjunctor member, to be made by the elastic sheet metal conducting electricity, in principal arm 22 and rotary power spring 21 junctions, be provided with rotary shaft hole 83, trip(ping) lever 2 is nested with on the trip(ping) lever turning axle 81 being fixed on bottom plate 91 by these rotary shaft hole 83 rotations, the free end of described rotary power spring 21 (that one end not being connected with principal arm 22) is to stirring also holding away from principal arm 22 directions on the power fulcrum 82 being fixed on bottom plate 91, make it to principal arm 22, impose the power of rotation, the power of this rotation can make principal arm 22 rotate around trip(ping) lever turning axle 81 counterclockwise (take Fig. 2 as reference direction), described clutch limited post 71 is located at that the outside of principal arm 22 front ends is other (take Fig. 2 as reference direction, the lower left of trip(ping) lever 2 principal arms 22 is outside, its upper right side is inner side), otherly in the inner side of principal arm 22 inner ends be provided with that only second electrode 3(is common, only a second electrode 3 is column), in clutch banking stop 23 and the joint of principal arm 22 front ends, be also provided with axle hole 5, when principal arm 22 is rotated counterclockwise, the inner side of principal arm 22 inner ends will second, an electrode 3 touches (referring to Fig. 3) with only, now, principal arm 22 is thrown off with trip(ping) lever limited post 71, otherwise, when principal arm 22 turns clockwise (take Fig. 2 as reference direction) (referring to Fig. 2), the outside of principal arm 22 front ends will touch with trip(ping) lever limited post 71, now, principal arm 22 and only second electrode 3 disengagements.

Only second electrode 3 is for controlling the rotation of described motor or stopping, when principal arm 22 is when only second electrode 3 touches mutually, as previously mentioned, the only second end of control circuit board 93 chips is in set state, chip stops sending and driving electric pulse (being that motor stops operating) to the motor of controlling second wheel 63 rotations, and second wheel 63 stops operating; Otherwise when principal arm 22 is when only second electrode 3 disconnects, as previously mentioned, the only second end of control circuit board 93 chips is just in original reset state, chip recovers to send driving electric pulse to described motor, and motor starts to rotate, and second wheel 63 recovers again rotation.

Hour wheel 61, minute wheel 62, the mutual collocated of second wheel 63, they are connected with hour hands, minute hand and second hand respectively through bottom plate 91 one end of axle separately, the upper end of second wheel 63 axles is placed in the axis hole of train wheel bridge 92 correspondences, described third wheel 4 is arranged between second wheel 63 and minute wheel 62, the upper end of third wheel 4 axles is also placed in the axis hole of train wheel bridge 92 correspondences, the lower end of third wheel 4 axles is placed in crossing in axle hole 5 of arranging on trip(ping) lever 2, connected mode is therebetween: the axle tooth external toothing of the dish tooth of third wheel 4 and second wheel 63, the dish tooth external toothing of the axle tooth of third wheel 4 and minute wheel 62;

When pulling out arbor 1 outward, need to regulate the time-division during pointer, arbor 1 front end departs from and stops contacting of second arm 27, as previously mentioned, under the effect of rotary power spring 21, trip(ping) lever 2 is with only second electrode 3 is tactile mutually, simultaneously, under the displacement of trip(ping) lever 2, the lower end of third wheel 4 axles also produces displacement, causes the dish tooth of its axle tooth and minute wheel 62 to depart from engagement, thus, make being in transmission connection of second wheel 63 disconnections and minute wheel 62;

Bottom plate 91 and train wheel bridge 92 are accurately located for part in fixing various tables;

Control circuit board 93 is used for providing or disconnecting the electrical connection controller of power to drive disk assembly.

As shown in Figure 3, when needs regulate the time-division during pointer, arbor 1 is outwards extracted to a segment distance, now, the front end of arbor 1 and only second arm 27 disengagements, owing to losing the support of arbor 1, with second rigidly connected clutch banking stop 23 of arm 27 only, principal arm 22, under the effect of rotary power spring 21, the trip(ping) lever turning axle 81 of take is rotated counterclockwise as axle, principal arm 22 drive clutch banking stops 23 disengagings contact with trip(ping) lever limited post 71, the counterclockwise displacement of clutch banking stop 23, drive again the displacement of third wheel 4 axle lower ends on it, cause third wheel 4 axle teeth to depart from the external toothing of coiling teeth with minute wheel 62, that is to say minute wheel 62 and second wheel 63 disengagements (be beneficial to and regulate minute hour hands), simultaneously, the inner side of principal arm 22 inner ends is with only second electrode 3 is tactile mutually, make control circuit board 93 chips stop sending driving electric pulse to described motor.

As shown in Figure 2, when completing the adjusting of this time-division pointer, arbor 1 is pushed into bottom in shell, the front end that is about to arbor 1 touches and stops second arm 27 and make it along arbor 1 axial advancement, (take Fig. 2 as reference direction, be left reach), drive principal arms 22 to overcome the elastic force of rotary power spring 21 with the rigidly connected clutch banking stop 23 of second arm 27 only, around trip(ping) lever turning axle 81, turn clockwise, in like manner, its result departs from principal arm 22 and stops contacting of second electrode 3, make control circuit board 93 chips recover to send driving electric pulse to described motor, simultaneously, under trip(ping) lever limited post 71 spacing, third wheel 4 axle teeth also coil the accurate external toothing of tooth with minute wheel 62, thus, recover second wheel 63, being in transmission connection of minute wheel 62 and hour wheel 61.

Said structure has the following disadvantages:

1) owing to being subject to space constraint in shell, arbor 1 is restricted to the degree of depth pushing in shell, being that the axial stroke of arbor 1 is too short (pushes and too deeply can make an only second arm 27 be pushed to the parts that touch other, affecting clock and watch normally works), thus, limited the possibility of the more adjusting timekeeper functions of expansion on the arbor 1 of finite length.

2) only a second electrode 3 is touch type with contacting of trip(ping) lever 2 principal arms 22, As time goes on, only a second electrode 3 can be polluted or be oxidized, this can cause principal arm 22 and stop the electrical connection properties variation between second electrode 3, make control circuit board 93 chips at principal arm 22 when only second electrode 3 touches mutually, can not make the only second reliable set of end of control circuit board 93 chips, can not stop sending and driving electric pulse to motor, thereby lose only second function, this not only consume battery power (transportation or storage period, in order to save the energy content of battery, outer the pulling out of arbor 1 need to be made to motor in stop state), and when adjusting time-division pointer, third wheel 4 can tilt (while dialling outside arbor 1, the lower end of the axle of third wheel 4 can be outward-dipping due to the displacement of clutch banking stop 23), now, all the time the second wheel 63 rotating can damage the teeth of its axle tooth and third wheel 4 dish tooth external toothing parts.

Summary of the invention

The technical problem to be solved in the present invention is to provide only second clutch of a kind of many gears clock and watch, it can be in the situation that only improving second functional reliability, the axial stroke that improves arbor, the finite space making full use of in watchcase is developed the possibility of more clock function and adjusting thereof.

Embodiment

As shown in Fig. 4,6, many gears clock and watch of the present invention are a second clutch only, comprises the trip(ping) lever 2 of being made (can be stainless steel substrates, metal copper sheet or electrical conductivity alloy sheet) by the elastic sheet metal conducting electricity, arbor 1, is attached to the only second electrode 3 on control circuit board 93, wherein

Trip(ping) lever 2 is by rotary power spring 21, principal arm 22, clutch banking stop 23 and only second, an arm 27 formed, and clutch banking stop 23 unlike the prior art, its two parts that arranged by separation form, a part is for keeping reed 25, keep the root of reed 25 and principal arm 22 disjunctors of trip(ping) lever 2, its end is free end; Another part is positioning reed 24, the root of positioning reed 24 also with principal arm 22 disjunctors of trip(ping) lever 2, its end is all free end, and keeps the main part of reed 25 and positioning reed 24 isolated by U-shaped breach 26.Described maintenance reed 25, due to the conjoined structure of its root and principal arm 22, makes it keep the feature that is rigidly connected therebetween, again due to the U-shaped breach 26 of itself and 24 existence of positioning reed, makes it have again space stressed and that swing, has flexible feature.

The free end that keeps reed 25 be connected be shaped as rectangular and with the made only second arm 27 of trip(ping) lever 2 same materials, at 85-95 degree, (this angle refers to that arbor 1 is when insertion is arranged in the eccentric orfice 28 stopping on second arm to the angle that only axis of second arm 27 and arbor 1 forms, the angle only forming between second arm and arbor 1 axis, the arbor 1 that this angle is described after this scope is beneficial to inserts in eccentric orfice 28), be preferably 90 degree, only on second arm 27, be provided with eccentric orfice 28, eccentric orfice 28 be shaped as circle, square or oval, also can be the unlimited breach of a side, the hole heart of eccentric orfice 28 departs from arbor 1 axis and at this arbor 1 axis and keep between reed 25, this eccentric orfice 28 can make arbor 1 when deeply pushing away in shell, make arbor 1 front end be placed through in this eccentric orfice 28.Owing to having set up this eccentric orfice 28, thereby can effectively increase arbor 1 to the length of stroke pushing in shell, that is to say, in arbor 1 situation of same length, to prior art, arbor 1 only has two states, and arbor 1 front end and only second arm 27 disengaged condition (an only second state) and arbor 1 front end touch and make its front shifting state (state when recovery is normally walked) mutually with a second arm 27 only, if deeply can make again an only second arm 27 touch other parts, cause the damage of other parts; And for the present invention, arbor 1 can have a plurality of states, and arbor 1 front end and a second arm 27 only throw off that (an only second state), arbor 1 front end touch and move forward (motor recovers to rotate the state that regulates) with a second arm 27 only completely, arbor 1 front end pushes in eccentric orfice 28 (adjusting two-state) and continue to go deep into (state when recovery is normally walked) etc.This shows, on second arm 27 only, set up eccentric orfice 28 and can on the arbor 1 in finite length, expand to many grades of clock and watch governor motions.

When clock and watch are normally used (to clock and watch when regulating), arbor 1 is positioned at recovery state while normally walking, be that arbor 1 main part pushes watchcase interior (only having the swing handle 11 of arbor 1 to be placed in outside watchcase) completely, now, the front end of arbor 1 inserts in described eccentric orfice 28 in deep process, eccentric orfice 28 produces displacement, its hole heart falls on the axis of arbor 1, thereupon, the displacement that only 27 tractions of second arm keep reed 25 to produce towards arbor 1 direction, again due to the position-limiting action of 71 pairs of principal arms 22 of trip(ping) lever limited post, keep reed 25 just to present certain elastic deformation, the elastic performance of maintenance reed 25 now in action.

As shown in Figure 7,8, when adjusting timekeeper, need to, by outer group of arbor 1, divide again following two kinds of situations:

1) arbor 1 front end is transferred to from eccentric orfice 28, and still with only second arm 27 is tactile mutually for its front end face

Although eccentric orfice 28 departs from the constraining force of arbor 1, keeping under the flexible effect of reed 25, the eccentric orfice 28 hole hearts depart from arbor 1 axis, eccentric orfice 28 is got back to original position, under the support of arbor 1 front end face, because stopping a second arm 27, keep reed 25, being rigidly connected between principal arm 22, make principal arm 22 still rest on the state contacting with trip(ping) lever limited post 71, it is third wheel 4, between second wheel 63 and minute wheel 62, still remain on normal engagement, now, only a second electrode 3 not yet contacts with trip(ping) lever 2, only second function is inoperative, therefore the motor of controlling second wheel 63 rotations can not stop operating.

2) arbor 1 front end face departs from and stops contacting of second arm 27

Arbor 1 continues outer pulling out to second, an arm 27 departed from completely with only, under the effect of rotary power spring 21, principal arm 22 can drive and keep reed 25 and stop a second arm 27 being rotated counterclockwise as previously mentioned, now, principal arm 22 disengagings contact with trip(ping) lever limited post 71, and its inner side is with only second electrode 3 is tactile mutually, now, only a second function manifests, and the motor of controlling second wheel 63 rotations stops operating.

Another improvement of the present invention is to move to arbor 1 front end away from keeping by a side of reed 25 by being positioned at the other only second electrode 3 in principal arm 22 inner ends inner sides in prior art, only a second electrode 3 is attached on control circuit board 93, its shape is square or circular, by conductive metal sheet or the coat of metal, made, its position is in the lower surface of control circuit board 93, corresponding with it, at the front end of second arm 27 only, be provided with the friction-type conduction that can touch with second electrode 3 only or throw off and touch sheet 29, it is made by having flexible sheet metal that this friction-type conduction touches sheet 29, it is when only second electrode 3 touches mutually, can impose small elastic pressure to stopping a second electrode 3, outside arbor 1, pulling out to its front end face departs from second only during the contacting of arm 27, this friction-type conduction touches sheet 29 meetings being rotated counterclockwise with only second electrode 3 is tactile mutually with principal arm 22, thereby, the motor of controlling second wheel 63 rotations is stopped operating, be that second wheel 63 stops operating, equally, while recovering normally to walk along with arbor 1, friction-type conduction touches sheet 29 and also departs from and stop contacting of second electrode 3, make motor recover to rotate, second wheel 63 also recovers to rotate thus.This improvement due to friction-type conduction touch sheet 29 and a second electrode 3 only touch mutually into friction-type tactile mutually, thereby can reduce the contact resistance because only second electrode 3 surface contaminations or oxidation produce, thereby make clock and watch in storage and transport process, because stopping the only second function-stable of second electrode 3, reliably extend the serviceable life of battery.

Further improvement of the present invention is at described arbor 1 front end by the side near described positioning reed 24, also be provided with limited block 72, this limited block 72 is when positioning reed 24 is rotated counterclockwise to desired location with principal arm 22, can touch mutually with the end of positioning reed 24, its effect be the rotation of restriction principal arm 22 excessively, avoid second arm 27 only be positioned at arbor 1 foremost described transmission wheel 13 touch mutually too quickly and cause damage.

Embodiment mono-

As shown in Figure 4,5, the arbor 1 in this example can be the arbor 1 with two gear regulating powers, the adjusting of two functions when adjustable minute hand hour hands indicating positions and recovery are normally walked.

Arbor 1 front end in this example is shaped as the dumb-bell shape (be called for short to hang and draw plug-in type) with chamfering, be that the part point diameter that inserts in eccentric orfice 28 of arbor 1 is large, rear end diameter is little, the effect of chamfering is when the inside propelling of arbor 1 is goed deep into, being convenient to its front end inserts in described eccentric orfice 28, dumb-bell shape is arbor 1 front end of being convenient to insert in eccentric orfice 28, when pulling out outside arbor 1 and preparing to regulate during minute hand indicating positions, impose outside pulling force (to 21 1 power-assisteds of rotary power spring) to an only second arm 27, being convenient to friction-type conduction touches sheet 29 second electrode 3 is tactile mutually in time with only.

Embodiment bis-

As shown in Fig. 6,7,8, in this example, arbor 1 can be the arbor 1 with three gear adjusting functions, and adjustable timesharing pin, Zhou Li go through the adjusting of three functions when showing and recovering normally to walk.

Arbor 1 front end in this example is shaped as cylindrical (being called for short level and smooth plug-in type) with chamfering, be that the section diameter that inserts in eccentric orfice 28 of arbor 1 is identical, the effect of chamfering is when the inside propelling of arbor 1 is goed deep into, being convenient to its front end inserts in described eccentric orfice 28, cylindrical is that arbor 1 front end of being convenient to insert in eccentric orfice 28 continues deeply to enter next function regulation stall, on arbor 1, be provided with three grooves 12, be socketed with transmission wheel 13 and dial and go through wheel 15, when needs regulate time-division pointer position or regulate Zhou Li to go through demonstration, can be by 14 holdings of arbor back stop in corresponding groove 12 and the swing handle 11 that rotates arbor 1 end regulate.

At this, it should be noted that, the radius of appropriate design eccentric orfice 28 and arbor 1 front end, can make to have inserted the arbor 1 in eccentric orfice 28, in continuing deep process, can not change and stop second arm 27 in the position perpendicular in arbor 1 plane, guarantee contacting of trip(ping) lever 1 and trip(ping) lever limited post 71, at tune, last the normally timing of time-division second hand guaranteeing
