Abstract
The utility model provides a lever type watch movement which is provided with a clutch disc, a crank shaft, a clutch device, a split-second transmission wheel and a minute wheel. The clutch disc is swingingly fixed on the movement body and can at least swing around a point A. The clutch disc is provided with a spring disc, a pulling claw and a clutch plate on the same side with the point A. The other end, which is opposite to the clutch disc, of the spring disc is fixed on the movement body, so that when the clutch disc rotates an angle around the point A under an external force, the spring disc has certain elastic potential energy. The pulling claw is connected with the transmission clutch device and can drive the clutch device to switch on and off when the clutch disc swings around the point A. The other end, which is opposite to the clutch disc, of the clutch plate abuts against the end part of the crank shaft, and the clutch plate can drive the clutch disc to rotate an angle around the point A when the crank shaft is pressed. According to the utility model, the shape of the clutch disc is changed; the problems that due to the fact that the end, which contacts a pulling block, of a clutch lever is long, the clutch disc is prone to deformation in a work process and the like can be effectively prevented; and the work hours of the clutch disc is greatly prolonged.

Described arrangement of clutch is provided with a shifting block; What described shifting block can swing is fixed on the movement main body, and makes it and can swing around 1 B; Described second minute power wheel is located at an end of shifting block, and by the swing realization of shifting block and engagement and the drop out of gear of minute wheel.
Described shifting block is provided with groove near clutch-plate one end, and the pusher dog of clutch-plate is stretched in the groove of shifting block, can swing around a B to drive shifting block.
It is provided with a reference column at an A place described timepiece movement, shown in clutch-plate be provided with pilot hole, and be sheathed on the reference column by pilot hole, pilot hole and the reference column of described clutch-plate satisfy interference fit.
Described clutch-plate and reference column are preferable over the arbor left side.
Usefulness:
1, this novel shape of changing clutch-plate can effectively be avoided trip(ping) lever and to set an end that contacts ahead longer, and clutch-plate in the course of the work the problems such as deformation occurs easily, has greatly prolonged the work duration of clutch-plate.
2, this Novel clutch bar is metal plain film position, does not need repeatedly to amount to, and can effectively avoid in manufacturing process because amounting to the improper clutch part generation non-reversible deformation that causes, the frequency of minimizing replacing parts.
3, this is novel by arrangement of clutch being set under the effect that utilizes lever principle, control second minute power wheel and minute wheel meshes and drop out of gear, then realize pulling needle to the time and the purpose of transmission when walking.
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, in order to better understand the utility model scope.

Embodiment
Embodiment 1:
A kind of lever wrist-watch movement as shown in Figure 1 can solve the easily distortion in making or use procedure of existing timepiece movement clutch part, and it comprises clutch-plate 1, arbor 2, arrangement of clutch 3, second minute power wheel 4 and minute wheel 5; What described clutch-plate 1 can swing is fixed on the movement main body 6, and makes it can swing around an A at least, and described clutch-plate 1 is provided with shell fragment 11, pusher dog 12 and clutch plate 13 in an A the same side; Described arrangement of clutch 3 is provided with a shifting block 3 '; What described shifting block 3 ' can swing is fixed on the movement main body 6, and makes it and can swing around 1 B; Described second minute power wheel 4 is located at an end of shifting block 3 ', and by the swing realization of shifting block 3 ' and engagement and the drop out of gear of minute wheel 5.
It is provided with a reference column 7 at an A place described timepiece movement, shown in clutch-plate 1 be provided with pilot hole 8, and be sheathed on the reference column 7 by pilot hole 8, pilot hole 8 and the reference column 7 of described clutch-plate 1 satisfy interference fit.
Described clutch-plate 1 and reference column 7 are preferable over arbor 2 left sides.
The disclosed clutch-plate 1 of the utility model embodiment is metal plain film shape, only arranges porosely at clutch-plate, does not amount to, and serviceable life is longer; And the clutch-plate manufacture craft of plain film shape is comparatively simple, and the making qualification rate is higher.
Principle of work:
Such as Fig. 1, Fig. 2 and shown in Figure 3, described shell fragment is fixed on the movement main body with respect to the other end of clutch-plate 1 so that when clutch-plate 1 because being subjected to external force when some A rotates an angle, shell fragment can have certain elastic potential energy, and by elastic potential energy, make clutch-plate have restorable trend; Described pusher dog 12 connection for transmission arrangement of clutch, and satisfy clutch-plate when an A swings, but the Kai Heguan of driving clutch; Described clutch plate leans with arbor 2 ends mutually with respect to the other end of clutch-plate, and satisfy and to promote clutch-plate when pressing arbor 2 and rotate an angle around an A, because the arbor head has a side force to clutch plate 13 when promoting arbor 2, force the shifting block right half down to rotate to an angle, divide the minute wheel 5 on power wheel 4 and the movement main body to be in engagement the second that is installed in like this on the shifting block 3 ' right half; When pull-out piece, clutch-plate is reset to state of nature, and the shifting block right half up rotates to an angle, and second minute power wheel 4 and minute wheel 5 are in the drop out of gear state, when movement stops to walk, can carry out pulling needle to the time.
Drive connection is: promotion arbor → clutch-plate → set ahead → second minute power wheel → minute wheel.
Arrangement of clutch among the embodiment 1 provides a kind of thinking, obviously also can adopt centering block or other unit of plastics.
It also can set a device according to actual needs at an A place timepiece movement described in the embodiment 1, such as locating slot or orientable parts.
The utility model has utilized leverage, realize second minute power wheel 4 and minute wheel 5 engagement and drop out of gears, reach pulling needle to the time and the purpose of transmission when walking, clutch-plate shape, position have also effectively been utilized simultaneously, effectively avoid trip(ping) lever and to set an end that contacts ahead longer, the problems such as deformation occur in clutch-plate in the course of the work easily, have greatly prolonged the work duration of clutch-plate; And be reduced in the manufacturing process because amounting to the improper clutch part generation non-reversible deformation that causes, the frequency of minimizing replacing parts.
This first novel goal of the invention is: this novel existing timepiece movement clutch part of a kind of solution that provides holds yielding problem in making or use procedure; More than be for preferred embodiment of the present utility model; the description that the utility model is carried out; those skilled in the art should do some suitable change within not breaking away from spirit and scope of the present utility model, it all belongs in the scope that the utility model appended claims asks for protection.
