From Fig. 1 Yi and second shown in Figure 2, the utility model Zhu is Yaoed You base body (1), dynamical system (2) Yi and movement device (3) and is consisted of as can be known, base body wherein (1) Wei Yi Zhong sky box body, just can accommodating dynamical system (2) Yu actuation gear (3) etc. member; And be located at the upper power supply room of base plate (11) (12), and which is provided with several locating dowels (121), can supply the location of dynamical system (2) Yu locking.

Zai person, dynamical system (2) You flooring plate (21), upper frame plate (22), motor (23) Yi and gear teeth wheels (24) are consisted of; Wherein Zhi flooring plate (21), upper frame plate (22) are equipped with some Zhuan Zhou locating holes on it, and Yi passes through Yu for each Zhuan Zhou (241) and locates Yong; And the upper frame plate of Yu (22) in addition End face more is provided with several shores (221), but and the proper bottom of contact Zhu guiding Zhuan dish (31), Yong Yi Zhi support guiding Zhuan dish (31), Xuan Zhuan reposefully can not compress institute Yin Yao bar (333) and elevating lever (342) Zhi and rock.

Motor (23); Then via the change of power transmission, deceleration and the direction of rotation of change-speed gearing group (24), and then obtain suitable rotating speed direction of rotation when, with power resources as actuation gear (3).

In addition, actuation gear (3) then is made of guiding rotating disk (31), disc (32), performance doll (33) and dancing doll (34), guiding rotating disk (31) wherein (please consulting Fig. 3 again), be one discoid, the center is provided with the sleeve joint hole (311) that runs through, so as with rotating shaft (241) pivot bush unit; And, be provided with the guide channel (312) that is irregular how much sealing tracks in its end face periphery, with path as guiding rocking bar (333) walking, and the usefulness that it is waved; In addition in the appropriate position of guiding rotating disk (31) end face, then be provided with one projection again and be the riser guide (313) of level and smooth fluctuating, with as the usefulness that guides elevating lever (342) Up-and-down; And, then be provided with a driven gear (314) in the short column at guiding rotating disk (31) bottom centre place, so as to receiving the power that transmits by dynamical system (2).

It is one discoid that disc (32), profile are, and down protrudes an inserting column (321) in its centre, and be drilled with inserting hole, for combining with rotating shaft (241) socket of dynamical system (2); Correspond to the position of guiding rotating disk (31) riser guide (313) in addition in disc (32) end face, up be convexly equipped with a location axle sleeve (322) that is provided with perforation, with support and location as elevating lever (342).

Play doll (33), mainly be made of movable upper body (331), the fixed lower part of the body (332) and rocking bar (333), the wherein fixed lower part of the body (332) is to be fixed on the disc (32), its centre then is drilled with a perforation, and runs through disc (32); And rocking bar (333) be " " shape; the bottom then forms an abutting part (334); just can insert the guide channel (312) of guiding rotating disk (31); and the in addition end of rocking bar (333) then can be penetrated by the bottom of disc (32), and up passed by the perforation at the fixed lower part of the body (332) center; combines with movable upper body (331) grafting; so, can form one when rocking bar (333) when waving, and movable upper body (331) also will rock the performance doll (33) that waves thereupon.

Dancing doll (34) is the doll that a tool is made the dancing shape, be provided with a register hole (341) in its bottom centre, just can with the through hole of the location axle sleeve (322) of disc (32), allow elevating lever (342) by on the riser guide (313) that is pressed against guiding rotating disk (31).

Please consult Fig. 4 again, this figure is the schematic diagram of actuating of actuation gear (3), and rotating shaft (241) the clearance socket of guiding rotating disk (31) wherein and dynamical system (2) is so can be along with rotating shaft (241) rotation; And its rotary power source, then by the driven gear (314) of being located at the bottom, receive the power that is transmitted from change-speed gearing group (24) by idle pulley (242), and by the effect of idle pulley (242), and the direction of rotation of order guiding rotating disk (31) is just opposite with rotating shaft (241); And disc (32) is because of fixedly sleeved with rotating shaft (241), thus with rotating shaft (241) rotation synchronously, and turn to unanimity; So, can cause the guiding rotating disk (31) and the relative reverse rotation of disc (32).In view of the above, the abutting part (334) of rocking bar (333) will be along the guided slidable of guide channel (312), and because guide channel (312) is random geometry, and the abutting part (334) that makes rocking bar (333) is made the relative angular displacement that corresponds to rocking bar (333) and disc (32) clearance socket place, and the angular displacement that Shi Erwei is leading, the angular displacement of Shi Erwei backwardness (promptly as shown in Figure 3), make rocking bar (333) play pendulum, also feasible jointly movable upper body (a 331) left side of playing doll (33), wave on the right side, and make the similar action that plays an instrument.

In addition, elevating lever (342) also will compress riser guide (313) and smoothly move, and height rises and falls (as shown in Figure 4) along with the geometry of riser guide (313), also makes dancing doll (34) fluctuating fluctuated indefinite jointly, just as dancing lightly.
