BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention is related to a movable mechanical doll, and more particularly to a doll that has movable shoulders and arms driven by a mechanism and motors. 
     2. Description of Related Art 
     Dolls have been a favorite toy for thousands of years. In conventional dolls, movable mechanical dolls are much more interesting than static dolls, because these movable mechanical dolls have movable body parts and can sing and speak. However, there is no mechanical doll that can move its shoulders and arms. 
     Therefore, the invention provides an improved movable mechanical doll to mitigate and/or obviate the aforementioned problems. 
     SUMMARY OF THE INVENTION 
     The main objective of the invention is to provide a movable mechanical doll that has movable shoulders and arms. 
     Another objective of the invention is to provide a movable mechanical doll that has a mouth which can be opened and closed.

     Two arms ( 35 ) are respectively provided on the rotating joints ( 30 ) and each have a distal end ( 351 ) respectively secured in gaps ( 321 ) in the fastening members ( 32 ). Thus, the arms ( 35 ) can be moved along with the rotating joints ( 30 ). 
     Referring to FIGS. 2 and 7, the head part ( 40 ) is mounted on the first tube ( 15 ) of the seat ( 10 ). The head part ( 40 ) has a second gear box ( 41 ) having a bottom tube ( 412 ) engaged with the first tube ( 15 ). An axle ( 431 ) is received in the bottom tube ( 412 ) of the second gear box ( 41 ) and mounted with a series of gears ( 43 ) and driven by a second motor ( 411 ). 
     A lower disk ( 44 ) is rotatably mounted at a top of the second gear box ( 41 ) and has a first central hole ( 441 ) defined therethrough. The axle ( 431 ) extends through the first central hole ( 441 ) of the lower disk ( 44 ) and can drive the lower disk ( 44 ) to rotate. Two first lugs ( 442 ) are formed at diametrically opposite sides of the first central hole ( 441 ). 
     An upper disk ( 45 ) is provided above the lower disk ( 44 ) and has a second central hole ( 453 ) defined therethrough. Two arcuate slots ( 451 ,  452 ) are defined at diametrically opposite sides of the second central hole ( 453 ). The axle ( 431 ) extends through the second central hole ( 453 ) of the upper disk ( 45 ). The first lugs ( 442 ) extend in the arcuate slots ( 451 ,  452 ). A plurality of second lugs ( 454 ) is formed on the upper disk ( 45 ) and around the second central hole ( 453 ). The upper disk ( 45 ) can be rotated along with the lower disk.( 44 ) when the first lugs ( 442 ) arrive at ends of the arcuate slots ( 451 ,  452 ). 
     A head joint ( 46 ) is provided above the upper disk ( 45 ). A plurality of lug holes ( 461 ) is defined through a bottom of the head joint ( 46 ) for receiving the second lugs ( 454 ) on the upper disk ( 45 ). A neck ( 47 ) is mounted on the head joint ( 46 ). 
     Referring to FIGS. 3 and 4, when the first motor ( 22 ) is actuated, the wheel ( 23 ) is driven to move the swing rod ( 28 ). The left shoulder joint ( 26 ) connected with the swing rod ( 28 ) is moved left and right. The second link assembly is then transversally moved along with the left shoulder joint ( 26 ) and the first link assembly is driven to move by the lower linkages ( 25 ). The right shoulder joint ( 26 ) connected with the first link assembly is moved left and right. Thus, the hollow body ( 50 ) mounted on the shoulder joints ( 26 ) is moved left and right along with the shoulder joints ( 26 ). 
     Referring to FIGS. 5 and 6, when the pins ( 27 ) are moved along with the shoulder joints ( 26 ), the tubular rods ( 311 ) are moved upwards and downwards. Thus, the L-shaped plates ( 31 ) are moved forwards and backwards and pivoted about the respective pins ( 27 ). The arms ( 35 ) on the plates ( 31 ) are swung according to the L-shaped plates ( 31 ). 
     Referring to FIGS. 7 and 8, when the second motor ( 411 ) is actuated, the axle ( 431 ) is driven by the series of gears ( 43 ) to rotate. The lower disk ( 44 ) is rotated along with the axle ( 431 ). When the first lugs ( 442 ) arrive at the ends of the arcuate slots ( 451 ,  452 ), the upper disk ( 45 ), the head joint ( 46 ) and the neck ( 47 ) can be rotated along with the lower disk ( 44 ). Therefore, the headpiece ( 60 ) mounted on the neck ( 47 ) can be rotated. 
     Referring to FIGS. 9 and 10, the headpiece ( 60 ) has a mouth (not numbered) defined therein and a control device ( 70 ) to open the mouth is mounted in the headpiece ( 60 ). The control device ( 70 ) has a third motor ( 71 ), and a dragline ( 72 ) attached on an output axle of the third motor ( 71 ). A lever ( 73 ) is pivotally mounted in the mouth. The dragline ( 72 ) is attached with a rear end of the lever ( 73 ), and a front end of the lever ( 73 ) is combined with a lower lip of the mouth. A resilient member ( 74 ) is provided under the front end of the lever ( 73 ). 
     When the third motor ( 71 ) is actuated to pull the dragline ( 72 ), the mouth is closed, as shown in FIG.  10 . When the third motor ( 71 ) is actuated to loosen the dragline ( 72 ), under the force of the resilient member ( 74 ), the mouth is opened.
