     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS  
       [0014]     The present invention will be described in detail with reference to the drawings.  
       Embodiment 1  
       [0015]      FIG. 2  shows an embodiment of the movable lamp hanger of the invention, in which the lamp hanger is designed in the shape of a frog  10 .  
         [0016]     The movable lamp hanger  10  in this embodiment includes a body  7  which has two movable portions, a head portion  100  and a tail (back) portion  400  disposed on a trunk  70  of the frog. A motor  5  that is connected with a power supply (not shown) is fixed to a support  6  mounted within the body  7 , a transmission shaft  4  connected to the motor  5  with a crank  9 . A first drive rod  1  is connected to the transmission shaft  4  with its one end, and another end thereof is connected with the head portion  100  by a first connecting bar  114 . The connecting bar  114  is connected to a lower jaw portion  1000  of the head portion  100 . As shown in  FIG. 2 , the connecting bar  114  is connected to a frame  118  of the lower jaw portion  1000 , which can drive the lower jaw portion  1000  to open or close round a rotating axis  119  with respect to an upper jaw portion  2000  of the head portion  100  of the frog. A connecting member  101  is provided to connect the first drive rod  1  to the connecting bar  114 . The connecting member  101  is a gimbal in this embodiment.  
         [0017]     A second drive rod  2  is provided to connect the transmission shaft  4  with the tail portion  400 . A second connecting bar  214  is fixed to the inside of the tail portion  400 , and is connected with the second drive rod  2  with a gimbal  201  that is connected to a frame  205  of the neck portion. In this embodiment, the body is made of plastic, and a plurality of ornamental bulbs  8  are attached to the outside of the body.  
         [0018]     Thus, when the motor  5  is energized, the transmission shaft  4  is driven to move circumferentially round the output shaft of the motor  5  by the crank  9 . The first drive rod  1  and the second drive rod  2  are respectively driven to move. The first drive rod  1  drives the first connecting bar  114  to move and to hereby draw and pull the lower jaw portion  1000  upward and downward with respect to the upper jaw portion  2000  (in the direction of an arrow a as shown in  FIG. 2 ). Meanwhile, the second drive rod  2  is driven to move circumferentially round the transmission shaft  4  and hereby to make the tail portion  400  move upward and downward with respect to a fixed frame  67  where the support  6  is mounted (in the direction of an arrow b as shown in  FIG. 2 ). Because the first drive rod  1  can be designed with a different length from the second drive rod  2 , the movement of the tail portion  400  is not synchronous to that of the lower jaw portion  1000 . Therefore, the movable lamp hanger of the invention looks like a real frog.  
         [0019]     In another embodiment of the frog-like lamp hanger of the invention as shown in  FIG. 4 , a connecting member  101  includes two annuluses  11 ,  14  perpendicular to each other. With such a structure, when the motor drives the first drive rod  1  to rotate, it will take a short time for the annulus  11  to contact the annulus  14  such that the lower jaw portion  1000  stays for the same time in the closed state or in the opened state with respect to the upper jaw portion  2000 . As a result, the lamp hanger looks very vivid.  
       Embodiment 2  
       [0020]     As shown in  FIG. 3 , a movable lamp hanger shaped like a deer  20  is provided in this embodiment. As those shown in the Embodiment 1, the lamp hanger  20  includes the hollowed body  7  which is shaped a grid configuration, a great number of small ornamental bulbs  8  are attached to the inside of the body, the motor  5  is fixed to the support  6  mounted within the body  7 , and the transmission shaft  4  is connected to the motor  5  by the crank  9 . In this embodiment, there are provided three movable portions. Besides the movable portions of the head portion and the tail portion, a movable neck portion is also provided.  
         [0021]     The first drive rod  1  is connected to the head portion  100  by two connecting bars  112  and  123 . The connecting bar  123  is connected to the head portion  100  with a gimbal  103 .  
         [0022]     The gimbal  103  is connected to a frame  105  mounted to the head portion  100 . The connecting bar  112  is respectively connected to the first drive rod  1  and the connecting bar  123  with two gimbals  101  and  102 . With such a structure, the head portion  100  of the deer can be driven to move in the direction of an arrow c as shown in  FIG. 3 .  
         [0023]     The second drive rod  2  is connected to the neck portion  200  of the deer with a gimbal  201 . The neck portion  200  connected to the head portion  100  of the deer can be driven to move forward and backward round a pivot  214  within the trunk  70  by the second drive rod  2 , (in the direction of an arrow d as shown in  FIG. 3 ).  
         [0024]     A third drive rod  3  connected to the tail portion  300  of the deer by a connecting bar  312  is provided in this embodiment. A connecting bar  312  is connected to the tail portion  300  with a pivot  302  and connected to the third drive rod  3  with a gimbal  301  disposed at the body  7 . The tail portion  300  of the deer can be driven to swing in the direction of an arrow e round the pivot  302  by the third drive rod  3 .  
         [0025]     Also referring to  FIG. 1 , when the motor  5  rotates, the three drive rods  1 ,  2 ,  3  are driven to direct the head portion  100 , the neck portion  200  and the tail portion  300  to move. Because the first drive rod  1  has a different length from the second drive rod  2  and the third rod  3 , the movement of the three movable portions in this embodiment is not synchronous.  
         [0026]     Because the body of the deer is shaped in the grip configuration, and a great number of ornamental small bulbs  8  are attached to the inside of the body, when the lamp hanger is arranged on the grass and is powered in the evening, it looks like a real deer in browsing.  
         [0027]     In another embodiment of the deer-like lamp hanger of the invention as shown in  FIG. 5 , the connecting member  101  including two annuluses  11 ,  12  perpendicular to each other which is similar to that shown in  FIG. 4  is provided. With such a structure, when the motor drives the first drive rod  1  to rotate, it will take a short time for the annulus  11  to contact the annulus  12  such that the head portion  100  stays in the lowest state or at the highest state with respect to the ground for the same time. As a result, the lamp hanger looks much vivid.
