     DETAILED DESCRIPTION OF THE INVENTION 
     Referring to the power-driven device of the present invention shown in FIG. 1, its structure includes a motor  1  a shaft  2  directly connected to the motor  1 . Shaft  2  is connected to rotating shaft  1   a  of motor  1  with screw  1   b . Shaft  2  is connected to guide lever  3 , which is an intermediate mechanism that is also connected to final movable axle  6 . A washer  4  and a screw nut  5  are used for fixing the movable connection between guide lever  3  and shaft  2 . Final movable axle  6  is connected to balance weight  12 . Balance weight  12  provides for smoother and more lifelike movement of the animated wireframe. Balance weight  12  is connected to non-fixed support  8 . Non-fixed support  8  has pivot axle  6   a , which movably connects to the wireframe to allow up and down movement of a portion of the wireframe. Motor  1  is described in U.S. patent application Ser. No. 09/458,325 which is hereby incorporated by reference. 
     FIG. 2 shows the condition that the electric device shown in FIG. 1 has been arranged on wireframe  7 , which forms a part of the body of the animal-like structure. Particularly, final movable axle  6  and balance weight  12  are attached to non-fixed support  8 . Non-fixed support  8  can be arranged on wireframe  7  in a non-fixed state by movably placing pivot axle  6   a  in recepticles  6   b  located on or in wireframe  7 . This allows for up and down movement of non-fixed support  8 . FIG. 3 mainly shows the condition of decomposition of the parts shown in FIG. 2, as well as movable part  9 . Movable part  9  is connected to non-fixed support  8  with connector  9   a . Connector  9   a  is adapted to connect to support bar  8   a  of non-fixed support  8 . By way of example, connector  9   a  may be an inverted U-shape (not shown) such that the inverted U-shaped connector is placed over support bar  8   a  so that support bar  8   a  rests in the curved portion of the inverted U-shaped connector. 
     Referring to FIG. 4, in a first embodiment, the motor-driven wireframe appears generally animal-like and comprises a fixed part with a body and four limbs, and movable part  9  with a neck and a head. Motor  1  of the electric device is attached to the fixed part of the wireframe by its housing. Non-fixed support  8  of the electric device is pivotably connected to the wireframe via pivot axle  6   a  and recepticles  6   b  (not shown). Non-fixed support  8  is connected to movable part  9  via connector  9   a  which rests upon support bar  8   a , as set forth above. When the power supply is turned on, motor  1  is enabled to rotate shaft  2 , which in turn rotates guide lever  3  . When guide lever  3  rotates, it causes final shaft  6  and balance weight  12  to move up and down. The movement of final shaft  6  and balance weight  12  causes non-fixed support  8  and movable part  9  to move accordingly. As shown in FIG. 4, movable part  9  (i. e., the neck and head part of the whole animal-like wireframe) makes up-and-down movement. 
     In a second embodiment of the power-driven device of the present invention, shown in FIG. 5, non-fixed support  8  is adapted for side-to-side movement. Non-fixed support  8  is connected to final shaft or axle  6 ′ via connecting rod  6 ″. Non-fixed support  8  includes support rod  8   a  and pivot rods  8   c , which allow for side-to-side movement of the movable part of the wireframe. Guide lever  3   a  further includes bearings  14  to enable smooth rotation of final shaft  6 ′ and motor shaft  2   a  within the guide lever. Motor  1  further includes a mounting bracket  20  for affixing the motor to the fixed part of the  30  wireframe. 
     A preferred embodiment of the wireframe of the present invention, adapted for use with the power-driven device of FIG. 5, is shown in FIGS. 6 and 7. Motor  1  is mounted to a fixed part of wireframe  7  by mounting bracket  20  such that when activated, guide lever  3   a  rotates in a manner that causes final shaft  6 ′, and subsequently non-fixed support  8  and movable part  9  to move side-to-side. Non-fixed support  8  is pivotably connected to wireframe  7  by placing pivot rods  8   c  in recepticles  8   d , which allow pivot rods  8   c  to freely pivot. Movable part  9  is connected to non-fixed support  8  via connector  9   a , as described above for FIGS. 3 and 4. 
     When the power supply is turned on, motor  1  is enabled to rotate shaft  2   a , which in turn rotates guide lever  3   a . When guide lever  3   a  rotates, it causes final shaft  6 ′ to move side-to-side. The side-to-side movement of final shaft  6 ′ causes non-fixed support  8  and movable part  9  to move accordingly. As shown in FIG. 7, movable part  9  (i. e., the neck and head part of the whole animal-like wireframe) makes side-to-side movement as shown by arrow A. 
     In a third embodiment of the power-driven device of the present invention, shown in FIG. 8, non-fixed support  8  further includes balance weight  12   a  disposed between the end of non-fixed support  8  and final shaft  6 ′″. Balance weight  12   a  provides for smoother and more lifelike movement of movable part  9 . Guide lever  3   a  further includes bearings  14  to enable smooth rotation of final shaft  6 ′″ and shaft  2   b  within guide lever  3   a . Non-fixed support  8  also includes support rod  8   a  for receiving the connecting means of the movable part (not shown). Motor  1  further includes a mounting bracket  20   a  for affixing the motor to the fixed part of the wireframe. This embodiment is adapted for use in either side-to-side or up-and-down movement of non-fixed support  8 , as described above. As such, non-fixed support  8  may further include a pivot axle or pivot rods, as described above, depending on the direction of movement desired. 
     In a third embodiment of the wireframe of the present invention, shown in FIG. 9, the motor-driven wireframe appears generally angel-like. It comprises a fixed part with two arms  71 , body  72 , head  73 , and movable parts  16 , which appear wing-like. In this embodiment, movable parts  16  are adapted to move front to back in relation to the angel-like wireframe to give the appearance of flapping. The power-driven device of the angel-like wireframe is shown in FIG.  10 . Its structure includes motor  1 , mounting bracket  20 , and shaft  2   a . Motor  1  is affixed to body  72  via mounting bracket  20 . Shaft  2   a  is directly connected to motor  1  with shaft  2   a  being further connected to guide lever  3   b . Guide lever  3   b  is an intermediate mechanism connected to shaft  2   a  and final movable axle or shaft  6 ′. Guide lever  3   b  also has bearings  14  to enable smooth rotation of movable axle  6 ′ and shaft  2   a  within guide lever  3   b . Final movable axle  6 ′ is fixed upon cam  25  parallel to the axis of rotation of the cam. 
     Cam  25  is rotatably fixed on bearing  25   a  of support  26  of fixed body  72 . Cam  25  has a pair of bushings  35  affixed thereto. Bushings  35  are offset from one another along the circumference of cam  25 . Bushings  35  are adapted to rotatably affix members  28  to cam  25 . Members  28  have bushings  34  affixed thereto. Bushings  34  are adapted to rotatably affix driver arms  32  to members  28 . 
     A pair of wing rods  22  are rotatably connected to bearings  23 , which are affixed to body  72  at rods  23 ′. Wing rods  22  are parallel to one another and are parallel to the axis of rotation of cam  25 . Wing rods  22  have driver arms  32  affixed perpendicular thereto. Wing rods  22  further include connectors  40  for removably affixing movable parts  16  thereto. 
     In use, power is applied to motor  1 . Motor  1  rotates shaft  2   a , which in turn rotates guide lever  3   b . Guide lever  3   b  drives final shaft  6 ′ and thus rotates cam  25 . The rotation of cam  25  imparts an eccentric rotational movement to members  28 . The movement of members  28  causes driver arms  32  to rotate wing rods  22  in a back-and-forth motion. Thus, movable parts  16 , removably affixed to wing rods  22  at connectors  40 , appear to move in a flapping motion. 
     The present invention may also include bulbs. As a result, a wireframe that not only illuminates, but also moves, is formed.
