         BACKGROUND OF THE INVENTION  
         [0002]    The conventional dolls in human or animal shape generally have fixed size. Therefore, the transportation and storage of these dolls with fixed size are serious problem, especially for large size doll.  
           [0003]    The China patent No. 2464405 discloses a toy with flexible size, which comprises a body, a resilient set, a positioning ring, and a seat. The body and the seat have arbitrary shape for mimicking human or animal. The resilient set comprises supportive plate and hollow pipes with tensile spring to provide flexible size to the toy. However, in the prior art top with flexible size, the toy needs resilient set with tensile spring, the structure thereof is complicated and the cost is increased.  
         SUMMARY OF THE INVENTION  
         [0004]    It is the object of the present invention to provide a telescopic doll structure, which can be shrunk for storage and expanded for using.  
           [0005]    To achieve above object, the present invention provides a telescopic doll structure comprising a base, a top stage, and a telescopic rack. The telescopic rack is composed of at least two hollow pipes with one pipe being able to be straightly shrunk into another pipe. The base is assembled to one end of one pipe and the top stage is assembled to one end of another pipe. At least one clamping unit is used to clamp the at least two hollow pipes when they are expanded. A figure is arranged on the top stage to enclose an exterior of the telescopic doll structure.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0021]    With reference to FIGS.  1  to  5 , the present invention provides a telescopic doll structure comprising a base  10 , a telescopic rack  20 , a top stage  30  and a FIG. 100 (with reference to FIGS. 9 and 10). The base  10  is of flat plate shape and can stand on ground for supporting the doll.  
         [0022]    The telescopic rack  20  is composed of hollow pipes with two segments or three segments. In the described embodiment, the telescopic rack  20  is composed of hollow pipes with three segments, i.e. a top pipe  21 , a middle pipe  22  and a bottom pipe  23 . The top pipe  21  can be straightly shrunk into the middle pipe  22 , and the middle pipe  22  can be straightly shrunk into the bottom pipe  23 . Moreover, the base  10  is assembled to lower end of the bottom pipe  23 , and the top stage  30  is assembled to upper end of the top pipe  21 .  
         [0023]    The middle pipe  22  is connected to a connection stage  24  on upper end thereof. A first clamping unit  25  is provided between the top pipe  21  and the middle pipe  22  and comprises a fixed stage  251 , a resilient section  252 , a clamping section  253  and a clamping hole  254  as shown in FIG. 4A. The fixed stage  251  is embedded to a lower end of the top pipe  21  and has a recess  255  concave in horizontal direction. The resilient section  252  and the clamping section  253  are arranged in the recess  255  and the clamping section  253 , for example, can be steel ball movable in the recess  255 . The clamping section  253  is arranged outside the resilient section  252  and exposes out of the fixed stage  251  due to the resilient force of the resilient section  252 . The clamping hole  254  is provided at a top portion of the middle pipe  22  and corresponding to the clamping section  253 .  
         [0024]    When the top pipe  21  is stretched from the middle pipe  22 , the clamping section  253  clamps the clamping hole  254  such that the top pipe  21  is clamped atop the middle pipe  22 . If the top pipe  21  is pressed downward, the clamping section  253  is released from the clamping hole  254  and the top pipe  21  is again shrunk into the middle pipe  22 .  
         [0025]    A second clamping unit  26  is provided between the bottom pipe  23  and the middle pipe  22  and comprises a fixed stage  261 , a resilient section  262 , a clamping section  263  and a clamping hole  264  as shown in FIG. 4B. The fixed stage  261  is embedded to a lower end of the middle pipe  22  and has a recess  265  concave in horizontal direction. The resilient section  262  and the clamping section  263  are arranged in the recess  265  and the clamping section  263 , for example, can be steel ball movable in the recess  265 . The clamping section  263  is arranged outside the resilient section  262  and exposes out of the fixed stage  261  due to the resilient force of the resilient section  262 . The clamping hole  264  is provided at a top portion of the bottom pipe  23  and corresponding to the clamping section  263 .  
         [0026]    When the middle pipe  22  is stretched from the bottom pipe  23 , the clamping section  263  clamps the clamping hole  264  such that the middle pipe  22  is clamped atop the bottom pipe  23 . If the middle pipe  22  is pressed downward, the clamping section  263  is released from the clamping hole  264  and the middle pipe  22  is again shrunk into the bottom pipe  23 . With reference to FIGS. 3, 5 and  5 A, when the middle pipe  22  is shrunk into the bottom pipe  23 , the clamping section  263  is clamped to a lower clamping hole  266  on a lower portion of the bottom pipe  23  such that the middle pipe  22  is clamped even in shrunk state.  
         [0027]    With reference to FIGS. 9 and 10, the telescopic doll structure of the present invention is assembled into a FIG. 100 with arbitrary human or animal shape. In the preferred embodiment, the FIG. 100 is a Santa Claus with bottom thereof fixed to the base and top thereof fixed to the top stage  30 . Therefore, the FIG. 100 covers the telescopic rack  20  and the top stage  30 .  
         [0028]    When the telescopic rack  20  is in a stretched state, the FIG. 100 is expanded between the base  10  and the top stage  30  as shown in FIG. 9. When the telescopic rack  20  is in a shrunk state, the FIG. 100 is collapsed as shown in FIG. 10. Therefore, the size of the FIG. 100 can be greatly reduced for the convenience of transportation and storage.  
         [0029]    With reference to FIGS. 6 and 7, a transmission means  40  is provided on the top stage  30  and comprises a motor  41 , a belt set  42 , a wheel set  43 , a link rod  44  and a swing rod  45 . The motor  41  is placed in the top stage  30  with its axis connected to the belt set  42 . The belt set  42  is linked with the wheel set  43 . The link rod  44  is connected acentricly to one wheel  431  in the wheel set  43  on one end thereof and the swing rod  45  is pivotally connected to top of the top stage  30  through a pivotal shaft  46  such that the swing rod  45  seesaws with the pivotal shaft  46  as a pivot. Another end of the link rod  44  is connected to the swing rod  45 .  
         [0030]    When the motor  41  is rotated, the power of the motor  41  is transmitted to the swing rod  45  through the belt set  42 , the wheel set  43 , and the link rod  44 . Therefore, the swing rod  45  is swung alternatively as shown in FIG. 8. The swing rod  45  drives two limbs  47  placed in arms of the FIG. 100, whereby the arms of the FIG. 100 can be swung alternatively by the swing rod  45 . When the left arm is raised, the right is down.  
         [0031]    One end of the limb  47  is pivotally assembled to a pivotal stage  48  in the swing rod  45  and connected to the top stage  30  through a pusher  49 . Moreover, a spring  50  is connected between the limb  47  and one end of the swing rod  45  to resiliently clamp the limbs  47 . When the swing rod  45  is swung alternatively, the downward moved end of the swing rod  45  drives the pusher  49  to rotate the limb  47  and raise the limb  47 . Therefore, the hand of the FIG. 100 can be raised.  
         [0032]    Although the present invention has been described with reference to the preferred embodiment thereof, it will be understood that the invention is not limited to the details thereof. Various substitutions and modifications have suggested in the foregoing description, and other will occur to those of ordinary skill in the art. Therefore, all such substitutions and modifications are intended to be embraced within the scope of the invention as defined in the appended claims.
