     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
     The description of embodiments are described in detail according to the appended drawings hereinafter. 
     First Embodiment 
     As shown in  FIGS. 1-5 , an amusing ornament ( 1 ), having one end mounted on a rod object ( 2 ) consists essentially of a decorative housing ( 10 ); a main body ( 20 ) which couples with said housing ( 10 ); a linkage unit ( 30 A) which is partially inserted into said housing ( 10 ) and a protracting element ( 40 ), incorporated in said housing ( 10 ) is pivotally connected with the long driving link ( 31 A). 
     Said housing ( 10 ) consists of a front case ( 11 ) and a rear case ( 12 ); and two sets of sockets ( 13 ,  14 ) are disposed on the inner wall of said cases respectively for retaining said linkage unit ( 30 A). 
     The main body ( 20 ) has a seat ( 21 ) disposed on an upper portion thereof for coupling with the rear case ( 20 ). A hole ( 211 ) is set on the center of the seat ( 21 ), and a hollow tube ( 22 ) is set on the bottom of the seat ( 21 ). A connecting element ( 221 ) for coupling with said rod object ( 2 ) is disposed on a bottom portion of said tube ( 22 ). Said tube ( 22 ) also incorporates a horizontal pole ( 222 ) on its lower portion. A slot ( 23 ) for providing limited movement to the linkage unit ( 30 A) is set on a side of the seat ( 21 ). The connecting element ( 221 ) is jointed with the rod object ( 2 ) by screwing or snap-fit. 
     The linkage unit ( 30 A) includes a long driving link ( 31 A) whose a bottom portion passes through said hole ( 211 ) and is given sliding movement by inserting into the tube ( 22 ), a first driven element ( 32 ) driven by the long driving link ( 31 A), a second driven element ( 33 ) having two ends pivotally connected with the seat ( 21 ) and first driven element ( 32 ) respectively and another end coupled with the front case ( 11 ), a first elastic element ( 50 ) disposed on where the second driven element ( 33 ) pin jointed with the seat ( 22 ) for providing reciprocal movement to the second driven element ( 33 ), and a second elastic element ( 51 ) incorporated in the tube ( 22 ) for providing reciprocal movement to the long driving link ( 31 A). An arm ( 314 ) is extended form a side of said long driving link ( 31 A) for pin jointing a protracting element ( 40 ). A retainer ( 315 ) is disposed on a lower portion of said driving link ( 31 A) for retaining said elastic element ( 51 ). 
     By fixing the linkage unit ( 30 A) onto the main body ( 20 ), the housing ( 10 ) and protracting element ( 40 ) are allowed to move reciprocally. The retract/protract feature of said protracting element ( 40 ) can be linked to a element ( 2 ) having same feature, such as a retractable pen, which means that when a pen refill is protracted from the pen, said protracting element ( 40 ) is driven to expose form the housing ( 2 ), and when refill is retracted, the element ( 40 ) is also retracted into the housing ( 10 ). 
     A wave structure ( 311 ) is disposed on a side of an upper portion of the long driving link ( 31 A) for providing movement to the first driven element ( 32 ) and actuating said front case ( 11 ). A groove ( 312 ) which corresponds with said pole ( 222 ) and serves as a retainer is disposed on a side of a lower portion of the long driving link ( 31 A). Said first driven element ( 32 ) is a roller. 
     A protruding pin ( 313 ) is extended from a side of said long driving link ( 31 A) to allow user controlling the linkage unit ( 30 A). A guide slot ( 223 ) is disposed on a side wall of the tube ( 22 ) for allowing the pin ( 313 ) to pass through and limiting the movement thereof. 
     As illustrated in  FIG. 4 , the function of the ornament is described as follow: when the protruding pin ( 313 ) is pulled downwardly, the first driven element ( 32 ) rolls over the wave-like surface of structure ( 311 ). When the element ( 32 ) reaches the crest, the second driven element ( 33 ) which is pivotally connected with the element ( 32 ) forces the front case ( 11 ) to open a space for exposing the protracting element ( 40 ). The first elastic element ( 50 ) is compressed by the retainer ( 315 ) and the movement is retained when the pole ( 222 ) incorporated in the tube ( 22 ) engages the groove ( 312 ) of said driving link ( 31 A), and the front case ( 11 ) is retracted to its original position by a first elastic element ( 50 ) disposed on the second driven element ( 33 ). 
     Referring to  FIG. 5 , when the protruding pin ( 313 ) is pulled upwardly, said the pole ( 222 ) disengage the groove ( 312 ), releasing compressed elastic element ( 50 ) and pushing the retainer ( 315 ) of the long driving link ( 31 A) upwardly. The first driven element ( 32 ) is driven upward by the movement of driving link ( 31 A), causing the second driven element ( 33 ), front case ( 11 ) and first elastic element to react, retracting the protracting element ( 40 ) into the decorative housing ( 10 ). 
     An alternative form of first embodiment is shown in  FIG. 6 , the difference between the alternative form and previous embodiment is that a third driven element ( 34 ) is attached to a bottom end of the long driving link ( 31 A) to drive the rod object ( 2 ), and a groove ( 341 ) is disposed on a side of the third driven element ( 34 ) for corresponding said pole ( 222 ). Thus, the long driving link ( 31 A) will not incline during its reciprocal movement caused by the pole ( 222 ), and avoid possibility that slant link ( 31 A) damages other components. 
     A third elastic element ( 52 ) is set on where the third driven element ( 34 ) jointed with the long driving link ( 31 A) for a instant reposition of the driven element ( 34 ) when passes the pole ( 222 ). The elastic element ( 52 ) also provides a fast engagement of the groove ( 341 ) and pole ( 222 ). 
     Second Embodiment 
     As illustrated in  FIG. 7 , the second embodiment of an amusing ornament is differed from the first embodiment by having a linkage unit ( 30 B) which consists essentially of a short driving link ( 31 B) whose the bottom portion passes through said hole ( 211 ) and is given sliding movement by inserting into the tube ( 22 ), a forth driven element ( 35 ) driven by the short driving link ( 31 B), a fifth driven element ( 36 ) having three ends pin jointed with the seat ( 21 ), the forth driven element ( 35 ) and first driven element ( 32 ) respectively, a second driven element ( 33 ) having two ends pin jointed with the seat ( 21 ) and first driven element ( 32 ) respectively and another end coupled with the front case ( 11 ), a first elastic element ( 50 ) disposed on where the second driven element ( 33 ) pin jointed with the seat ( 22 ) for providing reciprocal movement to the second driven element ( 33 ), and a second elastic element ( 51 ) incorporated in the tube ( 22 ) for providing reciprocal movement to the long driving link ( 31 A). A protracting element ( 40 ) is further pivotally connected the fifth driven element ( 36 ). 
     As shown in  FIG. 5 , the protracting element ( 40 ) of the first embodiment is only partially covered by the housing ( 10 ), left a portion exposed. Thus, in the second embodiment, by linking the short driving link ( 31 B) with the first, second, fourth and fifth driven elements ( 32 ,  33 ,  35 ,  36 ), the protracting element ( 40 ) is completely hidden inside the housing ( 10 ) without altering shapes of housing ( 10 ) and protracting element ( 40 ). And with two elastic elements ( 50 ,  51 ) installed, reciprocal movements of decorative housing ( 10 ) and protracting element ( 40 ) are stabilized, and protracting element ( 40 ) is protruded sharply. 
     A groove ( 312 ) is disposed on a side of the short driving link ( 31 B) for corresponding said pole ( 222 ). A protruding pin ( 313 ) is extended from a side of said short driving link ( 31 B); and a guide slot ( 223 ) is disposed on a side wall of the tube ( 22 ) for allowing the pin ( 313 ) to pass through and securing the movement thereof. 
     As shown in  FIG. 8 , said fifth driven element ( 36 ) possesses a shape of a triangle which three vertices are pivotally connected with the seat ( 21 ), first driven element ( 32 ) and protracting element ( 40 ). One of vertex is extended to form an arm ( 361 ) for attaching said protracting element ( 40 ) and another end of said arm ( 361 ) is jointed with an end of the fourth driven element ( 35 ). Said driven element ( 35 ) can be selected from an elastic loop, a shaft or a spring. Said element ( 35 ) can reduce the displacement of the driving link ( 31 B) when passing the pole ( 222 ) of the tube ( 22 ) and stabilizes the movement. 
     Therefore, when the driving link ( 31 B) is triggered and pulled downwardly, the fourth driven element ( 35 ) is driven by said force and pulls down the arm ( 361 ) of the fifth element ( 36 ). Since the firth driven element ( 32 ) is jointed with the fifth element ( 36 ), movement of the arm ( 361 ) causes reaction of the driven element ( 32 ) and generates a force to the second driven element ( 33 ) to open the front case ( 11 ), exposing the protracting element ( 40 ) from the decorative housing ( 10 ). 
     The retraction of the protracting element ( 40 ) is illustrated in  FIG. 9 , since it is the same action in reverse, no detail description is described. 
     As shown in  FIG. 10 , an alternative variation also can be applied to the second embodiment, the alternative form differs from the previous second embodiment by including a third driven element ( 34 ) pin jointed with a bottom end of the short driving link ( 31 B) to drive the rod object ( 2 ), a groove ( 341 ) disposed on a side of the third driven element ( 34 ) for corresponding said pole ( 222 ), and a third elastic element ( 52 ) disposed on where said short driving link ( 31 B) joints with the third driven element ( 34 ) for providing reciprocal movement. 
     Since the driving link ( 31 B) is shorter than the driving link ( 31 A), the incline angle thereof should be greater therefore, and affects the operation of the ornament. By attaching said driven element ( 34 ) onto the bottom of the driving link ( 31 B), the inclination of driving link ( 31 B) is avoided and proper function of the ornament is ensured.
