     Taiwan Patent 101104153, entitled Massage device capable of two-dimensional movement, is directed to a massage device comprising a first reinforced motor and a second reinforced motor. The first reinforced motor provides lateral movement-oriented power and massage-oriented power. The second reinforced motor provides vertical movement-oriented power. However, a conventional reinforced motor incurs high cost, not to mention two reinforced motors. Hence, there is still room for improvement in Taiwan Patent 101104153. 
     Taiwan Patent 101114000 is entitled Massage device capable of lateral and vertical tapping. Taiwan Patent 102202905 is entitled Massager capable of synchronous kneading and tapping. Both require at least two reinforced motors. Hence, the prior art most requires multiple reinforced motor massagers and thus still has room for improvement. 
     Three reinforced motors are required to allow conventional massage parts and components to perform six functions, namely synchronous kneading/swinging/tapping or single fixed-point kneading/swinging/tapping. However, the conventional three reinforced motors incur high cost. Furthermore, the conventional three reinforced motors operate synchronously and thus produce noise.

     Referring to  FIG. 1  through  FIG. 16 , the present invention provides an extensible device capable of switch, control, power and connection and comprises at least one extensible device  10  and a massage device  20 . 
     The at least one extensible device  10  each comprises a signal receiving device  11 , a small power source  12 , and an extensible structure  13 . The signal receiving device  11  receives a control signal. The signal receiving device  11  is electrically connected to the small power source  12  to control the small power source  12 . The small power source  12  is power-connected to the extensible structure  13 . The extensible structure  13  comprises an extensible transmission rod  131 , and a transmission gear train  132  is fixed to the extensible transmission rod  131 . 
     The massage device  20  only requires one reinforced motor  21 . The reinforced motor  21  is adapted to controllably effect a plurality of massage techniques in conjunction with the at least one extensible device  10 . 
     In an embodiment of the present invention, the small power source  12  comprises a small motor  121 , a small gear  122 , a crank  123  or a cam and a lever  124 . The small motor  121  has a worm gear  1211  for driving the small gear  122 . The small gear  122  drives the crank  123  or the cam. The crank  123  drives the lever  124 . The lever  124  drives the extensible transmission rod  131 . 
     In another embodiment of the present invention, the small power source.  12  is a small motor for driving a worm drive. A cord has one end fixed to the worm drive and the other end fixed to the extensible transmission rod  131 . The extensible transmission rod  131  is pushed outward with a spring. The small motor operates and enables the cord to be wound inward and thereby pulling the extensible transmission rod  131  inward. 
     The small power source  12  further comprises a solenoid valve and a solenoid valve shaft. The solenoid valve operates to push and pull the solenoid valve shaft, and, then, the solenoid valve shaft pushes and pulls the extensible transmission rod  131 . 
     In yet another embodiment of the present invention, the small power source  12  is a hydraulic cylinder or a pneumatic cylinder each adapted to push and pull the extensible transmission rod  131 . 
     Referring to  FIG. 14  through  FIG. 16 , the extensible device capable of switch, control, power and connection comprises a first extensible device  10   a . The front end of the extensible transmission rod  131  of the first extensible device  10   a  is pivotally coupled to a transmission gear train  132 . Two shafts are disposed at two ends of the reinforced motor  21 , respectively. A first worm  22  and a second worm  23  are fixed to the two shafts, respectively. The transmission gear train  132  comprises a first input gear  1321  and a first output gear  1322 . The first extensible device  10   a  is power-connected to a vertical displacement structure  40 . The vertical displacement structure  40  comprises a first gear  41  and a second gear  42  which are integrally formed as well as comprises a third gear  43  and a fourth gear  44  which are integrally formed. The vertical displacement structure  40  further comprises a rack  45  fastened to a casing  30  of the massage device  20 . The first input gear  1321  meshes with the first worm  22 . The first extensible device  10   a  operates to allow the first output gear  1322  to mesh with the first gear  41 , to allow the second gear  42  to mesh with the third gear  43 , and to allow the fourth gear  44  to mesh with the rack  45 . Hence, the power generated from the reinforced motor  21  is transferred to the fourth gear  44  through the transmission gear train  132 , such that the fourth gear  44  rotationally meshes with the rack  45  to drive the massage device  20  to undergo vertical displacement in its entirety and instantly. Upon reverse operation of the first extensible device  10   a , the first output gear  1322  separates from the first gear  41 , such that the vertical displacement stops instantly. 
     Referring to  FIG. 10  through  FIG. 13 , the extensible device capable of switch, control, power and connection further comprises a second extensible device  10   b  disposed in the direction of the second worm  23  of the reinforced motor  21 . The front end of the extensible transmission rod  131  of the second extensible device  10   b  is pivotally coupled to a transmission gear train  132 . The transmission gear train  132  comprises the second input gear  1323  and a second output gear  1324 . A kneading structure  50  comprises a fifth gear  51  and a sixth gear  52  which are integrally formed, a seventh gear  53  fixed to a power shaft  54 , and two oblique structures  55  fixed to the power shaft  54 . The two oblique structures  55  each have an oblique chamber  551 . The oblique chambers  551  are pivotally coupled to two massage arms  62  of four massage heads  61 , respectively. The bottoms of the two massage arms  62  are connected to two tapping sticks  71 , respectively, such that the two massage arms  62  and the four massage heads  61  are restricted to a swinging-based kneading massage, allowing the second output gear  1324  to mesh with the fifth gear  51 , and allowing the sixth gear  52  to mesh with the seventh gear  53 . The second extensible device  10   b  operates to enable the second input gear  1323  to mesh with the second worm  23 . Hence, the reinforced motor  21  drives the power shaft  54  to rotate, such that a kneading massage begins instantly. Upon reverse operation of the second extensible device  10   b , the second input gear  1323  separates from the second worm  23 , such that the kneading massage stops instantly. 
     Referring to  FIG. 10  through  FIG. 13 , the extensible device capable of switch, control, power and connection further comprises a third extensible device  10   c . The third extensible device  10   c  engages with the first worm  22  from the other side. The front end of the extensible transmission rod  131  of the third extensible device  10   c  is pivotally coupled to a transmission gear train  132 . The transmission gear train  132  comprises the third input gear  1325  and a third output gear  1326 . The third extensible device  10   c  further comprises a tapping structure  70 . The tapping structure  70  comprises an eccentric shaft  72 . An eccentric head  73  is disposed at each of the two ends of the eccentric shaft  72  and is enclosed by a sleeve  74 . A protruding end of the sleeve  74  is pivotally connected to one end of a corresponding one of the tapping sticks  71 . The other end of the corresponding one of the tapping sticks  71  is pivotally fitted to a corresponding one of the massage arms  62  by leverage. An eighth gear  75  is fixed to the eccentric shaft  72 . The eighth gear  75  meshes with the third output gear  1326 . The third extensible device  10   c  operates to enable the third input gear  1325  to mesh with the first worm  22 . The reinforced motor  21  operates to drive the eccentric shaft  72  to rotate and thus drive the massage heads  61  to perform a tapping massage instantly. Upon reverse operation of the third extensible device  10   c , the third input gear  1325  separates from the first worm  22 , such that the tapping massage stops instantly. 
     The first extensible device  10   a , the second extensible device  10   b , the third extensible device  10   c  each start independently. Hence, the massage device  20  is capable of undergoing vertical displacement only, capable of performing a kneading massage only, or is capable of performing a tapping massage only. The first extensible device  10   a , the second extensible device  10   b , and the third extensible device  10   c  can also start simultaneously, such that the massage device  20  is capable of performing vertical displacement, a kneading massage and a tapping massage simultaneously. 
     The first extensible device  10   a  and the second extensible device  10   b  can start simultaneously, such that the massage device  20  is capable of performing vertical displacement and a kneading massage simultaneously. 
     The first extensible device  10   a  and the third extensible device  10   c  can start simultaneously, such that the massage device  20  is capable of performing vertical displacement and a tapping massage simultaneously. 
     The second extensible device  10   b  and the third extensible device  10   c  can start simultaneously, such that the massage device  20  is capable of performing a kneading massage and a tapping massage simultaneously. 
     Therefore, the extensible device capable of switch, control, power and connection according to the present invention requires one reinforced motor to controllably effect a plurality of massage techniques in conjunction with the at least one extensible device, thereby having a high industrial applicability.
