       DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0016]    Referring to  FIG. 1  of the drawings, a bottle support with clutch control mechanism, adapted for cooperatively connected to a capping machine for performing a capping process, according to a preferred embodiment of the present invention includes a support member  1 , a first gear  2 , a housing  3  and a turntable  5 . The first gear  2  has a sleeve portion coaxially connecting to the housing  3  through a bearing  7  of the support member  1 . The first gear  2  is engaged with a second gear  6 , wherein the first gear  2  has a smaller number of teeth of the second gear  6 . In other words, the first gear  2  is a small gear compared to the second gear  6 . The housing  3 , such as a shell, is mounted to the turntable  5  through a connecting member  4  such as a screw. The support member  1 , such as a support tray for supporting a bottle thereon, has a connecting portion operatively coupled and coaxially received in the sleeve portion of the first gear  2 . Preferably, the connecting portion of the support member  1  is a sleeve portion of the support member  1  to operatively couple with the sleeve portion of the first gear  2  in a coaxial manner. A clutch  8  is provided between the connecting portion of the support member  1  and the sleeve portion of the first gear  2 . The turntable  5  is driven to rotate through the operation of a transmission device defining a moving track and a turntable axis at the center of the to turntable  5 . The support member  1  is moved along the moving track and the turntable axis of the turntable  5  while the first gear  2  is meshed with the second gear  6 . In other words, the support member  1  is rotated about the turntable axis at the center of the turntable  5 , such that the support member  1  is revolved about the turntable  5 . When the clutch  8  is engaged with the support member  1 , the support member  1  and the first gear  2  are moved together and rotated along their axes respectively. In other words, the support member  1  is driven to rotate at its center axis thereof via the rotational movement of the first gear  2 . The support member  1  is also revolved about the turntable  5 . When the clutch  8  is disengaged, the first gear  2  is rotated along its axis, while the support member  1  is no longer rotated along its axis and is only rotated with the housing  5  along the turntable axis on the moving track of the turntable  5 . The turntable  5  is an automatic turntable operated under a transmission device for rotational movement along the turntable axis. The first gear  2  is coaxially engaged with the housing  3  through the bearing  7 . The second gear  6  is actuated through the transmission device to actuate a rotational movement of the first gear  2 . In other words, the second gear  6  is driven to rotate through the transmission device in order to drive the first gear  2  to rotate. The sleeve portion of the support member  1  is received in the sleeve portion of the first gear  2  such that a support axis of the support member  1  is defined and the support member  1  is capable of having vertical and rotational movements with respect to the sleeve portion of the first gear  2 . The clutch  8  is provided between the support member  1  and the first gear  2 . When an external force is applied, the clutch  8  is engaged, the first gear  2  drives the support member  1  for having self-rotational movement along the support axis and is co-operatively work with other parts of the capping machine to perform a capping process. When the external force is released, the clutch  8  is disengaged. The first gear  2  is rotated along its first gear axis while the support member  1  is no longer driven to rotate along the support axis and is moved along with the turntable axis such that a bottle can be removed from or placed onto the support member  1 . In this embodiment, the clutch  8  has a connecting surface between the axle of the support member  1  and the sleeve portion of the first gear  2 , wherein the connecting surface can be a cone surface which is shown in  FIG. 1 , or can be a flat surface. In other words, the connecting surface can be a slanted connecting surface or a straight connecting surface. The support member  1  further provides a resilient member  9 , such as a spring, coaxially supported along the support axis of the support member  1  and a second bearing  10  provided at a bottom end of the support axis of the support member  1 , wherein an upper end of the resilient member  9  is extended towards a top support surface of the support member  1  and a bottom end of the resilient member  9  is extended towards the second bearing  10 . When a force is applied downwardly onto the support member  1 , the axis of the support member  1  acts against the force of the resilient member  9  and uses the fiction of an operative surface between the axis of the support member  1  and the sleeve portion of the first gear  2  such that the support member  1  is driven by the first gear  2  for self-rotational movement, which is rotational along the support axis of the support member  1 . When the support member  1  is having its self-rotational movement, the resilient member  9  and the second bearing  10  which is operatively connected with the resilient member  9  will then be driven to rotate together with the support member  1 . In the rotational movement of the support member  1 , the resilient member  9  is acted upon or pressed vertically only and is not acted sidewardly, wherein the resilient member  9  will only be compressed by the downward force applied on the support member  1 . In other words, torque is not exerted on the resilient member  9  and hence the support member  1  is not driven to move sidewardly or dislodge from its position. The present invention further comprises a bottom support  11 , such as a round plate, having a connecting through hole coaxially receiving and coupling a bottom end of the support member  1  along the bottle support axis in a moveable manner such that a height of the bottom support  11  relative to the first gear  2  can be adjusted, wherein an inner thread is provided at the rim surface of the through hole for assisting the height adjustment. A connecting washer  12  and a bottom fastener  13 , such as a nut, are provided for securing the bottom support  11  with the support member  1 . The bottom support  11  and the turntable  5  is arranged to move simultaneously. The hole of the connecting washer  12  is a non-circular through hole matching with the non-circular bottom end of the support member  1  such that the connecting washer  12  and the support member  1  are not rotated coaxially relative to each other. When the support member  1  is driven by the resilient member  9  for vertical movement, the connecting washer  12  which is connected to the bottom support  11  will produce a restraining effect to stop the self-rotational movement of the support member  1 . When the clutch  8  is disengaged, which is the time for removing or placing bottles, an original length of the resilient member  9  is not predictably adjustable while a height requirement of the support member  1  is strict for the operation in relation to other parts of the capping machine to perform the capping process. Therefore, the connecting washer  12  and the bottom fastener  13  can be used for height adjustment. 
         [0017]    One skilled in the art will understand that the embodiment of the present invention as shown in the drawings and described above is exemplary only and not intended to be limiting. For example, the structural design of the clutch in which the connecting surface can be a protruded surface or a protruded structure, is encompassed within the spirit and scope of the present invention.
