1. A holder system for a drum comprising:
a body,
an upper holding member disposed within the body,
a lower holding member disposed within the body and coupled to the upper holding member to define an adjustable opening between the upper and lower holding members,
a fastener threadedly received in the body and engageable with a surface of the upper holding member,
a holding rod having a proximal end received in the opening such that when the holding rod is in an unsecured condition when the fastener is not engaged with the holding member, the holding rod can be moved linearly and be rotated with respect to the body,
a pin received in the body and associated with a surface of the lower holding member,
a resilient, generally cylindrical split ring fixed to the body, the split ring having an adjustable bore there-through, the pin being engaged with the split ring,
first and second clamping members having portions received in the bore of the split ring so as to be rotatable with respect to the body, and
a shaft received by the first and second clamping members such that in the unsecured condition, the shaft can rotate about a longitudinal axis thereof, and rotate with respect to the body,
wherein the holder system is constructed and arranged such that when the fastener is moved to engage the upper holding member, the upper holding member is pushed by the fastener causing the opening between the holding members to reduce in size and thus causing the holding members to clamp on and prevent any movement of the holding rod and, substantially simultaneously, the lower holding member pushes on the pin which causes the bore of the split ring to reduce in size causing the split ring to clamp on the clamping members to prevent any movement of the shaft, thereby defining a secured condition of the holding rod and shaft.
