The device further includes a telescoping plunger assembly, the assembly including at least a frontmost member, a rearmost member and at least one intervening member which can be in the nature of a turnbuckle. At least a portion of the plunger assembly is connected to the base. A motor is provided for rotating the turnbuckle of the telescoping plunger assembly, and there is also a fast rewinder comprising a turnbuckle splitter whereby the turnbuckle splits longitudinally into two halves. The device additionally includes a plunger biassing mechanism whereby the telescoping plunger assembly can be manually compacted against the resistive force of two or more plunger biassing springs.
