gear belt chain or other known mechanisms to transmit motion actuating motor 206 rotates sleeve 203 through a pre designed gear ratio and rods 201 and 202 move with respect to one other motor 206 can be controlled by a printed circuit 208 which may include without limitation at least one of a micro controller radio system remote switch capacitor and induction coil the power source to activate the motor can be a battery 207 the electrical components may be controlled by an external unit via remote control radio light voice etc alternatively as shown in the embodiment of fig6 second rod 202 does not have to be moved by the actuating motor instead second rod 202 can be attached to or part of housing 209 the actuating motor moves first rod 201 towards or away from second rod 202 instead of being electrically actuated actuating motor 206 can be hydraulic or pneumatic and this option is illustrated in fig6 actuating motor 206 includes a fluid operated hydraulic or pneumatic piston 220 operated by a fluid hydraulic or pneumatic pump 222 connected thereto by a tube 224 fig6 also shows the option that at least one of the rods 201 or 202 may be.
