A device for batting and striking practice having a base assembly to provide a firm support, said device comprising:

• a lower tube having an upper threaded end and a lower threaded end, said lower threaded end being threadedly engaged to said base assembly;
• a centrally bored sleeve being cylindrical in shape, said sleeve having an internally threaded end at a lower section thereof while an upper section being tapered to a slightly narrower bored section, said sleeve engaging with said upper threaded end of said lower tube at said internally threaded end;
• a set of cylindrical packing rings being fitted within said sleeve, said packing rings being centrally bored to releasably secure an intermediate tube;
• said intermediate tube being slidably inserted through said sleeve, said set of packing rings and said lower tube;
• said packing rings being compressed within the sleeve to contract about said intermediate tube when said sleeve threadedly engages with the lower tube;
• said intermediate tube having a tapered head at one end thereof for securely mounting a spring;
• said intermediate tube being of sufficient length to afford a range of height adjustments;
• a cylindrical protective housing being centrally bored to receive said spring, said protective housing having a center hole at the lower surface thereof to accommodate said intermediate tube, said head of said intermediate tube being pressable into a lower portion of said spring secured by the tension of said spring;
• a body assembly for practicing batting or striking being mounted on said protective housing, said body assembly being engaged with a bolt interconnects between said body assembly and an upper portion of said spring.
