Shock absorbing adjusting structure

A shock absorbing adjusting structure comprising:

• a cylinder having a tube movably inserted into a first end of said cylinder, an end member connected to a second end of said cylinder, a passage defined radially in said end member and a central hole defined in a first side of said end member, said passage communicating with said central hole, an actuating bar rotatably inserted in said passage and a cam means located on a first end of said actuating bar, a first end of said tube adapted to be connected to a part of a bicycle frame and a second end of said tube sealed by a ring assembly which is movably engaged with an inside of said cylinder, a second side of said end member adapted to be connected to another part of the bicycle frame;
• a sleeve having a first end securely engaged with said central hole and a rod movably received in said sleeve, a second end of said sleeve movably extending through said ring assembly and located in said tube, said rod having a first end engaged with said cam means of said actuating bar and a second end of said rod being a tapered tip, and
• a piston assembly connected to a second end of said sleeve, a tapered hole defined centrally through said piston assembly and a plurality of through holes defined through said piston assembly, a pusher movably received in said piston assembly and a seal member located between said pusher and an inside of said piston assembly, a spring biased between said seal member and said pusher so as to urge said seal member to seal said through holes, said second end of said rod extending through said pusher and urging said pusher towards said tapered hole, said tapered tip of said rod movably engaged with said tapered hole.
