• a shaft (410) having a shaft first end (420) and shaft second end (430), a shaft aperture (440) running through the shaft first end (420) along a diametric direction, a shaft rounded tip (460) disposed on the shaft second end (430), a shaft spring seat (470) disposed above the shaft rounded tip (460), wherein the shaft spring seat (470) is a protrusion, a shaft spring seat (470) disposed above the shaft rounded tip (460), wherein the shaft spring seat (470) is a recession, a spring (450) through which the shaft (410) runs until the spring (450) rests on the shaft spring seat (470) disposed above the shaft rounded tip (460), wherein the shaft spring seat (470) is effective in restricting movement of the spring (450);
• a piston (510) having a piston first end (520) and a piston second end (530), a piston surface (560) disposed on the piston second end (530), on which a piston seal (550) is attached, a piston cavity (540) formed from the piston surface (560) towards the piston first end (520), a piston shaft rest surface (570) disposed at a bottom of the piston cavity (540), a piston channel (572) centrally disposed on the piston shaft rest surface (570), a piston central point (571) centrally disposed on the piston shaft rest surface (570);
• a main cylinder (610) having a main cylinder first end (620) and a main cylinder second end (630), a main cylinder vent hole (681) disposed on a surface of the main cylinder (610) effective in relieving pressure, a plate disposed within the main cylinder (610) to form a main cylinder first cavity (660) towards the main cylinder first end (620) and a main cylinder second cavity (670) towards the main cylinder second end (630), a rim disposed at a bottom of the main cylinder first cavity (660) to form a main cylinder seal seat (690), a plurality of main cylinder air passage apertures (691) disposed within the main cylinder seal seat (690), a main cylinder depression post (671) centrally disposed at a bottom of the main cylinder second cavity (670), a main cylinder O-ring (672) disposed at the bottom of the main cylinder second cavity (670) and through which the main cylinder depression post (671) runs, a main cylinder second cavity threading (673) disposed on a wall of the main cylinder second cavity (670), a main cylinder threading (680) partially disposed on the main cylinder (610), a main cylinder lock ring (650) disposed on the main cylinder threading (680), an alternative main cylinder threading (900) partially disposed on a wall of the main cylinder first cavity (660);
• wherein the shaft (410) is disposed within the adjustment cap (310), the shaft first end (420) inserts through the adjustment cap aperture (320), the insert component (210) inserts through the shaft aperture (440) to maintain the shaft first end (430) position through the adjustment cap aperture (320), the spring (450) wrapped around the shaft (410) is compressed by and between the shaft spring seat (470) and the adjustment cap spring seat (350),
• wherein the main cylinder (610) mates with the adjustment cap (310), the piston (510) is sandwiched between the rounded shaft tip (460) and the main cylinder seal seat (690), the piston seal (550) is disposed adjacent to the main cylinder seal seat (690), the rounded shaft tip (460) rests on the piston channel (572).
