around the sleeve 31 of the base 30 and has a distal edge not numbered a proximal edge not numbered an inside surface not numbered a hole 233 multiple teeth 231 and an optional shoulder 235 the hole 233 is formed axially through the pawl ring 23 is non circular and corresponds to the outside surface of the sleeve 31 on the base 30 so the pawl ring 23 will rotate with the sleeve 31 of the base 30 the teeth 231 are formed on and extend longitudinally from the distal edge of the pawl ring 23 the shoulder 235 is formed on the inside surface near the distal edge of the pawl ring 23 the spring 25 is mounted around the sleeve 31 of the base 30 between the pawl ring 23 and the disk 37 of the base 30 the plug 21 is mounted rotatably in the longitudinal hole 33 in the sleeve 31 of the base 30 and has a proximal end not numbered a distal end not numbered a non circular hole 211 an outer annular groove 215 at least one detent 217 and an optional circular flange 213 the non circular hole 211 is formed longitudinally in the plug 21 from the distal end the outer annular groove 215 is formed around the plug 21 near the proximal.
