Elementary cylinder 8, secondary cylinder 2, piston assembly 3 is had in cylinder shell 1;
By piston tongue 3-1 separately, piston tongue 3-1 is connected side cylinder with piston rod 5 is elementary cylinder 8 for elementary cylinder 8 and secondary cylinder 2,
The cylinder that piston tongue 3-1 does not connect piston rod 5 side is secondary cylinder 2;
Piston rod 5 one end connects piston tongue 3-1, piston rod 5 the other end coupling hook 6;
Piston tongue 3-1 there is multiple throttle orifice 3-2;
Spring 4 one end connects inside rodless side end cap 9, and the other end connects piston tongue 3-1;
The outer coupling hook 6 of rodless side end cap 9;
Piston rod 5 one end is at elementary cylinder 8, and the other end is passing bar side end cap 7 outside elementary cylinder 8.
(being mounted on by hook 6 during use is equipped with on the handle of hook, when body builder firmly pulls open, spring 4 is opened, when body builder removes firmly, at spring 4 flexible effect lower piston assembly 3 to rodless side end cap 9 one lateral movement, gas in secondary cylinder 2 is extruded in elementary cylinder 8, because the pressure of the gas be extruded increases gradually, along with the increase of secondary cylinder 2 internal pressure, two equilibrium of forces are formed with the pulling force of spring, extension spring is slowly bounced back, thus plays and make the slow resilience of spring, avoid causing danger.)
2, described piston damping formula is slow puts extension spring, it is characterized in that: described piston tongue 3-1 has 6 ~ 8 throttle orifice 3-2.
3, described piston damping formula is slow puts extension spring, it is characterized in that: the aperture of described throttle orifice 3-2 is 2 ~ 5mm.
4, described piston damping formula is slow puts extension spring, it is characterized in that: described throttle orifice 3-2 is uniformly distributed on piston tongue 3-1.
Beneficial effect
Piston damping formula is slow puts extension spring, no matter old children, all can safety body-building, avoids causing the rapid resilience of spring to cause unnecessary wounding because people that strength is little is uncontrollable.
