The stroke used in patient care

After the gear motor to drive a pair of screw nut. The rotary motion of the motor into linear motion by the motor reversing complete putter action. As can complete rotation, shaking and other complex actions through a variety of levers, joystick or connecting rod and other institutions. By changing the length of the lever arm, you can increase or decrease the stroke. Stroke control device Worm Drive Type: Worm gear motor driven worm gear rotation, so that a small screw worm inside the axial movement of the connecting plate driven by a corresponding axial movement of the retainer lever, until the desired stroke by adjusting the stopper depression stroke switch off, the motor is stopped (positive and negative control the same). Gear form: the motor driven through a reduction gear mounted on the inner tube of a small screw, driven together axially connected thereto run nuts, nut antenna switch off the power when pressed to the limit set by stroke, motor Stop motion (reverse same as).
