It is lockable pedal height to unclamp height adjustment button.
Board component is fixed in above-mentioned bracing wire can multiple structural forms, preferably with leverage, i.e. bracing wire fixed plate
Component includes fixed mount and lever, and fixed mount is fixed on floor push body, and the center of lever is hinged on fixed mount, lever
One end be provided with roller, for height adjustment snap fit, the other end of lever is connected with bracing wire.
Further improving is：Bracing wire is fixed to be additionally provided with for adjusting the elastic bracing wire nut of bracing wire and being used on board component
The locking nut of bracing wire is locked, bracing wire nut is stuck in the neck of fixed mount, bracing wire nut and locking nut connect with bracing wire screw thread
Connect.
Above-mentioned link gear can drive guide pad to move using timing belt, i.e.,：Link gear includes connecting rod and cunning
Wheel group, assembly pulley includes movable pulley and fixed pulley；Connecting rod is hinged on floor push body at its center, one end of connecting rod with
Gas spring piston rod is hinged, and the other end is provided with movable pulley, and fixed pulley is arranged on floor push body, is placed with assembly pulley
Timing belt, the two ends of synchronous pulley are connected respectively at two guide pads.The assembly pulley and timing belt can also use sprocket wheel and chain
Bar is substituted.
In order that pedal is moved up and down more steadily, described fixed pulley and guide pad is preferably arranged symmetrically.
The utility model has the advantages that：The lift drive mechanism of floor push uses air pressure inside spring as driving source,
Pedal height adjustable is realized, whole device is integrated in inside floor push, save space.
