Being installed with Magnet a on described pedal, described vehicle body two sides are installed with control device, control device corresponding with the Magnet a position on the pedal of collapsed state；The described device that controls includes that an opening is towards the plastic material outside vehicle body or the housing of the groove body type of aluminum alloy material, the opening inner side of housing is installed with the Magnet b of annular, the bottom of housing is installed with the Magnet c of annular, the magnetic direction of Magnet b is identical with Magnet a, and the magnetic direction of Magnet c is contrary with Magnet a；An armature it is slidably fitted with in housing, described armature includes pedal control portion, commutation adhesive portion and the antivibrator connecting portion that one connects successively, described pedal control portion through Magnet b and does not contacts with Magnet b inner circumferential, described commutation adhesive portion is slidably connected with inner walls, and commutation adhesive portion both ends of the surface can be attracted with Magnet b, Magnet c respectively；Described antivibrator connecting portion periphery is arranged with the spring of an aluminum alloy materials, and the two ends of spring are limited between commutation adhesive portion and housing bottom, the external diameter of the spring internal diameter less than Magnet c；It is connected between described antivibrator connecting portion and the bottom of housing and has one in order to the straight line one-way damper slowing down spring reset speed；When described commutation adhesive portion is attracted with Magnet c, the outer end in described pedal control portion exceeds the Magnet b end face near shell nozzle, and the repulsion between Magnet a and the magnetic field of armature is more than the suction between Magnet a and armature itself；
The magnetic force of described Magnet b and Magnet c is 5000-6000 Gauss, and the magnetic force of Magnet a is 2000-3000 Gauss；
Form to connect the connection recess of straight line one-way damper on described antivibrator connecting portion；
Distance between described Magnet b and Magnet c is than the big 5-15mm of thickness in commutation adhesive portion；
When described spring is in extended configuration, the commutation adhesive portion of armature is attracted with Magnet b, owing to the magnetic direction of Magnet b is identical with Magnet a, armature is magnetized jointly by Magnet b and Magnet a, the magnetic direction of armature is identical with Magnet a, the pedal control portion of armature of electromagnet is attracted with the Magnet a on pedal, so that pedal is fixed on collapsed state；When needs use wheelbarrow, can be by hand or foot's pressing pedal, so that pedal promotes armature to be inwardly indented, the commutation adhesive portion that spring is compressed into armature is attracted with Magnet c, owing to the magnetic direction of Magnet c is contrary with Magnet a, commutation adhesive portion and pedal control portion on armature are magnetized by Magnet c and Magnet a respectively, as long as the suction between armature and Magnet c is more than the suction between Magnet a and armature, so, i.e. produce mutual exclusion between armature and Magnet a, thus force pedal rotate and change to deployed condition under self gravitation effect.
