The invention discloses a labor-saving device of a hand buggy, which relates to a hand buggy for household vegetable buying and shopping and innovates a component for saving labor. The existing household hand buggy is small in size, light in weight and capable of saving labor. However, when a user pulls the hand buggy to walk, a support of the hand buggy needs to be lifted, the hand of the user ispressed by great weight, and the heavier the pulled object is, the more strenuous the hand buggy is. The invention provides a device which is installed in the middle of a hand buggy support, the support does not need to be lifted up when the hand buggy is pulled and can be pushed by hand to move, and the labor can be saved by 80%. If an old hand buggy is used for transformation, the middle of a support of the hand buggy needs to be cut off by 55mm, the two ends (the diameter is the same as the inner diameter of a support steel pipe) of the labor-saving device of the hand buggy are inserted into the support steel pipe, holes with the same diameter are drilled in through holes of a device shaft, and machine screws with the diameter of 3mm are used for fixing.

    发明名称“手拉车省力装置”,涉及的是家庭买菜购物用手拉车,创新节省体力的构件。现有的家用手拉车,体积小重量轻,省力。但拉着走时,拉车的支架需抬起来,还有较大重量压在使用者手上,拉的东西越重越吃力。本发明提供了一种装置,安装在拉车支架中间,拉着时支架不需抬起来,可用手推着走,能省力百分之八十。如果用旧车改造,则需把旧车支架中间割掉55毫米,把“手拉车省力装置”两头(直径径与支架钢管内径相同)插进支架钢管里,在装置轴通孔处钻同样直径的孔,用3毫米直径机螺丝固定。
