In this work, a labor-saving round spade improved structure is created.It includes: a shovel of earth plate,One pivot seat,One step on the pedal,One connecting rod,1. Hold the hook.A combination of control components,The control component comprises an operating rod and a clamping member.The end of the operating rod is arranged after passing through the connecting rod.The pivoting seat is assembled and positioned at the same time.The front end of the operating rod extends between the connecting rod and the holding hook.It can be pulled to move the lever upward.And therefore drive the clamping part out of the positioning.The pedal can be applied with foot force,Make the spade swing relative to the connecting rod and turn up the soil.Then grasp the connecting rod by hand.The grip handle is applied with force to shovel up the soil.It can change the force application mode by hand and foot.The function of making force application and operation easy.本創作一種省力圓鍬改良結構，其包括：一鏟土板、一樞接座、一踩踏板、一連接桿、一握持勾把、一操控組件所組合而成，其操控組件包括一操作桿與一卡持件，該操作桿末端穿設通過該連接桿後、組接該樞接座並同時進行定位，該操作桿前端伸出於該連接桿與該握持勾把之間，可以被拉動而使該操作桿向上位移，並因此帶動該卡持件脫離該定位，則得以腳施力於該踩踏板上，使該鏟土板可以相對於該連接桿旋擺並將泥土翻起，接著再以手抓握於該連接桿、該握持勾把上施力鏟起泥土，達到可以手腳搭配變換施力方式、使施力及操作容易的功用。
