A handcart is composed of a body, a lifter and a coupler. The body has two parallel rails connected together by a crosspiece integrated at rear ends of the support boards, two front wheels respectively provided beneath front ends of the rails, and two elongated bars respectively provided beneath the rear ends of the rails. The lifter is provided at the rear end of the body. The lifter has a hydraulic bar and a handle side by side and uprightly provided at a top thereof, and a rear wheel provided thereunder. The coupler connecting the body and the lifter together is detachably and pivotally mounted between the body and the lifter. Whereby, when the coupler is damaged, it is very easy for a user to replace the coupler with a new one.
