A hand truck includes a bottom base, a reinforcing member, a positing device and a handle. The bottom base consists of a U-shaped tube and a bottom plate combined vertically with a lower end of the U-shaped tube, which has two elongate side vertical portions provided with a lengthwise center hole. The reinforcing member has two side vertical tubes and two lateral rods fixed between the two side vertical tubes, which fit tightly around an intermediate section of the two side vertical portions of the U-shaped for upgrading the strength of the U-shaped tube. The position device is to stabilize the handle at an adjusted position after moved up and down and adjusted in its height relative to the U-shaped tube.

What is claimed is: 1. A hand truck comprising: a bottom base consisting of a U-shaped tube, a bottom plate and two wheels, said bottom plate combined with a lower end of said U-shaped tube in a vertical condition, said U-shaped tube having two side vertical portions of some length and a center hole formed in each said side vertical portion, a reinforcing member having two side vertical tubes and two lateral rods fixed between said two side vertical tubes, said two side vertical tubes having a center hole of a size a little larger than an outer size of said two side vertical portions of said U-shaped tube of said bottom base so that said two side vertical tubes may fit around an intermediate section of said two side vertical portions of said U-shaped tube for reinforcing strength and rigidity of said U-shaped tube; a positioning device consisting of a pull rod, a lateral rod, two side strips fixed with two ends of said lateral rod, a stop member fixed at an upper end of said two side strip, said pull rod shaped U and having two bent-outward ends to fit in a position hole in said two side vertical portions of said U-shaped tube and further in said position hole of said two side vertical portion of said U-shaped tube, said two side strips having a position hole and a fix hole for said two bent-outward ends of said pull rod to fit therein; a handle having a U-shaped handle and two elongate side vertical posts, said two elongate vertical posts provided with plural position holes spaced apart equidistantly for said two bent-outward ends of said pull rod to fit therein optionally so that said handle may be adjusted in its height and then be positioned relative to said U-shaped tube by handling said pull rod so that said two bent-outward ends may fit in said position hole of said position device, of said U-shaped tube and of said handle for stabilizing said handle at an adjusted height.
