The invention relates to a manual feeding machine for steel strips. The manual feeding machine for steel strips comprises a machine frame and a steel strip roll core. The steel strip roll core is erected on the machine frame. A manual driving device is arranged on a first supporting rod. A sleeve is fixed on the first supporting rod. A transmission rod penetrates through the sleeve. A hand wheel is fixed to one end of the transmission rod, and a first positioning disc is fixed at the other end of the transmission rod. The first positioning disc is located in a limiting groove, and meanwhile a second positioning disc connected with the steel strip roll core is arranged in the limiting groove. A fastener is arranged between the first positioning disc and the second positioning disc and comprises a hinge base, a bolt and a nut, the hinge base is fixed on the first positioning disc, a notch is formed in the outer edge of the second positioning disc, one end of the bolt is hinged to the hinge base, and the other end of the bolt strides the notch and then is fixed to the nut. The manual driving device and the steel strip roll core on the machine frame are locked, so that the steel strip roll core is conveniently rotated through the hand wheel, fingers are prevented from being cut, and safety is improved in the feeding process of steel strips.
