The invention provides split-type manually-controlled vertical moving-assistant devices, consisting of a brake handle, a brake line component, a braking mechanism, a shoe sleeve hasp, a foot plate, a rear wheel, a rear shaft, a front wheel, a front shaft and a bearing, wherein a braking mechanism is driven by the brake handle through one 'soft' brake line component. The split-type manually-controlled vertical moving-assistant device are characterized in that left and right vertical moving-assistant devices are independent, left and right brake systems are independent, and the variations of state and speed the moving-assistant devices are controlled by hands through loosening and tightening the brake handle at any position where arms can keep balance; verticality of the split-type manually-controlled vertical moving-assistant devices conforms to the human walking habit, which remove all shortcomings of riding moving-assistant tools and has the combined the advantages of environmental protection, energy conservation, safety, economy and convenience, and integrates entertainment, pleasure, fitness and practicability, hence an ideal moving-assistant tool for outgoing which can not be replaced by the prior transportation means at present.
