The invention discloses a portable multi-functional labor-saving screwdriver. The portable multi-functional labor-saving screwdriver comprises a 
handle; containing cavity chambers are correspondinglyarranged on the two side surfaces of the middle of the 
handle; a cavity is formed in the 
handle, a containing 
assembly is installed at the top of the cavity, a containing tube is installed at the topof the cavity, the containing tube is filled with a 
sponge block, and containing holes are formed in the top end of the 
sponge block in a centrosymmetrical mode. According to the portable multi-functional labor-saving screwdriver, the structure is scientific and reasonable, the use is safe and convenient, and the functions of labor saving, multifunction and convenient portability are realized; thelabor-saving function is achieved through the containing cavity chamber, a first rotating shaft and a booster rod; multiple screwdriver heads are convenient to collect through the containing 
assembly; the shaking of screwdriver heads is reduced in the process of collecting through the coordination of a 
rotating disc and the 
sponge block; the goal of multiple purposes of one screwdriver is achieved by replacing screw screwdriver heads; and at the same time, outlets of the screwdriver heads and 
label grooves are formed, the purpose of accurately picking up the screwdriver heads is realized by rotating the 
rotating disc, and the efficiency of picking up the screwdriver heads is improved.
