The invention relates to a three degree-of-freedom self-stabilizing box body grab bucket based on a parallel mechanism. The grab bucket comprises the three degree-of-freedom parallel mechanism, a fixing plate, four electric slide tracks and four machine claws, wherein the three degree-of-freedom parallel mechanism is arranged right above the fixing plate, and connected with the fixing plate through bolts; the fixing plate adopts a square structure; the electric slide tracks are respectively arranged on the four top angular bisectors of the fixing plate and are fixedly connected with the fixing plate; the machine claws are respectively mounted under the electric slide tracks. The space motion states of the grab bucket can be realized by controlling the rising, falling, speed changing and stopping operation of an electric push rod; the three degree-of-freedom parallel mechanism adopting a 3-RPS mode can perform motion in one translating direction and two rotating directions, namely three degree of freedom directions; the control is simple; the motion property is excellent; the stability in box body grabbing is enhanced; the box body is prevented from shaking in a conveying or lifting process.
