A quick open structure for a tool box comprising: a body including an upper housing and a lower housing, the body also including at least one retaining portions disposed on two sides of an upper end thereof, and two bearing portions secured on two sides of a bottom end thereof;the upper housing includes at least one first chamber defined on two sides thereof, and the lower housing includes at least one second chamber defined on two sides thereof, each of the at least one first chamber including two grooves secured on two sides thereof and a limiting element extending therefrom, and each groove including an opening arranged on a rear end thereof, each of the at least one second chamber of the lower housing including a receiving member formed thereon;wherein each of the at least one first chamber of the upper housing is provided to receive a locking device which includes a pressing member and an engaging member, and the pressing member includes a larger-area press portion formed on a front end thereof and two side straps corresponding to the two grooves, and each side strap includes a hole to receive a returning spring, and the pressing member also includes two first axial rotating portions mounted on two sides of a rear end thereof, each first axial rotating portion includes a first orifice defined therein, and the engaging member includes two second axial rotating portions disposed on a rear end thereof, and each second axial portion includes a second orifice defined therein, such that a shaft is inserted into two first orifices of the two first axial rotating portions of the pressing member and two second orifices of the second axial rotating portions of the engaging member so that the pressing member and the engaging member are connected together, and the shaft includes a resilient element fixed thereon to be biased against inner surfaces of the pressing member and the engaging member, the engaging member includes a fastening block arranged on an inner surface of a front end thereof. 2. The quick open structure for the tool box as claimed in claim 1, wherein when the engaging member engages with the receiving member of the lower housing, the fastening block of the engaging member is retained in a notch of the receiving member. 3. The quick open structure for the tool box as claimed in claim 1, wherein each groove of the at least one first chamber also includes the opening arranged on a rear end thereof to connect with the returning spring. 4. The quick open structure for the tool box as claimed in claim 1, wherein the pressing member is pressed and returns back to the groove so as to be further limited by the limiting element. 5. The quick open structure for the tool box as claimed in claim 1, wherein the at least one first chamber includes a holder fixed therein, and the holder includes an elastic element secured on one side thereof corresponding to the pressing member so that when the pressing member is pressed, the elastic element abuts against the inner surface of the pressing member.
