A cart includes a frame having four detachable first posts and each first post has multiple grooves defined radially in the outer periphery thereof. Multiple fixing members each are a plate having a semi-circular cross section. A protrusion extends from the inner periphery of each of the fixing members so as to be engaged with the groove. Multiple pairs of the fixing members are connected to each one of the first posts. Each tray has a cone-shaped first fixing member on each of four corners thereof so as to be respectively connected to the four first posts. Each of the first posts has one wheel connected to the lower end thereof. A box is connected between the trays and includes an outer body and at least one inner body which is removably inserted into the outer body. Tools and parts are received in the inner body.
