A transport cart includes a main body and a plurality of fixing mechanisms assembled to the main body. The main body includes a plurality of supports and a plurality of rollers. Each fixing mechanism includes a first fixing element, a rotating element coupled to the first fixing element, a slider, a connecting element, a pull rod connected to the rotating element, and an elastic element assembled to the main body. The rotating element includes a first spiral arm and a second spiral arm, the slider includes a second fixing element and a stay bar. The second spiral arm can be engaged with the connecting element, to slip the stay bar relative to the support. The elastic element resists against the pull rod, to maintain attachment between the rotating element and the corresponding support.
