Abstract: A chassis quick release device includes a housing including a base with a connected sliding channel and accommodating space therein and a cover assembled with the base, a locking block linearly movably set in the accommodating space, and an operating handle having a rod body positioned on the sliding channel and a grip assembled with the rod body. The rod body has a cylindrical joint that corresponds to the grip and has a shaft groove defined therein. The grip is provided with a sleeve corresponding to the cylindrical joint and defining therein an accommodating cavity.
