  • Patent number: 12326167
    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. Moving the operating handle in the direction of the housing causes the locking block to slide out from the accommodating space to form a locked state.
