1. A chassis quick release device, comprising:
a housing comprising a base and a cover that are capable of being combined with each other, said base comprising a sliding channel and an accommodating space connected to each other;
a locking block combined in said accommodating space and movable linearly; and
an operating handle, said operating handle comprising a rod body positioned on said sliding channel, said rod body being assembled with a grip, said rod body comprising a cylindrical joint corresponding to said grip, said cylindrical joint defining therein a shaft groove, said grip being provided with a sleeve corresponding to said cylindrical joint, said sleeve defining therein an accommodating cavity;
wherein through the structure of the chassis quick release device, said grip is capable of producing rotational steering on said rod body to facilitate pulling out of a preset chassis; when moving said operating handle in a direction of said housing, said locking block makes a linear movement in a first direction and slides out from said accommodating space to form a locked state; when pulling said operating handle away from said housing, said locking block makes a linear movement in a second direction to form an unlocked state, and
wherein said base further comprises a compression space in said sliding channel and said accommodating space, said compression space being further provided with a resistance wall for one end of at least one linear reset member to resist, each said linear reset member having an opposite end thereof held against a resisting plate radially extending from said rod body to provide a reset force for said operating handle to move toward said housing, each said linear reset member is a spring.
