<p>A locking device used in combination with a frame assembly, the frame assembly being provided with a first rod and a second rod, the locking device includes: a base (12) pivotally connected with the first rod; a slider (13) pivotally connected with the second rod and having a recess; a guiding pole (15) partially received within the base and the slider; a handle (11) connected with the guiding pole; and a first elastic piece (14); wherein the first elastic piece includes an elastic body received within the guiding pole, and a first bump protruded out of the guiding pole and received within the recess of the slider; when the handle is rotated, the first bump of the first elastic piece is removed from the recess of the slider in order to allow the slider being slid along the guiding pole so as to collapse the frame assembly. Alternatively, the locking device may further include a locking block which is optionally engaged with the base and used as a safety lock to prevent undesired rotation between the guiding pole and the slider.</p> |
