The second leg is pivotally connected to the first leg to switch between a folded position and an unfolded position. The extension arm which includes a restricted portion is pivotally connected to the second leg. The latching component includes a main body disposed on the second leg, and a protrusion disposed on a part of the main body opposite to the second leg. The protrusion is located inside the accommodating space to contact against the restricted portion while the second leg is switched to the unfolded position, and the protrusion is moved upon the cammed portion to separate from the restricted portion while the second leg is switched to the folded position.
