摘要

The invention is a clenching and buckling device used in a play bed which can be folded simultaneously including two bars (60), a base (50) and a joint base (10). The two opposite end journals of the said bars (60) are installed inside the base (50) and the said joint base (10) is cased outside the base (50). A press button (11) which can be pressed elastically is installed at the centre of the joint base (10). A V-shaped spring lamination (30) whose one end protrudes outside the bar (60) and which is installed in the inner wall of the end of the said bar (60) is placed inside the joint base (10). The press end of the press button (11) is pressed on the spring lamination (30) and one side of the evagination of the spring button (11) has a clenching protrusion which is outside the preinstalled hole of the tube wall of the bar (60). The said corresponding joint base (10) and base (50) have the corresponding holes and the said clenching protrusion is fastened inside the holes. Two protruding control positioning supports are installed in the position of the press button (11) opposite to the inside wall of the said joint base (10) and the said control positioning support is an integral part. The outer side of the same has the protruding triangular cone-shape protrusion (23) and the outer side of the said cone-shape protrusion (23) is the sliding slope (231).
