[0002] The current telescopic storage rack has a wall bracket and a pull-out bracket that are both linked by a folding arm hinge, but the first arm of the folding arm is directly hinged to the wall bracket by a hinge pin, and the second arm of the folding arm is directly hinged to the pull-out bracket by a hinge pin. Therefore, both the wall bracket and the pull-out bracket need to be provided with a rib plate structure for punching and hinge. Since the folding arm includes a first arm and a second arm that are hinged and folded to each other, when the folding arm is fully folded, the hinge hole position between the first arm and the wall bracket and the hinge hole position between the second arm and the pull-out bracket have high requirements for position accuracy, which brings technical requirements for positioning and punching. At the same time, the rib plate structure provided for the wall bracket and the pull-out bracket is easily affected by the overall shape of the wall bracket and the pull-out bracket, and needs to extend a long distance to avoid interference with the punching equipment during punching, which leads to a decrease in the rigidity of the rib plate, and is also easy to affect the installation of the hinge pin.
