[0040] The usage and working principle of this device are as follows: When it is necessary to pull out one of the drawer bodies 109, the cabinet door 105 is opened by using the handle 107. After opening, one set of anti-slip pads 119 is swung by the pivot 120. When swung, they disengage from the corresponding drawer body 109, and the second compression spring 116 loses its restraining force. The slide bar 115 changes its state, and the top plate 117 uses its elasticity to push the corresponding drawer body 109 forward, making it easy for the user to pull the drawer body 109 outward by using the pull plate 123. While the drawer body 109 is being pulled outward, the slider 124 can slide on the limit rod 112 under force, and the first compression spring 113 changes its state under force. In this state, the support roller 122 rolls under force. After the operation is completed, the user releases the pull plate 123, and the drawer body 109 can be moved into the cabinet 101 by the elastic force of the first compression spring 113, with the reverse side contacting the front side 117 of the top plate. The slide bar 115 and the second compression spring 116 change their own state under force. Then the user presses the drawer body 109 backward. When it is pressed to the appropriate position, the anti-slip pad 119 swings through the pivot 120. When it swings to the vertical state, it can restrict the drawer body 109 and keep it stably in the cabinet 101. With the cooperation of multiple factors, it can effectively avoid cabinet door collisions or safety problems caused by forgetting to push the drawer back, thus improving the convenience and safety of use.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
