Disclosed is a multi-shape combined detachable sandbox, including an upper shell and a lower shell. The detachable upper shell is arranged above the lower shell. A cavity is formed inside the lower shell. The lower shell is formed by splicing a plurality of connecting plate assemblies to form various combinations. The present disclosure has the following beneficial effects: a connector is connected to a first connecting plate, a second connecting plate, a third connecting plate, a fourth connecting plate, a fifth connecting plate and a sixth connecting plate, and a first upper shell connecting plate, a second upper shell connecting plate, a third upper shell connecting plate, and a fourth upper shell connecting plate to form various combinations of the upper shell and the lower shell. The present disclosure features simple structure, diverse changes, flexible combination and proper and simple use, and has better promotion and application.

A magnetic assembling panel includes an assembling panel and a frame for framing the assembling panel. The frame includes at least one magnetic element and a frame body having a receiving cavity receiving the magnetic element therein and a position limiting space formed at an inner edge of the frame body to receive an edge of the assembling panel. The frame includes a lower frame having a first mounting groove and a second mounting groove, and an upper frame having a third mounting groove and a fourth mounting groove. When the upper frame and the lower frame are coupled with each other, the first mounting groove and the third mounting groove form the receiving cavity to receive the magnetic element while the second mounting groove and the fourth mounting groove form the position limiting space to receive the edge of the assembling panel.
