The invention discloses a cake material clamping device. The cake material clamping device comprises a clamping base, a clamping cover, a bottom plate, an elastic element and a locking piece, whereinthe clamping base is matched with the clamping cover. A cake material placing cavity is arranged in the clamping base. The clamping base and the clamping cover are detachably connected. The elastic element is detachably arranged on the side wall of the clamping cover. The clamping base is connected with the bottom plate through a pin shaft. The side wall of the bottom plate is detachably connectedwith the side wall of the clamping cover through the locking piece. Locking is achieved due to the cooperation between the locking piece and the elastic element. The elastic element is made of elastic materials. The cake material clamping device solves the problem that the whole clamping device needs to be dismounted when a prior cake material is replaced.
