Based on the embodiments only in the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present invention.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be implemented in other ways different from the specific details set forth herein, and one skilled in the art may similarly generalize the present invention without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.

As shown in fig. 1 to 3, a gum spreader comprises an elastic sheet 1, wherein the elastic sheet 1 is of an arc-shaped structure, two ends of the elastic sheet are respectively connected with a connecting sheet 2, a holding part 3 is respectively fixed at the connecting part, the connecting sheet 2 is of an arc-shaped structure which is in a buckling state with the elastic sheet 1, a shielding sheet 4 is fixed at the other end which is not connected with the elastic sheet 1, and the two shielding sheets 4 are arranged in parallel.

The shielding sheet 4 comprises a fixing portion 41 and an inserting portion 42, the fixing portion 41 is connected with the connecting sheet 2, an inserting hole 411 is formed in the unconnected end of the fixing portion along the length direction of the connecting sheet, an inserting rod 421 matched with the inserting hole 411 is fixed on the inserting portion 42 in a direction towards the fixing portion 41, a plurality of limiting assemblies 43 are arranged on the surface of the inserting rod 421 in an array mode, each limiting assembly 43 comprises a limiting block 431 and a connecting spring 432 connecting the limiting block 431 with the inserting rod 421, the connecting spring 432 is perpendicular to the surface of the inserting rod 421, the limiting block 431 is an arc-shaped block body, the arc surface of the limiting block 431 faces the surface of the fixing portion 41 close to the limiting block 431, and a plurality of limiting grooves 412 matched with the arc-shaped surface of the limiting block 431. A fixing hook 5 is fixed on the outward facing surface of the fixing portion 41 and the insertion portion 42. The fixing hook 5 is a cylindrical structure, an injection hole 50 is formed in the middle of the fixing hook 5 located on the fixing portion 41 along the length direction of the fixing hook, and the injection hole 50 penetrates through the outer wall of the fixing portion 41.
