Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-6, the present invention provides a technical solution: a telescopic ceramic knife comprises a shell 1 and a moving block 2, wherein the shell 1 is a plastic shell, and the moving block 2 is connected in the shell 1 in a sliding manner;

the elastic pressing plate is characterized in that a strip-shaped opening 3 is formed in the shell 1, first limiting grooves 4 are symmetrically formed in two sides of the strip-shaped opening 3 at equal intervals, an elastic pressing plate 5 is integrally formed on the upper surface of the moving block 2, the upper surface of the elastic pressing plate 5 is arranged in a concave manner, anti-skidding threads 15 are formed in the upper surface of the elastic pressing plate 5, pressing of finger parts is facilitated, sliding plates 6 are symmetrically welded on two sides of the elastic pressing plate 5, the lower surface of the elastic pressing plate 5 can be prevented from being in edge contact with the strip-shaped opening 3 when the elastic pressing plate 5 is pressed down, resistance borne by the elastic pressing plate 5 during;
