[0024] The spring 16 can extrude the clamping block 14 to extend out of the movable slot 17.

[0025] The end of the clamping block 14 away from the protective cover 5 is provided as an inclined surface.

[0026] The support plate 7 is fixedly installed on the side wall of the press body 1 below the mounting plate 6, and the upper surface of the support plate 7 and the lower surface of the protective cover 5 are matched with each other.

[0027] The support plate 7 can support the bottom of the protective cover 5, thereby improving the firmness of the protective cover 5.
