Base plate;

The sidewall that vertically extends from described base plate both sides and form;

Be positioned on described base plate and the box body being connected with sidewall or base plate, in described box body, be equiped with the sliding part for ejecting card pallet.

As the structure of a kind of optimization of the present utility model, described box body and sidewall or base plate laser welding.

As the structure of a kind of optimization of the present utility model, the length of described box body is consistent with the length of described sidewall.

As the structure of a kind of optimization of the present utility model, the length range of described box body is 1～2mm.

As the structure of a kind of optimization of the present utility model, described sliding part comprises elastomeric element and the snap fit being connected with elastomeric element.

As the structure of a kind of optimization of the present utility model, described box body is the rectangular shape of hollow.

As the structure of a kind of optimization of the present utility model, described box body is without bottom surface; Described box body and described base plate are formed for holding the accommodation space of sliding part.

As mentioned above, Kato dish fixed structure of the present utility model, has following beneficial effect:

Adopt Split type laser welded structure, by laser welding, base plate or sidewall and box body are welded into an integral body, can realize sliding part and slide very swimmingly in box body inside, frictional force is little, thereby the life-spans that can make Kato dish reach thousands of times plug.

The Kato dish fixed structure that the utility model provides is comparatively simple, low to the required precision of mould, punching is good; And, without riveting, laser welding is fixed in factory, and is used interchangeably, be beneficial to the expansion of family's series of products.
