Abstract

L'invention porte sur une structure de fixation destinée à fixer un premier appareil et un second appareil l'un à l'autre, ledit second appareil devant être fixé au premier appareil. La structure de fixation comprend : une section protubérante qui est formée sur le premier appareil et qui fait saillie sur la surface du premier appareil ; un élément de pression qui est situé sur le premier appareil et qui applique une force de pression qui presse la section protubérante dans la direction allant du premier appareil au second appareil ; une section en renfoncement qui est formée dans le second appareil et dans laquelle la section protubérante doit être introduite. La section en renfoncement comprend : un trou d'introduction, dans lequel la section protubérante peut être introduite ; un trou de glissement, formé de façon continue à partir du trou d'introduction, qui retient la section protubérante de telle sorte que cette dernière peut coulisser à l'intérieur du trou, et qui est incliné de telle sorte que la force de pression s'accroît lorsque la section protubérante glisse à partir du trou d'introduction.
