A fire-blocking door lock structure is mounted on a fire-blocking door including a frame member, a push handle and a casing. In particular, the invention relates to a woundbandage protector configured as a wrap, a sockmitten, or a bandage, which may be made out of stretchable material. The assembly mechanism of the printed circuit allows the module to be placed precisely on a complementary mechanism of an apparatus case, for example a wristwatch case, accommodating it to have the liquid crystal cell in a determined position in the case. The pattern is defined by two pairs of first and second intermediate deck boards, with each intermediate deck board in each pair having a second width.
