A kind of modularity crutch,System includes a handle body； Its internal system is provided with a light emitting device； One body of rod,It is the fixed what handle body bottom end of screw lock； And what body of rod inside system is provided with a guiding device,When inside guiding device setting what body of rod,And make to define an accommodating space at the body of rod inner upper； And a power supply unit,At the accommodating space of system's setting what body of rod,The power supply unit system couples at the light emitting device of the what handle body and makees electrical connection,And the power supply unit system to for should the light emitting device of handle body and the guiding device what of the body of rod irradiate when required electric power； Thereby,Light beam is generated using the light emitting device for opening the handle body and is projected outward,So that the walking of what night has illumination functions and user is allowed to be able to see road surface clearly； It generates light beam when the guiding device of the pressing body of rod again and conducts refraction,Cause the body of rod that luminance is integrally presented,So that the walking of what night has alarm function and is easier to be noticeable； In order to the modularity crutch with illumination and alarm function when reaching the walking use of what night.一種模組化拐杖，係包含一握把體；其內部係設置有一發光裝置；一桿體，係螺鎖固定於該握把體底端處；並於該桿體內部係設置有一導光裝置，當該導光裝置設置於該桿體內部時，而使該桿體內部上方處界定出一容置空間；及一供電裝置，係設置於該桿體之容置空間處，該供電裝置係耦接於該握把體之發光裝置處且作電性連結，而該供電裝置係用以供應該握把體之發光裝置與該桿體之導光裝置於照射時所需的電力；藉此，利用開啟該握把體之發光裝置而產生光束並向外投射，以便於夜間行走具有照明功能而讓使用者得以看清路面；又該按壓該桿體之導光裝置時而產生光束並傳導折射，致使該桿體整體呈現發光狀態，以便於夜間行走具有警示功能而較容易被察覺；俾達到於夜間行走使用時具有照明及警示功能之模組化拐杖。
