description The utility model provides a mechanical activation device for an external fully-sealed thermal battery and the thermal battery, the device comprises a shell with a convex structure, a first inner cavity and a threaded inner cavity which are communicated up and down are arranged in the shell, and the threaded inner cavity penetrates through the bottom of the shell; the activation assembly comprises a firing pin, a spring, an igniter cap pressing screw and a primer; wherein the firing pin and the spring are sequentially placed in the first inner cavity, and the igniter cap pressing screw assembled with primer is placed in the threaded inner cavity; and the firing pin is over against the primer. The device is connected with the thermal battery through welding, so that the thermal battery forms a sealed body, the thermal battery can be ensured to be always in a full-sealed state before and after activation, and the stability and reliability of the working voltage of the thermal battery are ensured; and meanwhile,
