Abstract:
A snowfield rescue device, comprising a device housing (10), a telescopic mechanism (20), and an identification mechanism (30). The telescopic mechanism (20) is telescopically mounted in the device housing (10); the telescopic mechanism (20) comprises a plurality of elastic telescopic units (21); the plurality of elastic telescopic units (21) are sequentially connected; the identification mechanism (30) is provided at one end of the telescopic mechanism (20); each elastic telescopic unit (21) has a contraction state (21a) and an extension state (21b), and when the elastic telescopic unit (21) is in the contraction state (21a), the elastic telescopic unit (21) has elastic potential energy, and the elastic potential energy is used for driving the elastic telescopic unit (21) to be switched from the contraction state (21a) to the extension state (21b), so as to drive the identification mechanism (30) to extend out of the device housing (10). The snowfield rescue device can be convenient for a user to call for help, and saves the physical strength of the user.
