Beschreibung
Zusammenfassung:	The utility model discloses a mechanism for prolonging the service life of a tensioner spring, which comprises a fixed seat and a tensioning assembly arranged on the fixed seat, the tensioning assembly consists of a first tensioning assembly and a second tensioning assembly, and the first tensioning assembly and the second tensioning assembly are symmetrically arranged on the fixed seat; the first tensioning assembly comprises a first control arm and a first belt wheel arranged below the first control arm. The second tensioning assembly comprises a second control arm and a second belt wheel arranged below the second control arm. The first control arm and the second control arm are connected through a spring, the spring is located above the first belt wheel and the second belt wheel, and the first belt wheel and the second belt wheel are used for providing tensile force for the first control arm and the second control arm so that the spring can bear the tensile force of the first control arm and the second con
