6 . The single-stage snow thrower of claim 5 , wherein, when the single-stage snow thrower is in a folded state, the auxiliary rod and the operating handle are configured to be griped with two hands of the user to carry the single-stage snow thrower.
7 . The single-stage snow thrower of claim 4 , further comprising a switch box, wherein two ends of the switch box are fixedly connected with the first connecting rod and the second connecting rod respectively.
8 . The single-stage snow thrower of claim 1 , further comprising:
an auxiliary rod for connecting the main body and the handle device;
wherein the main body further comprises two connecting plates for supporting a shaft of the wheels, and the first housing and the auxiliary rod are fixedly connected with the two connecting plates.
9 . The single-stage snow thrower of claim 8 , wherein the two connecting plates are made of at least one metal material.
10 . The single-stage snow thrower of claim 1 , wherein the main body comprises two battery packs for powering the electric motor.
11 . The single-stage snow thrower of claim 1 , wherein the electric motor is fixedly mounted on the mounting part, the mounting part is fixedly mounted on the first housing, and the mounting part is made of at least one metal material.
12 . The single-stage snow thrower of claim 1 , wherein the main body further comprises a protecting cover disposed outside the first housing, and the transmission mechanism is arranged between a protecting cover and the mounting part.
13 . The single-stage snow thrower of claim 12 , wherein the protecting cover is made of at least one metal material.
14 . The single-stage snow thrower of claim 12 , wherein the transmission mechanism comprises a first belt pulley, a second belt pulley and a driving belt, and the driving belt is located between the protecting cover and the mounting part.
