  "textContent": "The present invention discloses a brake handle device and an electric tractor. The brake handle device includes a seat body, a microswitch, a wrench and an elastic piece, wherein the microswitch is electrically connected with a driving motor and a power supply, and includes a main body part and a braking part; the main body part is arranged on the seat body; the braking part extends into the main body part and can elastically expand and contract relative to the main body part; the wrench is rotatably arranged on the seat body and can be abutted against the braking part; and the elastic piece is arranged on the seat body and connected with the wrench. The wrench is held to drive the wrench to rotate in the direction close to a handlebar, so that the wrench presses the braking part into the main body part for a preset length, thereby controlling the microswitch to conduct the electric connection between the power supply and the driving motor; and the wrench is released to make the wrench rotate and reset in the direction far from the handlebar under the driving of an elastic force of the elastic piece and to separate the wrench from the braking part, so that the braking part is elastically reset relative to the main body part, thereby controlling the microswitch to disconnect the electric connection between the power supply and the driving motor.",
