Abstract
The present disclosure relates to a fuel supply device, comprising a fuel tank, a controller, a base and a fuel nozzle. The controller is connected to the mounting part of the fuel tank through an elastic engagement unit: the elastic engagement unit includes a pre-compressed elastic element and a boss. During installation, pressing the controller causes the boss to retract and snap into the recessed groove, while the elastic element releases radial resilience force to drive the boss to continuously press against the groove wall, forming a vibration-resistant self-locking fixation.

A fuel supply device, comprising:
- a fuel tank provided with at least one recessed groove;
- and
- a controller comprising a base, an elastic element and a boss driven by the elastic element;
- wherein the controller is detachably fixed to the fuel tank by snapping the boss into the recessed groove, and the elastic element generates a continuous resilience force after the boss is snapped into the recessed groove, ensuring tight contact between the boss and the recessed groove to achieve self-tightening fixation.

A fuel supply device, comprising:
- a fuel tank provided with at least one recessed groove;
- and
- a controller comprising a base;
- wherein at least one fixed chamber is provided on an inner bottom wall of the base, and an elastic sheet is arranged inside the fixed chamber;
- and
- extended holes are arranged on both sides of the base, and the elastic sheet is fixedly provided with a boss that movably passes through the extended holes and is partially exposed to the outside;
- wherein the controller is pressed to radially retract the boss until the boss is snapped into the recessed groove, thereby completing installation, while the elastic sheet releases a resilience force after the boss is snapped into the recessed groove, driving the boss to continuously press against a side wall of the recessed groove, forming a self-locking fixation.
