In specific implementation, the cooperation between the protrusion and the limit portion can be a snap connection or a magnetic positioning.

[0034] In the above technical solution, a protrusion is provided on the rocker arm 2, and a limiting portion is provided on the limiting seat 3. The protrusion and the limiting portion cooperate with each other to locate the position of the rocker arm 2. The electronic hand throttle structure is changed, and positioning points are added to fix the throttle size. This is suitable for fixing the throttle position under specific working conditions, which is convenient and quick, and greatly saves the user's time and operating experience.

[0035] In a specific feasible implementation, the raised portion includes an elastic member 4 and a clamping member 5, the limiting portion is a groove 6, one end of the elastic member 4 is connected to the rocker arm 2, and the other end is connected to the clamping member 5, and the elastic member 4 is used to press the clamping member 5 into the groove 6; the number of the grooves 6 is multiple (two or more), such as two, three, and other different numbers. In this embodiment, three are taken as an example for explanation. The clamping member 5 and the groove 6 are clamped to locate the position of the rocker arm 2. The elastic member 4 is a compression spring. The clamping member 5 is a roller.
