When one of the two intermediate gears is aligned with the notch, the other intermediate gear is also meshed with the lock head transmission gear so as to ensure that the lock head transmission gear and the transition gear are in a continuous transmission state.

The positioning push plate is characterized by further comprising a spring, and the spring can enable the positioning push plate to reset.

The lock head transmission gear is provided with a notch.

The spring bolt promotes the gear including locating the boss on the spring bolt promotes the gear main part, just the boss is the ellipse, and it includes circular arc part and linear part promptly, just linear part is locating surface B, and is equipped with the fixed orifices on the circular arc part respectively.

Two fixing columns are arranged on the transition gear.

The location push pedal includes location push pedal main part, and location push pedal main part inside is equipped with the fixed slot, is equipped with a fixed part in the location push pedal main part, and the other end is equipped with two butt portions, the fixed slot is the circular recess that one side was equipped with straight portion part, straight line part is locating surface A.

The boss can rotate in the fixing groove, and a positioning surface B of the boss can be abutted to the positioning surface A, so that positioning is carried out.

The upper cover of the driving assembly is covered under the driving assembly to form a shell, the lower cover of the driving assembly is provided with a positioning shaft, the gap bridge gear, the transition gear and the spring bolt push gear sleeve are arranged on the positioning shaft, and a bearing is arranged outside the positioning shaft of the spring bolt push gear.

The invention has the advantages that: the invention solves the problems of gear jumping and gear falling off in the opening or locking process.
