DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0021] Embodiment 1, by Figure 1-Figure 4The utility model includes a manual unlocking button 1, an angle servo driver 3, a wire bogie 6 and a door lock seat 9. An adjusting wheel 4 is installed on the output shaft of the angle servo driver 3. A plurality of adjusting holes 41 are provided on the adjusting wheel 4. The manual unlocking button 1 is connected to the adjusting hole 41 through a pull rope 2. One end of the adjusting hole 41 is connected to a wire rope 7.
