Preferably, a through hole 14 for the push rod 3 to protrude outwards is formed between the first housing 11 and the second housing 12, and an end of the push rod 3 protruding outwards in the initial position is flush with an opening of the through hole 14.
The transmission assembly 5 includes a central shaft 51 fixed on the base 1, a driving wheel 52 sleeved on the central shaft 51, a driven wheel 53, and at least one transmission wheel for connecting the driven wheel 53 and a push rod. The driving pulley 52 and the driven pulley 53 are disposed adjacent to each other in the axial direction of the center shaft 51. The driving wheel comprises a first driving wheel 541 meshed with the driven wheel 53 and a second driving wheel 542 connecting the first driving wheel 541 and the push rod 3, and a rack 31 meshed with the second driving wheel 542 is formed on one side of the push rod 3 facing the second driving wheel 542. The first driving wheel 541 and the second driving wheel 542 can be set with different transmission ratios according to actual door opening requirements. The first driving wheel 541 is correspondingly provided with a first pivot shaft 543, the second driving wheel 542 is correspondingly provided with a second pivot shaft 544, the first pivot shaft 543 and the second pivot shaft 544 are fixed on the base 1, and the first pivot shaft 543 and the second pivot shaft 544 are both parallel to the central shaft 51.
