During the operation of the actuator mechanism 500 driving the rotary base 300 and the first connection end 410 of the rotary arm 400, the rotary arm 400 makes a curved motion with the second end a620 of the first link 600 as a fulcrum, so that the scissor door swings upward or downward.

The structure and the installation of the rotating arm 400 are optimized integrally aiming at the stress problem of the original hinge, and the service life of the rotating arm 400 can be greatly prolonged through the optimization.
