1. according to the scheme, the driving mechanism is pushed to open or close the first door leaf, the second traction rod, the triangular connecting piece and the transmission structure of the first traction rod are adopted to close the second door leaf to the first door leaf, so that the first door leaf and the second door leaf are driven respectively, the driving of the second door leaf is actually dependent on the driving of the first door leaf, and therefore the first door leaf and the second door leaf are driven respectively by two different mechanisms, the transmission stability is effectively improved, the technical problems that the swinging is easily caused when the door leaf hinge structure is opened and the service life of the door leaf hinge structure is shortened are effectively solved.

2. Present pedestal and first door leaf often are limited to the environment when the installation, and can not realize effectual parallel or perpendicular, this is the convenient regulation when the regulation setting of very first articulated seat can effectively realize the installation, wherein, the setting through the mounting hole more than three and the mounting hole more than two, can form multiple installation cooperation pattern, the through-hole setting in this scheme sets up to nine, the mounting hole sets up to three, and the mounting hole sets up to the bar hole, can realize the cooperation of wearing to establish of many patterns like this, thereby reach the purpose of effective regulation, reach convenient installation under the arbitrary installation environment.

3. The second hinged seat is the same as the first hinged seat in structure, so that the mutual interference influence can be effectively avoided when the two hinged seats are installed, and the installation under any installation environment is facilitated.

4. The first and second draw bars may be straight bars, which requires precision in the machining of each folding door and is relatively inconvenient to install. When the turnbuckle is used for implementation, the length of the turnbuckle can be effectively adjusted, so that the turnbuckle can be conveniently installed in any installation environment. When the air spring is used for realizing the purpose, the purpose is similar to that of a turnbuckle, and the buffer in the process of opening and closing the door can be increased.

5. The pushing driving mechanism and the second traction rod are respectively arranged at the upper end and the lower end of the first door leaf, and the arrangement aims to realize effective balance and improve the overall stability.
