[0022] Among them, the second clamping block 9 is clamped inside the first clamping block 8. Then, both sides of the second clamping block 9 can correspond to the two groups of positioning blocks 11, which is convenient for the second mounting hole 13 and the third mounting hole 15 to correspond. The arc chamfers 12 provided on the opposite sides of the positioning blocks 11 facilitate clamping the second clamping block 9 between the two groups of positioning blocks 11. Then, the fixing screw can be installed between the second mounting hole 13 and the third mounting hole 15, thus facilitating the installation and fixation of the positioning block 11 and the second mounting plate 14.

[0023] Please refer to Figure 1 and Figure 2 , the connecting curved arm 4 includes a fixed sleeve 16, a driving arm 17, a first connecting arm 18 and a second connecting arm 21. The output end of the rotary cylinder 3 is fixedly installed with a fixed sleeve 16. The bottom of the fixed sleeve 16 is fixedly connected with a driving arm 17. One end of the driving arm 17 is rotatably connected with a first connecting arm 18. A first threaded rod 19 is fixedly connected to one side of the first connecting arm 18.

[0024] Among them, rotate the threaded sleeve 23 to adjust the position between the first threaded rod 19 and the second threaded rod 22. Then, the reinforcement mechanism 5 can be installed at the corresponding position of the door panel. When the opening and closing door needs to be opened and closed later, start the rotary cylinder 3 to operate. The rotary cylinder 3 drives the driving arm 17 to rotate. Then, it can push the first connecting arm 18 and the second connecting arm 21 to push the reinforcement mechanism 5 to move. Then, the automatic opening and closing of the opening and closing door can be completed.

[0025] Please refer to Figure 2 and Figure 3 , the reinforcement mechanism 5 includes a hinge seat 20, a locking bolt 24, a reinforcement piece 25 and a locking nut 26. One end of the second connecting arm 21 away from the second threaded rod 22 is hinged with a hinge seat 20. Two groups of locking bolts 24 are arranged on the hinge seat 20. A reinforcement piece 25 is arranged on the outer surfaces of the two groups of locking bolts 24. A locking nut 26 is threadedly connected to the outer surface of the locking bolt 24 on one side of the reinforcement piece 25.

[0026] Among them, when the reinforcement mechanism 5 is installed, drill two through holes through which the locking bolts 24 can pass. Then, pass the locking bolts 24 through the through holes. One side of the hinge seat 20 fits against the front of the door panel. Then, sleeved the reinforcement piece 25 on the outer surface of the locking bolt 24, and make the reinforcement piece 25 fit against the back of the door panel. Then, use the locking nut 26 to fix the reinforcement piece 25, and the installation of the reinforcement mechanism 5 can be completed.

[0027] During use, first, the set fixing mechanism 1 can be fixedly installed on the door frame. Then, the clamping mechanism 2 and the rotary cylinder 3 can be installed on the surface of the fixing mechanism 1. This installation method facilitates the quick removal of the rotary cylinder 3, the connecting crank arm 4, etc. for maintenance. Then, install the reinforcement mechanism 5 on the opening and closing door. The setting of the reinforcement mechanism 5 can increase the contact area between one end of the connecting crank arm 4 and the opening and closing door, preventing damage to the rotary cylinder 3 and the connecting crank arm 4 when pushing the opening and closing door to open and close. Pass the fixing screw through the first mounting hole 7, and then the first mounting plate 6 can be installed and fixed. Clamp the second clamping block 9 inside the first clamping block 8. Then, both sides of the second clamping block 9 can correspond to the two positioning blocks 11, facilitating the alignment of the second mounting hole 13 and the third mounting hole 15. The arc chamfer 12 provided on the opposite side of the positioning block 11 facilitates the clamping of the second clamping block 9 between the two positioning blocks 11. Then, it can be installed with fixing screws between the second mounting hole 13 and the third mounting hole 15, thus facilitating the installation and fixing of the positioning block 11 and the second mounting plate 14. Then, rotate the threaded sleeve 23 to adjust the position between the first threaded rod 19 and the second threaded rod 22. Then, the reinforcement mechanism 5 can be installed at the corresponding position of the door panel. When the opening and closing door needs to be opened and closed, start the rotary cylinder 3 to operate. The rotary cylinder 3 drives the driving arm 17 to rotate, and then can push the first connecting arm 18 and the second connecting arm 21 to push the reinforcement mechanism 5 to move, and then the automatic opening and closing of the opening and closing door can be completed. Among them, when the reinforcement mechanism 5 is installed, drill two through holes through which the locking bolts 24 can pass. Then, pass the locking bolts 24 through the through holes. One side of the hinge seat 20 fits against the front of the door panel. Then, sleeved the reinforcement piece 25 on the outer surface of the locking bolt 24, and make the reinforcement piece 25 fit against the back of the door panel. Then, use the locking nut 26 to fix the reinforcement piece 25, and the installation of the reinforcement mechanism 5 can be completed.
