[0002] As we all know, the door is a device that can be opened and closed at the entrance and exit. There are various doors installed in offices, schools, factories, residential buildings and other buildings. Auxiliary devices that cause damage to door pages and supporting structures are widely used in schools, factories, laboratories, warehouses, residences and other fields; existing suction cup door devices include fixed plates, fixed rods and suction cups, fixed rods The left end and the right end of the door are respectively connected with the suction cup and the fixed connection; when the existing suction cup door device is in use, the fixed plate is fixed on the wall facing the door leaf when it is opened, and the door leaf is sucked by the suction cup to realize the fixing of the door leaf; During the use of the suction cup card door device, it was found that when the door is opened with a large force, the suction cup and the door leaf will be tightly attached to each other. It takes a lot of force to make the door leaf detach from the suction cup, which is inconvenient to use and the pulling force is too high. If it is too large, it is easy to cause damage to the door leaf and suction cup
