The existing door stopper has various forms and mainly adopts inclined struts, suckers, wedges and other structures, and the door stopper is generally installed between a door body and the ground or between the door body and a wall surface when in use. For example, CN203113969U discloses a sucker type door stopper, which can set the end of the door stopper to a sucker type structure, and connect a door panel and a wall surface through a sucker. However, when the normal opening and closing functions of the door are to be restored, the common door stopper needs to be detached, and the door stopper is troublesome to use under the condition of frequent door stopper requirements. On the other hand, if the door stopper is mounted on the door body or the ground by means of bolts, glue, or the like, it is difficult to apply different doors to the same door stopper, and the flexibility of use thereof is lowered.
