So you can lift by hand, in this case, you need to bend your back, which is inconvenient, and there is a problem that you need to wipe the foreign matter on your hand.

Second, when the door stopper folded close to the door is rotated downward, the door stopper is rotated by the force of pressing the ground rubber plate to the sole. As the gap is generated, there is a problem that the function of the door stopper, that is, the fixing force to the ground is not exerted.

Third, the ground rubber plate is in surface contact with the ground to maintain a strong fixing force, but the fixing force is so strong that the door should be pushed differently if intended, but when it is pulled or pushed outdoors, the ground rubber plate may be loosened due to loosening and repeated use of the door. Due to the wear of the surface contact force is deteriorated due to the friction force is reduced causes a problem that results in the fixing force is lowered.

Therefore, the present invention has been made in view of the above problems, the object of which is to facilitate the folding (folding) of the door stopper by the string pull method by the pedal to improve the operation convenience of the user, the rolling roller is prevented from rolling The present invention provides a door opening fixing stopper device which can prevent the reduction of the fixing force and facilitate the folding by the line contact method with the ground.
