Problems solved by technology

[0004] However, the lock body whose opening and closing is controlled by a key must be carried with you in use, and it is easy to forget or lose it so that the opening and closing control cannot be performed, causing inconvenience and trouble in use, which is one of the shortcomings of the existing door stopper structure. one

[0005] Furthermore, because in a modern society with developed industry and commerce, all vehicles such as automobiles and motorcycles, or the doors of homes, offices and other places need keys to control and switch, everyone has a lot of keys to carry in their existing lives. The structure controlled by the key will increase the carrying burden of consumers and reduce the acceptance of consumers, which is the second shortcoming of the existing door stopper structure.

[0006] Finally, if the key control structure is used, once the key is lost, the consumer will have to spend money to get a new key, which will further increase the unnecessary cost of the consumer, which is not in line with economic benefits, and is the third shortcoming of the existing door stopper structure.

[0007] Therefore, how to address the inconvenience and troubles of using the above-mentioned existing door stopper structure that cannot be used for opening and closing control due to forgetting and losing, and increase the burden on consumers to use and reduce the acceptance of consumers in use, and further increase consumers. Unnecessary expenses, disadvantages such as inconsistency in economic benefits and improvement inventions are the difficulties to be solved by the present invention
