Description

Easily-pulled socket structure capable of saving pressing force and resisting ignition Technical Field The invention relates to the technical field of sockets, in particular to a push-down force-saving and spark-resistant easily-pulled socket structure. Background In actual use, in order to make the pin of the plug not easy to fall off after being inserted into the socket, the clamping elastic pieces inside the socket have certain clamping force, so that quite a pulling force is required during pulling out, especially the row is inserted, the pulling-out action can be completed by two hands, and the wall is very easy to fall off from the wall due to long-term stress after being used for a long time, so that the wall is very inconvenient and unsafe to use. The design concept of the easy-to-pull socket solves the defect of the traditional socket. The conventional easy-to-pull socket adopts the following modes that firstly, a push-to-pull push switch is added (such as a switch ejection plug and a switch ejection clamping elastic sheet are disclosed in patent numbers WO2001009984A1 and CN 106803628A), the structure is simple, but when the socket is pulled, hands need to move at two places of the push switch and the plug, the action is relatively fussy, the structure is huge, the product is not easy to miniaturize, secondly, a clamping and releasing mode is controlled by adopting an electromagnet or an electromagnetic liquid circuit (such as the technical scheme disclosed in patent number CN108462007B, CN 109586106A), the push-to-pull push switch cannot be widely popularized and used due to the fact that the high cost is relatively difficult to implement, and thirdly, the push-to-push switch is cyclically pressed by one hand (which means one-time push locking and two-time push releasing are performed, such as the technical scheme disclosed in patent number CN207559185U, CN 111129864A), but the structure is basically a simple spring direct ejection mode, the elastic force of the used ejection spring needs to be larger than the clamping force of the elastic sheet on the pins, for example, when the pin holding force is 5 kg of the pins is required, the ejection spring needs to be larger than 5 kg of holding force of the pins, and the force is more difficult to hold by the hands of a person to be more than the adult, namely, the push-to hold force is more difficult to be tested by the human body 10 kg of a person is more difficult to hold by the hands for an adult, and is more than the force to be tested by the human body. Meanwhile, the pin of the plug with load is easy to generate high-voltage ignition when being inserted into the socket, the traditional socket comprises the traditional socket, the adopted pin and the elastic sheet are in direct contact at the first time, the ignition point is overlapped with or very close to the contact point, oxides can be accumulated at the ignition point after multiple ignition, the contact surface is not flat any more, poor contact is caused, and the service life of the socket is very limited, especially in some use occasions requiring frequent plugging. Therefore, there is a need for an easy-to-pull socket structure that is resistant to ignition while saving pressing force, and solves the above-mentioned problems. Disclosure of Invention The invention aims to provide a push-down force-saving and spark-resistant easily-pulled socket structure, so as to solve the problems that the conventional socket is inconvenient to use and has extremely short service life due to spark. To achieve the above object, the present invention provides the following solutions: The invention provides a push-force-saving and spark-resistant easily-pulled socket structure which comprises a surface cover, a main spring, a clamping spring, a main spring, a second contact assembly, a connecting spring and a lock catch, wherein the surface cover is slidably arranged on a bottom cover, a circular push-locking function is realized by the main spring and the lock catch, the first contact and the clamping spring are respectively arranged at corresponding positions on the surface cover, the main spring, the second contact assembly, the connecting spring and the lock catch are respectively arranged at corresponding positions on the bottom cover, a containing cavity is arranged on the bottom cover, the positions of the containing cavity correspond to the longitudinal positions of the clamping spring, the connecting spring and a pin, a force arm AC formed by the force point A, the force point B and the pivot point C is longer than a force arm BC formed by the force point B and the pivot point C, meanwhile, the containing cavity is made of a plastic material with low friction coefficient, the first contact and the clamping spring are electrically connected, and the second contact assembly is electrically connected with the connecting spring, when the socket is in a release state, and the distance between the firs
