New breaker with automatic opening and closing function

The invention relates to the field of low voltage electrical apparatus, in particular to a novel breaker with automatic opening and closing function. The novel breaker with automatic opening and closing function comprises: a breaker body and an operating mechanism for use with the breaker body; a trip button, wherein the trip button is pressed to open a main body of the breaker; a locking mechanism; a rotary locking mechanism, wherein the locking mechanism drives the main body of the breaker to be opened by the trip button, and the locking mechanism locks the trip button, and the locking mechanism enables the operating mechanism to be powered off. According to the new breaker with automatic opening and closing function, the main body of the breaker is stable and reliable in an opening state. 本发明涉及低压电器领域，具体涉及种具有自动分合闸功能的新型断路器，其包括断路器主体以及与断路器主体配合使用的操作机构；还包括跳闸按钮，按压跳闸按钮能使断路器主体分闸；还包括锁定机构，旋转锁定机构，锁定机构通过跳闸按钮驱动断路器主体分闸，且锁定机构锁定跳闸按钮，同时锁定机构使操作机构断电；本发明可使断路器主体稳定可靠的处于分闸状态。
