Problems solved by technology

[0003] During the construction process, the operator may constantly pull the power cord to reach different work areas due to the needs of the work, which often causes the power cord and the socket device to loosen, causing unexpected interruption to the work
This kind of interruption will not only reduce the construction efficiency and bring inconvenience to the operator, but also in some more important work occasions, this unexpected power interruption will cause safety accidents

Description

technical field [0001] The present application relates to the field of construction machinery, in particular to a power cord connection locking device for construction machinery with return springs. Background technique [0002] In the process of building construction, some movable machinery is usually used, such as some grinders, eye drills and some movable power tools. These machines require a larger operating range or radius and typically have longer power cords. [0003] During the construction process, the operator may constantly pull the power cord to reach different work areas due to the needs of the work, which often causes the power cord and the socket device to loosen, causing unexpected interruption to the work. This interruption will not only reduce the construction efficiency and bring inconvenience to the operator, but also in some more important work occasions, this unexpected power interruption will cause safety accidents. Contents of the invention [000...
