[0002] The low-voltage drawer cabinet is similar to a low-voltage power distribution cabinet, which includes control equipment, power input, circuit breakers and other components. The device can be set with different connection methods according to specific system requirements to meet the needs of power transmission and control. The outgoing line loop refers to the circuit part of the electrical equipment or circuit used to connect the power output end to the target device or system. The outgoing line loop is a very important part of the circuit design. When designing, it is necessary to consider factors such as power capacity, line load, safety and wiring method to ensure that the electric energy can be stably and safely output to the target device. The outgoing line loop often uses a wiring board, which can reasonably distribute the arrangement of the lines and facilitate daily maintenance.

[0032] The guide block 403 and the fixed block 404 form an integral structure, and the rotating block 408 is rotatably connected with the rotating groove 405 through the rotating block 406. The rotating block 408 and the rotating block 406 are an integral structure. When the line of the drawer cabinet is routed, the line is moved to the top of the rotating block 408 and pressed downward. When the rotating block 408 is pressed, the rotating block 406 can be driven to move. When the rotating block 406 moves, it can rotate through the rotating groove 405. When the rotating block 406 rotates, the torsion spring 407 can be tightened. After the rotating block 408 is rotated to a certain position, the line can be pressed to the inside of the connecting block 401. At this time, the torsion spring 407 can be reset by its own torque. When the torsion spring 407 is reset, the rotating block 408 can be driven to reset.
