Specifically, as shown in fig. 1, a cable is wound around the winding roll 100 and passes through the main support rod 200, and is mounted on the rotating bracket 300, an end of the rotating bracket 300 away from the main support rod 200 is an outlet of the cable, and the rotating bracket 300 is rotatably connected to the main support rod 200 to ensure that the outlet can rotate relative to the main support rod 200, that is, the cable exiting from the outlet can rotate relative to the main support rod 200. When the electric excavator gets electricity to the outside, one end of the cable is connected with an excavator power system, and the other end of the cable penetrates through the wire outlet to be connected with a power grid power distribution cabinet, so that the power system is communicated with a power supply, the transmission of the electric power is realized, and the excavator can normally work. When the excavator does a rotation action, the relative position of the excavator and the power distribution cabinet changes, the main support rod 200 is driven to move, the rotating bracket 300 which is rotatably connected with the main support rod 200 rotates around the axis of the main support rod 200, and the wire outlet rotates synchronously along with the rotating bracket 300 relative to the main support rod 200, so that the relative angle between the cable at the wire outlet and the power distribution cabinet is ensured to be constant, and the phenomenon that the cable is abraded to influence the work of the excavator is avoided.
In an alternative embodiment of the present invention, the main support rod 200 is rotatably connected to the main body, the fixing bracket 400 is rotatably connected to a position of the main body close to the main support rod 200, and when the main support rod 200 is rotated to the vertical position, the free end of the fixing bracket 400 is detachably connected to the main support rod 200, so that the fixing bracket 400 supports and fixes the main support rod 200.
In this embodiment, as shown in fig. 1, one end of the main support rod 200 is rotatably connected to the body, the other end is rotatably connected to the rotating bracket 300, one end of the fixed bracket 400 is rotatably connected to the body, the other end is detachably connected to the erected main support rod 200, and whether the fixed bracket 400 is connected to the main support rod 200 depends on the power-taking mode of the electric excavator. Specifically, when the excavator uses an external power supply, the main support rod 200 is manually erected, the fixing support 400 is erected and connected with the rod body of the main support rod 200 to support and fix the main support rod 200, at the moment, the cable is released by the rotatable winding roll 100 and penetrates through the main support rod 200 to be connected to a power distribution cabinet of a power grid, and external electricity taking is completed; when the excavator works by using a self-contained battery, the main support rod 200 and the fixed support 400 can be detached without using an automatic cable winding and unwinding device and can be put down, so that the hiding effect is achieved, and the overall appearance of the excavator is beautified.

In this embodiment, as shown in fig. 1, the main support bar 200 and the fixing bracket 400 are located in the same plane, which ensures the stability of the fixing bracket 400 to the main support bar 200. The main support rod 200 and the fixing bracket 400 can rotate leftwards or rightwards, and the forward or backward movement is limited due to the connection mode between the main support rod and the body, so that the main support rod and the fixing bracket have the movement trends in the same direction. In addition, the rotation plane of the main support bar 200 and the rotation plane of the fixing bracket 400 may not be in the same plane, that is, the rotation planes of the two intersect, in this case, the moving tendencies of the two are not the same, and when the two are connected, the direction of the force applied to each other and the direction of the moving tendency thereof have an angle other than 180 °, so that the connection between the two is not as stable as the former. It should be noted, however, that the main support bar 200 is connected to the fixing bracket 400 in such a case to satisfy the operation requirement of the automatic cable retracting device.
In an alternative embodiment of the present embodiment, the fixing bracket 400 is connected to the main support rod 200 by a fixing pin 500.

Specifically, the cable is wound or unwound through the pulley 600, when the cable is externally connected with a power distribution cabinet of a power grid, an operator operates the winding roll 100 to rotate to release the cable, the cable approaches to the power distribution cabinet of the power grid from the wire outlet through the pulley 600, when the cable is wound, the cable is wound from the wire outlet to the winding roll 100 through the pulley 600, in the winding and unwinding process, the pulley 600 not only prevents the cable from being abraded, but also changes the friction of the cable at the wire outlet into sliding friction, and the tensile force applied to the cable when the cable is wound or unwound is reduced. The provision of the pulley 600 saves manpower when the rotation of the winding roll 100 is in the manual mode, and the provision of the pulley 600 reduces power consumption when the rotation of the winding roll 100 is in the automatic mode.
