[0012] In order to make the above features and advantages of the present invention more obvious and understandable, embodiments are given below with reference to the accompanying drawings for detailed description as follows.

[0013] like Figure 1 and Figure 2 As shown, this embodiment provides a special tightening device of electric drive, including a support seat 1, a driving cylinder 2, a connecting rod 3, a supporting rod 4 and a tightening wrench 5. The driving cylinder 2 is mounted on the supporting seat 1, and the output end of the driving cylinder 2 is protruded toward the bottom of the supporting seat 1. The supporting rod 4 is mounted below the supporting seat 1. The tightening wrench 5 is rotatably mounted at the lower end of the supporting rod 4. One end of the connecting rod 3 is connected to the output end of the driving cylinder 2, and the other end of the connecting rod 3 is rotatably connected to the tightening wrench 5. When tightening is to be performed, the tightening wrench 5 is vertically arranged to extend into the electric drive housing, and at the same time, the driving cylinder 2 slowly drives the connecting rod 3 to make the tightening wrench 5 horizontally arranged, so that the tightening wrench 5 is stably placed in the electric drive housing, so as to achieve auxiliary extension, facilitate operation and increase efficiency.

[0014] Further, the tightening wrench 5 is a right-angle wrench, the support rod 4 is hollow, and a driving rod 6 connected to the right-angle wrench is provided in the support rod 4 for lifting and lowering, and a lifting cylinder 7 for driving the driving rod 6 to move up and down is provided on the support seat 1. Specifically, the tightening wrench 5 includes a mounting shell, a transmission rod, a tightening head and a transmission head, the mounting shell is rotatably mounted on the lower end of the support rod 4, the transmission rod is rotatably placed in the mounting shell, the tightening head and the transmission head are rotatably placed at the two ends of the mounting shell, and the transmission head is located below the support rod 4, and the two ends of the transmission rod are respectively provided with driving bevel gears connected to the tightening head and the transmission head, and the tightening head and the transmission head are coaxially provided with a transmission bevel gear meshing with the driving bevel gear, and the transmission head is provided with a connecting four-corner groove, and the bottom end of the driving rod 6 is provided with a four-corner protrusion adapted to the four-corner groove. When the tightening wrench 5 swings into place, the driving rod 6 is driven to descend by the lifting cylinder 7, so that the driving rod 6 is connected to the tightening wrench 5 for driving tightening.
