The screw rod section includes a smooth section and a threaded section. The threaded section is threadedly connected with a locking nut 18. The number of locking nuts 18 is two and they are stacked in close contact. Through the structural method of stacking two locking nuts 18, the locking nuts 18 can be locked to avoid loosening naturally due to vibration and rotation.

[0024] Two symmetrically distributed first guide columns 9 are arranged on both sides of the first adjusting bolt 10, and the first guide columns 9 are connected to the slide plate 7 by bolts. A first guide sleeve 15 is slidably arranged on the outer side of the first guide column 9. The two first guide sleeves 15 are connected to a connecting plate 14, and a first mounting frame 13 is connected to the connecting plate 14. A light hole is opened on the connecting plate 14, and the inner side of the light hole passes through the first adjusting bolt 10.

The external socket 2, the end contour of the first mounting bracket 13, and the end contour of the cover plate 23 have the same shape. When the right end of the sliding plate 7 contacts the limiting block 8 located at the right end, the positions of the first mounting bracket 13 and the external socket 2 are relative. When the left end of the sliding plate 7 contacts the limiting block 8 located at the left end, the positions of the cover plate 23 and the external socket 2 are relative. Under normal conditions, the cover plate 23 is arranged inside the external socket 2, which can play a role in closing. It can not only maintain the integrity of the appearance of the swing platform side beam 1 but also protect the charging socket from external interference. When charging is required, use a wrench to turn the second adjusting bolt 20, so that the cover plate 23 slides inward along the second guide post 19 and completely disengages from the external socket. Manually control the cover plate 23 to slide to the right, so that the first mounting bracket 13 is aligned with the external frame. Then use a wrench to turn the first adjusting bolt 10, so that the connecting plate 14 slides outward along the first guide post 9 under the drive of the first adjusting bolt 10 and the locking nut 18, insert the end of the first mounting bracket 13 into the external socket 2 and tighten it, and then charging can be carried out.

[0028] The utility model sets the charging socket inside the side beam of the excavator's slewing platform, near the side wall. Through a structure that can switch positions, the socket is made visible during use, and when not in use, the cover plate 23 is used to cover and protect the socket, achieving the function of facilitating charging by setting it inside the swing platform side beam 1 and improving the safety factor by switching the usage state.
