[0011] The hanging point fixture 5 is a trapezoidal structure as a whole, with a through hole in the middle and a stepped groove at the bottom.

[0012] The lead screw 3 is a ball screw.

[0013] The lower part of the lead screw 3 is provided with a hook structure.

[0014] The lower part of the hanging point fixture 5 can cooperate with a “┬”-shaped hanging point slot, a “┐”-shaped hanging point slot and a “┴”-shaped hanging point slot.

[0015] The load-bearing hanging point is used to fix the chain-type hanging hook or screw; the middle hole can be connected and fixed with the upper through hole of the 5-hanging point fixture by bolts; the screw is used for ground wire lifting; the hanging point fixture provides a stable fixing and support point for the hooking device.

[0016] Advantages of the present invention:
