They are used together with the embodiments of the present invention to explain the present invention and do not constitute a limitation to the present invention. DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] like Figure 1-3 As shown, the utility model proposes a multi-degree-of-freedom rotating electric hook, including an upper box body 1, a rotary drive component 2, a lower box body 3 and a mountain-shaped hook head 4, the rotary drive component 2 is installed on the upper box body 1 and is arranged through the upper box body 1, the lower box body 3 is fixedly arranged on the rotary drive component 2, the mountain-shaped hook head 4 is pin-connected to the lower box body 3, the rotary drive component 2 includes a rotary bearing 10, a reduction motor 11 and a pinion 12, the rotary bearing 10 is rotatably installed at the bottom of the upper box body 1, the reduction motor 11 is fixedly arranged on the upper side of the upper box body 1, the pinion 12 is fixedly installed on the output shaft of the reduction motor 11 and is meshed with the rotary bearing 10, in order to improve stability, a pinion pressure plate 14 is provided on the pinion 12.

[0021] like Figure 1-3 As shown, in order to improve the connection strength, connect and realize multi-angle lifting, the lower box body 3 includes a lower bracket 8 and a cross connector 9, the lower bracket 8 is fixed on the slewing bearing 10, the cross connector 9 is pin-connected to the lower bracket 8, and the mountain-shaped hook head 4 is pin-connected to the cross connector 9.
