[0020] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0021] A specific embodiment of the motor assembly of the present invention is as follows Figure 2As shown, the motor assembly in the present invention mainly includes a motor 1, a wheel 2 and a rope 4 assembled on the motor 1. The wheel 2 is provided with a center hole 6 that cooperates with the motor shaft 8. The wheel 2 is also provided with a groove 7 for accommodating the rope and a top screw 3 that tightens the motor shaft 8 to make the wheel 2 and the motor shaft 8 rotate synchronously.

[0022] like Figure 3 As shown, in order to conveniently and quickly fix the rope 4 on the rotating wheel 2, a penetration hole 5 is provided on the groove 7 of the rotating wheel 2 in this embodiment, and the penetration hole 5 is connected with the center hole 6 of the rotating wheel 2, and the hole opening of the penetration hole 5 and the center hole 6 are arranged along the axis of the center hole, and the rope 4 passes through the penetration hole 5 and passes out through the center hole 6. In order to facilitate the processing of the penetration hole 5, the axis of the penetration hole 5 in this embodiment is arranged parallel to the top screw 3.

[0023] like Figure 1 and Figure 2 As shown, in order to prevent the motor shaft 8 and the top screw 3 from slipping after the top screw 3 is pressed, a pressing section is provided on the motor shaft 8, and the cross section of the pressing section is D-shaped. The top screw 3 presses the rope 4 against the plane of the pressing section to fix it, and the motor shaft 8 cooperates with the rotating wheel 2 with the plane on the pressing section facing the direction of the through hole 5, and the rotating wheel 2, the motor shaft 8 and the rope 4 are pressed and fixed by the top screw 3. In other embodiments, the axis of the penetration hole can also be set in other directions, forming a certain angle with the axis of the top screw. In other embodiments, the top screw can be directly pressed against the rope and the motor shaft without setting a pressing section, or the shape of the pressing section can be other shapes, such as setting a groove on the motor shaft, and the top screw is pressed against the rope in the groove.

[0024] In order to allow the rope 4 to be wound in an orderly manner, the groove 7 in this embodiment is a V-shaped groove, and the penetration hole 5 is arranged at the bottom of the V-shaped groove, so that when the rope 4 is wound, the rope 4 can be wound in an orderly manner and the rope 4 is not easily worn. In other embodiments, the groove 7 can also be a flat-bottomed U-shaped groove, and the penetration hole is arranged at the bottom of the groove 7.

[0025] Compared with the conventional wheels, the wheel 2 of the present invention only needs to machine the insertion hole 5 connected with the center hole 6 on the groove 7. When fixing the rope 4, the rope 4 only needs to be inserted through the insertion hole 5, and then the wheel 2 equipped with the rope 4 is matched with the motor shaft 8 in the direction of the top screw facing the plane of the motor shaft 8, and finally the rope 4, the motor shaft 8 and the wheel 2 are simultaneously tightened by the top screw 3 to complete the fixing of the rope 4. After the rope 4 is fixed, it can be rotated by the motor to pull other objects.

[0026] The specific embodiment of the rotating wheel of the present invention has the same structure as the rotating wheel in the above-mentioned motor assembly, and will not be described in detail.
