The rope winding wheel 3 comprises a main driving disc 31 and a rope winding disc which are coaxially fixed, in the embodiment, the rope winding disc comprises three wheel discs 32 which are arranged at an upper interval and a lower interval, and the main driving disc 31 and the three wheel discs 32 can synchronously rotate. The bottom of the uppermost disk 32 has a first spacer 321 having a disk shape, and the bottom of the middle disk 32 has a second spacer 322 having a disk shape, and the first spacer 321, the second spacer 322, and the disk 32 are coaxially arranged. A first wheel groove 323 is thus formed between the uppermost wheel disc 32 and the middle wheel disc 32, a second wheel groove 324 is formed between the middle wheel disc 32 and the lowermost wheel disc 32, and the first wheel groove 323 and the second wheel groove 324 are arranged parallel to each other and spaced apart in the axial direction. The washing line may be received in the first wheel groove 323 (outer periphery of the first spacer 321) and the second wheel groove 324 (outer periphery of the second spacer 322). And the outer diameter of the outermost turn of the coiled line is not greater than the outer diameter of the wheel disc 32. The main transmission disc 31 is positioned below the wheel disc 32 and is used for being in transmission connection with the motor 2. The three wheel discs 32 and the main drive disc 31 are coaxially fixed by means of two jackbolt pins 34, ensuring synchronous rotation.

The motor 2 is arranged adjacent to the main housing 1, an output shaft 21 of the motor 2 extends into the main housing 1, a worm 22 is arranged on the output shaft 21 of the motor 2, the worm 22 is meshed with a main transmission disc 31 (the worm 22 extends in the tangential direction of the main transmission disc 31), and the main transmission disc 31 is of a worm gear structure. Thus, when the motor 2 is operated, the main drive disc 31 can be rotated by the worm 22. The worm and gear structure has the effect of speed reduction. In addition, further, the main transmission disc 31 and the wheel disc are coaxially fixed, and the outer diameter of the main transmission disc 31 is larger than that of the wheel disc, so that the tangential linear velocity of the wheel disc is smaller than that of the main transmission disc 31 under the condition that the angular velocities of the main transmission disc and the wheel disc are the same, and therefore the main transmission disc 31 plays a role in further transmission and speed reduction. Because main drive dish 31 and each rim plate (race) coaxial arrangement for the radial dimension of main drive dish 31 can be as big as possible relative race to increase the reduction ratio, under the unchangeable condition of motor 2's power, the output torque of motor 2 has showing the increase after passing through rope sheave 3 compared with prior art, consequently can improve the load capacity of load.

Thus, the prongs 45 form a separate portion from the tray body 43, and the prongs 45 are adapted to be secured to an external mounting base. The convex foot 45 uses the elasticity of metal, so that the connection part with the outside forms non-rigid connection but elastic connection transition, thereby consuming part of vibration energy and weakening the noise generated by vibration. Of course, the tray 43 is not necessarily a disk shape, and may have an irregular shape.

The outboard end of each leg 45 remote from the tray 43 forms a C-shaped clip opening 46 recessed into the tray 43 to facilitate installation.
