A base gear 7 located in the housing 1 is fixedly arranged on the transmission sleeve 5, a fixed gear 8 coaxial with the transmission shaft 2 is fixedly arranged in the housing 1, and an upper end of the transmission shaft 2 is sleeved with the fixed gear 8 and is only allowed to rotate around its axis. Three connecting shafts 9 which are distributed in a circular array around the transmission shaft 2 are perpendicularly and fixedly arranged on the base gear 7, each connecting shaft 9 is sleeved with a second gear 10 and a third gear 11 which are able to rotate around a central line of the connecting shaft 9, the second gear 10 and the third gear 11 are fixedly connected, the second gear 10 meshes with the first gear 3, and the third gear 11 meshes with the fixed gear 8. The diameter of the second gear 10 is greater than the diameter of the third gear 11, the diameter of the first gear 3 is less than the diameter of the fixed gear 8, and the diameter of the fixed gear 8 is greater than the diameter of the third gear 11. A connecting ring 12 configured as a circular structure is arranged above the base gear 7 and disposed around the fixed gear 8, and upper ends of the connecting shafts 9 are fixedly connected to the connecting ring 12.

[0026] As shown in FIG. 3, a power mechanism for driving the base gear 7 to rotate is fixedly arranged on the housing 1. The power mechanism includes a shell 13 fixed to a side face of the housing 1, a motor 14 and a reducer 15 are fixedly arranged in the shell 13, a rotating shaft of the motor 14 is connected to an input end of the reducer 15, and a moving gear 16 meshing with the base gear 7 is arranged at an output end of the reducer 15.

[0027] As shown in FIG. 2 and FIG. 4, a clamping ring 22 configured as a circular structure is fixedly arranged on each of two sides of the housing 1, teeth 23 are distributed on an inner side of the clamping ring 22, a fixing ring 24 which is fixed to the housing 1 and configured as a circular structure is arranged in the clamping ring 22, and the fixing ring 24 is coaxial with the clamping ring 22. Two parallel connecting plates 25 are fixedly arranged on the handle 21, a retaining ring 26 configured as a circular structure is fixedly arranged on an inner side of each connecting plate 25, the outer diameter of the retaining ring 26 is equal to the inner diameter of the fixing ring 24, the two connecting plates 25 are arranged on two sides of the housing 1 respectively, the two retaining rings 26 on the two connecting plates 25 are sleeved with the two fixing rings 24 respectively, and the handle 21 is rotatably connected to the housing 1 by means of the retaining rings 26 and the fixing rings 24.

[0028] As shown in FIG. 2, FIG. 3 and FIG. 5, two connecting pieces 27 are slidably connected into the handle 21 and are in one-to-one correspondence with the two clamping rings 22, the two connecting pieces 27 are only allowed to move in a radial direction of the corresponding clamping rings 22, a clamping piece 28 which is located on the inner side of the corresponding clamping ring 22 and is able to mesh with the teeth on the corresponding clamping ring 22 is fixedly arranged at one end of each connecting piece 27, a button 29 is fixedly arranged between outer ends of the two connecting pieces 27, a spring 30 for driving the clamping pieces 28 to move towards the teeth 23 is arranged between the handle 21 and the button 29. A through groove 31 is formed in the handle 21, and the button 29 is arranged in the through groove 31.

[0029] When the bidirectional cleaning machine provided by the invention is used for cleaning, the motor 14 of the power mechanism drives the reducer 15 to operate, the reducer 15 then drives the moving gear 16 to rotate, the moving gear 16 drives the base gear 7 to rotate, the base gear 7 drives the outer cleaning ring 6 to rotate by means of the transmission sleeve 5, and at the same time, the base gear 7 drives the connecting shafts 9 to rotate synchronously; because the fixed gear 8 is fixed in the housing 1 and the third gear 11 on the connecting shaft 9 meshes with the fixed gear 8, the third gear 11 rotates around the fixed gear 8 when the connecting shafts 9 rotate with the base gear 7, at the same time, the third gear 11 drives the second gear 10 to rotate synchronously, the second gear 10 drives the first gear to rotate to drive the transmission shaft 2 to rotate in a direction opposite to the rotation direction of the transmission sleeve 5, so the rotation direction of the inner cleaning disk 4 driven by the transmission shaft 2 is opposite to the rotation direction of the outer cleaning ring 6. In this way, bidirectional rotation is realized to fulfill a better cleaning effect. When the relative angle between the handle 21 and the cleaning mechanism needs to be adjusted, the button 29 is pressed, then the button 29 drives the connecting piece 27 to rotate synchronously, the connecting pieces 17 drive the clamping pieces 28 to be separated from the teeth, at the same time, the handle 21 and the cleaning mechanism are unlocked, the handle 21 can be rotated to adjust the relative angle between the handle 21 and the cleaning mechanism. After the relative angle between the handle 21 and the cleaning mechanism is adjusted, the button 29 is released and returns to the initial position under the action of the spring 30 to drive the connecting pieces 27 to move towards one side of the button 29, and the clamping pieces 28 mesh with the clamping teeth 23, such that operation is easy.
