Description

CROSS REFERENCE TO THE RELATED APPLICATIONS This application is the national phase entry of International Application No. PCT/CN2021/093759, filed on May 14, 2021, which is based upon and claims priority to Chinese Patent Application No. 202110231219.2, filed on Mar. 2, 2021, the entire contents of which are incorporated herein by reference. TECHNICAL FIELD The invention belongs to the technical field of cleaning machines, in particular to a bidirectional cleaning machine. BACKGROUND Floors, bottom plates, hulls and other positions need to be cleaned frequently by means of tools such as mops. Traditional mops have an unsatisfactory cleaning effect and need to be dragged back and forth frequently, which is labor-consuming. To save labor, automatic cleaning machines with a mop head capable of rotating automatically appear on the market. Compared with traditional mops, the automatic cleaning machines have a better cleaning effect and easier to use. However, the cleaning disk of existing cleaning machines can only rotate in one direction and has a moderate cleaning effect on some stubborn stains, thus failing to satisfy use requirements; in addition, the handle on existing cleaning machines is fixedly connected to the cleaning machines, and the angle between the handle and the cleaning machines cannot be adjusted, making the cleaning machines inconvenient to use. SUMMARY In view of the defects of unsatisfactory cleaning effect and inconvenience in cleaning of cleaning machines in the prior art, the invention provides a bidirectional cleaning machine. An inner cleaning disk and an outer cleaning ring of the bidirectional cleaning machine can rotate synchronously in opposite directions, such that the cleaning effect is better; and the angle between a handle and a cleaning mechanism can be adjusted according to personal requirements, such that the bidirectional cleaning machine is convenient to use. The objective of the invention is fulfilled through the following technical solution: a bidirectional cleaning machine includes a cleaning mechanism and a handle; the cleaning mechanism includes a housing, a transmission shaft only allowed to rotate around its axis is mounted in the housing, a first gear located in the housing is fixedly arranged on the transmission shaft, and an end of the transmission shaft stretches out of the housing and is fixedly connected to an inner cleaning disk; the transmission shaft is sleeved with a transmission sleeve which is only allowed to rotate around its axis, an end of the transmission sleeve stretches out of the housing and is perpendicularly and fixedly connected to an outer cleaning ring, and the outer cleaning ring is disposed around the inner cleaning disk; a base gear located in the housing is fixedly arranged on the transmission sleeve, and a fixed gear coaxial with the transmission shaft is fixedly arranged in the housing; at least two connecting shafts which are distributed in a circular array around the transmission shaft are perpendicularly arranged on the base gear, each connecting shaft is sleeved with a second gear and a third gear which are able to rotate around a central line of the connecting shaft, the second gear and the third gear are fixedly connected, the second gear meshes with the first gear, and the third gear meshes with the fixed gear; a power mechanism for driving the base gear to rotate is fixedly arranged on the housing; clamping rings configured as circular structures are fixedly arranged a side face of the housing, teeth are distributed on inner sides of the clamping rings, the handle is rotatably connected between central lines of the clamping rings on the housing, connecting pieces only allowed to slide in a radial direction of the clamping rings are slidably connected to the handle, a clamping piece which is located on the inner side of the corresponding clamping ring and able to mesh with the teeth on the corresponding clamping ring is fixedly arranged at an end of each connecting piece, a button is fixedly arranged at outer ends of the connecting pieces, and a spring for driving the clamping pieces to move towards the teeth is arranged between the handle and the button. In the above solution, when the cleaning mechanism operates, the power mechanism drives the base gear to rotate, and the inner cleaning disk and the outer cleaning ring are finally driven to rotate synchronously in opposite directions through rotation of other components, such that bidirectional rotation is realized, and compared with cleaning machines with a cleaning disk capable of rotating in one direction, the bidirectional cleaning machine provided by the invention has a better cleaning effect. Users can rotate the handle to adjust the relative angle between the handle and a body of the cleaning machine only by pressing the button; after adjustment, the button can be released, and the clamping pieces mesh with the teeth under the action of the spring to lock the handle and t
